When I bought our house the previous owner had asked me if I wanted him to leave all of the scrap wood he had beside the house I said "Sure"
Looking at the pile I was amazed at how much was actually there.
This workbench is from the Mastercraft Essential Workshop book. I built one of these when I was younger with two sheets of plywood for a top and a back on the shelf so nothing falls out. My lack of sheet good scraps forced me to modify the design. Fits nicely into my mini shed workshop.
Note that the picture doesn't show the front 2x4 under the plywood top.
My office cleaned out some old junk and gave me these modular drawers. I new they would make an excellent storage system for my workbench. Overkill...yes...but they were free so I couldn't resist.
