- This episode I'm going to show you some of my Starrett vernier calipers and demonstrate how to read them. I'll take some OD measurements as well as an ID measurement and explain how to add up the lines to get the dimension measured.
This is from viewer request and I know that many of my viewers are trying to learn the fundamentals of machining and how to use the tools properly. If you have a request leave me a comment and I'll try to add that to a future episode. - Věda a technologie
I'm not a machinist, in fact, I've never set foot in a _real_ (non basement) machine shop. But i love your channel, and have always been fascinated by it. Trades were strictly frowned upon in my family growing up, so it was never really an option for me to pursue. Sitting here all day at my desk doing IT really makes me wish I'd taken up a real trade and had a useful skill.
I really like these videos because they teach me a little bit here and there about the basics. Never in any of your videos do you ever seem to be talking down to the viewer, or anyone for that matter. Makes it really easy to learn and watch. Thanks for making them.
This is such an awesome compliment, seriously.
As well, its never too late to learn these trades. People pick them up and begin doing hobby machining ALL THE TIME. Nothing stopping you, but you. :-) Check out a local community college and take a night machine shop class. Thats a good way to see if its something you enjoy or not.
+rewtuser I love hearing from viewers like yourself. So cool to hear how people in different fields of work watch my videos with interest.
Too bad your family didn't want you learning trades. Tradesmen are in dire need in this country. Skilled trade jobs are everywhere and more and more people are retiring and those positions need filled. Like Brian said, if anything take some night classes and see if you like it. I know for fact another viewer just like you quit his deck job and is now working in a machine shop because of watching my videos. Very cool!
Always been a pipe dream of mine to get a small mill and lathe and take on some little projects (look what clickspring does with his tiny little workshop setup!). Hopefully, my job (small company) gets a little less stressful over the new year and allows me to look into that.
There is a vocational school very near me that I think does training in both welding and machining, might be time to inquire about class costs.
Thanks for the reply.
Go find a small corner of the house/apartment/garage and buy a small lathe and a drill press or mill. You would be surprised at how relaxing it can be to cut a thread on a piece of rod, or making something like a pen. Plus you might find a niche item you can make money to feed the shop off of as a bonus.
Stress will eat you up.
25 odd years of sitting at a desk doing IT stuff, I bought a lathe and am learning with the help of these videos to drive it. Enjoying having dirty hands.
Thanks for the video. I have never see an explaination for a vernier in 50 thousands graduations. Those are some treasured measuring instruments you got there.
My dad tried to teach me this before and he told me exactly what you just did but I never understood it! Somehow watching this made it suddenly seem so simple! Thank you!! New sub!!
Cheers Adam. I'd learned vernier decades ago, but never needed them that precise during my working career. Useful reminder, came back to me when you showed the lines in alignment.
I thank you for doing this video. I worked in a job shop in college and the manager gave me one of the 14” Starretts as a parting gift. Just pulled it out for the first time in 43 years and needed a refresher on how to use it. Thanks to you I’m ready to go on my new welding hobby.
I love the fact that you keep tradition alive. Now everyone wants to use digital measuring tools and to that fact you had to show everyone the first measurement on a digital so that they would believe you. God bless you for keeping your father's and grandfather's craft alive. I'm sure they would be proud of you.
+Hammer0f Thor You know, I did that and didn't even realize that's why I shown the digital, but yes to verify the length. LOL! Thanks for the comments. 👍🏻
Great lesson. Having a grandad and dad as teachers was the best free education that no amount of money could ever buy a person. Thank you for sharing
Such a clear explanation Adam... well done. These shop talk videos are a great addition to your channel.
Just found my old 12in vernier caliper and watching this video reminded me how to use it, thanks great video
My very first job was in a door,window,cabinet shop, I loved it. Fast forward, I was asked to step in at a machine shop to fill in for a pattern maker who had health problems. Everyone there was more than willing to teach me their trade and in return I was more than willing to teach them mine. In that short amount of time that I was there I learned more from the machinists then I could have ever learned at any school. Great bunch or guys and girls over there. Keep up the good work and I'm looking forward to more of these videos.
Just about everything you show is the same stuff I learned as an apprentice in aerospace, some 48 years ago. I learned from some of the old time machinists before me. The tools and methods created by our predecessors, never gets old. The thing about vernier is you don't have to keep checking the calibration and zero'ing the device. If you want to see if your digital is good, use a vernier as a check.
at 68 i have now forgotten something so i can remember this. its taken all that time but now i know how to use my verniers.
You do an excellent job to make something understandable that others make overly complex with too many words.
It's been almost 40 years since I learned this skill. Thanks for the refresher! Great Vid!
