I designed my workbench to be the appropriate height to act as an outfeed support for my table saw. But, when I replaced my old table saw, the bench was suddenly too short to serve that purpose. Instead of building a new bench, or trying to raise it, I built a roller support that clamps on my bench. The plug for the inside of the PVC roller is cut using a hole saw. The pilot bit matches the size of the threaded rod. PVC roller. I constructed the roller out of some PVC pipe that I had in my shop. I plugged each end with plywood, and a length of threaded rod fits through the pilot hole in the plugs. The rod serves as an axle and allows the roller to spin. A pair of supports on each end raise the roller to match the table saw height. A large fender washer on each end spaces out the roller from the supports. Everything is then attached to a plywood base. To use the roller, I simply attach it to my benchtop using a pair of small clamps. With the roller installed, my workbench once again is the perfect outfeed support.
