We have four 1100s, each with 2 Tormach 5" CNC Vises (total of 8). During a move and building renovation, we somehow lost 6 of the vise handles. So I thought "no problem" -- let's get some sockets and make speed handles. But I'm now learning the hex drive on that vise measures 0.570-0.571". 9/16" is 0.562" -- I've tried numerous sockets and only rarely is one oversize enough to (barely) go on one vise (then I tried ordering more of that socket, but the others didn't fit at all). 15mm is 0.590" and pretty sloppy.
Has anyone found another good way to drive the hex on this vise? Or know why they chose 0.570"?
All tips appreciated.
