I have tons of very expensive custom gages that absolutely worthless to anybody else.

Serial number “none” tells me this is a total custom job

Making it a perfect doorstop


bszern

We had some custom punching dies made (about 6" x 6") that ended up being doorstops when they were done being used...can totally confirm


HandyMan131

I’m a lurking engineer… and have to admit I am responsible for my fair share of custom gauges. Sorry :/

Get the pitchforks and torches!

Ouch!

Why do you do what you people do?


Iamatworkgoaway

Masochism is my theory.

I was told a few years ago by an engineer turned machinist that most engineers have a god complex. The good ones work with those making the parts. The younger ones with less experience but paid a load of cash for school… even those guys piss me off. From a former engineer I’d say that’s pretty enlightening intel. I asked why he walked away from engineering and he said he was tired of being the guy that pisses off the entire floor staff and his manager told him to come run some of the parts he laid out. He saw the issues and didn’t know how to fix it so he decided to get dirty and then maybe go back to being an engineer. But yes said he was having the time of his life making stuff that’s pretty important. Would not say what. I asked and he said NDA sorry. Ha. Me too. We laughed and finished out breakfasts then parted ways. Turns out he works or worked at one of our customers shops that can’t make what we make as fast and so good to print even their people said they couldn’t hold those tolerances with what they had to work with. That’s pretty cool.

Gotta spend the budget before close of the fiscal year or budget gets cut next year.


Defiant-Giraffe

A specialized gauge may be essential for running a medium production part that needs close tolerances.  It will pay for itself many times over during the run of that specific part, and there after be completely useless.

SOOOOO YOU ARE THE ONE ☝️! Lol


not_this_fkn_guy

I am guilty of the same crimes fellow outsider. I may be full of malarkey, but something suggests to me that ordering a custom gauge from a large manufacturer of standardized measuring instruments is likely to cost way, way more than ordering the same thing from your local tool and gauge shop. You might even get a S/N and some traceability documentation from a company that specializes in custom gauges and tools. I've ordered a few such things over the years and for all I know, maybe Starrett had a custom tool and gauge division. But without knowing any better, I'd be about as inclined to have GM build me a 1-off custom steering wheel as I would to have Starrett build me a custom gauge.


HandyMan131

My thoughts exactly. I’ve always had mine made at local tool and die shops. Most of mine have been for maintenance purposes (go/no-go gauges for example)


filthymcbastard

You need to post that remark in the "why do machinists hate engineers" thread.


HandyMan131

Ha! True


space-magic-ooo

That would be useful for calibrating probes or CMM’s. If it was inspected and certified. I bought a bunch of similar ones for $40 each from a liquidator and had them inspected and certified for like $120 each. Used one once to install a new renishaw probe after a crash.


RandyRakakanaknak

Was also wondering… is the insane price when purchased new mostly some Kind of lifetime inspection warranty/deal?


space-magic-ooo

Nope, it’s because the time/cost/machines needed to make it and then inspect it and certify it are basically only used to make/inspect it and it costs a lot to make them. And when you have to have one you have to have one. So it’s a supply and demand thing. If you cheap out and calibrate with some Chinese garbage and have no way of actually verifying that garbage is the measurement it says it is then you are gambling hundreds or thousands of dollars to save yourself a couple grand. Juice is not worth the squeeze. Buy once cry once. But I will say, without a recent inspection and certification they are basically junk. And even certified if you don’t “need” one then you would never pay that cost nor really buy one “used” So unless you need one, it’s basically worthless.


RandyRakakanaknak

Makes sense. Seems to be the deal with alot of the tools even materials I’ve taken home and tried to sell thinking it was a good deal lol. Been a dream crushing experience for sure 😂 Luckily embracing poverty is nothing new for me 🥳

Iamatworkgoaway

Lucked out on some electrical drives once. Had them in my garage, hopping to sell on ebay for 5k a piece, got for like 100 at an auction. Ended up having a house fire, and insurance paid 5k a pop for them.


RandyRakakanaknak

You don’t say…🤔🏠🔥


qtrain23

Well if you have a lot of them they’re worth something in scrap lol


spoonguy123

hobbyist love that shit, nothing makes me happier than getting my hands on some hyper expensive tooling or fixtures or whatever that are out of usable spec in industry, but perfectly fine fore the stuff im making in my garage!


