rear brake drums

Since I have no lathe, my crazy idea is to use my car as a redneck lathe. Mount the drum on a rear axle facing out, and idle the engine to spin that wheel. Hold a hacksaw blade against the lip to cut it off where needed, then flat file to clean the edge real purty.

In Darter6's photo, it looks like the front drum is 2.5" deep, not 2-5/16". However, what really matters is the distance to the inner hub face of the drum. The rear after-market drums look more bell-shaped, but that might just be the photo. You need to cut just enough lip so the drum doesn't rub against the backing plate. Any extra width where the shoes contact wouldn't hurt.
