Yeah I neglected to say that. When drums are not 30, 40 years old they can 
be removed without deforming the drum. That small-hole-drill trick I first 
did on my 62 Ambassador in the late 1970's; one of our machinists 
recommended it. It was on a rear drum, but it came off and was turnable 
afterwards.

When I removed the hubs from the American recently, they were not being 
reused, and not in great shape. They did warp from being frozen onto the 
hub. If I'd soaked with Aerokroil and been more subtle and taken more time 
I am sure I could have got them off without harm. As they are I think I 
could get them flat and concentric enouh to reuse if I wanted.
