I have a few questions. Did you braze a new brake bridge because it was neccesary for clearance, or because you thought the other one was ugly? It's not clear from the other thread. If you cut down the head tube, surely it should be easy to find a fork with enough steerer? I simply don't have the skills to braze on a steertube extension. Did the chainstays collapse because of the absence of the various bridges and braces?
I really like the idea of this bike, but I'm concerned that there might be too much surgery involved.
