Pendulum jig routs shallow curves
Swinging router jig is great for curved pieces and chair seats.I used this swinging router jig to make curved supports for some laminated seats I built, but it will work for hollowing solid seats as well. You can make cuts like these with a bandsaw, of course, but they will be a lot less consistent. A long threaded rod acts as the pivot on this jig, passing through a steel tube to make it easy to move the router sideways as you work. For wider work, the fixed sides of the jig can be relocated mid-stream. Workpieces can also be routed separately and glued together. I made the jig from scrap sheet goods, tall enough for the 24-in. radius I needed. To make small changes in radius, just change the depth of cut on the router. For larger ones, add spacers under the workpiece or under the legs of the jig, or reposition the pivot bolt.
