I used a 1 lb hammer and banged around the edges of the drum. Since I was not going to re-use the drum, i didn't really care if it broke or not (which it did not), but i don't know if any damage was done in the process. It did take quite awhile (5-10min), but it finally vibrated enough to break loos from the studs and the center part of the axel.
