doesn't like 70S-2 0r 70S-6 filler wire all that much. The new 1020 DOM
is fine but the old stuff is like snap, crackle and pop!
But good ole 309 stainless is just fine.
Hey guys, been doing a frame for a friend and found that the old tubing
doesn't like 70S-2 0r 70S-6 filler wire all that much. The new 1020 DOM
is fine but the old stuff is like snap, crackle and pop!
But good ole 309 stainless is just fine.

I think he means " old school " - oxy / acetylene conventional brazing like they always used to build bike frames by hand - before Japanese robots learned to weld ! it gives good results in terms of looks / strength & spreading the load over a good area of tube so it's less likely to fatigue crack - often the old ways are still best !
