MACHINE SHOP TIPS #22 Micrometer Quiz Part 2 tubalcain

This is part 2 of a 2 part video on the micometer. Tubalcain shows the many different types & styles of micrometer calipers. This part has a 20 question QUIZ on reading the micrometer. The answers are at the end of the video.

[@Chadbordeleau]

I salute you, sir. Your obvious love of teaching really shines in this video. You are really doing a service to the world, passing along this information for others to carry on. What a great teacher you are.

[@John4566442]

Sir, I have been watching your videos over several days now and you have taught me more than my high school metal shop teacher did 20 years ago. I wish I had been a student of your's then, but I am thankful to have you now. You are inspiring and an excellent teacher. I thank you.

[@simpleman283]

I missed 5 & 9 ☹️. I am a carpenter but watching shop videos because I want to learn as a useful hobby. My Dad taught me how to hold the mic 40 years ago. One time he showed me how to use the inside mic on the bore of an engine cylinder. At first I thought that I would never get it but I did not give up and when I finally got that TDC drag, that was a very good feeling. When I get a lathe and need to use his old mics I'll know how to adjust them because of your videos, if ever the need as he has passed on now. Thanks Mr. Pete. So long for now.

I'm not a machinist by any means but I did learn plenty and I wanted to thank you for taking the time to explain it so thoroughly and giving lots of examples.

[@daveharriman2756]

Well I've been reading micrometers for over 50 years, and strangely enough I had to think carefully on some of these questions, mainly the internal and depth readings, a bit of a trial for this old man! very enjoyable, thank you.

They say you never forget a good teacher. In my middle age now, I have another name to add to my list - many thanks

[@mrpete222]

THANKS YOU VERY MUCH

[@pmfsv]

Can't help but be amazed at the lengths you go to provide knowledge to others. That 20 question quiz was a glistening red cherry atop a "perfect cake"!. Kudos (In the most literal sense of term)

[@lmr641]

I just recently started a new job on gear cutting at a machine shop, and the first thing management asked was if I knew how to read the micrometer. A very essential tool. Thank you, sir. You're a very good teacher. I have learned so much from your videos. Keep up the good work.

[@timmyj4392]

Thank you so much for your videos. I've inherited a 1931 South Bend lathe from my Dad, but it's in pieces, so I have much to learn. This micrometer video educated me, and was fun as well. Thanks again for everything

[@mrpete222]

[@melodoubt]

Brilliant !! . I just got a couple of mics today and thought to myself ''see if Mr Pete has any clues on how to read them properly'' Jackpot! couldn't have wished for a clearer tutorial. Scored 18/20 in the quiz first time through. Thank you

[@mrpete222]

Excellent!

I am from India, even though we use "Millimeters" and not inches, your video was very helpful for me. I could understand every bit, I wish we had shop teachers like you in our training center. Thank you Very much, Sir.

[@sthor3764]

You are a great teacher. I must get ALL of our mechanics at work to watch these two videos and take the included quiz. I am an aircraft inspector, your teachings here are going to instantly clear the fog. Thank you.

[@ShaiHulud1982]

I watch your videos and suddenly I'm 15 again and remember watching sword fights with files, getting sprayed with oil someone put in the keyholes of lathe chucks, and seeing someone pee in the kalamazoo saw coolant because he was too lazy to go to the bathroom. I have to say that I have learned more from you then I ever did in my high school. Thanks so much for your time and Knowledge!

[@BruceLHommedieu]

Helpful. I am getting ready to go back to work at a machine shop and I haven't done it in a while so this really helped me to brush-up on reading a mic again. Great pace, very clear and precise presentation. I really enjoyed being able to quiz before walking into this again. Thank you for posting.

[@breedist]

thank you!It is one your best videos you gave some people do not buying a micrometer and just practice just watching.It is a great practice,indeed.

[@pavski]

Very healthful and enjoyable video. Thank you. No experience in machining you made it clear and straight forward.

[@joleenmorganjohn]

That was fun! After 13 years in the trade I never been so excited to take a quiz on reading mics. I never paused the vid. except to check the answers, and got them all correct. Phew!! I'd be ticked at myself if I got one wrong. I cant get over how clear that camera is. I wish I could see my tools that clear in person. Another Great video!! Thanks

[@BradyQuinn10ND]

Thanks for all your videos Mr Pete! We really appreciate them! You have helped me as well as a lot of others, your a Great teacher. Thanks again!

[@SBBlacksmith]

I just want to say thank you for the videos. I have been a blacksmith for about the last three years and I'm starting to get more into the machining side of things. Your videos have been a great help. Keep up the great work. -Kyle

[@richardkicklighter1202]

I like your quiz. In the real world, a goof up could have expensive consequences. Unfortunately I did not do as well as I should have, and got a "D".(I'll have to stay after class and help clean the shop)! I went back and watched it again. The 2-3" ,and, the depth mic got me. Thank you very much. I have gleaned an immeasuable amount of information from you. Best

It is a 84 TLC 2136, Don't know why but I was looking for a small Atlas and found this, Paid $500.00 for it, it came with a lot of tooling. The PO was a machinist and this was his "toy" at home. I don't have a QCGB but have all the gears. No Automatic Apron either, sort of wish it did. It only has the 1/2 nut for feeding,no clutch. I'm still lucky to have found it I think. !!!!!!!

