Jack,

That's the one. Put it on. Mine is a Taiwanese copy of the Record, but it works well. I too have generous, thick, wide chops front and rear, but lately I've been noticing I get some slipping, so I think I'm going to use some of the suede left over from my Moxon vise to line at least the front chop.

Regarding racking, yes, this vise will rack if you put a board on one side of it. This is easily handled by using a low-tech spacer! Just take a small sample of wood the same thickness, squeeze a small hand clamp around it, and set it into the other side of the vise. The clamp will keep the spacer from falling through the vise when you open it.
