I have the new area for my shop expansion cleaned and is a blank canvas The first project for it is a proper wood working bench. The top will be 6' x 3' made from ash. I plan an end vice of some sort and a leg vice for the front. The top will have dog holes also. So my question is how thick to make the top? I have heard 1 1/4" minimum for dog holes, I have seen 3" thick tops, that seems overkill. So some where between 1 1/4" and 3"? I have had 2 1/4" thick in my mind. Am I thinking correctly or should it be a different thickness?
