Building a Shop - Steel Building Erected

First, my apologies for how infrequent my posts have been. The team I work on lost a team member to a promotion and the replacement has not been very successful. As a result, I have been doing the job of 2 people since the start of the year. This removed pretty much all of my slack time at work so lots of things have fallen by the wayside. Take, for example, Hapy, the 1972 VW Camperbus sitting in my driveway. The transaxle is still out, the engine is still on the ground and he has been that way for weeks. Anyway, this is where we are.

 

Oregon Carports

I will start with a call out to the fine folks who I worked with to get the building in the first place. From start-to finish, everyone connected with Oregon Carports and their parent company US Steel Buildings were great to work with. All communications were prompt, email did not sit unanswered for more than a couple of hours and honestly they spent more time waiting for me than I did for them. We arranged build-day around their other jobs, but the crew arrived within 15 minutes of our intended start time (early afternoon 15-July) even though they were driving from California. A 3 person crew arrived in a crew cab truck hauling a long trailer. They backed into the lane-way along the eastern fence and immediately got after it.

 

We had our fair share of hot days this Summer and this stretch of days was no exception. By 5PM it was over 100*F (38*C), but they were not relenting. I supplied them with ice and water from the fridge and encouraged them to not push too hard. They pushed hard anyway. They left around 7PM and were back the following morning by 7AM. They pushed through and completed the building by dark on the 16th. They did not want to spend another night at a hotel in Oregon and instead pushed towards home when they were done.

In transparency, we did a complete walk-through and before I could spot things, the job lead was pointing things out to his crew to resolve. We had originally designed the building to have a person-door on the front, but when they were doing the work I didn't like the design. So, after a quick call with Oregon Carports, the door was removed, my invoice adjusted and we moved on. Very easy.

 

Rain Water Management

With the building in place, my next challenge was around managing storm water when the rains inevitably return. I had received a coupon for those gutters you don't need to clean, so I had them come over and sell me. To my surprise, they could not design a gutter system that would work. It turns out that the design of the building, or should I say the design of the steel framing of the building does not leave anything near the roof line to attach a gutter that could have any kind of warranty. Sure, they could slap some gutters up there, but if ice forms, or if there is a heavy downpour filling the gutters, there was not enough strength behind the soffits to support and the gutters would fail... and then fall. So.. I needed a new plan.

 

Building Final Inspection

While musing over the gutters, I thought we were ready to have a final inspection and be done with the county. I was mistaken. I scheduled the inspection and while the building construction passed, he could not pass the job as final. The building did not have any doors, and had large openings where they would eventually go. I explained that we plan to have doors, but everything is so expensive lately, those plans are on hold for a while. He indicated that the building needs doors and the people door on the north face will need a landing or step since the building was a little over 7 inches above grade at that point. He assured me that once the doors were on, final inspection would be a quick confirmation. Meanwhile, the permit stays active and open without penalty. The reasoning around the doors is that the building has certain specs around wind resistance and those numbers do not hold up when it lacks doors / is not sealed. The inspector had no interest in gutters. They were never on the plan, and the plan was approved without them, so that tracks. It just seemed odd.

  

Trenching

I figured that if I could not catch the rain at the roof's edge with a gutter system, I would dig trenches along the eastern and western sides of the building, and install french drains to manage it. That sentence took about 15 seconds to type and the better part of 3 weeks to execute. I started with taking lots of measurements to determine how deep I would need to go, and made 2 sets of plans. Plan 1 was to route the water from the eastern and western edges back to the rear of the building and then into a storm outflow I had dug out when the foundation was done. This plan would have required the southwest corner to be dug down nearly 2 feet to account for the ground pitching from southwest to northeast.

installing pipe

Plan 2 was to dig the trenches towards the front of the building, cut across the future vehicle egress and into an abandoned well on the property about 40 feet away from the northern edge of the building. While this plan involved more linear feet of trench and more pipe, the trenches would not need to be nearly as deep, digging down no more than 9 inches from end to end. I decided plan 2 made more sense, and proceeded to trench 30 feet along each side, 24 feet across the northern edge and then another 40 feet from the north east corner diagonally across the future driveway to the abandoned well.

 

Drain Pipe 

Into these trenches, I laid french drainpipe wrapped with filter sock. The trenches along the sides of the building got the less expensive flexible pipe. These pipes cannot withstand much weight, but being right along the building, I would not expect them to. Across the northern front of the building and across the driveway, I used the hard pipe which is designed to handle considerably more weight. Still, these pipes were 6 inches below grade, so weight would be somewhat distributed. The last 20 feet between the driveway and the well, I used flexible standard pipe (not french drain) as this passed through a garden area. Practically all of the rest of the pipe was french drain wrapped in filter sock. I added a drain clean out in the northeast corner.

