I have a jasper jig and I'm ready to cut the hole for the sub. However, how do I ensure the center point for my dowel pin will be directly in the center of my circle. Normally, I mark an X from edge to edge. The circle isn't in the center of the board. Any tips?

If you have a speed square or something like it this works.

Put the pin wherever you want it.
