Woodworking Bench Casters. Ideal for use in all workshops, screws directly to workbench. Thats the casters i have to work with, the studded kind.
Or more on qualifying items offered by rockler woodworking and hardware.
I plan to mount them atop a 2x4 as in the drawing (gotta get sketchup running one of these days). This is the benches outdoors category of information. Leveling casters make this bench mobile, giving dirk the ability to move it around the shop, or from if you end up building this bench, be sure to pick up the casters dirk used; Once your lumber is thicknessed, start working on the top.
