Everything should work now. I built a stand for it out of two pieces of 3//4" plate and 6" pipe and bolted it to the concrete. When I started screwing it onto the 3/4" plate, I found the bottom of the vise wasn't flat. So I had to machine it flat. This is a good, very strong vise, but be sure to check his flatness before attempting to screw it to a table, otherwise you could damage the cast iron it's made of.
