Film at Eleven

With the start of April comes the Pacific NorthWest's faux-Summer.  We're really experiencing that now, with mid 70's temperatures, clear blue skies and bright smiles on everyone's face.  In an ironic contrast, I spent Sunday afternoon in my sun-blasted garage solving the water-block problem both under the belly-pan and in the passenger door.  I'll hit that today.

Plastic Fantastic

from vw-resource.com

First, I need to give credit where due.  I stumbled upon this website while trying to figure out a viable way of keeping the water that makes it past the window seals from damaging the new inner door panels / cards.  The old plastic was pulled out, and the cards were destroyed.  The guys at the vw-resource web site had a great suggestion for using BlueTak on their page dedicated to the doors.  In my last post, I mentioned that I bought some of the 3M stuff that was basically the same.  I borrowed their picture on the right here.  The 3M stuff is white, so it doesn't show up as well in pictures.  I posted one here anyway.

trash-liner door-liner

Note how much less I used (I relatively uniformly used around 1/4" thickness).  That became an issue when I tried to hang visqueen.  The plastic sheeting that you get in most home remodeling shops is too slickery, and won't stick easily.  Instead, I considered what was originally in there: a very thin film.  I grabbed a kitchen garbage bag, and hung it on there instead, aligning the bag bottom with the door top and one edge against the front edge of the door .  Because of the static electricity built up in the bag, it immediately clung to the steel, making the pressing into the 3M stuff much easier.  I cut the bag in half along the front / leading edge of the door, and folded it back against the rest of the door.  Some simple trimming later, and the door is sealed.  Like the vw-resource guys, I poked holes where the rubber bits will be going and made sure to run loops of sticky-stuff around those holes.  Be sure to run loops of the sticky-stuff around the holes for the window winder, door pull and the latch.  One other thing to note, I didn't run the plastic to the very bottom of the door; only to the very bottom of the hole in the door and then put multiple runs of sticky stuff along the bottom.  Remember, the whole idea is to keep inside the water that's inside the door, so it runs out the bottom.

Bag in the Pan

exposed electricals. 3M sticky

After such a simple success with the door, I slid under the front of the bus and pulled the belly pan off. My drive-by-wire electronics are under there.  This has been a source of concern any time I go for a drive when the pavement isn't dry.  While it is really just a simple resistor attached at one end to the pedal and the other to a wiring pigtail, its still an expensive replacement.  If it got wet, it would fry, and I'd need to replace it.  As I write this, I realize that there aren't any fuses in the wires either, so if something shorted out, there could be ECU troubles.  Anyway,  in looking at the exposed electronics, I noted so many openings where water could get through: from the rear where all the controls go through, over either side of the main frame members, etc.  Yikes.

same view, but bagged now

I had thought of plastic-sheeting the entire area, but that would have been nearly impossible.  Instead, I figured I could just "bag" the electronics by running a circle of sticky along the bottom of the floor and sticking another kitchen trash-liner against it.  It totally worked.  It has a small hole for the pigtail, but otherwise, its protected from water.  Once the rainy season returns for May and June (like it always does), the bus will be road-capable.

That's it for today.  I spent Saturday watching C play in 3 lacrosse games, starting the Spring sports season.  We hoped to hit Mt. Hood on Sunday, but it was raining up there, trashing those hopes.  I'm starting to believe that the Ski Bowl season is about over, between that rain and today's warm temperatures.  I've heard it will hit the mid 70's through next weekend.  So, after an unimpressive snow season, our Spring conditions appear to be disappearing.  Time to plan camping season instead!  Thanks for following along-

Thinking while Dinking

I unexpectedly had Sunday available to putter on the bus.  Boo was supposed to work, but suddenly didn't have a shift.  So, after a visit to the gym (I really need to do that more), I opened the garage door, turned on some tunes and pondered the bus.  Sometimes, you need to just be with your project to have an epiphany.  I had a flash of brilliance that (hopefully) could solve the wet-weather challenges for good.

Cutting Cards
I decided that a free afternoon shouldn't count in my build versus buy math since the afternoon was free.  So, I pulled out the Dremel and cut another door card.  Okay, back up.  First, I took the first door card I did and started trying to hang it on the passenger door.  I found little things that needed to get adjusted.  The grab handle holes weren't big enough.  Then the inner latch surround thing didn't fit.  Last, I realized that the holes for the door clips weren't there.  That was kinda fun, actually.  I took the ratty old door card and laid it on top of the new one.  I set those on top of a fresh piece of MDF.  Once lined up, I grabbed my drill with a 3/8" bit and bored straight through the door clip holes in the ratty door card into the new one and the MDF underneath.  Perfect.  I pulled the ratty card off the stack and traced the other holes and around the edge.  30 minutes with the Dremel later, I had a duplicate of the new card.

