I've never had to clean up anything. I've always cut the holes through the drum and the drum will lift right off. Now......if you're wanting to remove the studs from the hub, you might clean up a little around whee the stud comes through the hub. If you knock the studs out with too much material left on them, you can damage the hub.
Hey RustyRatRod, do you think a 3/4 hole saw is too big, I just found one I already own in a box of my Dad's old drill boxes. I don't care about the drums as I have new drums.