You fit the part well & make an EXCELLENT instructor, like calm cool & collected on the delivery(easy to follow)! I would like to see a vid from you on how you remove, install & size a valve guide. Thanks much for taking the time for hosting these instructional vids like nothing better than experienced Americans opening the door for other Americans to both learn & better themselves in the game of life!
Thanks, i never would have known the fine reading on the calipers, always thought i knew what i was doing until someone comes around and shines some light
+G1itzik I'm glad the video could be of help.
You did a good job of explaining how to read a vernier caliper. It can be very confusing if you've never read one before. I just learned this a few weeks ago. I'm 31 and currently going back to school to become a machinist. The way you explained it, falls directly in line with how it's explained in the text book.
Thanks mr Abom for that demo. I'm a woodworker, and I've had a 7" caliper laying around in one of my drawers for years but never knew how to use it properly - I didn't know what the thumb screws were for. Mine's a 7" and a little different from the ones you demonstrate. It has two separate jaws - one for outer and one for inner measurements . It also has a lower imperial scale and an upper metric . As a woodworker, I am happy to work in Imperial or metric - although there's no getting away from the fact that metric is easier to divide into.
I see that you have a quality make there - Starret . There's nothing like using quality equipment . Just try explaining to your Wife, why the special order you made ( which will last a lifetime and possibly be handed down to a family member ) cost 4 times the price of the cheap item at the DIY store!
Excellent love showing the lock to prevent sloppiness.
Since I’m currently taking night classes at my old high school for advanced manufacturing/ cnc machining this will actually help me a lot since I’ve always had trouble reading these and micrometers. Thanks
A very clear explanation, excellent close up video backing up what you are explaining. Adam, you have a natural talent for teaching. You bring in your machining experience to illustrate your topic. I cannot help but avidly watch your videos enjoying your personality, experience and desire to help others. Excellent presentation. Thank you for what you do!
I’m a 30 year glazier but I went to school for machining and worked as a lathe hand at a metal spinner early on in my working career. I love watching your videos. It lets me brush up on and see how much I still retain. I seem to remember our shop having and old Italian engine lathe where the carriage moved opposite of what you would expect. For example you’d turn the wheel clockwise to move the carriage toward the headstock. Have you ever seen that?
Right on that’s always nice having things from family hangin out. Cool right . Tight wire readings finding center set up to find true readings. Doing reverse alignments dial indicators .
I work in wood but, essentially, our jobs are the same and much of what you teach is relevant to what I do as well. Love your channel [recent subscriber] and your ability to explain things in a way that we understand. My uncle was a machinist in the Navy (Vietnam era), he was on the USS Ajax. The dude has tried and failed to teach me how to read vernier calipers a dozen times over the years yet you managed to make it seem simple in a little over 18 minutes. Thanks and keep up the awesome work.
+EfOneAddict That's cool. When you get stumped on how to read them, you can always come back to this video now. 👍🏻
thank you for explaining this! I work at a machine shop and ive been making some hydrologic shafts the last 3 days. they measure 55 inches between the shoulders of the journals. and 57.5 overall length. I have to use a huge set of vernier calipers to measure this and I was getting along fine but knowing all this really makes me feel confident I'm spot on!
I’ve been programming/first time running on CNCs for 7 years and I’m no longer going to use the probe to quick check things Over 12” this is so much faster, I hated these before this video....perfect thanks Adam
I just started a school program for entry level machinists and this video helped me a lot with understanding vernier calipers. Thank you so much!
I'm from Britain and I use both metric and imperial, but I've never used imperial for precision measurements but I'll now give it a go with my callipers.
keep up the great work.
Many, many thanks for that clear explanation Adam, I feel much more confident reading them now.
Hey Adam, i really appreciate the care you take with those gauge blocks and with all your surfaces when you place them on metal to metal its a great muscle memory to get into the habit of. keep everything true.
Shows a true professional
Cheers Troy
Excellent training video Adam thanks for all your efforts to help us all.
Great tool video! Good to see the tools looked over as well as the projects. Great channel!! Keep em coming!!
Good Job Adam it helped me to see how important it is to have that "Touch" no mater what measuring tool your using to get that real accurate measurement. Thanks
Seven years later I'm watching this because I bought an 18" vernier caliper. Found it on the auction site for $35 and it's in new condition. They start at around $275 new and dial calipers that size are really expensive. I'm volunteering my shop and skills for a historic restoration project and found myself needing to accurately measure items between 12"-18" regularly do I could make reproductions. Having taken drafting in college (early '70s) as an elective I learned how to read the vernier on a drafting machine, I found the 1/1000th vernier pretty easy to read when taking a measurement but setting it to a precise measurement seemed to be a little more of a challenge. Then is finally clicked. Go past the inch, go past the tenths and past the .050 mark if necessary. Find the thousandths mark I need and move that mark to the right until it lines up with the first line it comes to.