I still need to do a little sanding around the edges to make it a really nice fit.  The holes line up well and the grab handle, window winder and inner latch all mount correctly now.  Its just a little 100%-ing around the edges.

Hanging the Plastic Curtain
Originally, the early VW's had a "vapor barrier" between the door card and the steel door.  This was because no matter how good your seals were, water would seep inside the door, and could slowly rot the MDF/cardboard cards.  Most VW's have had these plastic sheets ripped out by stereo installers or confused mechanics, and their door cards have accordingly suffered.  I have tried a few different things over the years to get a plastic sheet to stay in place, but spray adhesives, contact cement and gorilla glue don't work.  Or they work too well.  Ultimately, I've just driven around without door cards while waiting for the answer to appear.  I found a posting on a website where a guy used that blue poster tack stuff (called BlueTac), and said it worked great.  I'll be trying it myself: a thin line of that sticky stuff all along the edge, taking care to avoid the door card mounting holes.  It occurred to me that this might be the solution I've been looking for with the belly pan too.

The belly pan, if you don't remember, is really a mechanical protection against rocks and such.  I've been trying to also use it as a splash-guard to keep the pedal electronics dry.  I'm going to try using the BlueTac solution with a sheet of plastic.  Figure, if I can protect a door card, I should be able to protect the electronics the same way: simple sheet of plastic held in-place with BlueTac.  I should also be able to cover the uppers, making the small sub-floor water-safe.  Neat.

That's it for today.  I bought some 3M-verson of BlueTac at Office Depot yesterday so I'll try the plastic thing this week.  Until then, here's another picture from the door card development effort.

Hapy New Year

Duh... Failed to put a title on this one.  I'll blame the post holi-daze. So, Hapy NewYear everyone.  I have spent a few hours playing with the bus, and I'll cover that first.  Otherwise, its been a week with the boys, and I'll touch on some of our adventures as well.

Slider Window Install

window in
color sanded paint looks shiny, eh?

The week started with getting the jalousie (jealous) window installed into the sliding door.  For all the other windows, there is a rubber seal that you really have to work onto the glass.  Then, you use the rope trick to get the seal-rimmed glass into the hole and sealed.  The jalousie window is different.  It is held in with a bunch of screws, and the rubber seal doesn't go over any lip in the door.  I tried to seat the window, but it wouldn't.  Maybe it was the new paint gripping the rubber.  I wasn't sure, so I color sanded the new white with very very fine sand paper.  Even then, and after cleaning the powder dust with cleanser the window wouldn't go in.  Finally, I ran a bead of KY jelly along the edge of the hole in the door.  This removed the friction problem, and I was able to force the window into place.  It didn't go easily; in fact, I needed to lightly smack the rear-end with a rubber mallet.  Once in-place, the window was simply screwed down.  Word of caution: do not use lubricant when installing a window that is not a-fixed with screws or bolts, otherwise it will not hold under pressure (read: collision).

Fixing a Hole Where the Rain Gets In

tools for patching a hole

In the 1972 Westy, there was originally a sink / ice box behind the front passenger seat.  This unit requires 2 drains: one for the sink and one for the melting ice from the ice box.  The drains route through a hole in the floor.  Well, 2 holes if you consider the hole in the floor and then another below it in a belly pan.  The sink / ice box units came with rubber seals to keep road moisture from coming up and in.  When I removed the old unit, I didn't address the hole that was left behind.  Years ago, when I bought the 1979 Westy interior, I installed the kitchenette / sink-hob down to the pair of holes in the floor.  Now that I no longer have the 1979 kitchen, I no longer need the corresponding holes in the floor.

To fix a hole in a place where it really can't be seen, its much easier than "real" bodywork.  I got some aluminum sheets for the install of the radiator unit, and I had a bunch left over.  I cut a small square and bent it to fit the contour of the belly pan (see picture, there's a rectangular bump-out over a flat-file).  I drilled 3 (1/8") holes on each side and then a-fixed the patch with rivets.  I'll shoot the patch with under-body rubber stuff so it seals tight.  Later, I'll put something in the body cavity to reduce road noise.  We know we want whatever I put in there to be closed-cell, so any moisture that could get in doesn't get absorbed.  I have a roll of that foil insulation I could use, but I don't think it is very effective at absorbing noise.... at least not as effectively as it insulated temperature.  I may put some down on the bottom anyway.  Once I figure that out, I'll patch the hole in the floor.  While I think about it, I'll patch the floor in the belly pan from the original ice box / sink unit.

