This is the 3rd or 4th one I've built over the years (the others being solid core doors on 2x4s). This is based largely on the "Bob Key" school of workbench building (i.e., all laminated pine). It is quite stable, but I don't know how the pine top surface will hold up. Also don't know if I'll like the tool tray or not. I'm debating adding more drawers underneath. In any event, it gave me an appreciation for building one in all maple.
