Go a search on "weekend workbench" plans. I built this bench out of
kiln dried 2x4's from Home Depot. The legs are laminated 2x4 done in a
way that looks like half lap joints. The railes are attached to the
ends via nuts/bolts in pocket holes so you can diassemble if so choose.


The plans call for a solid core door which is what I used. I added oak
trim to the perimeter and drilled 3/4" dog holes around the perimeter.
Plans also call for drawers but I needed the extra shelf space and did
not do the drawers. You could put any top you wanted included a
laminated maple I suppose.

I coated with a couple coats of poly. It actually looks and performs
quite well.
