With the DRO's and rotary table it was super easy. I have a bolt that I put a small hole in the center of the head so I can mark the center of the RT. I measure off the hole in the center of the RT and go 1/2 the diameter of the largest pattern and start drilling at 0° then 72° ect for all five. Knowing I was going to have 4 bolt patterns I divided there start points equally between the first hole and second one. I had to do it on a spread sheet in excel and print it so I could get it right
