I just bought some floor standing power tools and wanted to keep them mobile. Rockler has a sale while supplies last at their stores for $29.99 plus tax (Regular $55) if you you are interested (2 per customer max, but they allow more on a second ticket). I thought this was a good deal for a steel base with 400 lb. capacity. It would be hard to buy the wheels/casters and materials for this price, much less your labor to make one. Anyway, I am just making special this known in case it helps someone.Ed
