The dropouts and chainstays are ready to be silver brazed. I mock them up with the bottom bracket at the designed length of 410mm. I didn't realize the fit into the dropout was a compound angle, more work than anticipated. Because I have to compress the seat and down tube angle, I will have the full frame in the fixture when I tack the front triangle. This way, I can insure the seat tube/chainstay angle won't be compromised.
