I recently bought a new 15” floor drill press (Porter Cable PCB660DP), and want to build an expanded wood table/cabinet to hang from the existing cast iron table. I am undecided on how deep (vertically speaking) to make it and what kind of joints to use to join the vertical pieces to the top horizontal piece, and would like your recommendations.
I contemplate a design of two 3/4 ” pieces of plywood approx 30” x 18” sandwiched together for the top table and they will rest on and be bolted to the cast iron table. Attached vertically to the bottom piece of the plywood table will be 4 pieces of 3/4” plywood approx 18” wide and hopefully 16” long (vertical), but maybe shorter if it is felt that would add too much weight. Two of the vertical pieces will be attached at each end of the table and the other two pieces will be attached approximately 8” in from each end. Another piece of 30” x 18” plywood would be attached horizontally to the bottom of the vertical pieces.. I would like to add 3 drawers on each side and one larger drawer in the bottom middle. Most of the building plans that I have seen only drop down up to 10”, but I would like more drawer space, but worry that it might add too much weight.
I am undecided as to how to attach the 4 vertical pieces to the bottom table. I think this is very important because the entire table/cabinet and its contents will be hanging from those joints.
My joint alternatives are as follows in order of convenience:
1. Butt joints with glue and countersunk screws fastened from the top for all 4 joints (top table will hide the screws).
The bottom of the vertical pieces could be attached to the bottom horizontal piece in one of the above ways also.
I would appreciate your recommendations as to what joints to use, and whether I am trying to make the cabinet part too big.
