This is what I came up with for cutting and/or truing circles.
I never built a circle jig for my bandsaw, it just seemed too wonky to support the work piece, and the router base type always made it difficult to secure the workpiece to the table without having to reposition clamps.
My Circle Jig attaches at both ends with qwik-clamps to the extension table and the fence. I can then use my rout-r-lift for cutting. Multiple passes are fine as the piece just stays where it is and I adjust the height of my router.
It cuts very, very smoothly, and because its supported on both sides, is very stable.
I can use a centering piece double taped on the workpiece as in the photo, or I just drill an 1/8” hole in the wood. Due to the ability to tighten down the center pivot pin, the piece is very secure.
The pivot pin is a ground and polished bolt. On the bottom of the pivot pin holder is a “T” nut and on top a locking nut and washer. These work together to both adjust the height and the position of the pivot pin.
-- Im so impressed with what people can do, and I wonder how they do it. Thats what keeps me doing it.
