JHCC Posted September 26, 2020 Share Posted September 26, 2020 The tool pictured below came in a box of random tooling I just bought recently (for its excellent selection of Starrett dividers and calipers). I’m planning to sell it to help offset the cost, but I need to know what it is first! The tool is about 7-1/2” long when completely stretched out, and the round pieces on the end are 1/2” in diameter. It was suggested elsewhere that it might be part of the base for a dial indicator, but I’m open to other suggestions. Click on photos to enlarge.

Anachronist58 Posted September 26, 2020 Share Posted September 26, 2020 The proper name escapes me at the moment, but the solid cylinder goes into the collet or chuck of a milling machine, or drill press,for example, and a test indicator into the bored cylinder end. then the machine spindle is rotated as the indicator tip is in contact with the table, thereby "tramming" the angular relationship between spindle and table. Many other uses..... No coffee yet, but definitely a test indicator attachment. Robert Taylor Quote Link to comment Share on other sites More sharing options...
JHCC Posted September 26, 2020 Author Share Posted September 26, 2020 Thanks, Robert. Let me know if the name comes back to you; I plan to list it on eBay, and I want it to be properly searchable. Quote Link to comment Share on other sites More sharing options...

JHCC Posted September 27, 2020 Author Share Posted September 27, 2020 Yeah, that's the closest I've been able to find, although all those seem to be round rather than square. Well, I'll put it up on eBay and see what happens. Thanks for your help! Quote Link to comment Share on other sites More sharing options...
Anachronist58 Posted September 27, 2020 Share Posted September 27, 2020 That one is a unique, one-off, custom crafted tool...... Quote Link to comment Share on other sites More sharing options...
BIGGUNDOCTOR Posted September 27, 2020 Share Posted September 27, 2020 That one looks like a homebuilt, not a factory item. Quote Link to comment Share on other sites More sharing options...
JHCC Posted September 27, 2020 Author Share Posted September 27, 2020 I think so too, but it’s definitely well-crafted. Quote Link to comment Share on other sites More sharing options...
Irondragon Forge ClayWorks Posted September 27, 2020 Share Posted September 27, 2020 I think that one may be old. I remember one similar to that one in my grandfathers tool box that he used with a dial indicator to check main bearing journals. Quote Link to comment Share on other sites More sharing options...
setlab Posted September 28, 2020 Share Posted September 28, 2020 That's just a homemade widget holder. Like someone above said, probably an indicator holder to tram a mil. Don't get your hopes up it might be worth a few dollars to someone, however if you need to tram in a mill you can make your on indicator holder really fast. So what you got there is a fancy piece of scrap if you don't have a mill honestly. Quote Link to comment Share on other sites More sharing options...
JHCC Posted September 28, 2020 Author Share Posted September 28, 2020 Thanks, setlab. We shall see. Frankly, anything I manage to get for it -- even if it's only a couple of bucks -- is more than I would have had before. I'll see if it sells at my asking price; if not, I'll put it on auction.
