Post your mystery tool.

Exactly right p38arover.
Also known as a "bearing scraper". I've used them many times myself when fitting hand poured white metal bearings on board ships.
I still have my set in the shed in fact.

Certainly not for clock or watch repair 87County :( unless it's a damned big watch, IE Big Ben sized.

Ah, of course. I'd forgotten about white metal bearings. I assume that bearing scraping is probably the most common use for a curved triangular scraper.

Thanks, Shorty.

Definitely a three cornered scraper. Used for "reducing a surface" as the apprenticeship exercise described the long standing exercise for first year fitters where we made small surface plates from rough iron castings.

"Reducing a surface by chipping, filing, and scraping". I still have one of the three little surface plates that resulted from this tedious exercise.

White metal bearings, Shorty. Modern engines!! I worked in ship repair on old coasters that still had up and downers with bearing brasses. Hated scraping bearings of any size.

Still got all my scrapers including some made from files.

I worked in ship repair in the 60's. Some of those old coasters kept going by tight ass ship owners predated WW1. Coal burning up and downers.

In 1987 I was lead fitter on a major overhaul on a Mirlees main engine in a former RN ocean going tug launched in 1932. This was used around the Solomons to tow rafts of saw logs to Honiara.

The Majestics and Battles would have been oil fired steam turbines, positively state of the art technology compared to the old coasters. The corvette which was probably an up and downer.

I went back to Tate a couple of years ago and they still make the 1st year fitting class cut a block of cast iron by chisel and scraper.

What is this one? One of the few souvenirs of my childhood in the 50,s.
