Re: rock saws
Mix a small batch of portland cement without sand to a fairly soupy consistency.Them take a � gallon milk carton and begin to fill it with the stones to be slabbed. Put in one layer of the stones so that the cut will be across their smallest diameters them add enough cement to cover the stones and fill in the spaces between them.Add the next layer of stones, more cement, and so on, until the carton is full.Leave about 2 inches of plain cement on the top.This will permit the stones in the carton to be slabbed while still leaving a portion of the block to be gripped by the saw vise.Knead and agitate the carton until the cement fills all the spaces, and let it set for a day or two. Them peel the carton away from the cement block. The cement will be hard enough to hold the stones for slabbing after drying overnight.Do not save the blockstoo long before cuting,since they will begin to crumble.Even the smallest stones can be cut into slabs in this way, as long as the outer surfaces are rough.Usually the cement will break away easily from the cut slabs. If it does not, a little gentle pressure with a pair of pliers will do the trick.
