I started off Friday feeling pretty confident that I could get this bike done in time for the VW show on Saturday. Basically, all I had left to do was assemble the bottom bracket, rebuild the wheel hubs, and install a chain.

I started off with the front wheel hub, which went well enough. I shot a video of it spinning in the fork after the rebuild, and a full minute later, it was still spinning almost as fast as it was at the start!

Next, I tackled the bottom bracket. I had to find a set of bearings, bearing cups, and races that would all work together. Finding the right races seemed easy enough, but finding a pair of matching bearings in usable condition required some work!

The 3 bearings up top all started off looking like the one on the bottom. I had to manually wire brush all the caked-on grease off the bearings to see what kind they even were, and then use a toothpick to pick out the gunk inside each of them. I then used my ultrasonic cleaner to take care of the rest. It was way more work than I expected, but I think it was worth it.

While I was testing out the bottom bracket pieces, I checked the alignment of the gears. I sadly found that my big 22-tooth sprocket I wanted to use was bent, and I wasn't sure how to fix it at the time.

I also found that the spacer I put inside the bottom bracket stuck the chainring out way too far to line up with anything.

That was just the beginning of the headaches with the bottom bracket. First, the bearings kept making a weird sound like they weren't moving right, even though all the balls spun fine in their cages in my hand. I tried different bearings, but still had the same issue. I figured the problem would go away when I added grease. Then I found the chainring wobbled a bit, but only sometimes. I figured I could straighten it out on final assembly. And then, when everything was greased, I couldn't get the races tight enough without wobbling or causing the crank to stop spinning! It was driving me nuts!

(You can see videos of the issues listed above on ratrodbikes.com.)

On a side note, in the middle of assembling the bottom bracket, my next door neighbor called, telling me to come over as he had something for me. He found these 4 bicycle inner tubes in his garage as he was cleaning it, and said I could have them. While there, I helped him move a few things around that would be difficult for him to get to himself, as he's at least as old as my grandma, if not older. We chatted for a bit too, which was fun. After being there for about an hour, we both got back to doing what we were before.

After the headache with the bottom bracket, I decided to switch gears and work on rebuilding the coaster brake.

I also decided to go with the 20-tooth sprocket on the right, instead of the bent 22-tooth sprocket on the left.
299476-BftD-CWC-klunker-final-assembly-16.jpg


After wiping everything off as best as I could with some shop towels, I ran everything through my ultrasonic cleaner for a couple cycles, hosed them off, and dried off everything using the air compressor.

Just so I'd get a better idea of how everything went together, I mocked up the parts outside the hub. It definitely helps.

Thankfully, reassembling the coaster brake hub was pretty straightforward. All that was left to do was troubleshoot the bottom bracket...

I wasn't sure it'd really fix the issues I was having with the bottom bracket, but since I was already using Schwinn bearings, I figured I should try Schwinn races with them. I found a set in good shape, and threw those on the crank.

It definitely seemed to help, as the chainrings now spun relatively straight and much quieter. (More videos of that and the coaster brake test here.)

One issue I never quite figured out though was why my chainring and sprocket never seemed to line up right. Whenever I placed the yard stick against either gear, it always went behind the other. The yard stick wasn't bent or anything, and I had the rear wheel centered in the frame as best as I could get it, so I don't know what the issue was. All I could think to do was just flip the sprocket out to hopefully line up with the chainring better.

Adjusting the bottom bracket was a bit tricky, as I had to get the nut tight without tightening the race any further. On top of that, if I got everything too tight, the crank would not spin freely and snag in a spot. Too loose, and the crank would wobble uncomfortably. I zip-tied the crank arm to the chain stay to help hold it in place as I worked. It took a few tries, but I found a good enough balance to make it all work.

I grabbed a chain, shortened it to length, installed it, and tested out the pedal action and coaster brake. Perfect.

I stuck a bolt inside the hole for either a chain guard mount or grease nipple, then threw on a kickstand.

Once that was done, I rolled the bike out of the garage at 11:42pm and spun it around the driveway! At that point, I decided I was not only going to the VW show regardless of the weather, and I was bringing my klunkers too! I started getting everything I would need together for the show, and not a moment too soon, as it started raining just after midnight.

I got to the VW show at about 10am the following morning, and thankfully, their was no rain the whole time I was there! I bought both the CWC klunker as well as my klunker Belle to ride around at the park. (I never rode Belle around, as the bicycle events didn't happen.)

I had also swapped out the seat on the CWC as the other one felt a little too small, and it felt weird riding it. Turns out the problem might've just been that the seat clamp wasn't tightened enough. I also learned during the show that I need a longer kickstand.

While the weather definitely had an impact on attendance, it was still a good turnout at the show yesterday! Even better, my CWC klunker was doing great! I actually spent a good chunk of the time riding it through the grass and mud, and it just kept going like it was no big deal! The coaster brake works better than any other I've built so far, and the ride position feels right! And with mud on its tires, it looked even better!

I didn't shoot as many photos at this show as I did last year, but here are a few highlights.

I'll have to get some better photos later, but here's how the CWC looked after I got it home from the show.

I am genuinely happy with how this klunker turned out! Not only did I finish yet another bike build using just the parts I had laying around, but I managed to set a new personal record by getting it done in just 4 days, from first mockup to final assembly! I can't wait for the weather to dry up (seriously, dry up already!) so I can take this klunker out to my favorite gravel trail and ride it the way it's meant to be ridden!
