Anyone make their own TSS?

[paulinkansas]

I'm renting a place to some Louisiana guys that are here for a short industrial job. One guy says he makes his own TSS shot. He does alot of work in big industrial plants. He gets the used tungsten rods from welders, since they no longer serve their purpose for tig welding. It's not pure tungsten, but an alloy. Melts it in a crucible and runs it through a dripper. He says it is about size 7.
