I think you are on the right track. Just go easy on those brakes the first
few miles and the shoes will clean up the drums. As long as they run true.
However, there is more ways for them to wear. Drums often wear a concave or
bell-shaped pattern. Takes a lathe to fix that. Also, the likelihood is
that that old car will have plenty of meat to turn them further.
If this is a restoration, with new shoes and hardware, do turn them. If
you are just trying to get an old car unning, you may get away with not
turning them.
But hey, around here it's on $5 each to turn drums.
