I got a home made one that looks like this. Somebody had turned a screwdriver into a paint can opener. Mine works good.
If this one was "rigged" by PO it's escaping my eye uncleaned. I need to clean it now and see what more I can find.
Would it work for scraping oil grooves in babitt bearings?
<shrugs shoulders> I dunno! Never worked with Babbitt except in bridling the horse head of a well.
Seal puller perhaps?
That was my thought, but it certainly isn't anything like the modern day version I have.
