Here's the armature after I cleaned it and had to take a cut of about .003" to level the bars. I undercut it with my ATLAS hobby saw, then polished it. I wrapped a piece of construction paper with tape around the commutator and gave the windings a light spray of clear lacquer.

I'll have more pictures about the process, but to answer a question just asked, I use felt in the rear seal as shown inside the steel retainer. I've only had to replace one felt, as the original is usually still in good shape, like this one shown. I pack the rear bearing with Mystik JT-6 High Temp grease, and probably wouldn't have to worry about it again, but just to be safe I'd give it a couple drops of oil once a year. If the rear bearing is shot then you can replace it with a sealed bearing.
