Noise Control Continues

With Summer tour dates heating up, and our favorite festivals appearing to be taking the Summer off, I was lacking an out-of-town overnight show to really kick this effort into high gear. Well... Phil Lesh and Friends have announced Pacific NorthWest tour dates, hitting 2 of my all-time favorite outdoor venues: the Cuthbert in Eugene, OR and the Marymoor in Redmond, WA. Phil played these 2 venues back-to-back with Further in 2013 (See Tale of 2 Trips), so I conclude that these are his favorite NW outdoor venues too. Anyway, June 11 and 12, Phil will be at the Cuthbert and Marymoor respectively, and so will we. With that, we have some serious motivation to have Hapy buttoned up by the end of May. In that spirit, I finally got after the big sections of the floor, so today's post is all about that. 

Tear Down

starting the Jute

I accept that maybe I have been finding ways to delay the full-blown interior tear down. I messed with electrical (See Ceiling Wiring Rough In), built a replacement shelf (See New Cab Shelf), even messed around with the stereo (I will post on that once it reaches completion). At some point, I was going to have to remove the lot couch and the rock-n-roll bed so I could get after the floor underneath them. The lot couch removes easily enough, but the sliders also needed to come out so I could get the complete floor. Back when I first installed these runners, I mounted the runners with 17mm bolts. I added nuts underneath. I initially just loosened the runners and forced the Jute underneath. I later decided to completely remove the runners so I could get a seamless heavy vinyl sheet down.

My implementation of the rock-n-roll bed is held to the floor by a pair of Phillips screws holding a pair of arms to the rear deck, a 17mm bolt underneath, a pair of small nuts on a metal bracket mounted on the passenger side rear wheel well and a single 13mm bolt through to the fridge cabinet. The electrical bits, however, add to the complexity. I have my luxury fuse box under there, so I had to tear down what was left of that. Plus, the original Westfalia electrical includes the cables routing city power into the rectifier (110 to 12V converter) that's buried inside a wood box and running to the outlet on the front face of the bed. The box is held down with 2 Phillips screws and the outlet box is held by 4 Phillips screws. With the electrical separated from the bed, and the bed detached from the floor, I removed the cushions to manage the unit better. Each of the 2 cushions are held to the bed with 4 long Phillips bolts on each end (so, that's 16 bolts).

cabin Jute mostly complete

I would have completely removed the fridge cabinet, but the mounting of the furnace was so difficult, I did not want to revisit that. Just being disconnected from the rock-n-roll bed loosened it enough for me to fit materials an inch or so underneath it.

Constrained Layered Dampener (CLD)

I have probably posted enough on this material. Still, I applied on the now exposed floor areas. Parts of the floor had already gotten a light treatment in the little valleys, so on top of that I applied larger squares of CLD as well. I still have about a third of the box of ResoNix, with a plan to use some inside the sliding door. I have used some of the Noico around as well. For example, the walk-through partitions behind the front seats each got a large splat of Noico. I do not know if I will be keeping those partitions long term, so I did not want to spend the expensive CLD on those panels. Still, the Noico definitely helped reduce the clatter heard when I tap on the partitions with the roller. Of course, the whole floor and the rock-n-roll bed needed a thorough cleaning, starting with a shop-vac and ending with cleansers. 

Heat Wave Jute

MLV over engine

I was so excited to finally get to the Jute. I has felt like forever since I ordered this stuff and started working on noise containment. I started with a rectangle on top of the engine access hatch, with an extra couple of inches all the way around. I pulled the computer cover, and Jute'd the rest of the rear deck, and then moved forward. I fit a segment under the rear edge of the fridge cabinet, and doubled up over the front side of the rear driver wheel well. I pierced the Jute for the seat belts and a grounding screw, and set another piece of Jute up to the lot-couch rear slider and continued my way forward, covering the entire floor with rectangles. My method was to define as large a section as I could easily manage and then measure that out on the material. I marked the line with a sharpie and then traced the line with a box-cutter to start the cut. I made a second pass with a pair of scissors. I tried first with just the scissors, but the thickness of the material and 2 foil-faces were too much even for my best pair. As I set shapes down, the bus got progressively quieter. Without a radio, and just ambient neighborhood noise, there was not a dramatic change, it just felt more and more quiet. Very neat. One last observation about the Heat Wave: the foil top and bottom are electrically conductive. So, I would discourage use anywhere near open circuitry or be sure to insulate. For example, I took a section of excess MLV produced below and have it resting between the foil and the spare tire well where the engine computer and fuse box live. No sparky.

Lot Couch Rails

I had loosened the rails enough to force-fit some of the Heat Wave jute underneath, but decided that getting the MLV under the rails would be worthwhile. This meant removing the rails entirely. I had forgotten that when I first installed these rails, I ran bolts from above and nutted from below. Three of the 4 nuts were hidden by the radiator, so getting in there to free them was an all-morning exercise. Still, the nuts came free, the bolts pulled out and the rails were set aside. I took this opportunity to clean under the rails as well as install 4 riv-nuts into the old holes, so I would not have to go under the bus and reach around the radiator to deal with the rails again. That riv-nut kit is definitely paying dividends.

Mass Loaded Vinyl (MLV)

MLV continues

MLV is heavy; my goodness, it is heavy (1 pound per square foot). I found that the sound inside the bus actually brightened a little bit as I set it on top of the Jute, though. The Jute, in contrast, was simply amazing in how much quieter the bus seemed as I added it to the floor.  While I can't measure the impact of the MLV independently of the rest of what I am doing, I do wonder if the additional weight will translate into a corresponding reduction in noise. The SecondSkin web site has a noise transfer reduction table for the MLV that defines the reduction as anywhere from 14dB to 37dB, depending on frequency, with higher frequency blocked more than lower. We'll see. The actual absorption by the Heat Wave was noticeable. The table on the SecondSkin page for Heat Wave (in coefficient rather than dB) demonstrates very little in terms of dB drop below 500Hz: below 500Hz < 3dB, 1k: 7db, 2k: 14dB, 4k:19dB. So, the very high end will be controlled well and the low end not so much. I arrived at these numbers courtesy of the formulas on this blog post, converting the coefficients published by SecondSkin.

