I did make a drill guide ‘sleeve’ to fit inside the splayed hole and have the ID be the tap drill for 7/16-14. I was going to use that for if I had to use my bridgeport with the head tipped. Now that im doing it in the cnc. Im not sure if I am going to use it or not because I am planning on installing the caps on dowels with block set on the 18* fixture side. Then tramming center zero in cap and spot facing, center drill, tap drill then tap.
