Reluctant to buy a mobile base and not thrilled with building an apron type base, I had another idea. Watching the NYW with Norm's movable assembly table, it got me thinking of using a similar technique as a mobile base for a contractor style TS. I'm thinking of 2 parallel strips of hardwood or ply that are hinged to the inside of legs of the saw. 4 casters would be attached to the bottom of the wood. The part I haven't worked out is a way to make the wood push or drop "down" to lift the tablesaw "up" making it movable. Release the downward pressure on the wood and gravity (maybe too forcefully?) sets the saw down again. I guess a board attached to the rear strip and on top of both pieces of wood could push the pieces down, but it would seem like it would get in the way of day to day operations with it sticking out the front.
Anyone built anything like this?