Anyway, the MLV delivers in a roll 54" wide. The bus is around 60-1/2" wide so rather than solve for a strip along one side, I laid a section 54" long front-to-back, covering the engine compartment and on down the rear wall behind the rock-n-roll bed. After cutting contours for the narrowing of the rear of the bus, I pierced the MLV for the seat belts and installed them. This took a considerable amount of time, mostly because of the challenges of getting the seat belt mounts in place. I continued with the next sheet of MLV, covering the mid-floor past the lot-couch rail mounting points (see picture above, right).

Re-Assembly

bed and rails in

I chose at this point to re-install the rock-n-roll bed. Unlike the seat belt mounts, locating and piercing for the bed mounts was much easier for some reason. With the bed in place, I pieced holes for the lot-couch rails and installed them. To make a more firm mount to the floor, I added a nut between the rail and the floor for the bolt to pass through. These nuts act like a 3/8" riser through the Jute material. I confirmed the width of the rails (12") and then torqued the bolts. Then, I put the lot couch back in. The couch slid in more easily than it used to. I think the rails were slightly below the lip of the sliding door before, creating some friction/resistance. With the little risers, the couch slides right in. The interior is pretty much the way I started the weekend. Yes, from the start to end of this post, it was 2 full-for-me (6+ hours) days of work, and some uncovered sections remain.

On a random mid-week afternoon, I added an additional strip inside the rock-n-roll bed where the 2 larger sections meet as well as a small piece inside the fridge cabinet. Last, the area just in front of the fridge cabinet shown in the picture above was addressed. So, from the seat partition rear-wards is pretty much done. That leaves the cab still to do. All of the seams need to be taped as well, but that should be much easier once the rest of the Heat Wave and MLV have been laid out.

In case you were wondering, that reflective material in the wall behind the fridge is foil-backed "RV insulation" that I had put in there years ago. It actually does reduce the temperature inside the bus a little bit, or it did when I first installed it. Since it does not fill the cavity, I will probably just leave it and put the Mega Zorbe or Jute right on top if it. There is the old Q-Quiet vibration absorber on those panels as well, and I will just leave that be. I am running out of material, and this project has taken quite a bit of time already.

That's it for today. Thanks, as always, for following along-

Hapy Seating

Over the years, Hapy has had 3 sets of front seats. Today, I start down a path of a fourth, and hopefully final, set. For the curious, I continue to Bondo-cycle on the replacement front fender for Zed, as well as sort through the garage. Boo and I have been taking advantage of the waning days of "decent" weather (read: light rain, around 8*C / 45*F) to get some hikes in before late Fall weather really kicks in. So, large steps forward on any car project is not happening right now. Sometimes, you just need to spend some time on a project that you actually want to do. These days, neither the Zed nor my garage are that project, but they are each getting some of my attention. So, as a distraction from that, I'm looking at Hapy's seats.

Seats 1-3

the '74s

I suppose it makes sense to start with what Hapy has had for seating. First, he had his original manufactured-in-1971 seats. These were built before headrests, and while they looked the part, they were completely clapped out, sagging painfully across the entire seat base. The horsehair stuffing was mostly gone and the fabric was dry-rotting away. So, while I was still working in Old Town (an area of downtown Portland now called "the Pearl District") I bought a set of blue-green plaid 1974 seats off craigslist for $20.

The blue-green set were marginally better. Maybe. The seats had been rebuilt at some point with foam, but I discovered along the way that they were getting ditched for $20 for a reason: they were very uncomfortable. Still, they were the seats I had, and they had headrests for better neck protection in an accident. After a few months with them, though, I would have probably gone back to my originals if I had still had them.

A few years ago, GratefulEd swapped out his original 1973 seats with minivan seats (which look and seat great), so he loaned me his seats while I figured something out. The 1973 seats served GratefulEd just fine, but they, too, were worn out. The fabric is so destroyed that the simple aftermarket seat covers cling to the foam underneath, not the seat fabric. Again, these seats are not the most comfortable, but they are better than the '74 set. GratefulEd put many miles on these seats. For, like, 2k of those miles, I rode with him. Still, at some point he wants these back, and at some point I would like a seat that will improve the ride... like the seats he put in Belle.

New Seat, What a Treat

Yeah, I've used that line before. In my scouting around craigslist, I found a set of "comfort" front seats from a 2016 Sprinter for $250. The "comfort" seats are so labelled because they have things like angle control and lumbar support that the "standard" seats do not have. Coming from seats that were little more than an uneven pile of flattened foam wrapped in shredded cloth, these things are puh-lush. With an arm rest. I read reviews of these seats where authors described taking road trips of 8-12 hours and not suffering from leg or back aches or any additional fatigue they could assign to their seats. Sounds perfect, but are they 10x better than those old ratty '74 seats I bought 15 years ago? I think so.

I drove over to the seller in Hapy. Upon arrival, I pulled the front passenger seat out of Hapy and set the Sprinter seat in it's location. It fit well enough to know that it could probably work, and then I jumped in to test-sit it. Ultimately, figuring out how to mount it, deciding whether I go whole-hog and do a swivel-seat upgrade, etc, all only matters if the seat is comfortable for a long drive. Just because some random internet authors said so, doesn't mean it will work for Boo and me. Of course, sitting in a seat for a few seconds won't tell the story either. But, I liked the seats, so I paid the guy, put the seats in the back and headed home. Hapy ran great, by the way: no codes, no stammering; he just cruised and felt peppy.

So, Will It Fit?

extra surround
getting cut off

Before I go too deep into the install, there are some basics. The Sprinter seats are much taller and the bottom is much thicker than any of the stock bus seats. When I placed the seat in, the headrest sat about an inch or so below the ceiling. Because of the original mountpoints in the passenger seat pedestal, I could not position the seat on top of the inner flat very well. As a result, I could only sorta-kinda get a sense for how it would be before the inner seat rail slid down into the well in the middle of the pedestal. So, regardless of what I do, that old passenger-side mountpoint will need to get cut off.

