Circle Cutting Templates

Before leaving the topic, however, here's a simple-to-makc pair of templates that can demonstrate concretely how versatile and useful templates can be in routing curves and circles.

Each template has several holes cut in it. three in one. four in the other.and each corner is rounded at i different radius (eight in all). To tout a matching hole, you simply chmpthe template to the work, fit a pattern hit in your router, and let the template guide the router through thecu:.

But wait! There's more!

Each template hole can be used to rout at least five different sizes of hole. Use guide bushings to offset the bit from the template edge, and you'll reduce the diameter of the hole that's routed. If you use a Winch bit with a guide bushing whose outside diameter is Y* inch, you'll reduce the diameter of the template hole by Vi inch.

The siring chart on page 182 lays it all out for you. Two different guide bushing sizes arc used, in combination with three different bit sizes. If you have a broader selection of either bushings or bits, or both, you may be able to come up with some additional sizes. Just as an example, a Winch bit used in a Mc-inch O.D. bushing reduces the hole Mc> inch.
