These workbench plans consist of a torsion box top and a cabinet lower. The torsion box is roughly 3.5″ thick, but can easily be made any thickness you desire.
The download includes simple PDF plans with a cut list, and the sketchup file for exact dimensions allow easy modifications.

Don’t buy any of that junk at the local big box store! Build yourself a workbench that will last a lifetime (or two) and you’ll be money ahead! I recommend making the torsion box section from MDF, and the cabinet section from 3/4″ cabinet grade plywood, and seal it with some wipe on polyurethane.
