Somewhere in the world are a pair of these micrometers (along with many, many others) with my first initial and last name hand engraved on them. I'd still like to have them back.
I know that feeling.
@@jczeigler I gave away all of my machinist hand tools, measuring equipment, roller cabinet and top chest to a younger man who used to work for me. He needed to support a young family and was offered a job as a machinist in a shop where no tools were supplied, but on the condition that he provide his own tools. I lost touch with him as he moved away some years later. I hope those tools are still serving him well.
Lots of "unloosening" love it. Edit: lol I just learned something today. I always thought you said "unloosen" for humor, but I looked it up and the Internet says unloosen is a greater degree of loosen. Like loosen is to make less tight, whereas unloosen is to free off completely. I never knew.
Shhhh. Don't tell anyone its a real word. I have too much fun watching the english experts get upset. :)
@joepie221 I won't tell a soul, I feel so powerful now with this new found knowledge . Muahaha
@@joepie221 LOL.
I've had a Unimike for more than 40 years. Still fin it handy!
"You know you're getting close when your nuts fall off." I hope you don't mind if I borrow that line.🤣
I ran across, and immediately purchased the Uni-mic on an EBay sale, it’s very handy for some situations. This was before every tool that was in Dads or Grandpas tool box became vintage and tripled in price. The Shars tools have improved in quality over the past 15 years. I bought a set of thread NICS that cover the range I frequently work with, easier than holding wires and much easier than finding one that sneaks into the chip pan.
I have had a Starrett multi anvil mic in my tool box for almost 20 years. Extremely handy!
Thanks for all-out videos Joe. I've had this mic for years and never thought of using it as a positive depth mic! Thanks again.
Got my Starrett #225 multi mic in '79 or '80. It has been a fine and useful tool. I've even made a few one-off anvils and a stand for tricky jobs.
Great video. Of all the toolbox queen tools I've ever bought, you nailed two of the most useful purchases anyone in the trade could ever make. Uni-mic is right behind my 0-1" standard mic in daily use. Blade mic has an additional use, as a metallic cartridge reloader, measuring case head expansion on unfired brass(an indirect form of measuring pressure)while working up safe reloads. Measuring case head expansion must be done over the solid part of the case. Standard anvils often extend to the brass case wall, giving false readings. This is a tried & true method of verification. If the solid case head( on new brass) does not expand after firing, you can be very certain that your handloads are within safe pressure limits.
Nice video! I picked up a Mitutoyo Uni-Mike (used) a few years ago and I found another great accessory: It's a round base around 2" in diameter that bolts onto the anvil end and turns the mic into a stand up micrometer. You would think this is just another height gage/depth mic but try using it with thread wires! It is just excellent for thread wires! Put the two wires on the big base and lay the thread on them, then add the top single wire and you are measuring easily and accurately over wires. One more tip: every time you change the anvil, you should check the zero and adjust as needed. The Mit. instructions say to do this and in my experience there are a few tenths to a thou to adjust out.
Thanks Joe, and thanks for the heads up on Model Engineering Adventures, I subscribed right away. Slightly off topic, but I'll chance it: There was a plastics molding firm in New Zealand that had their logo in the foyer... it featured a thirty-six inch micrometer around a tiny micrometer, with the slogan "NO JOB TOO BIG - NO JOB TOO SMALL". (I think that's right). Apparently an engineering supply company had placed an order for thirty 6" micrometers. When the order arrived, all that was in it was one thirty-six inch micrometer! Returning it proved too complicated, so they gifted it to the owner of the plastics firm as a novelty. Ouch! 🥴
Thats a big mic.
The Mitutoyo is a dandy - very versatile. Thank you for presenting it!
Yep! Mine is a Starrett. Probably had it 40yrs. Don't use it all that often, but for some things, tube or bearing wall thickness, it's indispensable! Blade mics, use them for measuring frame and slide rails on pistols.
Mitutoyo "Uni-Mike" has been around for decades, they were made in standard thimble, rolling mechanical digital, electronic digital in various Mitutoyo generations of electronics. Extremely versatile in many ways. The electronic/digital versions offers all the features of electronic/digital micrometers from instant inch to metric conversion, hold, absolute/incremental/ zero adding more versatility and capabilities to the Uni-Mike than the traditional thimble micrometer. Solves measurement problems that can be difficult otherwise..
As a metrology engineer who got started in mfg as a grinding tech, I love all the weird, niche tools I've used to measure things, but my favorite will always be the "indicating micrometers" I used at my first job to check journal bearing diameters. Something sooooo satisfying about that little needle snapping back to 0 repeatedly on a perfectly wrung gauge block stack. 😍
We used to use those multi-anvil micrometers with a pin in them to measure the location of a hole to an edge.