A little concerned about how the driver-side would fit, I pulled the '73 driver seat out and set the Sprinter seat in its place when I got home. This made for a much better assessment because the stock driver seat is mounted with toothed sliders, not large C-hooks sticking up from the pedestal. Still, the height of the seat base wedged my legs under the steering wheel. I confirmed that the seat will be very comfortable, once I have figured out how to lower them. These are built for delivery drivers, service folks and RV's: designed to be sat in a lot for long periods, and Sprinter's are not cheap, so the seats are a reflection of that as well (read: these are good seats). I will not have to cut out the partition for the seats to fit, but removing the partition could make them more adjustable.

Seat Gets Trimmed

While I did not have to cut up the bus, I did have to cut a section of plastic off the seat base. These seats are adjustable in 3 ways: height, seat-back tilt, and seat-base tilt. The height is controlled with a lever on the outside along the base, and it raises / lowers the entire seat above the rails by as much as 3 inches. In the Sprinter, the seat is bolted to a pedestal that is smaller than the seat, so when it is lowered, the bottom plastic surround drops below/around that pedestal. This will not work in a bus installation, as the pedestal is larger than the seat.

new seat (with surround removed)
versus old seat

The plastic surround, however, seems almost designed for this modification. There is an indentation that runs along the lower edge of the cushion, maybe 3 inches above the bottom of the surround (see picture above). I scored this indentation repeatedly with a box-cutter until the lower section fell off, halving the plastic surround's height. The new now-the-bottom sets slightly above the seat rail at the seat adjuster's lowest setting. With this lower surround removed, the seat rests cleanly on the bus seat pedestal (see picture on the right). For a longer legged driver, there are now a few inches of headroom, if the seat needs to be raised.

Install Thinks

Boo and I would love to have at least the passenger seat swivel, if not both, to create more usable space while camped. But Hapy has steel partitions behind the front seats. Those partitions, I think, were critical for collision safety since the back of the passenger seat was literally mounted with a hook-and-ring connector thing to it, and the seat was unable to sit upright without leaning against it. Still, these partitions could also represent some stiffness in holding the sides  of the bus square against twisting or in case of an accident. So, we have a few options:

1. *Mount the seats in a forward-facing-only orientation, bolting the slider rails to the bus.
2. Remove the partition behind the passenger seat, install angle iron to take up the side-stiffness, install a swivel base and the seat. Driver side remains just like option 1.
3. Remove the partition, but don't install a swivel. Maybe, the seat is just removed, reversed and re-installed facing rear-ward when we camp? Maybe instead of using bolts, the seat is mounted with nuts on studs, making the reverse-swap that much easier.
4. Remove both partitions, install an angle iron for each side for side-stiffness, install a swivel on each side.
5. Blending options 3 and 4, remove both partitions, but don't install any swivels. One or both seats could be mounted rear-facing when camped.

both seats mocked

My biggest question for whether options 4 or 5 are possible circles back to the steering wheel. Unlike the passenger side, where there is a big open space for the seat back to go when you face it rearward, that wheel is big, and sticks pretty far back from the dashboard. Just looking at the picture on the right here tells the tale. It is hard to imagine that driver seat facing rearward. Frankly, I'm going to have to think carefully about how to just install the driver seat. Use of studs may be necessary simply for that. I asterisked option 1 since that's the most direct option that gets seats in. I can always grow from there. Knowing that any swivel is going to raise the seat more, all the others may not be real options.

Some Prep Is Universal

Regardless of what we choose to do, there are some universal steps I need to take. First, of course, is addressing any rust on top of the seat pedestals. I removed the pedestal carpet a few years ago, and need to re-install it or cut some fresh carpet to install there. I intend to add some noise reduction stuff while everything is open before the carpet goes back in. I would like to move the brake fluid reservoir down into that below-the-seat area to simplify things a little bit. This would also create more possibility for a driver-side swivel (though that is still very remote). I may need to cut off the old driver-side seat tracks, if I run into issues putting holes through for the Sprinter seat rails. On the passenger side, the pointing-up C-hooks need to be cut off. You can see how they interfere in the mock-up picture on the right, here: the seat is pushed further forward because of where the C-hooks are. All of these (except the carpet install) can be done while I mull-over whether I am going to cut off one or both partitions. 

Boo and I tried sitting the mocked up seats just like the picture above shows. Overall, they are very comfortable. They do sit high, though, for our shorter-than-average-for-a-US-person legs. I can fully activate the pedals all the way to the floor, though. For Boo, she may need something under her feet for longer drives so the leg-dangle doesn't negatively impact her lower back. I'm sure we have something that usually travels with us that could stow there which would meet that need. In the past, she has sat with her feet propped up on the dash, so a more permanent step isn't necessary. The partitions do impact the degree to which the seat-back can be tilted. For the driver, I'm not sure how much it matters. For a passenger who sometimes likes to sleep on the drive, this might lead us to removing that partition eventually. At this point, I am going to work on simply mounting the seats and leaving the partitions. We figure I can always circle-back around on removing a partition, but once it's gone, it's gone. Maybe there's a way to just lower the passenger-side partition a couple inches to enable a seat tilt.

That's it for today. I'll post more on this progress as there is some, leveraging the old "Part (x)" to keep them strung together. Thanks, as always, for following along-

New Seat, What a Treat - Headrests

This is the final installment of the seat reupholstering effort. I have stripped down, sanded, rust-treated and painted the original seat frames (in Part 1). Onto those frames, I have installed the seat webbing (Part 3), new hard-backs (Part 2), foams and covers (Parts 2 and 3). The seats have been installed back into the little car, with head rests, but I have not yet talked about that upholstery effort for those. I will cover that today.

