With the great price recently on the Kreg Bandsaw Fence at Hartsville, my old circle cutter rig would not work since it needed the edge of the table to prevent tipping and the board could not pass the fence. So, new rig #4 was developed including some improvements that came form other woodworkers in our local club.

The table is 1/2" MDF and uses a section of 3/4" wide by 1/2" deep track from Rockler. The runner in the miter slot is red oak (leave runner long for alignment when table pulled back to load material), and supports and front board are scraps. There is a "T" hinge inset on the rear with the strap bent to hook under the table to prevent tipping with weight on the outer section before the table is pushed against the Kreg rail and lower guide preventing tipping. A Tee Nut was installed in the front board and bolt with locking nut provided to set the alignment of the blade front with the center pin, #6 machine screw with head cut off and pointed. I used a self tapping screw to tap the holes in the track (broke off the first one, so remembered to add some oil for additional tapped holes). All the material was in the shop, but cost for material should be less than $15 if one went out and bought individual items. A circle cutter for the bandsaw is really a great asset. It made quick work of preparing 10 bowl blanks, and has some flat work heading its direction soon.
PS - the Kreg fence is great also.