Hi Joe, very useful and i will look at your new channel. I took the chance to visit the Mitutoya museum in Kawasaki when holidaying in Japan last month and saw the whole range of equipment and engineering development over time from 1935 to where it is today and the beliefs of first president Yehan Numata (very clever man) - it was facinating! might even make a video of it ; )
I have a starret unimic. Didn't know about the height gauge use. Thanks.
Pretty cool micrometer, usually I have had to use a precision pin to measure the inside of a cylinder or such like. What caught my eye in the video though, is your Fadel mill. Very nice machine. The first CNC I ever ran. Good stuff as always. 👍
Yes, both of those mics have been on my want list for years. I use my calipers 😒in place of those unfortunately. Thanks Joe
I was a journeyman machinist for 40yrs and used both of those mics, brings back memories.
Yes, Joe, I still have my miltutoya mini mic. Used it a lot when I was working at crower Cams
Seen them? The boss keeps them in his office enshrined in their special cases. For measuring things like the thickness of plating on metal to determine the correct acids and concentration and so forth. I'm usually only allowed to breathe on them.
@Joe Pie The pin mic converted to height gauge is definitely going into my bag of tricks.
The height gage feature is the coolest cutest thing I've seen in a long time. I love it!!!
I used a uni with a wedge when I was doing medical production
Oh great! Now I have to start fantasizing about getting these too! The tools list I lust over just gets longer and longer. 😂
You have a lot of company there my friend.
Turn it into a Christmas list once a year. :)
@@joepie221 Chuckle!
Joe - I have both of those by Starrett. Great little mic's when you need to do some tricky measurements. I also have the mic stand for all the small Starrett micrometers, both the original round base and the newer square base. I believe Starrett had the original issue on the #220 Mul-T-Anvil Micrometer as it first appeared in the 1st Edition of the #27 catalog in 1955. The #486 Blade Type Micrometer first appeared in the 3rd Edition of the #27 Catalog in 1962 and therefore I believe that also pre-dates Mitutoyo's version.
There are some things in machining that I love for no real rational reasons that I can point to. The anvil mic is one of those. Another is hardened dowel pins. I find the mass production and extreme precision to just be cool.
The advent of mass produced precision products- the dollar watch, model T car, accessible radio sets and many other things is as much a part of the progress of democracy (Or extending equality) as overtly political acts like extending the franchise. Or so say I😊
Thanks for the heads up for the Model Engineering Adventures. I subbed, looks like they're up to nearly 2k subscribers now, probably n thanks to your shoutout.
That is definitely thanks to Joe
Chuck Bommarito at the Outside Screwball channel did the same thing for me years ago. Then Adam Savage called me out as his favorite KZhead machinist. I was happy to do it for you.
Great Joe! There goes [another] $200 on the Mitutoyo 117-107! : ) Mitutoyo is my go-to for micrometers; I have a fairly extensive collection of Mity Thread Micrometers - don't use them often, but for a super-precise job I wouldn't use anything else! Now I "need" a 117-107!
I am always proud to use my thread mic from Mit. Quality everything.
Used mine with the pin all the time at the last shop I worked for. Super handy. Worth every penny I paid for the mitutoyo. I love that tool.
good video Mr Joe Pie..thanks for your time
Yup, I have one I ended up inheriting my Grandfather's Starrett 2 inch multi-anvil mic along with some of his other Metrology equipment, and it's one of my favorite mics. 👍👍
I have the multi anvil mic. It's a life saver in certain instances.
Instead of the Mitutoyo , I have the equivalent , a starrett #220 , thanks for showing me another way to use it !!
unloosen good to hear it again Joe :)
Handy micrometers those. The most unusual micrometer I have come across is a Braille micrometer, no graduations just raised bumps on the thimble so that a blind person can read by feel. Would like one of those for my collection one day.
The only specialty mike I have is a 3 pin thread mike I used twice 35 years ago, LOL Last time I looked at it the pins were all rusty. It's a Mit so they are likely still available. These are great my friend. If I hadn't retired I could likely use them. Thanks Joe.
Great mic's Joe. Luv you brother!
Used the Mititoyo quite often. Very handy.
👍 thanks for the tips!
I have the same ones and in my precious employer I had many hours on those tools.
I have a feeling that auctions for these instruments on Ebay are about to get really popular and more expensive.
Yes and bunch sellers calling a regular micrometer a blade micrometer so watch out for the crooks!!!