Headrest Extraction

First, you need to separate the headrest from the seat. Obviously, but it's not that easy. With a convertible, moisture gets everywhere. In the Pacific Northwest, moisture gets everywhere. Add those together, and moisture truly gets everywhere. Even into the headrest tube, and enough of it to rust through chrome. My driver seat was easy, but I had to resort to these more drastic measures for the passenger seat: with the top down and the seat still bolted to the floor, stand behind the seat, place one hand on either side and lift as hard as you can. If you are lucky, it will come flying out, bang against the ceiling and not hit you in the head on the way down. If you are unlucky, you may just hurt your back, and the head rest is still stuck. Seriously, these buggers can be that stubborn. Use your best judgement, but it needs to come out to do the seats at all, so if you cannot get it free, forget about recovering your seats.

Old Cover Off
Once in hand, look at the underside of the headrest. There is a plastic strip that runs along the bottom which is held on with 2 Phillips head screws. Mine were really rusty (so I ultimately replaced them) so I needed to take care coaxing them out. If you keep yours, it may be worth soaking them in vinegar to get them rust-free Set the plastic strip aside for cleaning with dish soap and grab a thin slotted screw driver and a pair of needle-nose pliers. The plastic strip covers up staples which hold the cover on. With the screwdriver, work the staples free enough for you to grab with the needle-nose pliers and then pull the staples out. If you are not concerned about the old cover, you can tear the cover off and pull the staples afterwards. I prefer to not destroy things, but everyone is different.

With the staples out, the cover is only holding on through friction. Pull the cover and the foam off of the head rest stem. Do this whether you are reusing the foam or not. If it is original foam, I strongly encourage replacing it, though it can be hard to locate for some cars. I found the MGB headrest foams at Mirror Trim in the UK, and while the cost is a little high, it was worth not having the old foam disintegrate while installing.

Repair and Rust Treat
In my case, there was rust on the square metal head rest "head" as well as down near the bottom of the chrome post. The wood into which the staples were driven was shattered in the driver-side headrest (passenger side wood was in great shape). So, there was some repair and rust treatment needed. First, I taped off the top 3 inches of the chrome post with painters tape. This part of the post on both headrests was in decent shape, and I was opposed to painting them. Once taped, I sanded the "head" thoroughly and scuffed the rust off the chrome below the taped off section. I felt this chrome would not be seen, but needed to be clean for the head rest to work better. Then, I shot the "head" with some gloss-black Rustoleum and removed the tape. The wood strips in the driver head rest needed to be replaced, so I took one piece that was still intact and used it as a pattern. From my woodpile I found a strip of cabinet edging that was the right height and width, and cut two pieces to length. Before I started re-assembling, I cleaned the plastic strips with dish soap and found 4 Phillips head wood screws which would fit through the holes, sit flush once installed and were about the same length as the originals. I used "size 6" thickness, 3/4 inch long wood screws.

Re-Assemble

The headrest foam and cover are not uniform. Both are side specific (front and rear). The nicely tailored edge is on the edge from the front while the un-hemmed edge runs from the rear, and under the front, hemmed edge. The foam is thicker in the front than the rear, but that part is a little more obvious. Similar to stuffing a pillow into a pillowcase, stuff the foam into the cover, making sure that the corners are in the corners and the edges align with the edges. The foam is way bigger than the cover, so I used my thighs, arms, and abdomen to get the foam into the cover. Then, it was a considerable finger exercise to get everything aligned. Once set, though, you will see a slot in the foam for the "head" of the headrest to slide into. With the glossy paint, it slides right in. On the passenger head rest, I found I spent more time fiddling with the head rest post to get it at a depth I liked, but you may not have that issue, as I did not with the driver side. Shrug,

Staple and Screw
Before you grab your staple gun, I suggest that you take your nice and clean plastic strips and test fit them. Similar to the foams, the strips are not mirror-images, the rear side is thicker, but the distance from the post to the screw hole is the same on either side. So, consider where the screws will go, and then plan your staples. Remove the plastic strip, pull the rear flap forward, and under the front (hemmed) flap and hold it in place with your finger. I held it in place where the screw hole was so I would not lose track of it while stapling. Check that you are centering over the wood and place at least 1 staple on either side of the screw hole. There were 2 per side originally, so I did the same, making sure that the amount of stretch across the headrest was uniform as I did. There is a lot to keep track of in order to make it look good and lots of ways you can lose focus so it looks bad. Just do not staple until you are sure.

Once the staples are in, the hard part is over. Slide the plastic strip back into place and screw it to the "head" with rust-free screws. If you ever wanted one of those seat belt keepers (like these in the picture), now would be the time to install them. I do not like losing my seat belt, reaching around for it nor having it bang against the car when I take it off. These little plastic keepers really help, though getting access to a parcel stowed behind the seat is not as easy.

Re-Install
This should be straightforward. In my case, the seat foams were manufactured without holes for the head rests. Perhaps the seat foams were developed to span many years, including years without head rests. Regardless, If you did all-new foams like I did, you will need to find the rectangular hole with your fingers and cut the foam. Take care as you align the cover, the foam and the head rest post. Do not simply grab the chrome lip on the seat cover and push/pull. The chrome lip will easily separate from the cover if you do that. Once you find alignment, trim what little foam you need to and slide the head rest into the seat. I took an extra minute and applied some PB-Blaster brand white lithium grease to the post so it would move more freely in the future. I also applied this grease to the cleaned-to-the-steel seat rails and workings so the seat would slide forward and aft more easily. These little final touches really made a difference in the usability and perception of the seats once you were sitting down in them. I highly recommend taking the extra few minutes to apply the lithium grease.

So that's it. Over the course of about 2 days per seat, they are completely renewed. New foams, new webbing, new covers from top to bottom. The headrests are more functional, the seats tilt and move more freely. Most importantly, they are comfortable. Now that they are installed, I will either finish the wiring of the seat heat, put some effort into the amplifier for the speaker box or carpet the trunk. I will see how I feel when I get to the garage.

Thanks, as always, for following along.

