Built an Adam Savage (of Mythbusters fame) tool cart yesterday. The design is based upon his "first-order of retrievability" theory. I think I have been operating under 4th or 5th order - now which tool box, drawer, or cabinet is that tool I need located

So I've condensed 4 tool boxes and a cabinet into this. I love it. Everything in one place, visible, and retrievable.
I used one sheet of plywood, 4 caster wheels and some scrap wood pieces I had laying around. $45, all in.
