|Here's a before shot....notice all of the random things accumulating around my tool boxes!|
1. Find a top you want to use. I found an old counter top from a kitchen, but you can pick up some High Density Particle Board (HDP) from your local hardware store. Cut it to a size you want and put some 2X4 or 2X6's around the ends for a frame. Glue the bottom of the boards, clamp them together with the bottom of the table, and screw the two together. Be sure to screw from the bottom up. You don't want to cut a hole in your table top.
2. Cut your legs to your desired height. Take a 2X4 and screw it to another 2X2. Do this four times, one for each leg. This allows an easy fit into the frame on the bottom of the table. If you want to add a shelf to your bench, screw another piece of 2X2 in the corner of each leg so the shelf can rest on it. Number each leg and frame just in case you need to take it down. (more on this later).
3. If adding a shelf, find a scrap piece of plywood, measure and cut it according to the inside of your frame on the bottom of the table. Pre-drill the plywood because it can split easy. Screw the plywood into another frame of 2X2s. This can rest on the inside of the legs you made earlier. Screw the sides of the legs into the frame of the shelf to pull it together. Screw the back frame into the studs of your garage wall for extra support.
4. Vice (optional). Determine where you want the vice on the bench and mark the four holes with a pencil. Drill a hole through the table big enough to fit a 3/4 inch bolt. Screw the nut and bolt together with the Vice attached.
The finished product: A nice-sized work bench for me to work on, and a more organized garage.