The first one is new to me, the second I've seen - I own the regular Mitutoyo micrometer, and I love it :) Thanks! Awesome shop gem! :)
We used these micro meters in 1970s. We referred to them as a step mic, because that is usually what we measured in tool and die making
thank you so much Joe, as always , good stuff.....helps me unloosen up after a long day at work....
Glad to hear it!
I have both a 0-1 and 1-2" Mitutoyo uni mics. Very handy.
I've always chuckled at Joe's sound effects, there's no way I could interpret that into the comments 😂 otherwise I'd be making the whistling slide/movement noise for inserting my comment here.
Good mics. There are plenty in stock in the Mitutoyo Aurora office in case anyone wants one.
Some cool variants here that i mever knew existed. Thanks for showing them and why they exist. Very cool.
You bet!
Thanks again Joe
Completely off topic, but that shot of your Fadal CNC in front of the roll-up door reminds me that I’d be VERY interested in your thoughts on shop layout and electric & air. Some guy I know with two thumbs just got himself a new shop and can’t make up his mind.
Hello, Mr. Pyzinksky Been a fan of your channel for a solid 2 years or so. I go to school/work with the Advanced Manufacturing department at a community college here in Washington State. I recommend your videos to all the students who are first starting out (everyone else is already a fan !!!). Not sure if you can keep up with reading all these comments, but I had a slight dilemma and I thought no better person to ask then the man himself: I am machining a bell out of 4140 as a gift for the shop manager (think - lunch bell). It's about 5.5 inches at the mouth. The profile came out great, but I had very little time during spring break when I could work on it. After the students returned, I no longer had access to a CNC lathe. I decided that I would remove most of the material from the inside so I could reduce the cycle time on the boring operation and hopefully find a chance to sneak in and run the ID. Well, I got a little too aggressive with stock removal and made a nice little dent in the OD. I still have enough material to run the profile again. But since I have already removed the material I was holding on to initially, I've had to devise a way to hold the thing with the proper orientation to re-turn the profile. So far, I made a rod and threaded about 2 inches on each end. Then I made a larger plug for the bottom, which is basically a cylinder with straight sides and a taper near the end and a smaller plug for the top which is more of a cone shape. I figure with the tapers facing inward and the shaft through the center, the jig would be self-centering and then I could grab the flat part of the larger plug. Am I on the right track? I havn't tried to put it back in the machine yet as I am concerned the thing might unscrew itself and come apart in the machine... Any suggestions as to how one might go about re-chucking something like this? Keep being awesome - you're killin it, -J
You may consider abandoning the initial approach and flip the part around. Machine a stepped plug that stays in the chuck that you can place the bell over and drive it with pressure from the tail stock. If you keep your depth of cut light to repair the dent, pressure turning this way should work perfectly. Thats probably the way I'd approach the repair. Thanks for your support and for directing your students my way. Much appreciated.
Used my Starrett Multi-Anvil mic today with a 3mm pin.
Thanks Joe i have some shopping to do lol... Joe Nj misses you lol
Very Nice instrument . Best regards .
Those multi anvil mics are really versatile👌 I confess to having a weakness/fetish for micrometers.....the more variants in my metrology collection the better
I have this same affliction myself.
Clever and useful micrometers. I have had a starrett blade Mike for many years. Great video and thanks for the link. I also enjoy Mr Crispin.
Mr. Crispin is a very talented young man. I enjoy his channel as well.
A friend gave me a set of Mitutoyo micrometers that,on first glance,looked like a 0-1" thread pitch micrometer.When I looked up the Mitutoyo part number, I found that they are rivet height micrometers. I never heard of such a thing.
Great little mikes. Nice shout out to Andrew's channel. I came across it on Keith Appleton's channel some months back.
Michell's personality is a breath of fresh air. I had to hit the sub button. I hope the shout out really helps them.
Hi, Joe! I’m happy (ashamed?) to say that I have Starrett 220FL-1 & 220 FL-2 (0 - 1” & 1 - 2”) “Mul-T-Anvil” Mics with flat, pin & vee anvils and a Mitutoyo 0 - 1” Blade Mic in my treasure chests. I also have 0 - 1” & 1 - 2” Disc (Gear Tooth Tangent) Mics and a 0 - 1” Pointed Anvil Mic (looks like a thread Mic, but both the anvil and spindle are “pointy”). I know, it’s a sickness, but I have used all of them at one time or another when nothing else would do the job. [Also have some custom micrometers I have picked up along the way: no idea what special job they were for - and my contact at Starrett, which is where the frame on one of them started life, is also stumped - but interesting tools never the less] Best regards & stay safe, Charlie
Cool, especially the first one.
