Re: Foundry for melting metals

The experience I have with a serious coffee grinder is that you're not going to be melting what you really want in the backyard to make your burrs.
I bought an industrial disk coffee grinder with Turkish grind disks. Those disks are incredibly hard steel. They're about razor sharp, and have stayed that way despite grinding ferric sulfate with it for a project at work. That project didn't work out (next step was cryogenic grinding that crap, and that didn't work out either) so now I've got a really amazing coffee grinder if I ever want to grind coffee by the pallet. Nice consistent grind too, down to 8-10 microns. (the cryo grinder got me down below 4 micron particles with a bunch of sub micron dust... crazy)
That said, it would sure be nice to be able to cast something once in a while...
