Excellent points, all. Precision set up is half the battle. Given your background, I think you would enjoy some of the videos over at He does some really nice videos using dial indicators, etc., to set up tools.

Do you have a centering pin for your router? It’s easier to use for getting your plate centered on the base than a dial caliper, less iterative. Actually, I have an inlay set that includes the centering pin. It was less expensive than buying the Porter-Cable cone.

P-C put out a supplemental manual for the 4200 that is useful for expanding the capability of the jig. It’s available at but have not been able to find it on their site. Actually, I’m not sure it is possible to find anything on their site. They need to test it using actual people.
