Which reminds me that you needed to have a sharp cutting tool mounted properly on your comm lathe, which I don't regret not having to deal with any more. I also don't regret having to settle with the carbide cutting tool because I couldn't afford the diamond tool.
I always trued to a shiny finish, and deburred the comm afterwards. They Carbide tool did a great job too, just required a bit more time and patience and you would easily be able to make quite as long.
I still have my Reedy Comm Lathe and Motor Analyzer. Also have my brush Cutter and Hood Alignment tools.
I still run brushed motors in all my older vehicles that are sitting on the shelf lookin period correct.
