Hi, I'm receiving a new (actually old, but new to me, and not used a lot) Erba NJS track frame. My coach got it and a U-Haul of other pro-Keirin stuff from an ex-Japanese pro now situated in Detroit. He'd giving me the frame for practically free. The only problems are:
1.) For some reason, this racer drilled brake holes in the fork and rear stay bridge.
2.) During shipping, an axle put a small dent into the down tube.
My coach says that I could use silver and braze everything up with a propane otrch since I don't have access to an acetlyne torch.
So my questions are:
1.) Will silver and a propane torch be suitable?
2.) Will the fork and bridge be as structurally safe as before?
3.) When brazing the holes, should I put something behind the hole, or should I just plug it up by making the hole smaller and then filing?
