I'll start by admitting I didn't do a great job photographing every step, but that's partially because this was a custom job for my friends, and I wanted it to be a one-of-a-kind piece, so I didn't upload plans like I normally would. The top is built in three sections for transportation and convenience. The top pictured is one of two that creates the top of the T. It is 3/4 walnut ply, cut to 23" in width and 56 inches in length. The frame is walnut, cut to about 1" thick with a 1" rabbet on which the table top rests and is glued to. This makes the desk 24" wide by 57" tall.
