I've been reading the thread about ball mills. Last night, I was
watching NCIS. There in the lab was a ball mill in action. Looks like
it could be hand built. And what was it being used for? The lab tech
put fake gold coins along with a solution of I forget what into the
ball mill to show that the gold coins were only gold plate and were
worthless. Hey wait! Wasn't that just discussed on Clayart????
