Thanks all
Tried with a sharpened awl, all it does is wedge itself in the corner of the key & keyway. I'll try again tomorrow
I've read about stippling (some old time machinist call it a strawberry fit) but am reluctant to do so for 1 reason. Years ago, I worked for a company that used very large, 48" ID, as I recall bearings. If the mating surface of the outer race wasn't perfect, the mating surface finish affected the longevity of the bearing, which could be audibly heard (and measured using a transducer). Granted, these are only 1.5" ID bearings, but don't want to touch this again, if possible.
Also did a web search, interetsing find. Not sure if I agree but this is from a bearing standard article.
