I had a similar issue with space...I made a base out of 2x12s (to get them off the floor) the base was 24 in x36 in rectangle topped with a piece of smooth osb plywood. I then made a tray that was 36in x 48in made out of 2x4s and osb plywood. I lined the tray with poly, prior to lining the tray I drilled a hole (1/4in) through the center of both the tray and the base then inserted a small 1/4in bolt long enough to penetrate through both layers of plywood. now you have a rotating table (manual of course). I've to figure out how to power it (but i will) Good luck...
