I have a never used HTC Products mobile base for my Powermatic 66 table saw (model HPS-10-G) which can expand to accommodate the 36" table extension on my saw. The fixed dimension is 24" wide with the length expandable. It weighs too much to ship so, I would prefer to sell it to somebody in the San Francisco Bay area. Contact me and we can discuss price and pick-up options.