I do watch model engineering adventures. Nice micrometers for when you need them.
Nice tools.... I noted that Shars has a version of the Mitutoyo mic at 1/2 the cost.
I don't have much need to measure tube wall thickness but not much need you can read as I did have at least one need and I bought an inexpensive Anytime Tools mic off Amazon for around $50 and it is a surprisingly nice little micrometer for the price and as it was likely a one or two time use I could not go wrong. It's just a wall thickness mic as it does not have interchangeable anvils. It has a nice action and it spot on repeatable and measuring several of my setup blocks and Joe blocks it's spot on. Not a Mitutoyo but does not need to be for my limited use. For light duty use I'd recommend it, I'm totally happy with it. I prefer a Lexis but drive a Honda, life's a bitch.
I own 4 Hondas. Not a terrible second choice. :)
Yes. I have seen micrometers like that. I have even built specialty micrometers for special jobs. But, my favorite measuring tool was always the 96" vernier caliper. What about OD thread mics?
Like the UniMic. I have been using my tube mic for years and wasn't aware these existed. Chances are it's an imperial thing only and Im from one of the metric lands. I have 3 fowler mics as well and they have been great. All imperial though.
I call them pin mics...use mine everyday. Very useful tool!!
I’ve been using these tools for over 35 years . As a mold maker there very common .
I think either Starrett or Mitutoyo had a stand for the uni-mic. I'd have to dig through some old catalogs to find it. I just stand mine on a gage block.
Jeepers, everytime I watch I learn stuff! Thanks for taking the time to make these truly GREAT video's
Thanks for watching!
I have the Starrett 220 Version of the Uni Mic. I typically use it for checking liner protrusion of Diesel engines. However the thin and round anvils are great for odd stuff that comes along. I do not have any blade mics... I have no idea why. Edit: I went over to check the model engineering adventures channel not realizing it was the same one I stumbled across and subscribed to a few days back. Yeah cool stuff over there.
That's some clever tools. Wonder how I can make the standard mM do the same. Thinking on the way....
Cheers!
Now if I could just find one of those Zeiss thread mics with the multiple anvil set...
They are a couple of interesting Micrometers.
Hi Joe.I got micrometer Nº 1.HA,HA.Great video.Thank you.
cool stuff
In Germany they are called "Bügelmessschraube"... (bügel-mess-schraube) Which in essence means "Handle(d)/Frame(d) measure-/measuring screw". It's complicated lol
I have a Starrett no 220, but I never thought of using it as a height gauge Thanks.
Is yours US or Scottish made? Mine is Scottish.
@@chrisstephens6673I guess not, mine says mfg Athol, Mass USA
Hi Joe , cant you do a short video how to read a inch micrometer for us metric guys.
I could use a metric mic lesson myself.
Yes.
At last call I think I had north of 50 mikes, a metric Mitu Uni being one.. Gets to be somewhat of an….. ah…. Obsession.
Uni-mikes are great but ever since we started using an electronic micro-hite I don't really use mine as much.
Hi again got one but mine is mills. Don't have the other.
Who invented the uni-mike? Starrett or Mitutoyo? I seem to recall they have slightly different names for them. At any rate, i have the Starrett one, and it's a nice bit of specialist kit.
Like the universality of the Mit.
Anvil mic or step mic, I have several used mine all the time...
Mitutoyo 0-1 disc mic ..handy Wish i had a pic...
I have the Moore and Wright version - handy for checking the thickness of gear teeth on small gears ( okay, I know that’s a whole other discussion ! )
What are your thoughts on the Fowler / Shars micrometers? Are they acceptable, or is it a average between a bunch of readings?
O.M.G. You still have a Fadal ! That takes me way back.
It treats me well.
I used mine to measure E ring groves.
Perfect application as well.
Got them all, all Starrett.
Im wondering if So i can get some of those cheap chinese mics and grind the anvil to a narrow line, any thoughts?
still be a cheap mic. would its base build accuracy be good enough , I use starret for the analog ones > 25 mm and mitatoyo absolute for < 25mm , blade mic yes uni mic no
@digital_harry The blade mic anvil is keyed so it doesn't rotate as it comes together. A conventional mic anvil would rotate and mess up the desired alignment.
I'll take the STARRETT 220
👍👍
Not a scratch on the Uni-mike, seems its never used there Joey.....
Its never abUSED is more like it.
@@joepie221 I got nothing, your reply was great.
I’ve never seen😊
Replace a lot of special mics
