[Healeys] Brake drum theory question

[fiat500f at aol.com]

Brake drums - ugh!

When a brake drum is turned (cut), how is the drum secured to the cutting
machine?  By the center hole, the lug holes, or the outside of the drum?  I
think I may have some seriously out of round drums, though they were cut (with
little use since) by the previous owner.  New master cylinder and wheel
cylinders, no air in the system, but I still have a long pedal travel (firm at
the bottom), but I can't get the shoes any closer without binding on the
drums.  I'm thinking the drum should be cut while being held in the same
orientation as it will be used on the car, with the lug holes, yeah?  I'm also
thinking that the center hole is not necessarily central to the drum center
point of the shoes, but the lug nut holes will hold the drum exactly like it
will be held by the wheel hub.  Opinions.....
