Hi Tony,
These are new to me. Had a look on your website at them and can't work out how they work. Could you explain more?
Thanks,
David

Hey David,
There are 4 threaded holes in the upper bar and 4 threaded holes in the lower bar.  The lower bar is stationary and the upper bar swivels in the center so it will accommodate almost any size or shape of rock. You can also move the upper bar up or down as needed for different sizes.
It comes with 4 short screws and 4 long screws, you can use any combination of short or long screws and holes to find the optimum place to grip your rock. The screws have tapered heads on them so the edge of the screw bites into the stone.  When you have your stone ready to clamp you tighten down the nut on the rod closest to the stone until it snug, then you tighten up the nut on the rod farthest from the stone to create a pinch point.
The long screws work really well for cutting thunderggs in half and such, the short screws work really well for cutting butt cuts or the left over rock that you have after you take the chunk out of the vise.
There is enough sticking into the vise that you have a solid clamp, no more shimming.
Saves wait time for gluing as you don't have to wait for the glue to dry or worry about getting the last slab off the board, just loosen up a nut and the last one falls out.

Hope that helps.
Have a great day.........Tony
