I have the same box. I was going to purchase a second and bolt one of my workbench tops to them, and make a mega bench, but they didn't have one in stock for a 90 mile radius. for what gas prices are, I would have bought the 44 inch box if they had it in stock at my local store on Sunday. hahahaMy Sherline mill is mounted to a plywood base and lives on top of a 26" US General tool chest. The Micromeark is about 2x the weight but I doubt that is a problem.
