I've always clamped a radius dish to my workbench when I voice tops and have to rotate it and re-clamp all the time to get different angles which is a pain. (or walk around to the other side of the bench) The other day I had one of those Far Side "Look what Og do" moments and rigged up a central pivot peg with a 5/8" dowel and a simple hold down clamp. Now I can stay in the same spot and shave with wild abandon at any angle.
