Well it took an hour, but I finally was able to cut a test circle and disk. Seems that the Jasper Tools Circle Jig No. 200 is not pre-drilled for the Bosch Colt plunge router base. Who knew? Pretty sure I saw in a review on Amazon that it was, but I couldn’t get the holes to line up once the centering pin was installed. So I had to drill the plate for my pattern.
