Yes, the BB has following dimensions: (Ceeway #W100) 57.4x64.8x7°. I needed 57.75*x 66.8* x7*. I only needed 2* increase between ST/CS. There was almost that much slop in the chainstay sockets. The bar was nice because it provided a bit of an anvil inside the socket and it stretched the sockets but kept the rounded shape very nicely. The harder part is tightening up the base of the socket. I have some 3/8" bars of brass and aluminum I use to blacksmith it all into place.

Speaking of, I was driving through the neighborhood a week or so back and a guy near us had his garage door open. He had what appeared to be a blacksmith shop in the garage with a fire pit and anvil. I've wanted to stop in ever since. We're in a pretty urban setting so, it's a bit odd to see a big fire burning in someone's garage! I'm sure my neighbors think the same.