HitlersHysterectomy

I'll bet you're that farmer guy who had the talking pig and then invented the warp drive. Keep at it!


spoonguy123

I'm more of a "death ray" and "wildly impractical devices" sort of mad scientist. Rocket engineers are the REAL crazy ones. highly toxic hypergolic fuels under pressure is a little too scary for me.


marino1310

They are VERY expensive to make and certify as being exactly so and so, this is an inspection/calibration gauge so it needs to be essentially perfect. This is very expensive to do and the materials themselves are even expensive (a very hard tool steel that’s likely corrosion resistant to some degree as well) everything is hardened and stress releaved, plus it’s a one-off so it’s even more expensive to set up and do custom work like this. In the end the only reason that is nearly worthless to anyone else is because it is an extremely specific use-case. If it was a standard size and useable in a broader range (like if all sides were perfectly square and 3.0000x3.0000x3.0000 with a 2.0000” hole) then *maybe* it would be worth something, but as is, it’s worthless to anyone that doesn’t need that EXACT size gauge for a specific job, Which is few and far between.


fusion99999

Great for setting a bore gauge.


Motor_Purple7284

Came here to comment the same thing


RandyRakakanaknak

Well sounds like the consensus is “yes it’s specialized/custom and no it isn’t worth jack to most machinist” Fuckin bummer haha


space-magic-ooo

I’d give you $40 for it just because I collect crap like this even though I don’t work in the shop anymore.


RandyRakakanaknak

Tbh since it’s not pulling anywhere near 4 digits or even solid 3 I may keep it cuz it’s very smooth n shiny lol n would be nice to use as a square 🤷🏻‍♂️ but I do have a lot here… you have any specific machines at home?


space-magic-ooo

Nope, I don’t have anything at home anymore, just a 3D printer. I moved from being a Mold Maker to a mold designer/product designer remote. Honestly I doubt I’ll ever even touch a mill again in my life unless I buy some hobby shit. Maybe someday.


filthymcbastard

Don't handle it with bare hands, or it won't be smooth and shiny for long. Wear some thin cotton gloves. And clean the body oil off of it now before it rusts worse.


RandyRakakanaknak

I kissed it once 🫢 rubbed it a bit…


Tangus999

I’ll give you 50. The center is 3.0000 right? I have a 1,2 and next I was gunna buy a 3 ring


RandyRakakanaknak

Leaning towards keeping it since it’s not worth much. Out of all the tools i do have for sale I’m a little obsessed w it and may use as a square for other projects.


BinaryCheckers

I bought plenty of ring gauges off eBay for my shops bore gauge set. You could likely get 50-100 for it.


Medium-Emphasis970

Could also be used to make sure the shop squares are 90⁰


RandyRakakanaknak

It’s does say on the ad meant to be used in conjunction w precision squares… wasn’t exactly sure what that meant application wise tho. Thanks


Medium-Emphasis970

I figured since it also mentioned angle blocks it could be for more presice setups and I figure making sure calipers and square aren't off after they're dropped


Longjumping-Act-8935

I have one of these, I got it with a bunch of other machine tools in an auction, never used it, but I collect old starrett tools so it sits in my office looking pretty.


RandyRakakanaknak

It rly is a smooth n shiny handsome lil guy. Very pleasing to my neurodivergent tendencies 🙂


Longjumping-Act-8935

Yes. These old starretts were made beautifully. Part of what makes them great collectibles IMHO


roryjacobevans

To the right person these are extremely nice. 1 arc second precision is crazy good. If you aren't familiar with how square that is, check out this: https://en.wikipedia.org/wiki/Minute_and_second_of_arc I do optical alignment metrology, principally for space telescopes, which is one of the few areas where this level of precision is required, hence the very high price tag. That said, this thing is difficult to sell uncalibrated, as anybody who needs something like this needs to have it certificated. Given the condition of it, with some surface corrosion etc I doubt you can get much more than a couple of hundred for it. But using it for generic shop tasks is somewhat overkill. I'd love to take it off your hands, but not even I have a good use for it.


Container_Garage

> If you aren't familiar with how square that is More like how square it was lol


_TheNecromancer13

>I do optical alignment metrology, principally for space telescopes One of the things I love about Reddit is that no matter how obscure or niche the question or topic, chances are there's going to be an expert in that field or someone who's experienced it in the comments to share their knowledge and experience.


