Bandsaw silver soldering fixture

I thought the jig should be made from wood so that the heat is not dissipated quickly.

I like to see the actual brazing.

Hi Ralph
I will do a video on silver soldering very soon and post. The temperature of the silver solder I use melts at 720-degree C so very hot and the wood could cause a fire. I hope this has answered your question and thank you for taking the time to view the post.

That would be most welcomed, a picture is worth a 1000 a movie millions.

This appears to be a simple fixture to make, so all I really need is likely some silver solder. I must ask though do you believe a propane torch could heat the band fast enough to do a silver solder joint properly? Also preferences for solder and flux would be appreciated.

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.
