I used the ideas of many and added my own as well, with the bottom shelf and 30 degree edge cuts on legs and bottom edge of table top. I constructed this in two separate parts, frame and inserts. I stained the the gray and brown parts separately then finished assembly and clear coated. I used nine 2x4x8' and one 1x8x6'. Table top is 60" x 22". I had to use one piece of 2x6 and rip to 4" wide. This filled the 1/2" gap I was left with on the gray part of table top.
for the top coat I used Rust-Oleum Ultimate Polyurethane in Semi-Gloss, three coats.