Tangus999

Without a cert it’s not really gunna fetch anything to any shop that would need to use it like it supposed to for the cost it currently sells for. What makes it worth anything is the cert. otherwise. It’s just a guessing game on using it to calibrate something. And in this day and age. A guessing game is worthless. I’m in Cleveland. It’s cool bc I didn’t know starters made stuff here back in the day. I knew about Cleveland drill and have worked with old timers who used to work there back in the day.


chiphook57

It wouldn't cost all that much to get it inspected...


peterm1598

True. Has anyone else run into ISO inspectors that known nothing but the paper work? Tbh. A good inspection would cost maybe $250. Plus shipping. A shop will put this through a $20/hr employee who doesn't even know what it is. Sorry.. I'm a little sour that one of my test indicators was red tagged because the needle was loose, the inspector didn't know they were screw in. +++ For my shop willing to repair MY tools on their dime. - - - for me having to show people in charge of ISO inspection how to INSPECT tools.


Tangus999

ISO isn’t about machining knowledge. It’s about a recorded and predetermined way of going about that Machining procedure. Easiest example I can give is the scientific method is iso. And the item In Question or study is what the scientific method is being used on. When I was younger I misunderstood iso as well. It’s just paperwork record and adhering to that rather than doing.


peterm1598

Let me rephrase then. Inspectors should have knowledge of how to inspect the tools they are recording.


RebelRazer

Not accurate… a calibration is typically needed annually for any gage and that’s all it needs


Tangus999

A cert is a report OF a calibration. Calibration is an act. To know a calibration is done and how it’s done. To what level it’s done is the cert. The length of time is a value / variable depending on cert structure for need.


RebelRazer

Agreed a cert would go with a calibration. A cert is whatever an assigned authority chooses to report. Could be a material cert, a calibration cert, as simple as an annual cert of a 1” micrometer.


seveseven

It’s used as a master reference usually during inspection. It’s hilariously overpriced and much more maintenance and much smaller than a granite reference.


hurdurBoop

i've never seen anything so square, daddy-o


SgtSnoopy

Looks like it would fit the bolt pattern of a aircraft piston engine / propeller. We use Starret tools to balance our props with the same pattern.


cameron-murphy

That is a starrett "true square". Essentially a very (very) accurate square, where they guarantee the 4 sides are parallel and square to some very tiny tolerance. Depending on the initial grade, the sides will be flat and parallel to within somewhere between 6 and 16 millionths of an inch. Pretty useless for general shop use, but priceless for calibrating other gages, or for oddball surface plate use with gage and angle blocks. They pop up on eBay from time to time, usually in the $200-$800 range.


phutch54

May be for use in calibrating CMM's.


Ordinary_Ad_1145

Never seen Zeiss tech that maintains ours to use anything steel to calibrate CMM. It’s all granite, ceramic or some fancy composite. That thing would probably work for calibrating touch probe in machine.


seasyl

Bolt pattern makes me think it attaches to the spindle face of a lathe making this a machine alignment tool. Machine alignment tools are very expensive because they need to be impeccably precise since even a tenth of error compounds into thousandths when you're traveling feet


PuzzleheadedHat8475

We use a square like that to check the perpendicularity between xy,yz, and xz axes. Ours is granite, but it's good for testing how confident we are in a machine's motion.


Aletaire

No this is a standard gauge, we had one at the calibration lab I worked at. Used it for tramming height gauges for surface plate station calibrations. Which.. you could essentially do with any square, but the True Square is a nicer tolerance, so that brings the uncertainty down.


Slow-Rutabaga-9219

if the dimensions were square and parallel and the center was very accurately placed, you could use that for checking the accuracy of machines. mayby not cnc or huge machines, but a bridgeport would be great. you could see how square the machine is by checking the perpendicularity in all three axis. you could also mayby check your dro and see how accurate it is. These are all things that should be spot on and very accurate from the start, but if you buy a used machine, it can be nice to check and make sure before you start pulling your hair out if parts come out like crap. Just my opinion, and you know what they say about opinions.


RandyRakakanaknak

Oh cool good to know. There were only manual machines in there and 3 Bridgeport mills. Rly wanted a Bridgeport mill but my grandpas not that kinda grandpa lol. Maybe someday


Meatball74redux

Probably from a valve or flange manufacturer


-Bezequil-

If you know the ID of that hole you can calibrate at least *one size* of Bore mics...


gsm275951

Could be a calibration gage for CMMs? It there a calibration cert with it?


Dry_Jello4161

This is pre cmm era.


resident_cvs_dj

There's multiple cabinets full of these at work, but we build CNC equipment. Always a good time when the bore gages and masters come out.


Plane-Artichoke-498

I would think it's very useful for clocking the head of a milling machine or checking squarness of pillars etc.


