I had about eight 2×4 beams left over in the garage and used these to create the frame. I knew I wanted to add a sliding draw for the computer keyboard and so I left a gap at the front left-hand side for this.
Pocketing is a joining technique where you drill an angled hole into the side of the wood and drive self-tapping screws through the holes.
The basic dimensions were constructed around the width of the keyboard slide, and placing the computer monitor at eye level when I was seated. Starting from these few basic measurements I built up the frame piece by piece.
I did very little measuring — once I had the 3 vertical back “pillars” spaced correctly I just held up the next piece and marked off where I should cut. I brought over the chair and checked the general layout to make sure everything was within reach.
I sanded down the 2x4s and put a coat of Polycrylic (again a leftover) to seal it and stop splinters from lifting up.
I also knew that my oscilloscopes, signal generator, and soldering iron needed to be elevated — so that any trailing wires don’t end up getting knotted on the main work surface.
