I looked at the 16-in Orange vise a few years ago, mocked it and the Tormach up in CAD, and came to the conclusion that using the Orange vise would cost too much capacity in Y. There was talk of them making and selling a smaller vise but I lost track of progress in that area. Just checked and it looks like all their vises share the 4-in deep back (fixed) jaw. You might try contacting the owner (Sol?) and see if he has any suggestions. He seemed like a helpful guy in email.
