For those of you who have twin screw end vises or are just mechanically inclined, I have two questions-
1. Has anyone investigated adding sprockets and chain to link two standard acme lead screws to make a twin screw vise like the Lee Valley end vise? (how did it work?)
2. Other than leaving a bit more space below the table for the sprockets and if the Acme screws are long enough, is there any reason that you couldn't mount the sprockets on the ends of the lead screws that are under the table?
You would probably need a spreader bar with bearings so when you tensioned the chain (to remove backlash) you would not bend the the lead screws and cause them to bind against the mount.
Just thinking ahead to the day I finally get around to building my traditional WW bench.
