I’m building a bow-front cabinet and need to find the radius of the bow so that I can make some templates, using a router on a trammel. How can I find it?

ANSWER:
From your plans, you can find the width and height of the arc. Then you can use a simple mathematical formula to determine the arc’s radius.
Fun with Algebra: The width and height of an arc can be used to determine its radius. Here, the width is 16 in., the height is 1 in., and the radius is 32-1/2 in.
