John, My gantry is only about 18 inches tall. The radius was created by marking out with a pencil and piece of string - I then cut out a pair of guides to run the router along. In order to radius the dish I drilled a 6mm hole in the middle and in a slab of MDF below it. Feed a dowel through both so the dish is able to rotate around the center. I fed the router in from the outside of the dish until about half of the diameter of the 20mm bit was cutting and rotated the dish (its a bit of a two man job). When one full circle is completed move the router further in until you eventually reach the middle and cut through the dowel. drop a bit of superglue around the dowel at that point and the dish is complete. Maybe not as accurate as the pendulum method but I'm scared of heights. Lots of other good ideas in there - wish I had cash and space for a table saw! Little Steve, How you keeping? I also made the headstock jigs... saved a lot of time! How easy is it for you to get into London from the North of France - I'm working in Stevenage at the moment?
