Mitutoyo Dial Caliper

Wreck, because in this case the price difference is substantial. You DID actually read that it was GIVEN to him?

Yes I did, my reading skills are quite suitable for normal conversation, however a generally disposable inexpensive hand tool is not worth the trouble, do not get me wrong as I own some 20+ year old tools that still work very well, have a 20 year old Mits 6" caliper that I use nearly every day and it is still in excellent shape. I suppose that my point is that low dollar value tools are more expensive to fix then they are worth, I buy new ones as my employer gets well and truly ****** off when the parts return with a "Notice of Noncompliance" tag on them, these are almost always red in color (-:
 
I have been on both the receiving and giving end of NCR's and Corrective Action Reports.....so I truly know what you mean. And sometimes they are yellow, if they are reworkable, or UAI tags. That mean you don't have an outgoing or final QC stage?

So then, if you get a chip in your dial caliper rack.....give them to someone and buy yourself a new set....right? :beguiled:
Just seems you missed the price in the OP.
 
Bloody hell, a new Mitutoyo 6" dial caliper can be bought for less then $200.00, why even bother with used tools in that price range?
Hi wreck, I can see where you are coming from but being only a hobbiest (with no training in this field) I'm afraid that $200 is not considered a disposable item for me.
Also I have an electronic one (cheap) and a micrometer (cheap but accurate) and use those most of the time.
As it was given to me I just wanted to get it working correctly.
As I usually work in metric I probably will very rarely if ever use it.

That would be dishonest at best, I also enjoy receiving tools for free, have received many in the past that I do not use for a living but are well crafted or otherwise beautiful.

I simply consider sub $200.00 direct measuring tools that are damaged or inaccurate as not worth repairing, micrometers, tubular or rod bore gauges, dial bore gauges, height gauges and so on above 6" are worth repairing however.
Where I currently work we have 2 Starrett and one Mitutoyo internal rod micrometer sets from 4" to 18" which are not to be trusted at all, we do have 6-18" micrometers and gauge blocks so I can get very close. I suspect that an inside rod micrometer from 4" to 12" will be my next purchase, about $300.00 from Mitutoyo or Starrett.

I am not that keen on metrology however we do have a 96" X 48" X24" granite surface plate, the manufacturers tag says 6400 + Lbs, it is absurd.
 
Where should I send them?

I would rather give them away, with no assurance that they useful for high accuracy work then toss them in the scrap.

Well, you could send them to me. I'll pay shipping. I've already successfully restored several hopeless instruments to usefulness.
 
Wreck, I don't know too many people who actually work on the machines who trust ID mics. I have a couple of sets myself, and despite the fact that they are correct as close as I can adjust them, I still have a habit of measuring over them as though they were telescoping gages. So that's hardly uncommon.

And on your big mics, even stacking gage blocks can be suspect. The general preference is to have a one piece standard that is factory made, and having it calibrated to an actual size by an NIST lab in QC, controlled environment and used for checking the big mandrel mics. Very rarely are they as close as most people think they are. I have sets up to 24", and calibrated standards for each inch. They're not current, because I haven't needed them in a long time and to spend money on an annual cal would be ridiculous. If I need them, and I am required to back them up, I'll have the standards re-certed, but not until I can justify it. And yes, I can run my entire shop at 68°f and 50% RH, just as though it were a inspection/calibration room. I have a certified thermometer with hygrometer on the wall to prove it if I need it. NOT at the moment, thank goodness.....this broken leg is really beginning to bug me!

I think the point being made is that there are times when it is a matter of maintenance rather than actual damage. Most all dial calipers have a spring loaded pinion gear to "jump" over any trash that may (read:will eventually) get in the rack. That's why they send the little copper tool to reset it. No biggie, and no damage to the calipers at all.

I'm not picking on you, honest! :)
