Re: [ATM] Material for Tool

Dave,

I suspect that you could make a 20 inch x2 inch tool with a 20 pound bag
although I'd have to do the math. 20 pounds is alot of dental stone! It
takes about three pounds for a seven inch tool. 4.25 for an eight inch tool.

The stuff is very dense, not too heavy though.