Thanks abom Im just a hobby farmer and all of my digital calipers broke but I had a starrett pair of verniers that I was able to read and make the parts I needed to keep equipment in the field love your content your a very humble and an excellent teacher
Very well said and illustrated. A good refresher for me. My Machinist Father taught how to read calipers back years ago!!
thanks!!!
An excellent lesson from an excellent teacher : ) Thanks Adam !
Thank you. You explain very clearly and no nonsense!
thank you! I've got a few digital calipers and a dial that make it easy but I was given a real nice brown and Sharpe a few years back and never figured out how to use them. you are the man!
Thanks for taking the time Adam, much appreciated ;)
Thank you Abom for the instructional video. I haven't used vernier calipers in so long and a new employee ask. I pointed him to this video. Job well done.
36" Vernier's ABOM size tools. Great video Adam, keep them coming
The first precision measuring device that I ever got was a "Central" vernier caliper. That was nearly 50 years ago. I still have have it and use to on a regular basis. Great explanation Adam.
Excellent instructional video with very clear close-ups.
I'm just starting to do all this I can't thank you enough I watch your videos daily
Very good explanation Adam about the use of larger vernier calipers (especially the just touch it and the feel the touch of 180, squaring and perpendicular and getting that touch) so one can get an accurate measurement.
Very good presentation and instruction, Adam!!
Thanks Adam, I am a metric man and your explanation was so easy to understand as I always go for a digital vernier when I have to do imperial
Thank you Adam !
Your video has just taught me (finally after so many years ) how to properly place and read the vernier calipers.
In fact I will be relying more now on the analogue than the electronic ones .
Great to hear this!
Great video. I am self taught on this and I learned a lot about what I was doing wrong, Thanks Adam.
+Mike Cunningham Your welcome Mike
Great video.
Lots of folks scoff at verniers and call them 'very nears.'
They are in fact extremely accurate when used properly.
Very cool Adam. Thanks for your time.
You explained how to read them so well! Thank you!
Thank you! And it feels better when you mention your Dad and Grandad. The old timers had it going on! I was a fighter pilot all my life and am just learning how to measure with calipers, etc. This helped alot. Oh ... and now I have vernier envy as well ... lol.
I have the same Starrett 12" vernier calipers. I never knew how to correctly use the fine adjust. Thanks Adam!
I really dig the Starrett calipers. Most folks don't know how to read them.. Great video!!
I have watched a lot of your machine shop stuff. This one is exactly what I have been trying to learn. You make it so simple and easy to understand. Thank You so much. Yes I am one that has to buy the cheap stuff.
Thanks for the trip down memory lane
Thanks Adam...you're always adding to my 'wish list' of tools that I'm jonesing to buy, LOL! These shop talk videos are some really useful info, and I just imagine how special they will be in 50 years time to teach the history of the craft. Aloha...Chuck
thanks adom been a real long time since i used vernier calipers
Thanks Adam, Just got a nice pair of Starrett 14" Calipers from Jack and your video surely answered my questions about using them accurately.
I use your granddad's technique all the time. When I need to turn a small part I set the calipers for the largest diameter on the part, then lock the jaws and use them as a go-nogo gauge to hunt through the material rack looking for a piece where the jaws won't quite go over.
I always wondered how you read a vernier and now I can see how. Not saying I could pick one up and read it, but it sure gives me a better idea of how to.
Adam, A very good in-depth video and thank you so much.
Beautiful 36" tool makes my heart beat faster. They are heavy because of all the gold they cost. Thank you Adam. I would be willing to bet that there have been more things build in the world using vernier scales then the newer stuff!
+dejanira2 You know you make a good point! 👍🏻
dejanira2 n
A quick google will show an invention date of 1631. ;}
A good job explaining as usual. Thanks for sharing this information with us.
Thanks Adam for this great information. I’ve always used a digital vernier calliper because I didn’t know how to read a normal vernier, this video has helped me a lot thanks John
Excellent. Bought a Starrett 14-1/2 Master vernier caliper recently. Thank you.
Brings back memories of the old slide rule days before calculators.
love those calipers way more accurate and reliable. keep up the great videos!!
Straining your eyes trying to see which line out of fifty, lines up perfectly is a lot easier once you realize that they go from being off to the left to being off to the right as you go across the scale. Sometimes looking at the ones on either side helps you decide which one is closer.
