Oh no! I feel your pain.Nice Dark, I have the exact same micrometer, but sadly I recently pulled it out after sitting in a drawer for the last four years and found that a lot of the anvils were completely deteriorated and eaten beyond repair by the black foam in the case that crumbled, falling onto the mic and anvils eating the metal leaving large eaten pitted voids in the metal, it's not rust.
I’ve been meaning to make a general post about warning other MIT. tool owners (or potential buyers) to look out for this issue that seems to be fairly common in the older orange cases. It's the black open cell foam that is on the roof of the cover or the lining layer on the bottom of the case. When I have time I'll pull it out and take some pics of my interchangeable anvil; its rather sad and I'm in denial thinking it will be just fine with a little little cleaning.
Here's a pic I already had of my inside mic., luckily it doent effect performance and most of it is on the backside. I changed out the case so it's not the one in the background. I've actually come across quite of few Mit's with this issue, again sadly I myself have quite a few like this.
PS> Thats a nice Royal spindle live center you have.
There must have been something really horrendous in that foam. You‘ve got me worried now as I know I have an Etalon vernier in a case with degrading foam. I think I’ll be removing it tomorrow now.
If I could give you any advice it would be to replace that mic, whatever it costs. If you don’t, the loss will annoy you for ever! I only ever damaged one tool beyond repair and that was a dial vernier. I got pissed off every time I needed it till it was replaced!
Ah might as well add one more for today....Oops I missed a few Mondays.
4" & 6" knife straight edges.
I’ve never seen anything like that, what are these used for? I assume for checking flatness? But to what extent? Scraping?Ah might as well add one more for today....
4" & 6" knife straight edges.
edit: I mean like checking your scraping, not actually usino them to scrape with
Yes, precision straight edges are used for quick visual checks for flatness. Not necessarily for checking scraping work, they usually use bluing with surface plates methods for that.
These are knife edge but are not sharp like a knife. Just the thin edge provides less surface area contact to make it easier to see. I'll hold them up against a surface I'm chexking & hold it up to a light to see if any light passes through. The smaller one I have is black coated so it makes it even easier to see any light passing through.
I'm just a hobbyist so I don't really need these but they have came in handy a few times. Just got them cause I came across them for cheap on ebay.

I do have more modern stuff for work, but I think you all may find this interesting!
Some never used!

I have this square (10-20 years old) and the name plate has dropped off. Fortunately I found it but I would like to reattach it. What do you think, epoxy? Whatever it is needs to be robust as I use this often. Thanks!
Time for a thread revival? The end of Starrett thread reminded me.
Reading through this thread again, mainly I'm wondering what happened to @macgee ? A while back I noticed he hasn't posted in a while, sear hed just now & looks like his last post was 2 yrs ago. Anyone know what happened to him? Hope he's doing ok.
Well it ain't Mitutoyo Monday but whatever, I think I stopped posting cause whatever Mitu I have isn't all that exciting & just common. But anyways.....
My most used calipers, I really like this generation of the CoolantProof 6" so I also have back ups of these stored away which I'll probably never need in my lifetime anyway.
Yes, those are HF cases, from their older digital calipers. They changed a little at some point & the price went up. These are from when you could get them for $10 which was worth it to me just for the case, I would give the calipers away to friends or family. For frequent use I much prefer these cases than the original Mitus.
The ones I use the most for machining related have carbide jaws. I never knew these existed until I came across them on ebay. Seller did not know what they had & I got them for a great price.

Recent Mitutoyo addition to the shop.. Mitutoyo linear height gage. This one is definitely an attempt to level up without going completely overboard. From a purely height gage perspective it’s definitely a lot more tool than I need. From a somewhat of a 2D CMM like capability, this is a very small fraction of what a real CMM (coordinate measuring machine) would cost. The lower cost units are near six figures by the time they are delivered. I took advantage of a Black Friday deal. That was the thing that compelled me to go ahead and buy when I did.
I will be using it to aid in inspecting my parts. It has already helped with dialing in some toolpaths. The resolution and accuracy are impressive to say the least.
On the surface plate with the dust cover in place.
The probe is motorized. This aids in repeatable measurements. It also is why it’s like a 2D CMM. It can do bore measurements for example.
First thing I did was take a look at a threading toolpath I’m working on. I measured the height of the block and then the end of the set screw.
My 2” part is two inches! The delta is how much the set screw sits proud of the hole. Adjusted the toolpath to thread another 0.1”.
Here we see the result. YES! There are absolutely much less inspection equipment required to make these measurements. I would of course use a caliper at the machine. This was a chance to check out the new tool

I don't have much Mitutoyo stuff, but I do have this combination square and vernier caliper that I inherited from my dad. The quality of manufacture is very, very high. These saw little use and are in nearly perfect condition. I think I have the boxes somewhere, too.
From what I've been able to find, this version of the logo dates to the 1962-1965 time period.

