Lloyd, I can guarantee 100% that I will never scrape any machine ways
that are worn, as a restoration project. I will keep this scraper for
some minor jobs, like repairing dings.

Also, if you ever end up owning a vintage British motorcycle that
doesn't leak oil, this will rectify that situation in short order.
Couple quick swipes across the bottom face of any gasketed surface will
restore the bike's original ability to leave puddles of oil on the floor.

That's why the Brits never developed much of a computer industry. They
couldn't figure out how to make them leak oil...

Funny you should mention - it really did happen.

Back in the 1960s or so, Univac 9400s had a hydraulically actuated disk
drive. When it worked, it worked well. But not for long. I never knew
the reason, but these drives were famous for breaking and spraying oil
everywhere. Puddles were normal. These drives didn't last long in the
market.

IBM had (and probably invented) hydraulically actuated disk drives, but
I don't recall that they tended to spray oil.