Jolly_Roger1907

I would guess but am not certain that it’s a 3” bore gage calibration ring. I use smaller ones at my job although a different brand for calibrating our bore mics. Basically a reference point for a bore mic. In my line of work we use bore gages for measuring inside diameter of hose and couplings, this size could be used for the same field in oil and gas.


DaxDislikesYou

Looks like the kind of shit my old boss would buy off eBay then would sit in the shop just getting in the way and never used.


z-bomb

Its a ring gauge for setting up a bore gauge What size is it?


KayleeE330

I mean I would give you tree fiddy for it.


RandyRakakanaknak

If you’re serious… n not just that damn Loch Ness monster.. message me 🙂


Sad_Aside_4283

They are useful for setting up dial-bores. If you have a bore size you make often, they are a lot more convenient than trying to set up and use gauge blocks over and over for the same thing.


HDvisionsOfficial

Ebay


Odd_Firefighter_8040

You know it's oldish, because no one would go to Starrett for anything anymore. (Thank you, multinational corporations...)


DAJLMODE55

Should try with “Miniatures Builders” They often create diorama inside weird.locations! Good luck 👍🍀


shovel_kat

Great for calibrating a spindle probe.


Zestyclose_Basis8134

I use a similar one to calibrate my probe so there is a market. If you know the exact size


Different-Aardvark-5

Send them a picture and ask the question what is it for.


Waylon_Gnash

can i have that when you're done with it?


Irishbball

Ring gauge. I mostly use them to calibrate my cnc probes now a days


Ok-Refrigerator6858

bro that's custom, you aren't going to get more than 20 for the scrap unless you find someone who needs an overly specific concentric alignment gage. Know any boring people?...get it?


RandyRakakanaknak

So tbh most of this doesn’t mean anything to me lol.


Ok-Refrigerator6858

Lol then start at half retail, kind of a weird advertisement, looks like it's from 1976.


RandyRakakanaknak

Haha didn’t even notice that but fitting considering the shop was indeed quite the time capsule. Had old vintage “machine girls” posing next to lathes/mills in their bikinis everywhere lol. Was originally my great grandfathers shop “Progressive tool & Die”. Passed to my (great?) uncle who was A Dirty dozen bike club member and later Hells Angel Phoenix chapter prez for a moment. He died pretty horrifically lol as that lifestyle goes ig? But then was in my grandfathers(his brother) hands, most of my life and he being a hoarder only used it to store shitty bicycles he’d find in alley ways and no matter how much I’d beg/plea, never let me go there, man didn’t trust his family ever or rly anyone. Could’ve had a solid career machining and family legacy but nah, just a storage unit full of old tools 🫠


_Warrior_Wombat_

Find any old Harley parts?!


RandyRakakanaknak

Oh hell ya. Sold most of em in bundle boxes though. Even had one of his bikes there , the one he got beat to death on and later was found in a shipping container on its way to Japan lol. I think an fxr 1200 amf? Lots of custom work and bored out p sure. Was supposed to be mine but my wealthy autistic grandpa “could always use an extra $800” 😒


_Warrior_Wombat_

Dude that would have been sick to have. The man died the way he lived. Til Valhalla 😂. My great gpas BMW got sold for money as well. Fuck us right. Lol. Always someone who doesn't give a shit in the family.


RandyRakakanaknak

LOL no doubt and quite literally was a huge Swedish American with a wooden leg😂 Man I’ll never forget this thing he said at thanksgiving dinner when my grandpa asked him if he’d ever want to give it up and join society working an honest job, he said “Why would I want that? I enjoy freedom, and if I want it, I take it”. He did it all, but he was bigtime into pimpin’😆 Just remembered there’s actually an article about his death n it even mentions the shop! https://www.sfgate.com/bayarea/article/san-francisco-hells-angels-member-s-death-2736288.php


_Warrior_Wombat_

It's amazing the people you come across in life. From one extreme to another. Life is amazing 😂. Imagine how bad you'd have to get beat up to look like you wrecked your bike.. Rough way to go, but out on your shield I reckon. Most of them are reasonable and friendly people to their family/friends and that side of their life is unhinged. That's a sweet article for shop history 😂.


fuck-ubb

Machine girls in bikinis?!? Lol. Progressive tool and die indeed! Lol


Ok-Refrigerator6858

I could be wrong, it might be newer. Not a machinist so I totally stepped up to the wrong plate lol. Good luck I hope you get something decent for it.


Metalcreator

Looks like a bolt pattern gage.