Another great video, many thanks. I got the inside micrometer ones wrong because I assumed you needed to add the 0.200" to the reading so I learned something there. Keep them coming!

[@Robtheregulardude]

mrpete, thank you, I should have watched this sooner, I had an evaluation yesterday for a machine shop program, I didn't do well, and was denied. I am disappointed and feel I didn't get a fair shake. One thing I had to do was set a micrometer at the random numbers the instructor gave, after a 30 second lesson. I had a hard time. I had never used a micrometer before, and didn't know how to read it, and I didn't completely understand after the hasty introduction. It makes more sense now. I did ok on your quiz, but still got nine questions wrong.

[@nnaatz1]

thanks for the vids, i am a home self tought machinist so to speak and learned a great deal from your videos. theses helped me produce much better results in my shop and projects. yes i did the quiz! one wrong!

[@rlsimpso]

Woo Hoo! 20 for 20. This was a great refresher. Thank you putting it together. I have to admit I usually use a Mitutoyo digital 1 inch micrometer that reads to 100th's and a caliper for everything else. I have a 1 to 6 inch set of analog mics with a vernier scale for measuring larger sizes more accurately then with a caliper.

[@mrpete222]

I bet he was a great man

[@bradsneed4521]

I would challenge your answer to question 10. You said the correct answer is 2.715. However, the 15 has not passed the read line, so I say 2.714+. If we had a Vernier micrometer on this measurement, it would most likely be between 2.7147 and 2.7149. Do you agree with me? If not, please explain it to me. Thanks!

[@not2fast4u2c]

I enjoyed learning this You are a Great Teacher !!!

[@scotmarq]

Very good I am an electro-mech tech. student, I will pass this on to my teacher.

[@havebenthere]

Great video! I missed no.11 so I went back and seen why. Had 3.374 instead of 3.376. It's easy to misread a mic. You don't want to have things going on or any kind of distraction while reading one. I always double and triple check my readings as; too snug or not can result in variable readings. This also helps minimize your chances of misreadings at the same time. You can't go wrong measuring twice!!!

[@BrokenPoetics]

Thank you for the video.

[@palmtx]

I got a 90% on this test. That is why never go on just your first reading. Measure TWICE and cut once. Three times if it's allergy season and your eyes are itchy like mine are right now. That is one of the best rules of this or any trade. Time spent measuring is a lot shorter than time spent starting over on a new part.

Great video and liked the quiz you did. But excuse my ignorance .., when the gauge changed to a 2 inch micrometer does that mean an inch is added automatically to the total sum?

[@kg6tgr]

Nice video. I like the test.

[@YST5700]

Good demo. It doesn't get much clearer than this. I tend to trust mechanical micrometers/calipers more than digital because they can't "lie" as long as the thread pitch is accurate. Capacitive sensors in digital models could be subject to moisture and other artifacts, so they seem (theoretically) prone to random errors. Maybe that's more speculation than fact.

[@BCLSundayFunday]

Hi Mr. Pete, your videos are such a great resource! I'm curious when you would choose to use micrometers over digital calipers. Are they both equally accurate?

[@NOBOX7]

can you tell me how tight i should go , i mean on some pieces i can get different readings but a micrometer has a tremendous mechanical advantage so its easy to smash into the work, any tips on torque ?

[@anita050971]

Thank you so so very much i have more to learn i was correct on the fraction part but forgot to reduce to lowest fraction i need to learn how to read a dial calipar, and still working on that i in fact was going to lowes or home depot to buy a calipar i need to finish the job appl and i should be good to go, thank you so much i love your video

[@mrpete222]

@cougarman07470 No-do not file it. What is the brand of the mike?

[@heliarche]

I scored an %85. Then I went back and saw what I did wrong and now I'm embarrassed. I missed #1 since I forgot how to add for a second, #13 because I didn't notice the thimble was just covering the line so I put .493 instead of .503, and #15 was the worst mistake. I put 1.050 instead of 1.750 because I was reading the lines on the barrel, the numbers on the thimble, but didn't add in the numbers on the barrel. Thanks for the lesson!

[@simpleman283]

I missed 5 & 9 ☹️.

[@TXKurt]

It's a 1 inch micrometer, so it starts at 0.000. Each division on the sleeve/barrel is 25 (thousandths) and there is one showing -> 25. You can read 15 on the thimble which means 15 additional thousandths. Add these up: 000 + 025 + 015 = 040 (thousandths).
