Identify these tools?

[Jay Aubuchon]

As we prepare to move my mother-in-law, I am going through some tools left behind by her late husband. I think most of the good stuff is long gone, but there are still some interesting things. I'd appreciate any help identifying 3 items. It may help to know that he was a machinist for a significant portion of his working life.

The first item is about 6 3/4" long. The business end is triangular in cross section, though the 3 sides are slightly concave.

The second item is a set of three, each about 3 1/4" long.

The third item is about 6 3/4" long.

#2 - inside diameter measuring tools
#3 - looks like a drift which could be used for knocking out a taper within a drill press quill

#1 looks like a burnisher for a card scraper.

[Wes Grass]

#1 is a scraper for deburring.

#2 are called 'telescoping gauges. Used with a micrometer generally.

I agree #3 is a wedge for morse taper tooling.

I agree with Wes.

[Andrew Seemann]

#1 could also be a small Babbitt bearing scraper.
#2 yes, telescoping gauges
#3 yes, Morse/B&S taper drift

[Bill Dufour]

#3 is for driving out #3 morse tapers. It is numbered. You 1/2 drill press is probably #2 MT. It would probably work for #2 as well.
All others are as already noted.

#1=scraper. I have 2.

I agree with Wes and Andrew. I remember my engine builder/machinist used a scraper very much like that one for chamfering camshaft bearings after he installed the bearings into the engine block. I own and use one very similar which I use for scraping/deburring edges. The telescoping gauges (snap gauges) are generally used to take a measurement on the inside of a bore. The snap gauge is then measured using either a micrometer or caliper to determine the actual dimension.

Thanks! Now I know. I even found a video showing how the telescoping gauges are used.
