Flaco Joe Posted February 6, 2022 Posted February 6, 2022 Does anyone know what this is? It was found in a pile of reloading tools. Thanks
Flaco Joe Posted February 6, 2022 Author Posted February 6, 2022 Sorry about the image link. It shows up for me. I’ve attached some still photos. It is knurled cylinder with a spring loaded center pin. The center pin will draw backward out of the knurled cylinder and snap back under spring power when released. I thought it might be a center punch, or maybe a tool for removing a primer? But the spring feels too weak to be an effective de-priming tool. The center pin is graduated on the shaft. I tried to get some of the numbers that are roll embossed on the sliding center pin. Thanks
Crazy Gun Barney, SASS #2428 Posted February 6, 2022 Posted February 6, 2022 A depth gage graduated in millimeters maybe?

Crazy Gun Barney, SASS #2428 Posted February 6, 2022 Posted February 6, 2022 Looks like 95 is the largest marking. But the pin doesn’t look to be 3.75” long, so I have no idea. Looks like the pin and the housing may be that long., but odd that the measurement would be from that end of the housing.
Singin' Sue 71615 Posted February 6, 2022 Posted February 6, 2022 Have you met....?? Oh, sorry...not the kind of TOOL you are speaking of.
Sam Sackett Posted February 6, 2022 Posted February 6, 2022 Wild stab here. Possibly a depth gauge for measuring blind holes?? You picked a good challenge. Sam Sackett

Sam Sackett Posted February 6, 2022 Posted February 6, 2022 What is the reading when the pin is all the way in? How long is the pin end when the tool is at the highest reading?
Nickel City Dude Posted February 6, 2022 Posted February 6, 2022 Can you turn one of the knurled nobs and will the pin lock at that point?
Joe LaFives #5481 Posted February 6, 2022 Posted February 6, 2022 Does it have a spring assembly inside?
Lazy Eeyour Posted February 6, 2022 Posted February 6, 2022 Almost the same but close https://www.starrett.com/metrology/product-detail/829A
Imis Twohofon,SASS # 46646 Posted February 6, 2022 Posted February 6, 2022 Im going with depth gage. Imis
Frontier Lone Rider Posted February 6, 2022 Posted February 6, 2022 From one who taught Machine Shop years ago, I would go with Depth Gauge. Measuring brass case overall length without having to use a set of Micrometers. Looks like the big brother to my tire tread depth gauge.
J.S. Sooner, SASS #73526 Posted February 6, 2022 Posted February 6, 2022 Looks like it would be an aperture hole gauge. Insert into a hole deep enough or a through hole, pressing up to the base and read the hole diameter on the scale. Could have been used to measure flash holes, although the measurement wouldn't line up the scale properly, being the flash hole is below the base of the shell, depth would have to be factored in for a correct reading. Drill a 5/64" hole in a piece of sheet metal. Insert the gauge into the hole and the reading on the scale should be around .078.
Flaco Joe Posted February 6, 2022 Author Posted February 6, 2022 Answer to all the questions: The last measure mark is “65” and when the pin is fully depressed, it would read a little past that to 60. No, there is no way to lock the pin at a particular point. Yes, it is spring loaded and the top knurled end cap can twist off to reveal the internals. Sure, I’ll sell it! I never needed it before today and without knowing what it is, likely won’t ever need it after today. Thanks for helping with this question, everyone.
J.S. Sooner, SASS #73526 Posted February 6, 2022 Posted February 6, 2022 The pin on looks tapered. If you can take a couple measurements with a micrometer or caliper, the smaller end should be about .060 and the larger end .095.

Sam Sackett Possibly a case depth measurement tool or for measuring the height of a shotgun shell wad collumn.

Set the gauge to .90 and measure the diameter of the pin just at the point where it protrudes from the base. Set the gauge to .70 and repeat. If the diameters match the gauge, then that's your tool. Place the pin in a hole, slide the collar until it contacts the surface of the item with the hole in it, read the diameter of the hole. Not as accurate as a set of pin gauges, but it will get you in the ballpark.
Yusta B. Posted February 7, 2022 Posted February 7, 2022 It's a Herter's flash hole gauge. I have one exactly like it. Used to sort cases based on flash hole diameter.

DeaconKC Posted February 8, 2022 Posted February 8, 2022 @Buckshot Bob , thanks! I thought I had seen all the Trunk Monkey commercials, but had never seen that one!
