Hand scrape? A triangular (three-sided) scraper will work.

If you blue the bearings, and gently scrape off just the blue?

I recently fitted new bronze bearings to an ML7 lathe. They were too tight
( which is how Myford deliberately make ém ) and I hand scraped them using a
3 cornered scraper and bearing blue. It was a Saturday afternoon. My
favourite coffee and the football on the radio made the hours pass sweetly.
Totally worth the effort for the most impotant fit on your lathe and helps
keep the old skills alive that got us were we are today.
