broken bandsaw blades

I made a very simple jig to hold the scarfed ends correctly aligned while brazing them. The jig took an hour or so to make (real simple stuff), and it takes only a minute or two to prepare the ends and make the joint.

I clamp the ends down to my welding table and TIG the ends back together, temper the weld with a torch, and flatten the weld on the belt sander. I've never had a repair fail.

Silver brazing makes a very strong joint and is easy to do with a propane torch and a simple jig. Scarf the ends at about 30° and clamp in alignment before brazing. I have made blades from bulk blade stock using this method for many years without problems.

Any difference between bimetal blades and plain carbon? I have a cheap blade welder and it welds plain carbon fine but so far I haven't had luck welding the more exotic bimetallic blades ..

I use a Airco 300 Squarewave tig welder and stainless steel filler.
