No CNC here, just a lexmark printer, punch and hammer... I didnt turn the rotor into a hub just yet... I wanted to measure the runout of the hub, or see if there was any before I cut up a brand new rotor.
As far as the rotor its from a 2003 newer dodge ram 1500. As far as the new pattern I used a template I created in Autocad. Before I attached it to the face of the rotor, I got a pick and poked a small hole where the chevy pattern was (makes center punching it supa easy. I attached the pattern to the face of the rotor with some stuff called butyle aka dumb dumb (it's like sticky tack but for cars) and stuck it onto the face of the rotor. Turned it upside down and moved the pattern untill everything lined up. Silmply took a center pinch and hammer to mark the new pattern. Removed template and center punched the new holes a second time. Used a 1/8 bit to start with, then progressed to 17/32. Later I chosed 17/32 becuase it was a hair larger than 1/2 to give me a little wiggle room incase a hole was not 100% on the money. I will put a picture of the pattern I am refering to.

edit:
heres the screenshot of the pattern I whipped up... the ones with the (X) is the dodge, and the other... obvious.
