Yes Jeff, been turning commutators for over a half century believe it or not. Pop was an old school mechanic trained in the 20's and they had to be able to do every phase of the trade to be called a journeyman mechanic. He taught my brother and me from when we were little kids so I’ve been at it since the 40’s.
The picture is a little blurry but if you blow it up to the original size you can see that the groove has been cleaned out. I've got special little narrow tool steel scraper hoods to clean them with and not widen out the grove.