New Seat, What a Treat - Part 3

Today, I'll complete the story of getting the driver seat stripped, recovered and installed. When we left off (See New Seat, What a Treat - Part 1 and Part 2) , the old covers had been removed and set aside with the old padding, hog rings and ratty hard-back. The upper seat had been re-foamed with a heat unit, and recovered with a new hard-back. Now held in place with hog rings, it is a completed unit.

Back to One Frame
Before getting to the lower seat, the upper and lower halves need to be put back together. This is quick work with a couple of 1/2" spanners per side. Over each of the hinge points, a plastic protective cover is installed. These keep fingers, cover material and grime from getting into the hinges. They are held on with a single Phillips screw each and are side specific. I had washed these with dish soap, removing 30 years of gross beforehand. At this point, I tested the action of the seat release lever and the movement of the hinge to make sure nothing was binding and that it had a smooth movement. Check.

Lower Seat - Webbing
The upper cover was similar to a pillowcase, with an opening at one end (the bottom). The lower cover only has 4 sides: top, front, left and right. So, it is more like a fitted table cloth. No forceful stuffing to get everything to fit this time. While that sounds easier, the material does not stay put as easily, so I found myself double and triple checking everything at each step.

First, we start with the webbing. I found little advice for how to do this, and based my entire plan on pictures I found on the internet (like this one on the right from MGExperience). The webbing has 4 straps which run left-right and 2 straps which run front to back. These straps are loosely threaded onto a thin, 3-sided, u-shaped metal bar (I'll refer to as the U-bar). The replacement kit arrives with 12 little hooks which hold the webbing contraption to the lower seat frame. The frame has 16 little holes: 2 along the front, 2 along the rear, 5 along each side... and one in each front corner. Apparently, those corner 2 are unnecessary and there is an extra pair along the sides for personal comfort configuration. The bottom of the "U" faces the front of the seat, so the 2 holes in the rear of the frame are for floppy straps that are not dire-connected to the thin metal U-bar. I started at the front, threading one hook each through the gap at the end of the strap, around the U-bar and then into the hole in the frame. With the front done, I worked my way down to the rear, doing holes a strap at a time, one side, then the other. I left the last pair, closest to the rear unused, choosing for the more forward pair thinking it would be more supportive. Last, the rear-end of the straps are hooked into the frame. To help prevent the straps from cutting through the foam, I put a small thin white hand towel on top of the webbing. Others use burlap or canvas. The hand towel was available, free, fit, and will do the job at least as well. There was nothing between the foam and the webbing when I tore the seats down.

Foaming
Unlike the upper seat covers, the lower seat covers and foams are side specific. On the underside of the foam, you will find either LH or RH embossed into the foam. This is because the little notch-outs nearest the seat hinge are not the same. Also, the seat edge along the transmission tunnel is more straight and narrow than the seat edge which runs along the door sill. This allows the seat to move forward and aft on the seat guides much more easily, without hanging up on the transmission tunnel. Since your backside sits in the wide center anyway, you may not really notice. The covers are cut differently, just as the foams are, so match them carefully or you'll be re-doing part of the job. Ask me how I know :)

Lower Seat - Covering
With the webbing in, I pushed the lower seat foam onto the frame and took a seat. Wow. It was like the difference between an old saggy couch and a nice new desk chair. Firm, but totally comfortable; I felt I could sit in it for hours. Those few minutes were inspiring. I pulled the foam and attached the other seat heat unit to it. Similar to the upper, I didn't cut the heater. Instead, I ran it from just behind the front edge all the way to the front edge of the upper cushion. I'll have warmth from the back of my knees to the top of my shoulders. Ha! Once I got the double-sided tape figured out, it attached and held well through the process. For more wiggle room, I tilted the seat upper slightly forward. I took out the new cover, oriented it where it belonged on the foam/heat unit pair and pressed it onto the frame. I say "pressed" because with the seat upper, it took more than just setting it. There was resistance to my getting it all the way back in place. Again, there were many cycles of fitting, adjusting and re-fitting to get the foam aligned with the seams. Minutes taken here are where you'll see the difference in the finished product.

Ring It Up
With the seat bottom where I wanted it, I tested it again (Ohh.. soo nice). If you are following this as a how-to, I strongly encourage you to try this in-the-car! You may find the seat too high. I, regrettably, didn't do this test. Instead, I started on the hog rings. I made sure the heat unit wiring was on the transmission tunnel side, like the upper. With the seat upper helping hold the rear in place, I started there (along the rear) with the rings. Like the upper, I pulled the material until it was well aligned and put 2 rings about a fist apart in the center. Again, following the pattern from before, I did each side of the rear, checking for alignment. Then, I switched to the front, and followed the same pattern: center first, then outer edge, checking for alignment, no wrinkles, etc. Last, I did the rings along the sides, starting with the edge nearest the transmission tunnel. Since the hog ring pliers I got at Harbor Freight were useless, I used my fingers to get them in place (not easy) and channel-lock pliers to snug them down.

Install
So, there were things I did, and things I would encourage others to do differently. I changed my disposable gloves often so I would keep the seat clean. I covered the seat with a large trash bag for the same purpose. One of the things I had failed to do was test out the seat in the car before hog-ringing the lower cushion. Had I done that, perhaps I may have omitted one or more of the webbing straps. I say that because with all of the straps in, and the seat tilted fairly straight up, my line-of-sight out the windscreen is too high. Since the straps are what hold the foam up, I could have tested, removed one, tested again, etc before putting on the cover.

Instead, I carried the finished light-cream-colored seat into my cramped, filthy garage. I held it overhead and found that getting it into the car with the top up was simply frustrating. So, the seat went onto the dinner table while I lowered the top. Take 2: carry the seat high overhead, lowering into the cockpit. For some reason, all of the challenges I expected when I put in the old seats on top of the new carpet happened this time. I couldn't find the holes, then, when I found them, I couldn't get the bolts to thread. Then, once they were finally threaded, I realized that the seat runner was oriented incorrectly.... Last, one of the worst things happened: the front outer bolt and captive nut pairing got stripped.

