I'm finally getting around to building a workbench for my man/gun room(spare bedroom). I plan on bolting on a small vice for gun work eventually and some reloading equip. I'm going to put a shelf or two on the wall above it with a good light underneath it.

So far I've got it planned at 6' long 30" deep and roughly 38" high. The legs are sistered 2x4 and all other supports are 2x4 as well. The shelves are both 3/4 hardwood ply with supports and I think I'm going to use a couple 2x12s and a 2x6 with a sheet of 3/4 hardwood ply glued and screwed(countersunk) for the top.
