Where to mount the workbench vise

[joe milana]

My vise did have a pop up dog but I still put 3 dog holes in my front jaw piece. These align with three rows of dog holes on the bench leading away from each vise, front and end. Here's a shot of the center rows while the top was under construction:

Glen, Nice bench. How is the MDF holding up around the dog holes? I would think the holes would want to enlarge and swell around the holes over time.?!?!

I have my vice mounted to a 2' by 2' piece of plywood which I clamp to the workbench when and only-when I need it.
