I have gone for a round mobile donut style bench/tool holder etc Its all due to the amount of space I currently have. I'm using the ends of old cable drums and the wheels are from a 44gal oil drum dolly. It's still a work in progress and probably will be that way as I adapt, change my mind etc as I go along. The next step will be to lift the toolrests off the bottom shelf onto their own shelf. Then leaving the bottom for the heavier gear ie my carving jig, sphere cutter, small hollowing rig etc
