Well, I think it depends if you care what the result sounds like. You 
can go a long way by skirting if you are prepared to take lots of 
metal off, but you would risk ruining the tone.

I recall reading somewhere (if I could remember where, I would check 
the reference!) that during the various remodellings of the Appleton 
ring, one of the bells was tuned up a semitone and then down again - 
or vice versa. I'm sure someone on the list will know the real story.
