BAND SAW CIRCLE CUTTER

Mark Mazzon came up with this handy circle cutter. It is used mainly for cutting solid bulkhead disks in wood, fiberglass or even metal, with the proper blade. It is a work platform designed to fit on the deck of your bandsaw. Through the center is a channel fitted with a sliding tongue with a ¼" pin placed in the center as shown below. The tongue can slide positioning the pin at various distances from the band saw blade. This distance is your radius.

As an example if you wanted a 4" diameter bulkhead you would cut a square of wood ¼" oversize so you would have a square 4¼" x 4¼". Measure in from one edge 2" and then from another edge 2" (this is the radius of the circle you want to cut) and draw a center X as shown in the diagram.

 

Drill a ¼" center hole on the center X.

Now adjust the sliding tongue so the center of the pin is 2" from the blade, This 2" is the radius of your 4" circle. Lock or clamp the slider in position so it will not move. Place the wood square, or even a stack of them, on the pin so the blade is positioned flat against the starting point of the desired circle. Turn on the saw and spin the wooden square while it is held centered by the positioning pin as shown below. - Simple and clean.
