For the ball housings, I used a 3 3/8” hole saw to start. I put a solid rod in the centering bit so it wouldn’t walk and drilled it nice and slow. The surface isn’t flat and the saw really wants to move around so a firm hand and slow speed are key. Then I opened it up to the final size with the belt sander.
Time-wise, it probably took me a couple of hours to fit all 3 vents.
