Thanks for the video!
I used it to instruct my 9 years old son on the vernier scale. Nice and clear instructions. We're back from the shop reading micrometers and calipers for the past 1/2hrs.

Verniers are old school and extremely useful. At 63, though, I have to use a magnifier to read them.

I love these videos.
Ignore all the comments from people who state that it is all wrong. All of the videos I have seen here so far and 100% correct in their application. Very little has changed in metrology since WW II, the proper way of using a tool 70 years ago is still the proper way today.

Verniers remain in use today and their principles and use are taught to student machinists. These videos are still useful, because of their high quality, to modern student (and some narrowly experienced professional) machinists.

Thank you for uploading this video. It reminds me of when I was a young machinist through the 90’s learning from men of this era.

Really enjoy these videos. I'm 74 and still try to learn something new everyday.

This film is so true and useful for an Apprentice.
Then you applied your Skills and worked different Jobs for Experience and developing your Machinist Skills.
For a Job Shop, Time was Money, every Day after Day.
When you worked in Production, same part, different day
for months and months.
Then R&D, different part, every day for days and days.
Later, if you were good, you worked as an Engineer, Pencil & Paper, until you went into Management. Same thing..."When will you finish the Project?". I enjoyed being a Machinist.

Really enjoy these videos. I'm 66 and still try to learn something new everyday. Fascinating stuff

9:12 + 3 tenths. That is one tight tolerance. Grinding, yes, turning it you gotta have a straight lathe.

Im a toolmaker, and im pretty happy we use milimeter here in Denmark, it just makes more sence, to me... its potato potato, but milimeters just seems more “clean”

[reneramirez]

Boy can I appreciate my digital Mitotoyo calipers.

The feeling when I change my mind from metric to imperial is the same as when I speak another language.

It is my opinion that you should disable comments on all of your videos. They are not meant to be open to interpretation they are meant to show us the history of this subject matter. We used to measure with cubits, which obviously isn't very accurate, but it's what happened, and it's fascinating to learn about. This is one of my favorite channels on youtube, and unlike everyone else here I will tell you to keep up the good work and ignore these armchair quarterbacks who don't understand the point of the good work you are doing preserving these videos that we would otherwise never have been able to see.

I wonder what the #3 movie was. Calipers, perhaps?

[DrLumpyDMus]

All those guys in the credits up front. They all have initials for first names. Thanks - Lumpy

Thank you for posting this. I'd long wondered about the principle of the vernier; now I think I understand it.
Is the "Tom Watson" mentioned in the credits T.J.Watson of IBM? The Studebaker surely has to be related to the car company family.

[ProfessorMAG]

Hate to break it to you, but this is NOT how to read a Vernier. In this example when the ones line up it is 1/5 of the main scale division, when the 2s lines up, it is reading 2/5 of main scale division and so forth. this training film is giving a misconception of the vernier principal.

Is good to keep this video only for posterity, which is the most important job of any museum or any teacher... but for the sake of any students who see NEVER take a micrometer off of the part and then read it... it must be read while on the part in order to ensure the accuracy of the tool if your purpose is to read the nearest one thousandth or nearest one ten thousandth of an inch... .and never rely on "feel" if you can avoid it.

This film is flawed to the bone... it is only good for the purpose of maintaining posterity; if a man like me walks up and says all the instructional videos from that era were perfect and you need to prove otherwise in order to illustrate that there is no such thing as a perfect era with nothing but perfect or great teachers and great students or any other similar.

thanks for posting this video.. but it should come with a disclaimer.... nearly as much as my posts should come with a grammar disclaimer.
