Vise holddowns

[Crusty]

It will be much like your clamps but without the screw in the center because the chuck on the rotary table won't allow access for tightening in that location. The lip on the clamp inserts into a slot in the rotary head and the block is sized to pull it down to the table (or maybe I'll use shims underneath to get it pulled down just right).

I made a low profile milling vise that's much like it so it shouldn't be too difficult.
