I’ve seen some videos online where people make/fix their own bandsaw blades by silver soldering/brazing.
So I went ahead and ordered some silver solder (not the tin junk from the hw store, but the real, expensive silver-bearing stuff), and some of the 601 flux the guys from the videos seem to like.
I cut the scarf, sand it, flux it up, apply solder, allow to cool… and the blade snaps like a twig.
So I try again, getting the blade red hot this time and backing off slowly when done to keep the metal soft…
It seems to flow together fine when I do it. In fact, after it breaks, I see even solder inside the joint, but for some reason it just won’t hold! Any idea what I’m doing wrong!??