Holidaze
It's been an interesting holiday season, switching from no kids to a house full of them and, soon, back again.  Boo and I hosted my extended family holiday event and laid-low on the actual Christmas eve and day.  For NewYearsEve, we took 6 kids up to SkiBowl for Cosmic Tubing.  The Tubing was fun, and SkiBowl put on a great time even with hardly any snow.  The resort is effectively closed pending snow, and the others aren't much further along.  Without some fresh snow, they will have to start shutting down lifts too.  We hit Timberline on the 27th (our anniversary), and the snow was pounded flat with a little powder on top.  That was a week ago, and they haven't gotten any freshies since.  I don't think I'll go back until something comes from the sky.  Hopefully, that'll be very very soon.

That's it for now.  Thanks for following along.

Weather Whether Whatever

Yep, its been a month.  I really don't know where the time goes.  When I look at my calendar for that past month, its been all over the place, so I can't point to one thing as my time killer.  I think its simply working too much.  I have had some time playing with the bus.  Boo and I hit the mountain for the first time yesterday, so I'll hit both of those today.

Whether Weather
When I first pulled the electronics together for the bus, I positioned the throttle unit (resistor pack that sends desired speed to computer) under the floor.  This area is protected by a square-ish pan with a couple of silver-dollar-sized machined holes that is supposed to be held on with 6 6mm bolts.  My bus being 40 years old, and having had multiple owners clowning on it, those bolt holes are not dependable.  For example, when I drove to the Futhur show I could hear the pan rattling in the wind.  Yikes.  Now, add the incessant rain we experience in the Pacific NorthWest and the sensitive electronics contained within.  Clearly, the bus was not ready for Fall, Winter and Spring.
First, I closed the machined holes with noise-reduction material.  This reduced the ambient noise as well. On top of that, I glued-in thin closed cell insulation for more noise containment.  I then ran 3/8" window insulation along the lip of the pan.  These 2 efforts solved the water problem, but I still had to get the pan attached to the bus such that the insulation would compress.  Since the bolts were rattling around the holes, I went to Home Despot and bought a handful of every bolt size from 6M to 8M in both metric and US sizes.  None of them worked.  So, I switched it up to thick (size 16) sheet metal screws, and sent one through the front-center and one through the rear-center.  The pan sealed right down and compressed the insulation.  Nice.  I tested the edges with a thin screwdriver, and I was unable to press past the insulation.  Problem seemingly solved.

I apologize for my lack of pictures.  The belly pan work was performed without the benefit of adequate light, so there were limited opportunities for taking pictures then either.  It looks like the drizzle has finally ended, so I'm going to head outside and address the turbo outlet that seems to loosen almost every time I drive the bus.  Once that's done, I just need to solve for the rear cabinet and protecting the electronics hidden underneath it.  Then, the bus will be ready for taking the family to the mountain regardless of the weather.

Sister Hood
If you've read this blog long enough to have read entries from last Winter, you're already pretty well aware of my love of snow.  Season lift tickets went on sale a few weeks ago, and I outfitted the family with passes.  Of course, the kids keep growing, so 5 out of 6 of us got new boots (even me; mine were shot), and we spent last weekend at Next Adventure getting extra snow pants, a jacket or 2, etc.  As I write this, I'm starting to figure out where my month went... anyway, Boo and I took a test-flight to Timberline yesterday in my Jetta (bus may go next time).  T-line always has the glacier to slide on.  They call it the Palmer Snow Field; I call it the Palmer Ice Sheet, but either there was snow on Thursday, and it hadn't warmed above freezing since.  As we drove through Government Camp, all the trees had a light snow-dusting on them.  SkiBowl has a couple of inches and even Summit has some.
The road to Timberline was snow covered, but sanded.  We realized our chains were still in storage, so the slight drifts we experienced had us a little on edge.  Still, we made it to the parking lot unscathed.  It was cold.  I mean cold cold.  Almost 0*F cold.  And a wind.  Take the cold and the wind, add that you're suspended in a chair 30' above the ground (and above the tree-line) and finally add that this was out test-run and we both inevitably forgot something.  We couldn't stay very long.  We got 2 runs in and called it a successful test.

That's it for today.  I hope to have the bus winter-ready by ThxGiving so we can take the bus to Timberline for White Friday.  It would really make my season if I could bring my 2 favorite things together.

it moves, its loud, but it moves!