Yeah I noticed that to
Another great video Adam! I really like the shop talk videos. Keep them coming.
Gary
good stuff Adam, great to see the big callipers out,keep em comin
Thanks for sharing. Reading Verniers have always been a struggle for me, I don’t use them much.
Great explanation. I learned how to use these in high school auto shop. We learned how to use both dial and vernier but for the most part we only got to use vernier. Because of knowing how to use these the first time I ever picked up a tenth mic I knew how to read it with no further instruction.
I still use vernier calipers in my racing endeavors because they are more durable while in the pits.
Awesome! I think anyone having to read precision tools should learn how to ready these types of calipers. You should be versatile with the shop metrology.
Very simply, thank you! You broke it down very clear and nicely explained your methods.
I very recently was given the task of calibration certification for my shop, never knowing how to read dials, vernier, height, or micros. Your Shop Talk 18 on how to clean and rest a dial was very helpful and this video made it click for me on understanding how a vernier is read. *Liked and subscribed!
Love the videos Adam, I'm a CNC machinist but learnt the skill on manual machines. Watching your videos helps keep my memory fresh so I don't forget manual work.
100k subscribers for 36th birthday would be awesome :)
Not quite there but very close.
I thank you for this video. This why I watch CZcams. You did a great job teaching.
Adam
nice video Its funny what comments really stay with you. And the joy of picking up a tool that was given to you and who it reminds you of.
Very nicely done Adam, I still have to go to the 42" calipers from time to time, the only thing now is I use a small magnifying glass to read the Vernier. As you mentioned before with the rite feel they are very accurate.
Thank you so much Adam, I never realized how accurate these calipers could be. They might not be as fast as a dial or digital but they don't get messed up unless they get bent.
+m2hmghb These calipers are pretty tough. They can take some abuse but as with any, care should be used when handling them. I like them better hen digital for the big measurement because of the fine adjust.
Awesome video. If you can find a ring gauge with the measurement on it. You can quickly learn the feel of the telescoping gauges, mics and vernier calipers. Thanks for the wonderful videos and sharing you knowledge and experiences.
Nicely explained. Your teaching skills has improved from your earlier videos. I look forward to upcoming vids.
Perfect! Your video gave me an idea... I took a pic of the reading and zoomed in. Made it much easier to read. Thanks Adam!
This reminded me of some old timers that use a magnifying glass to look at their readings all the time (they refuse to wear reading glasses). They always have trouble finding it in the shop, but they all have iPhones. iOS has a cool magnifier app in it that actually works pretty good and they were stoked when I told them about it, lol.
I just realized your reply was 4 years ago! Haha 😂
I was taught to take a good bite with caliper and angle it at about 30-45° against the piece axis. That way, you're preventing an "overbite" in either axial or radial plane.
great reference video adam thanks for sharing
Adam those 36" verniers are nice, but many years I worked at a machine shop that had a 10' vernier. It was used for building checking fixture bases for the auto industry whoooo haaa it was a monster. Still loving you show keep it coming.
Phhwoaaaah!!!!! Those 36" calipers are awesome!
My father taught me how to read calipers when i was small, he gave me a heap of bicycle spokes and i sorted them by thickness. It was more fun for me, than some video game.
Great info, keep the videos coming
you made the process seem so simple, thanks!
Ok, that is amazing. Whoever came up with that idea (I assume Vernier) was a genius. Thanks for the lesson!
The 36 in. Starrett is like new, what a beautiful instrument. The moral of the story is .... take care of your tools and they take care of you. 😊
Extremely interesting. Thank you.
Thanks for a very clear video with very clear composing of the camera vs the measurements and #s. Its good to zoom into the #s, picture means thousand word.
Appreciate it.
Awesome video Adam.... You are a good teacher......👏
OUTSTANDING!! THANK YOU MY FRIEND!!!
Excellent video as ever, it's nice to find somebody who emphasises the importance of good setting up and measurement.
I've never liked the casual way that too many people use verniers for marking steel: even with marking compound, there will be damage. What I find myself wondering is the best way to transfer a measurement from a vernier- or for that matter from any other kind of calipers- to Jennies for marking out: I can see how it could be done with a surface plate and height gauge but there must be a better way.
A wealth of information Adam......Thanks Jon
Great video, I have not used that type for years, but I need to get them out and use again.
hi my name is troy I have been watching all of your videos I think you're an awesome person you explain things well and show people who don't know how to do what you do do them an inkling of an idea of the amount of work you do too I think it's awesome keep up the good work
+Troy Wenhold Hey Troy, thanks for the comments! 👍🏻
