This is the little frame I used to practice doing a splatter paint job for Splat Rat. I've got the time and parts to enter this third bike in the ORBO.
This frame is NOS, rescued from the dump last year and has funny sizes to the cranks and headtube. It was destined to hang on the shop wall, but I took it with me to the bike shop last week hoping they might have old stock that would fit it, mainly the head tube. They said standard parts could be made to work.
It is slightly smaller than the standard 1" headset. I've had the crankset, an oddball cottered type with bearing cups like a one piece but smaller. I just honed out the bottom bracket with a grinder on my dremel and the cups hammered right in.
The shop owner told me to grind down the standard headset cups until they fit, and grind on the frame too until the cups fit. But that would make them way too thin, they are thin enough already. My solution was to cut a slice out of each cup to make them fit. It worked with some hammering to get them in, and the bearings still fit properly.
The shop also had a seat post that fit, 22.2 I think. So, this bike will work out after all. I asked if they had a cottered chainwheel, and they did, a 40 tooth ancient set. The plastic wrap looked 20 years old and was fused with the black paint. It's stuck to the metal. It'll get matching paint to the frame.
I've got 3 sets of 20" wheels to choose from for this build. If the 40 tooth chainwheel is too low a gear, I've got another one, 48 teeth that looks much better but has long crank arms. The 20" chrome forks I picked up just for fun because they looked good a few months ago will work fine. I got much farther along today than I thought I would.
