I made a welding table ages ago using import platens which use the 5/8" hole pattern on 2" centers with 4" side skirts.
I would love to mount a Sidekick vise to my setup, which looks like it might fit with minimal modification, but I also saw that there’s two options (FA75-SDV800 & FA75-SDV400). Can someone help me out with which option would be easier to modify for my table?
The holes on the Arcflat table are 1" from the edge on both the sides and top.
