Can anyone offer advice to the best way to make a perfect inside cut from and outside template? Specifically, how to make a perfect hole to recieve a router table insert.
All I can think of is using a small guide bushing to make a secondary template with a bigger hole than the insert (or I guess I could just use a trimmer/template follower), and then a bigger bushing to make the final hole exactly the right size for the original insert.
I guess this would work OK but it sounds elaborate. Is there a better way?
