Go No Go gauges....

[wantacoe]

Does anyone use them anymore? I have had some on ebag forever and no one wants them. They have had 79 views. I even added a best offer option.

It depends on what they are for? Go No Go are usually only used in industrial settings. They are usually pretty specific to the job task at hand. And they have to be certified to make sure they are within specs. So if they buy yours they are coming from an untrusted source and need to be sent out for certification.

If they're just pin gages there's no way I'd buy them second hand. It is too cheap to buy them new with a certificate of calibration.

I could use a set mosin nagant rifles.

Are you saying I am not trustworthy? LOL, I know what your mean. They did come from an industrial setting. But when we used them one of our inspectors would just mic them. I just looked at some sold ones on ebag, they seem to go anywhere from $1.00 to twelvish for .250ish sized ones. Any idea what they go for new?

mic isn't good enough for a lot of applications.

By the time they track down a used gage, and have it calibrated it doesn't make much sense. It's only 25$ to buy a new calibrated vermont gage one from McMaster.

Sorry Wantacoe, I'm sure I'm a few of those views. I've had these listed locally and nothing. I understand why. I guess that it doesn't help that most of my over 75 are unused and come with certs from the 60's. Yup, the 60's. Good luck and please PM with interest.

Squashfest81, I probably have over 200 of them. I bought them at an auction at the company I worked for. They had thousands of them and people were going crazy bidding on them. Lots of industrial people there. I thought they would be an easy sale based on how the auction went, guess I was wrong Here is a pic of one flat of them.
Funny thing though, I worked there for ten years and never saw them use one anywhere. They just bought cheap Chinese parts and slapped them together.

Was totally expecting gun gauges...!

 

[Squashfest81]

They are precision tools and obviously not cheap, but I'm thinking has almost no value second hand. I had a machinist who bought a few other tools off me. We chatted and I suggested that he bring them in to his shop as he thought that they would be interested. They would have, but mine are actually too precise, nc and nf 3 (?). At this point I'm thinking you will all see mine in the repurpose thread.
Although I still think a small machine shop would scoop these up for cheap.

There's a go, no go gauge for the swedges you make on cables that brace the wings in place on my ultralight.

I sure wouldn't trust myself to make those crimps. Too much hangs in the balance.

Yes, they are used all the time in inspection rooms, but... most of the gauges used will be custom made for a particular application!

Go/No Go thread gauges are dying out in industry because CNC machines really don't need their cut threads gauging - every one will be a coconut, as they say!

I've never used these things in my workshop at home, and I doubt anyone else does either!

i am a quality manager in an aerospace machine shop. we still use thread Go/NoGo gauges. especially the 3 series (has to do with the allowed tolerance class 3 is tightest) CNC has very little to do with the thread size by the way Dave, it is the quality of tap used. unless you thread mill them which is not dine that often on smaller holes. and no matter the quality of tap, they wear and can go bad, thus the thread gauge use. ...to the OP. you will have trouble selling them. unfortunately most shops have what they "know" they will need already. and there is no way for them to know when one will need replaced,there is no way to know when a new size/pitch will come down from customer engineering

The fact that they are just haphazardly thrown in a box, deters many buyers and rightly so. For someone that NEEDS them, they are not going to chance it or spend the time (money) to check used gauges. It's like when you see people throw otherwise good milling cutters in a box all clanging together.

As you may have gathered from other posts. A Go No Go gauge can be anything from a basic pin (what you mostly have) to a complex multi feature part. It is a just a fast, toleranced measuring tool for determining if a operation mets specs. You may be able to part them out individually, but again time vs money.
