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.

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.

I've had a Unimike for more than 40 years. Still fin it 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.

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.

I have had a Starrett multi anvil mic in my tool box for almost 20 years. Extremely handy!

[pbslab]

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.

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.

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! 🥴

The Mitutoyo is a dandy - very versatile. Thank you for presenting it!

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 satisfying about that little needle snapping back to 0 repeatedly on a perfectly wrung gauge block stack. 😍

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..

"You know you're getting close when your nuts fall off." I hope you don't mind if I borrow that line.🤣

[eddiehayes]

I have a starret unimic. Didn't know about the height gauge use. Thanks.

[gb_engineer]

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 ; )

[edsmith]

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.

[paultruesdale]

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.
👍

[bradpotter]

We used to use those multi-anvil micrometers with a pin in them to measure the location of a hole to an edge.

[TrPrecisionMachining]

good video Mr Joe Pie..thanks for your time

[joefitzgerald]

I was a journeyman machinist for 40yrs and used both of those mics, brings back memories.
