Some new additions

Picked up some new stuff recently. Among the items were these three tools. The try square is a Stanley #20, rosewood and brass, 7 1/2 inches long blade. The bevel gauge is a bit of an enigma. It has no markings on it to identify the maker. What makes it unusual is that the wooden scales are ebony. Disston made a #5 gauge that used a slotted screw you had to tighten with a screwdriver like this gauge but Disston wasn't using ebony and Disston put their mark on everything they made. Who made it may remain a mystery.

The other tool is an Eclipse #256 erector's scraper which from what I can gather is a tool used to prepare Babbit bearings in some way. I've watched a few videos of guys pouring and preparing Babbit bearings for use but none used a tool like this in the process. If anyone has info it would be appreciated. These days it has about as much purpose as breasts on a nun but I'd still like to know how it was used.

those scrapers are designed for the removal (scraping) of high spots on the poured surfaces of babbitt bearing to give it a smoother surface
about the same (think) as a Cabinet Scraper we use woodworking..,,,

The square ended scrapers were usually for scraping gaskets, and the pointed for grooves the triangle bodied ones were used horizontally to scrape with side edges. My dad did some rebabbiting bearings in the shop and on irrigation waterpumps. He had some narrow square tipped ones to cut the oil grooves around the bearing.

In the videos I watched they used the half round scrapers to trim off high spots that had been identified by inking the shaft they were to fit and spinning on the newly poured babbit. Those sort of resemble the spoon style drill bits old school chair makers like to use. It's possible you could make an oil groove with it but the gasket removal or maybe trimming the outer end of the bearing seems a little more likely. It appears to have a high chrome content as it has no tarnish or aging at all. I get the feeling it might have been a pricey tool in it's day.