 

Grading and Graveling

With the pipe down, I could see that there were some spots along the building where water could slip past the pipe and run away from the drainage system. To remedy, I used fill dirt from the foundation dig to build up the downhill areas from the drain pipes. As I layered in silty clay, I watered it in so it would not wash away during the first rain (it didn't). Satisfied, I ordered 4 yards of 3/4=1-1/4 drainage gravel delivered into the laneway, about 75 feet from the building. With a shovel and a wheelbarrow, I filled the building-adjacent trenches and the small valleys I dug along the trenches, creating a gravel stripe about half a meter wide.

 

One Small Step

With the trenches done and filled in at least as far as the front of the building, I started after the step or landing that the inspector required. I looked up the code and the step needed to be at least 1 meter square (width of the door, square). I decided to make it bigger, running from the corner of the building to the edge of where the driveway egress would start, and then make it the required 3 feet deep. I used some outdoor grade 1 by 8 we had lying around with a couple of 2 by 4's for corner re-enforcement and drove it into the ground. After checking level and stuffing some rocks underneath to hold it level, I put a layer of melon-sized rock on the bottom and filled it with some of the drainage gravel I had.

This is getting long, so I'll stop here. I will say that the work on shop/barn/building/garage has been my sole focus this summer. So, almost no car work has happened at all after the grand dismantling of Hapy over Independence Day weekend. I did spend a different weekend replacing the oil pan in my niece's Jetta TDI after she drove over a tree stump, but that's just being an uncle. It took a weekend because I had to go get the car from the middle of the woods where it was left, drained of oil, so yeah, it actually took a weekend. I will go into more detail on Hapy's flywheel replacement effort once it reaches a Hapy conclusion.

 

Thanks, as always, for following along. 

Now Water-COOLed

Before I begin, our family lost a brother over the weekend (14 September). Travis was taken from us too soon, but he left doing what he loved most, riding his Harley on a beautiful early autumn afternoon. To meet him was to know him, and to know him was to love him. You will be greatly missed, brother. On to today's post...

The cooling system for Hapy's new engine has been a journey. Looking back on multiple years of efforts to get Hapy to be genuinely water-cooled, today's post covers what may be the last thing I needed to do. I have lots of links referencing pretty much all of the things I've done, but I probably missed a few at the beginning of the project because many of those early posts covered multiple project aspects.

Initial Cooling System
Recall when I started this project, I sourced a radiator off craigslist for $30 (See TDI - Day 2). At the time, I was even offered the air-conditioning condenser, and it had the original fans. I passed on the air-conditioning condenser, which he subsequently sold, and I removed the fans. I added 2 flex-cool fans and wrapped the radiator with an aluminum frame (See bracketing the radiator and rad brackets continue) and put sides on it (See Radiator shrouded) to reduce the amount of air allowed to slip back around from the rad exhaust back into the rad intake. This sort of worked, though I always had my eye on the temperature. Along the way, I removed a bunch of extra wiring from the original harness that was part of the air conditioning circuit, and added a switch to the dash for turning the fans on.

Troubles

Then the leaks started. I spent many hours trying to solve outlet flange leaks (See Reality Strikes, for example). Ultimately, I learned that the plastic parts were designed to fail first, so more expensive parts didn't fail when the engine got too hot and the coolant expanded faster than the expansion tank could handle. Still, replacing that outlet flange and getting the coolant temperature sensor to seat properly are two of the most patience-testing things I've done on this conversion. Having these components by the fuel tank makes the reach and visibility particularly difficult.

Still, with the system seemingly in-tact, the engine temperature would still climb and not come back down easily. As the miles and years passed, the engine would heat up faster and cool down slower. We had a super-long return from 4Peaks in 2017 (See 4Peaks 2017 - Road Report), and had our first vagabonding experience when we were unable to make it to Frog Lake due to an overheat, and big coolant loss (See Almost Frog Lake Part 1 and Part 2). The whole time, Boo was incredibly supportive, and heroically kept my spirits up. My last, most tragic failure was when I added the wrong kind of coolant. That amplified the problems, and ultimately led to the troubled drive to Newberry this Summer (See Newberry 2019 - Getting There).

