Yes, the body will not work. I think that I will just throw this into
the muriatic acid bucket and will play with something else in the
tumbler.

done some small pieces of hot rolled and cold rolled with scale and rust
(just before we were throwing away the media so I didn't get screamed at
:-)), and it took off the rust but didn't really cut the scale. Our media
won't go into small holes, but smaller media cuts a lot slower. Those
flat
triangles would probably be better if you have small nooks and crannies.
Anyway, should work for the hardware but not the body and the moveable
jaw.

OK, I am sure that I will find some uses for it. Does tumbling ruin
threads
on bolts?


Have you considered Evaporust? Easy to use, safer than muriatic acid,
re-useable...
