I built the “Basic Mobile Workbench” following Steve Ramsey’s design about two years ago. Having a workbench on wheels ‑along with the a roll-up extension cord in the middle of the garage- really changed the entire way I make anything in the garage shop. But I put some pretty tiny little casters on it, and though it rolled ok, I’d always wanted to improve it. However, since I built it at the height of the table saw, there was not way I could raise. Well, with a new table saw (more to come on that soon), I decided now was a good time to put on some bigger rollers.
I cut off the legs below the cross members using my late father-in-law’s old reciprocating saw. That old Craftsman is crazy powerful and made short work of it. I also cut some support bases out of 3/4″ construction plywood to level out those cuts and give the lag screws something meaty to attach to. The overall effect was to raise the top surface about an inch and it rolls better than ever.
