Re: Brake drums
I always measure the cast iron type drum before considering a brake surface cutting process. Most shops will not refinish them if they are even close to .060" oversize and exhibit uneven surface wear. If they have a lot of meat left, at least it's worth the effort.
Ammco brake lathe units can be refitted with the 11/16" Arbor and used with proper mandrels but they require good surfaces to center up. Even the Barrett Drum Dokter can have problems if a hub is bad. Ford rear hubs can be problematic to center if they exhibit too much wear or damage. If so then a person may need to replace them with serviceable parts. An out of round drum wont work worth a damn.
