I'm on the fence as to whether or not to put levelers on my 'next' bench. I'll gain a minimum of 1/2" if I add them and be focusing the weight on a smaller spot than if used without.
I'm of the opinion that if I position the bench I probably won't move it for a very long time. Bench weighs about 300lbs. I have a rolling worktable that is used for that purpose. Just wondering what others have found.
