   I salvaged some scrapped 95-5 Sn+Sb solder from the trash at work when they   
   rebuilt a set of heatsinks for temperature cycling GM ignition modules. It   
   can be cast into work holding fixtures in wooden molds without charring them   
   as lead casting does, so I made a vee block that can be drilled into. When   
   bent it makes the "tin cry".
