I seen a post on here a while back about making a work bench. I can't seem to find it now.What dimensions would be the best, or general rule of thumb? I don't need a lot of space just enough to chip away on a gun or two, make a horn or three and craft items and the like. What would you guys recommend for dimensions. Btw, I'm making the bench out of 2x4s simply because I have a ton of them laying around in my barn.