Progress, progress. With an appointment at Meineke to build out an exhaust system set for today, I had a little extra motivation. Knowing everything was "good" according to my trusted mechanic friend, Justin, I moved quickly and confidently. I'll hit the highlights today, though there will definitely be more tomorrow.

Battery
Last night, I stopped at Batteries Plus and bought a replacement battery. With the instant discount and the mail-in rebate, it'll cost around $65 for a Group 40 (or is it 48?) Rayovac battery. I hadn't heard of Rayovak batteries since the old "I dare you to knock this battery off my shoulder" advertising. Apparently, they're deep into automotive batteries now. Anyway, I called them yesterday morning, and verified they had one, I picked it up and installed it last night after the kids were fed. I fired up the engine, grabbed T and backed the bus out of his hiding place into the driveway. There was much rejoicing.

Test Drive
T hopped into the passenger seat, and we tried to take a little spin around the neighborhood. We noticed a few things. First, an un-mufflered diesel engine is still really bloddy loud even if there is a turbo absorbing some of the noise. Second, while the engine was cold, the bus shook like a mother. After about 30 seconds it settled down. The clutch made all kinds of noise, and finding the gears was a challenge. I think I have some shifter adjusting I need to do. Reverse is easy to find, but I can't find first, so there's something batty happening there. Regardless, we drove around our little circle and around the neighbors little circle (cul-de-sac's) and pulled into the driveway. Our little test was over, but it totally passed.

Belly Pan, Clutch Cable Tightening
Before I could drive it to the muffler shop, though I had a couple of things I needed to do. First, I had to put the kids to bed, feed the animals, etc. Next, the belly pan that lives under the pedals needed to be re-installed. This keeps the weather from getting in there, which is especially important with the placement of the brake switch and the accelerator pedal switch. With the wet weather we've been having, we wouldn't want a puddle-splash to fritz the switches. I couldn't find the original bolts, but I found a handful of stainless 10mm bolts that fit. Last, the clutch cable needed adjusting. Now, the cable itself was relatively new before the project started, so it probably isn't fully warn-in. The clutch and pressure plate are brand new, so they will take some seasoning too. I expect to be performing some level of cable adjustment for the next few months accordingly. It had gotten to be about 9:30, so I called it good.

Drive to Meineke
My appointment was at 7:30, T needed to leave for school at 7 and C needed to leave for school at 8:45 (with a parent wake-up at 8). I am the only adult in the house, and I hadn't a ride home from the muffler shop. So, I woke before 6, with a funny plan for getting everything to align. First, I grabbed one of the kid's bikes and tossed it into the bus. I like bus-traveling with a bike anyway - its like a lifeboat. In case of trouble, you can pedal to a parts store from a roadside breakdown much faster and farther than on foot. Anyway, I pulled out of the driveway, and drove to the shop, using 2nd and 3rd gears all the way. Without the benefit of a tachometer, and not being familiar with the sound of an un-mufflered diesel engine, it wasn't easy guestimating the shift points. I relied on some common sense, though, figuring my shifts should come earlier than in the old pancake engine, and knowing that the accelerator only went to 78% meant I couldn't really get the RPM's into redline.
I arrived at Meineke as the defroster was starting to produce some warmth. I topped off the brake fluid (remember, I had it open to change the rubber lines earlier), pulled the bike out and rode home. I arrived home by 6:35, so I had time to prep for the day. T ended up staying home from school sick with that phflemmy coff thing that's gonig around, but I dashed back to the muffler shop to hand off the keys and talk about the project with the manager. "I want it quiet," I said. He accepted the keys nad I drove home to get C up for school. Again, I was ahead of schedule, and could enjoy some coffee before wrestling him out of bed. He got ready, ate and split for school (taking the lunch I made for him ) and I hit the road for work. I've spoken to Meineke from work, and the exhaust is done, with a lifetime warranty. Sweet. I'll drive it home, and post an update in the next couple of days about how it ran, sounded, etc.

It is hard to believe I'm actually at this point. There have been a couple of wrenchers without whom this would not have been possible. Hal and Justin, your assistance has been immeasurable and so, so greatly appreciated. I want both of you to sign the partition behind the passenger seat that's exposed to the main open area so your names will forever be connected with what we've done. There is time tomorrow to talk about what the next steps are, etc. For today, we smile. And nod. And bask in the gravity of the achievement we accomplished. Today, we have a 1972 VW camperbus getting pushed down the road by a 1998 NewBeetle 1.9 liter TDI engine.
