Thanks Mike. I added the drawer too. The original metal base was just that. When I got it, the top and any drawers that may have originally been part of it were long gone. My aunt had a marble slab sitting on it and used it a a plant stand for years - consequently the marble slab is now my sharpening center top!
I could not figure out how to attach the shelf to the base. So instead, I made a hanging drawer. The drawer runners are on top of the drawer sides and slide in grooved slides underneath the table top - just hoping I allowed enough room for top expansion on this slides.