Fix It

The bolt wouldn't come out of the captive nut, so the captive nut had to be separated from the new floor.... while holding my light-cream-colored seat loosely on top of it. I went the brute-strength method and used a pry bar. In retrospect, this was a great test of the welding of the floor we had done; the welds held better than the sheet metal. The nut released from the floor, the seat was returned to the table and I went looking for a replacement nut. I found one, and, with the welder I had used 18 months earlier to install the floor, I welded that nut into the hole created by the removal of the old one. I covered everything with canvas painting tarps before I welded so any possible errant spark would not land on my new top or new carpet. Since the top of the new nut didn't sit exactly flush with the floor, I slid a washer on top of the other front seat-mount hole to level the front of the seat. I left it alone overnight and the next day the seat went in easily.

I fiddled with the seat incline and found a spot that, while tilted a little further back than I usually drive other cars, the angle totally suits the MGB. This little car has a deep foot well and a short reach of the steering wheel, so it is almost designed for someone who has long legs and a short torso and arms... until you tilt the seat back a little bit. Now, instead of having the steering wheel nearly against your chest, you have some living space... and the angle lowers your line-of-sight through the windscreen such that your eyes are below the sun visors.

That's it for today. I will wrap up with a post about the head rests. Thanks, as always, for following along-

New Seat, What a Treat - Part 1

I had a few days off, so rather than spend them playing in the snow or taking a personal trip, I stayed home, and re-upholstered the driver seat of Oliver, the MG. Today's post covers the start of that journey. Sorry today's post is a few hours late.

Old Seat Out
Remember when I installed the old seats on top of the new carpet (See MGB - carpeting (part 2))? Even with the nuts jammed under the seat rails, the seats placed the driver kind of low in the car. Sure, it is a little British car, so you're supposed to sit low. But, there are limits. I figure my eyes should be about 2/3 of the way up the windscreen, and I was around halfway. It felt like I was sitting a hair over the floor, suspended by the vinyl seat cover and little else. I had planned to replace the seat covers, foams, etc last Spring when I had the small win-fall that netted me the new carpet. I just hadn't gotten to the work because I had other things going on, and I wanted to drive the car. So, with this small break, I had my chance. Starting with a basic 7/16" spanner, I removed the 4 bolts which held the driver seat to the floor and removed the driver seat.

I moved the seat upstairs to the shedroom. That room is clean, and all of the interior bits are stored there, so it made more sense than trying to do it in the packed garage or in one of the general living spaces. First, the headrest needs to come off. With the seat on the floor, I stood on the seat bottom and whip-sawed the headrest: pushing it all the way down and then yanking it back up. This violent push/shove blend actually worked, freeing the headrest in a handful of reps. I set the headrest aside, and moved to the Lower Cover.

Old Lower Cover Off
The lower cover is held on with 4 sets of 4 hog rings: one set along each of the sides. I was able to work them free with a small slotted screw driver, exposing the padding underneath. The padding was orange and tattered near the edges. When originally constructed, this foam would sit on top of a 3-sided metal hoop to which 6 rubber straps are attached. This webbing creates a little give to the seat, and provides the lift from underneath. On this seat, the webbing was in disarray. Most of the ends were disconnected and tattered. Fortunately, I had a replacement set for the refresh effort. The pad, cover and webbing were tossed towards the shedroom door and I shifted to the Upper Cover.

Old Upper Cover Off

The upper cover is held on with 4 square clips along the back and 4 hog rings below that, holding the front down. The hog rings flew off with a little pressure with a slotted screwdriver. I did my best to not damage the cover. The square clips needed more coaxing, and since I did not know about them, I had not ordered replacements, so I needed to be careful with the originals. Before the cover will slide off, the seat-angle arm needs to be removed. It is held on with a Phillps head bolt. Once the 2 sets of clips and the angle arm were removed, the cover slid right off the top.

Within the cover, I could see a few interesting things. First, the original foam was orange, and had tattered along the edges. The "hard back" was cardboard that appeared to not be original, nor standard-issue. It looked like a square of cardboard had been cut from a shoe box, or something. It had been taped, with duct tape, to the orange foam. Cool. The tape, cardboard and foam fell apart without much prompting. I think the cover was holding everything together. I tossed the mess atop the Lower Cover mess.

Separate
Now, I was down to the metal. I could see the rust spots, and recognized the need to address the frame. There are 2 plastic hinge covers that protect fingers and the covers from the seat hinge. These remove with a Phillips screwdriver. With the plastic covers set aside, the bolts that represent the hinge can be removed with 1/2 inch spanners. Before I could deal with the rust, though, I removed the seat runners from the bottom of the seat. Moving the seat forward and backward had become difficult, so I wanted to get all that nasty grease and grit out of the runners. I took the seat frame and the runners downstairs, and then focused on the head rest.

Headrest

The seam for the headrest cover is on the bottom, hidden by a small plastic strip, held in place by 2 Phillips screws. With the plastic strip removed, the staples which hold the cover on can be addressed. I used a small slotted screw driver to loosen them, and finished the job with a pair of needle-nose pliers. The cover slides off fairly easily at this point, taking the old foam with it. I had new covers and new foam, but I hadn't anticipated small wood slats along the bottom edge. It is to these slats that the staples and Phillips screws attach. Not all of the wood was bad, but the bottom-most pieces were. I took one good sample from each side and cut pieces that would fit from some scrap wood I had lying around. In a pinch, you could cut up a paint stir-stick: it is the right thickness. The key is finding something thin enough to fit in the channel along the underside of he headrest.

The headrest steel was in a similar state to the rest of the seat frame: some surface rust spots, but no rust-through. I brought it downstairs as well, and moved all 3 pieces to the front porch.

