This is a simple bearing scraper that came to me in an unusual way. It belonged to an elderly German mechanic who had a garage/gas station in a remote mining town that was still hanging on during the depression
It just so happened a friend of mine was living with his wife on the mining claim that had belonged to the mechanic. The house got water from an old mining ditch and electricity from a generator. It was pretty simple, wood heat and a wood cooking stove. We were there to visit and help with problems they had been dealing with in the old house. The old German mechanic had loaded the attic area with leftovers from his business.
The heaviest item in the attic was a hand pump gas pump. The top was a glass globe or cylinder with increments marked in gallons. You would fill the globe by hand and then fill the car by gravity. My buddy offered it to me before we took it to the dump. The dump consisted of 150 of slope below the road edge that spilled onto mounds of gravel left over from hydraulic mining. I passed in the offer and down the hill it went. Of course the glass broke and I had second thoughts about having saved that piece. It would have been pretty cool. Too late now.
Back at the house and in the attic we continued to remove a lot of old stuff....but didn't make another dump run. In the attic I spotted a homemade wooded tool chest with drawers. I looked through it hoping I would find some old measuring tools even a simple 6 inch scale, but it was not to be. I did find this scraper for Babbit bearings and took it home.
I already had two scrapers I made at the ship yard from three sided hand files, but when a friend asked to work on an old 4 cylinder compressor that it was knocking, I grabbed a hand file and the scraper from the mining claim and went at it. It was great working on a project with a simple tool used by someone from another day.
The stone dressing was something I did. Don't remember if that was even necessary.
I don't think this tool was made from a file as there are voids on the three scraping edges.
