My shop is not very large, 16' x 24', so most everything is on casters. Knocked together an extra bench on casters to open up more workspace and storage. It's a 24" x 72" top with a 19" x 19" downdraft area for sanding. I use a small downdraft box all the time, the larger surface will come in handy. Plus I made it extra tall to save my bad back. I had my second round of injections today and told I'd be on a 40lb limit from now on.
