I have a 'wet' bandsaw that uses diamond blades, i'm told when they
break, they can be silver soldered. The charge is about $30 to have
ONE blade repaired.... my husband says he can silver solder. Is there
a special technique for silver soldering a diamond blade? thanks .....

Run a web search for " Bandsaw Blade Welding Jig ". I've seen jigs and plans
to make jigs for sale for welding blades. RM~
