Tip of the Day: The next time you need to move something big and heavy, save your back and build yourself a workshop dolly. Make a rectangle with two-by-fours, using lap joints at the corners. Attach the casters just below the joints. You can also butt the joints together and add a sheet of scrap plywood over the top to give it stability. You can staple a little recycled carpet over the dolly to help keep loads from slipping off and to protect delicate finishes.
