Last week I asked how people sanded the edges of round cutting boards. I got some excellent advice and based on that I made this jig. Originally, I had thought to use the band saw to cut close to the circle, then use a router circle cutting jig to clean up the edge and finally sand the routed edge to yield a smooth edge.
My first step was to make the base from a rectangular piece of plywood large enough to be easily clamped to the table of the BS and the disc sander. Then I added the cleat to hold the rectangle square to the BS blade and disc. Finally, I routed 2 slots in the base, one for the BS and the second for the sander. The slots need to align with the optimum location for each tool and since that point is centered for the BS and on the sander is toward the left edge, I decided that 2 slots would be preferable.
The second phase was to find a bolt that would act as the pivot and drill corresponding holes to accommodate the bolt, nut and washer in the piece that would become the round platform. I can adjust the radius of circles by sliding the bolt one way or the other.
Finally, I cut the platform to its finished round shape and sanded the edge. The jig worked well. This platform is 16” in diameter and will work for CBs that diameter and larger. I will use double stick tape to attach the blank to the platform. I will need to make a smaller platform if I decide to make smaller CBs. Thanks for looking.
