Jim :
I checked both my manuals, they don't list a maximum drum oversize, nor do
they advise turning the drums.
IMO, if you have a specific problem (pulsating pedal, badly scored drum,
etc.), you should probably replace the drums. Otherwise, don't turn them.
Most people will tell you that not turning them will shorten the life of
the shoes, but I don't believe it. The shoes quickly conform to the
surface of the drum, and unless the scoring is severe, use only a small
fraction of the thickness of the shoe doing it. Shoes are a lot cheaper
than drums !
I'm still using an old bottle of Armstrong shock oil for my lever shocks.
Seems like I got it from Whitney, but I haven't seen it in their catalog
recently. Moss only wants $10/qt. Motorcycle shock oil would probably
work fine (and is available in a wide variety of weights), but I haven't
tried it yet.
