The pull apart is a second and the rejoining is the third. If the first was badly done (and the crack/lug separation from the HT/DT suggests such) then the repair has an even higher need for care.
Given the question about which torch is a good choice makes me think you have no experience in brazing. Is this correct? If so then I don't suggest you try this repair until you've done a fair amount of torch work and it's proven to be good work by time and miles.
Sorry to be the one to have a strong opinion. Just trying to have you avoid a weak frame after the repair. Andy
Oh I fully agree! I would not attempt anything before I thought I had the necessary skills. There is a frame building course I've been strongly considering taking here in BC (taught by Paul Brodie), if not that, I plan on learning at some point. It's a long term project, I would hate to needlessly destroy a beautiful frame...and would be rewarding be able fix it one day. I appreciate all the cautionary info just the same! point well taken. Thanks!
