Anybody Guess What This Is?

looks like a old bearing scraper
Bingo. It is a tool steel scraper for hand fitting large white metal bearings.
In my younger years, I did quite a few of them.
large ships still use white metal bearings on their line shafts, but in the kind of vessels we work on, split roller bearings have become the norm if the vessel has a intermediate line shaft.

good guess.
 
When I was 16 or so, I was reloading 38 supper and 45acp with bullets I cast. My grandfather had just died and in his shop was a big ingot of what I thought was lead.
So I inadvertently created the first armor piercing hand gun rounds. Babbit actually shot pretty good. I wonder now what the pressures were like?
 
There may be a few members that can relate to that tool but for me that photo brings back unpleasant memories. Where I worked in a steel mill shop, there was part of it where electricians rewound armatures. They'd pour the babbit bearings and we'd chuck them up in the lathe and bore them a little undersize then scrape them to fit. We also turned down the commutaors and with tool made from a hacksaw blade, scrape in between the copper bars. Motors were big, bearings were heavy, not one of my favorite jobs.
 
We still have some older hydroelectric units that run Babbitt bearing. I’ve had the pleasure of fitting a few sets. last one we had someone drain the pillow block oil for the weekend and didn’t make sure the deflector was Closed and locked. The hydraulics bleed off and started spinning the pelton wheel. good times
