Anyways I'm onto Shawna's....bike....actually I don't really know what kind of bike it is. That's sort of scary. I guess I've become partial to building mountain bikes or at least fillet brazed bikes. It'll be cool though. Some sort of randoneur/tourer with 650b wheels and lugs throughout with Paul's new racer brakes. It'll be crazy. It took a few renderings and I ended up changing it up again today and slackening the angles half a degree and lowering the BB. I think it'll work out well.
The request back in the east was more pics of what I'm doing and we just got a new internet connection up and running so we'll see if the uploads go a little more quickly. Here's a show and tell of today's work.
facing the head tube/top tube lug so a head tube extension sits flush
the lugs do not have an even face from the casting injection. the uneven color is where I started to face the down tube lug.
head tube/top tube lug and 20 mm extension. The extension is a piece of 1 3/8" x .058" chromoly
both the lug and the extension are faced for a seamless fit. when the frame is brazed I will sweat silver through the whole unit here and then clean up the finish with a file. (the extension is slightly smaller)
marking the top tube mitre at the seat tube. the head tube is already mitered. I mitre everything with hacksaw and files at this point so I do them one at a time to minimize any chance for error. These machined tubing blocks are invaluable to me. from goodtimes bicycles
tacked BB/seat tube. The discoloring is because I defluxed with a wire wheel instead of soaking. I'll be fillet brazing the bottom bracket joint and chainstays. This just seems to make more sense. Lugs are a very big design constraint (certain size sockets placed at certain angles) and tire clearance is not a place where I want constraints. Plus nice fillets here just look cool to me.
Mitering the downtube seat tube junction.
the first snow ride on the year on the General Lee. I had to disconnect the brakes so they didn't pack up with snow as bad. Enjoy y'all. See ya.
Hey thanks for the photos. The General Lee doesnt look right with snow on it. Hazard county never gets snow.... but what the hell. Now the firewood is right in there. Cooter was out there splittin it up. cant wait to see this bike a little further along. peace!ReplyDelete
