Bandsaw silver soldering fixture

Propane is probably not hot enough and you need to be careful that you don't take the temper out of a large section of the blade with a large flame. MAPP gas would probably work using on of those small torches with the small flame.

Propane is easily hot enough you're only silver brazing 2 short lengths of thin blade together, I've been doing it for years & I grind both ends together at the same time on my disk sander so they're the same angle &wet flux with a small piece of silver solder hammered thin on the anvil between the blades into my homemade jig & heat with my plumbers torch then cleanup on the thickness, the hardest part is getting cheap 100 ft coils from autojumbles, as there's not many about I buy cheap longer blades & cut 'em down, hope this helps.