Rust Treatment
Some aspects of working on cars does not change no matter what you are working on: dealing with rust. I attacked the rusty areas with 60-grit sandpaper and then sanded the whole thing with 100-grit. This left a decent edge for paint to bite into. I painted all surfaces with Permatex Rust Treatment, and let them dry overnight. The following morning, I shot them with some black Rustoleum I had in the garage, and hung everything to cure on the front porch with bailing wire.

All of the random other bits got the cleaning treatment. The seat runners, for example, were soaked in de-greaser and cleaned up. All of the little plastic bits and handles were deep cleaned as well. Even the fasteners which I intended to reuse were cleaned up and scrubbed.

I was feeling pretty good at this point. The tear down was easy, the rust invasion was not too bad. I figured the easy part was over, though. Turned out, I was right, but I'll get into that next time. Thanks, as always, for following along-

MGB - carpeting (part 2)

This is a continuation of the previous post about installing the carpets into the MGB. At this point, I've mapped all of the various pieces of carpet to where they go in the car and I've traced and then cut thick or thin insulation to go under the carpet for the respective sections. Now, it's time to play with spray epoxy.

Back to the Directions

For the install, I followed the directions for the order which carpet first, second, etc. For each piece of carpet, I had something to go under it (except the transmission tunnel). For each piece which directed gluing straight to steel, I would test fit the insulation, then test fit with insulation and carpet. If necessary, I would trim the insulation a little bit so it wasn't visible. Then, I'd spray epoxy onto the insulation and install it, holding it in-place for a 30-count or longer. Then, I'd test fit the carpet on top of the glued-down insulation, then epoxy it into place by spraying epoxy onto the carpet underside. Remember to let the epoxy set-up a little bit before slapping the things together. Wet won't hold; it needs to tack-up a little bit: spray the underside well away from the car, let it set up for 15-30 seconds and then apply in-place. If you, the reader, are looking at this for guidance, take care with the transmission tunnel carpet. I realized after mine was in that a shifter cover plate hadn't been put back in, so I needed to cut a small line in my carpet in front of the shifter to enable that re-install. Since it will live under a console, it doesn't really matter, but I really don't like cutting when I don't need to. Honestly, it is really hard to tell that the carpet was cut there now even without the console.

No Glue, But No Snaps
The carpets that sit on the floor under the persons in the car and the piece on the back deck are not glued in. Instead, they were held in place with snaps from the factory. Since I replaced my floors, many of the old snaps were gone. I had a decision to make: install the snaps or try something else. Knowing that the snaps had to be in exactly the right place for them to align with the snaps in the carpets, or there would be lumps in my brand new carpet, I decided to not install snaps. But, I needed something to hold the floor mat especially under the driver's feet. Otherwise, it could slide around under the pedals making for a dangerous driving condition. I found Velcro at Ace Hardware that was designed for wet conditions and it could hold up to 30 pounds. Since we just need to hold carpet, this felt like a good way to go. I cut sections out of the insulation, glued the Velcro to the underside of the carpet and corresponding spot on the floor. Now, the carpet holds in place, and retains it's original ability to be removed for cleaning and access to drain plugs. And no lumps.

Cutting Holes
In order to re-install seat belts and the seats, this brand new carpet needs to have holes cut into it. I found this a little hard to embrace at first. Since I was putting insulation under all of the various pieces, though, I could figure out exactly where the hole was supposed to go with something that wasn't carpet and then transfer that spot onto the carpet. This worked well for the sill carpets (that section from the ledge along the bottom of the door to the main floor) where the lower seat belt mount hole is, but greatly complicated an already difficult wheel arch. Fortunately, the transmission tunnel carpet had the holes pre-punched. This made aligning the carpet easier in that respect, but made the overall install of that carpet much more harrowing because everything had to line up perfectly.... with epoxy sprayed on it. Move quickly.

The last holes to put into the carpets are the holes for the bolts to hold the seat rails. In the MG, each seat is held in with 4 7/16" bolts. The carpets do not ship with the holes pre-punched, so you need to locate them yourself. Not all of these holes pop out the bottom; in fact, only one does. The front 2 pass into a cross-member and one of the rear ones does too, leaving just the one. I started with just the insulation down, and pushed a finish nail up through the one hole. This removed front-back and left-right sliding of the insulation while I located the other holes. These, I found in a more traditional way of folding back the insulation until I could locate the hole, and guestimated where it passed through the insulation. While some holes took more than one try, I located the holes with finish nails, leaving them in the insulation for transfer to the carpet. Taking the insulation to a table, I set the carpet on top of the insulation and pushed the finish nail through the carpet, marking the hole, and then put blue tape on top of the nail to hold the mark. With an exacto-blade, I cut a small "X" at each nail, testing the size with the seat-rail bolt so the hole was only as large as needed to be. With the bolts pushed through the holes in both the carpet and insulation, I could set the carpet in place and then put in the seats.

Seats In

Once the carpets were in, I put the seats back in. The seats were originally installed with a wood slat running under the steel rail to lift it up off the carpet a little bit. Not surprisingly, these wood slats were rotted away. Instead, I boosted the seat up off the carpet by putting a slightly over-sized nut under the seat rail where each of the bolts passed through to the floor: one per bolt. These 4 nuts created little stands for the seat rail so it sits just above the carpet. I expected this to be a challenge, between the low ceiling created by the convertible top, the small holes, getting a nut under the rail, juggling an old seat, etc, but it really wasn't. The blue tape gave me clear targets for the holes in the seat rails so I could get the seat in the right spot without the carpet moving. Then, one corner at a time, I lifted the rail, slid a nut under the rail and the the bolt through the rail, then the bolt and finally into the hole in the floor. I would lightly thread the bolt and then move on. I tightened the bolts snug as pair: front then rear.

Finishing
I finished out the rough-in by making a small cut in the transmission tunnel carpet and installing the shift plate. I followed my now-usual pattern of soaking the old plate in vinegar for a few days to get the rust off; then, cleaned primed and painted it. The install of the plate was simple: re-use the 3 Phillips screws at the front. I re-used the original shift boot after cleaning it up with some Meguiar's vinyl cleaner just to get the shifter together and looking fairly good. I'll be switching out the shifter boot with the rest of the interior panels and seat covers later. The boot is held down with a new black ring and chrome bolts. The ring and bolts were less than $10US, but that change greatly improved the finished look.

