Router Circle-Cutting Jig
Oct 25, 2005
This inexpensive but accurate circle-cutting jig is made with two 18-in.-long rods that fit the guide holes in your router. Cut threads on one end of each rod and, using nuts, attach the rods to a length of 1/8-in.-thick steel bar, as shown above. Take care to ensure that the rods are parallel and spaced the right distance apart. For the pivot, attach an eyebolt to the center of the steel bar with a hex sleeve nut and a wing nut. For the center (pivot) peg, I use a 3/4-in. dowel, shaved down slightly to fit the center of the eyebolt.