I have a couple sets of these from a later period where they were still making them in Japan but were a different paint scheme.

My cigar box of precision measurement tools. Top is a vintage Mitutoyo 6" dial caliper (with adjustment tools) plus 1" micrometer set. Below is a new Mitutoyo 150mm dial caliper. The only way to adjust is to rotate the head til 0 hits the needle.
New as in brand new or new to you? Does the needle not land near 12 o'clock when the jaws are fully closed?
If they are not brand new never used, dial calipers can skip teeth on the rack & pinion. Can take them apart to "reset" them. But I don't own any dial calipers myself h have never done it personally.

The metric caliper is either new or NOS. It's a cheaper model off Amazon but authentic as far as I can tell. The needle does not hit straight up 12 o'clock at fully closed, it is off by maybe 1.5 to 2 degrees. So you rotate the dial to make the needle hit 0 at fully closed. I read about disassembling them but It sounds like I could easily FUNG it without absolutely knowing what I'm doing. Long Island Indicator Service indicates due to their low cost these are not worth the price to professionally calibrate, and they don't work on dial calipers anyhow. Both of mine will be far more accurate than anything I very infrequently need them for.

I have a fair bit of Mitutoyo, if I have to buy something new because I need it now it would be my first choice because of availability and price.
I buy most of mine used or NOS for cheap though.
A couple recent purchases.
Tube wall thickness micrometer, new.
O-10mm bench micrometer, quite old but in lovely condition and the box is great.

Tool ****, I have a mixture of precision tools, Mitutoyo, Starrett (English & USA), Brown & Sharpe, Moore & Wright, Helios, Mahr and more.
I'm like Darkzero and have bought a lot of tools used, some have been excellent condition but with markings, now I only buy tools with no markings. I think I've only ever bought 3 new Mitutoyo items at full retail
Anyway here is a set I am selling, I love the wood cases
If I could buy the wood cases I would buy a heap of them
The 0-2, 25-50 & 50-75 159 series mics I've had for about 40 years, the 50-75 was attacked by the deteriorating black foam and thiss annoys me so much, so I went and bought a new old stock one. I have a set of these all the way to 100mm, metric on the barrel and imperial on the digit.
This is just a small fraction of my collection.

I pulled some micrometers out of my box today and confirmed my thoughts, my thread micrometers are different to Darkzeros
It was also interesting to see the different "Mitutoyo" styles.
I have made up a set of 102 style micrometers, the 0-25 & 25-50 are 0.001mm and the 50-75 and 75-100 are 0.01mm

I have been searching for any information about the Mitutoyo 206 series micrometers, I purchased one a while ago that is nib but can't find it in any of the catalogues I've got and have found on information about them at all.
The 206-101 is the top right digital micrometer just below the two Uni-Mikes
The 206 is the same as the 106 series only it also has a digit readout

I paid £3 for this 513-984 dial Test Indicator this morning at my local small car boot sale. It appears to be unused and has all its original accessories.
Thoughts on this haul? It's not far, and I could use a depth mic, plus that giant set of calipers looks useful.

The price is very good for what is shown as long as they are legitimate Mitutoyo. My only warning here is that there were a ton of counterfeit Mitutoyo calipers out there about starting a few years ago that were selling on ebay and amazon cheap.
This is one video on helping to spot them. Just an FYI.

I've got a few Mits, I've got other brands too. The tools in my view that need the best are Mits. But, I would LOVE to have an Interapid long stylus dial test indicator. Most all top gunsmiths swear by them as the best, but the price tag to me just isn't justified. Can't remember the model, but the Mit DTI I have has is small in diameter and has a stylus about 1-1/4" long. It does what I need.