I installed new door rubber seals and the stamped-steel transoms (with new screws) to complete the effort. The ends of rubber seals are held in place with small chrome bits, and otherwise just press onto the lip which runs along the edge of the carpeted sills. The stamped-steel transoms are held on with 6 small screws, and after some polishing, look fairly decent for original pieces.

Now, it looks and sounds like a "real" car. When the doors are shut and windows up, the car purrs. When I stomp on the fast pedal, it has a little roar to it. I still need to put the center console in (for climate control) and it could use a radio, but the little car is about ready to be a daily driver.

Thanks, as always, for following along.

Putting it to Bed

By now, most of the hard parts had been completed. Today's post covers the final bits and pieces, putting the project to bed, so to speak.

Rock 'n' Roll

bed, before

With the bare floor painted grey, the first of the last phase was getting the rock 'n' roll bed in. I'd pulled the contents out prior to its removal, but the bed is still pretty hard to move around by yourself. Still, with a mixture of dragging and heaving, I got the bed up and into place... without making the floor look too shabby in the process. Since the floor no longer had wood sheeting on top of it, getting the bed to align with the holes on the top of the engine bay wasn't quite as easy. It found it's home, though, and I was even able to get the little 2-bolt bit from the passenger tire well to slide home.

In the Light
Under the bed fits the auxiliary fuse box and battery. While in previous incarnations of this set up the battery powered a few different things, all it powers now are lights and 12V adapters. I already touched on some of this effort in an earlier post (see bump bump bump under "Cabin Lights"). Once locked in, I could move on to the refer cabinet.

bed, after

The Crunge
The fridge cabinet had previously just floated around, but I hadn't known that until removal day. Between removing the rear closet and the stove/sink, it held in place through simple inertia. There is supposed to be a bolt that threads into the fridge from the bed. That's now back in place and the cabinet is locked in tight. Between the fusebox and getting this cabinet in place, there were some wire-management issues too, but they're all well routed now, so no furniture is sitting on top of a wire. I still need to get the shore-power capable of charging the battery or simply feeding the lights and such, but that's something for another day.

Kashmir

middle seat in

We're getting near the end. I put in the rails for the middle row seat, following the holes and some blurry photos I took from the prior install. Without the wood floor in place, it seemed like the rails synch down tighter, but really, they were just lower, making the placement of the seat in the rails a little harder. After first just setting the rails in and finding that they were too close together for an easy fit, I took another tack. With the bolts in finger-tight, I tapped the rails as far apart as I could make them. Then, tightened them down for a fit. The seat slides in as easily as it used to (which isn't all that easy). I may need to Lithium grease the rails so the seat goes on easier.

In the middle picture, you can see that I've covered the rear driver-side window. I posted in "Whatcha Hiding?" about the screens I made a few screens to cover that window. As a final preparation, I painted the side that faces the inside of the bus with the same grey paint.

Well, that's really it for getting the bus back together. I was able to get it all done before the Memorial Day weekend so I'll post on that next time.

Vanagon Seat Install

Today starts my vacation, yet I'm getting one last post in before I go.  I wanted to give an update on both the Vanagon loveseat as well as the transaxle.  I've kinda wasted the afternoon, so I'll probably keep this short.

Love Seat

what goes with green/blue plaid,
grey, white, and blue?
Why, TAN of course!

Ok, maybe calling it a loveseat is a bit much.  Its a tan 2-seater bench seat from a brown Vanagon.  Once installed, I'll have a '79 Westy folding bed seat, front seats from a '74 and a bench seat from a Vanagon.  It will be a true franken-bus.  Sue me.  I'll be able to carry 5 people (plus me driving), and camp once we get there.  Try that with a stock VW bus.  Anyway, on to the progress report.  In order to fit the bench, I had to pull the stove/sink unit.  That cabinet now adorns my living room floor, but it makes ample room for the loveseat.  Once I made space, I aligned the rails with the seat by aligning the seat mount holes with the mounts within the rails.  I then duct-taped them together and put the whole operation into the bus.  With some wriggling, I set the spot front-to-back by lowering the folding bed and putting the bench up against it.  My thinking was that I may want or need to carry something long while also carrying some folks.  I was able to carry my entertainment center on that folded down section before.  Now I'll be able to bring 3 friends to help me move it.  Last time, I could only bring 1 friend... and he wasn't exactly thrilled at that prospect.

rear left rail location
westy fridge cabinet in
upper right corner

I marked up the wood floor with pencil so I knew where to put the rails and then pulled the seat out again.  Remove the rails from the seat and set the rails back in place.  I then set to measuring all over the place so I was sure that any hole I drilled in the floor wouldn't hit the radiator, the supports, the main front-to-back beams, the brake lines, etc.  I managed to miss everything important on my first try.  Hazah!  I drilled out 6 holes to 3/8" and wrenched bolts through.  From the underside, I lock-washered and nutted the bolts down. Last, I re-inserted the seat the "normal" way by sliding the seat onto the mounted rails.  Done.  All told, it took a few hours, but I move slow.

Transaxle
Well, we're behind schedule a little bit on the transaxle.  The CM code transaxle used the early gear sets and Daryl only had the later sets on hand.  With one of his guys out sick (or following a band around the country), he was behind schedule anyway, so this just put us a few more days out.  Unfortunately, those few days are probably the diffeence between having the new transaxle in time for the trip to Southern Oregon and not.  So, the bus may not go.  We'll see.  If the transaxle arrives tomorrow, there's still time.  I need a few days to do the work (see: I move slow) and we leave in the middle of next week.  Sigh.  So close and yet not quite close enough.

right edge of seat & slider

That's it for today.  The next time we go for a spin, we can carry the whole family.  We'll just be travelling at a max speed of 52MPH for now.  More next time and thanks for following along.