Resolution Path
I promised Hapy that I would start fixing the cooling system when we were on the side of the US-26 outside Rhododendron, unable to make it to Frog Lake. So, that next Spring, I replaced the old Jetta radiator with a Mishimoto all-aluminum radiator (See Back to the Bus: Rad Swap Part 1 and Part 2). Things were not that much better on the way to 4Peaks in 2018 (See 4Peaks 2018 - Road Report), but with the ignition fire on the way home, it quickly moved to the back burner. I removed the wiring for the heater fan controls when I did the ignition replacement, believing it was causing large load spikes. While that didn't really change the cooling system, its a change worth documenting. By the time the ignition was done, festival season was over. But before I covered Hapy for the winter, I replacing the fans with a real dual-fan shroud (See Cowling the Hapy Radiator). I thought this was the final solve. The drive to 4Peaks seemed fairly good (See 4Peaks 2019 - Road Report), with temperature spiking at 196*, but the drive home was again spent watching the temperature gauge. We peaked at 205*, but the alternate route through the farm country allowed us to keep our speed (and therefore temperatures) down. The drive to Newberry, though, was enough for me to know that I had not solved the problem, and I really needed to fix it right if I was going to truly enjoy driving distances with Hapy.

Last Solve

In my last post, I described the issues with the fuel I bought in Oakridge (See Green Diesel isn't BioDiesel). That bad fuel held my speed so low, I didn't have temperature issues the rest of the way home. I knew they still lurked, so after the fuel system was drained, new filter system installed and new fuel added, I shifted back to my nemesis: the cooling system. I started with a basic drain and water-flush. Then, I removed the thermostat and filled with water, ran the engine, and drained. I did this a couple of times. Then, I went nuclear and did a chemical flush with Thoroflush. The Prestone radiator flush is weak tea compared to this stuff.

The directions are hard to find on the internet, but it's fairly clear:
Remove 1 gallon of coolant from your system
Mix one gallon of water with the right amount of Thoroflush mix for your application
Add mixture to cooling system
Get engine up to temperature (to open thermostat) and run for 10-15 minutes. DO NOT RUN LONGER THAN 15 MINUTES
Drain and flush with water until drainage is clear (no pink from chemicals)

Seems fairly straightforward. But, I pulled my thermostat, so how long do I need to run it? I was unable to find any direction for this case. I concluded that since my engine was fairly warm (upper 160's), if I added the mixture and ran it for less than 15 minutes, I would do no harm, but might not get maximum benefits. So, that's what I did. I used the water from the 2nd rinse-flush and added the mixture to that, ran the engine for just shy of 15 minutes, drained, flushed, and flushed again. After flushing everything out, I re-installed the thermostat with a new housing and O-ring. I determined that the old housing was slightly warped (possibly from the flushing efforts), and found that removing the hose from the thermostat housing makes re-install 100x easier. I filled with G40 and distilled water, clearing the bleeders so there were no air pockets trapped in the system.

Testing and Proving

I wanted to demonstrate that this was the fix. So, I drove around town like a total dick: jack-rabbit starts, rapid accelerations... basically zooming around West Beaverton pushing the bus as hard as I could for a good 15 or 20 minutes. It wasn't until I pulled over onto our quiet street that the temperature raised above 185*F (to 188*F), and even then it was only for a second before it dropped back down to 185*F. The real test came later in the week when we drove to Honeyman State Park, up to Newport, through Lincoln City and home again. I'll post on that trip later, but I'll summarize the coolant test with a simple number: 194. 194*F was the highest the temperature ever got the entire 300+ mile road trip, including climbing the coast range and driving in slow, heavy traffic. At no time did I need to pull over because of the temperature. I did not drive especially gingerly either.

There is a hill climb on 99W between Newberg and Sherwood. Every time we take the back road alternate route, we drive up this hill as our last big pull. Accordingly, it is a consistent gauge for how Hapy is doing. When I drove this hill after Newberry, I barely kept the temperature under 203*F, driving with the flashers on in 2nd gear (25mph* tops). This time, Hapy's temp peaked at 194*F running at the speed of traffic (55mph*) in 4th. In both cases, this was at the end of a multi-hour daytime summer-heat drive. This feels like strong evidence the cooling issues have been solved.

That's it for today's saga. Sorry there weren't any real pictures, there really wasn't much to take a picture of, except, maybe, a picture of the cooling system map. That reminds me, I never did document system-by-system how the conversion was done. Hmm.. maybe I should dust off that documentation effort over the winter. Anyway, thanks, as always, for following along.
