I did mine for my AA the redneck way. I used a bench belt sander. Trial and error. Took small amounts, try fit in drum, fielders gauge, try fit, repeat...
You could line the drum with sand paper, insert shoe and carefully rub.
Location, location, location. Where are you?? There may be someone down the street from you who could do it.
I don't understand why people are reluctant to post their location??

I saw someone posted that here once and others said it wouldn't work perfectly because you are arcing it to the radius of the drum minus the thickness of the sandpaper.
It still seems like a clever idea to me. I don't think the thickness of the sandpaper would make a huge difference.
i have a friend(in his eighties) here that has worked on a's most of his life. he has a way
to arc the shoes in a press to make them fit the drum. in fact he gave me his old brake shoe grinder, never uses it. just bends the shoes til they fit the drum radius.
i can do it for u dave i am in conn by bradley air port 10.00 per shoe 8608835290
