Hi everyone, this is my first time building with both brazing and building a frame. I got a little instruction on brazing from a colleague who is a metal sculptor, and have been working from instructions from Marc-Andre Chimonas' book. So far I have the main triangle and chain stays brazed together. I'm using Columbus cro-moly and lugs, with 56% silver.
Here is where I could use some advice: In brazing the chain stays to the bottom bracket, I used too much silver and some of it pooled as lumps in the bottom bracket. It isn't a lot, but it is enough that it messes up the threads.
How should I deal with this? Should I grind it out? (Doing so would still leave me with plenty of threaded bottom bracket.) Or should I re-flux everything, apply some heat and try to draw it back down through the lugs to the outside? Or is there another way of dealing with it?
Thanks for your help with this. However it turns out, I'm having a blast.
Oh, and here is my blog, where I'm posting about the frame build:
