I used the same diagram from twinturbo. He should patent it, it's an easy and sturdy cart. Once I sell the spx I'll replace the vinyl with carpet, it was just kind of a quick fix because I lack the patience to wait to get carpet.
I need to get a miter saw for future projects, using a circular saw really sucked!
