The first thing to do is select the size of bit and dia of template guide that you intend to use. The simple formula for making the template is; template guide dia. minus bit dia. plus the size of the inlay.
Let us say you intend using a 1/2" bit and a 3/4" template guide, then we have:
3/4"-1/2"+5"=5.5".......by: 3/4"-1/2"+7" =7.5". That is a template with a rectangular opening measuring 5.5" x 7.5"
The simple way to make such a template that is accurate is shown in the photograph, four pieces cut so as to leave a cut-out of appropriate size.
