repairing reynolds 531 tubing
emerbmx:
Would anyone have any ideas or tips on repairing 531 tubing cracks?
I have frame with cracked headtube, cracked along the weld, then continues a bit and reaches the top of the headtube.
cheers

any brazing/ tig welding should do the trick, or oxy - acetylene, i take it the frame is os? if so u just need it to be cosmetic, a normal steel welding wire will work, no need to buy special 531 rods, hope this helps.
emerbmx:
yes its an old 83 quad.
cheers - that helps-
someone tried to weld it before and they dam near almost blew a hole through it.
