How to read and use a Micrometer...the right way | [FREE LESSON]

When building performance engines the micrometer is just 1 of the specialist tools you'll need to learn how to use correctly and it is a tool that some novices and professionals alike often struggle with.
Today we're going to use a vernier micrometer but the knowledge will also be applicable to your standard micrometer as well.

This guy is the definition of clear and concise presentations! Brilliant

[@Vgk36]

I'm in aircraft maintenance school and this block has all these tools. Great video!!! Thanks

[@ashantighania225]

Thank you! Also, my boss thanks you so, he won’t have to keep explaining this technique to me!

[@MrCornholios]

I was 16 when i learn how to read this tool and others in my 4 year mechanic apprenticeship.
Was a bit confusing at first time :)

[@stephencregorykelley9850]

Hey thanks for the refresher!!!

[@hpa101]

Our pleasure! Glad you enjoyed it =) - Taz.

[@jacobpereira7045]

Thank you this was very useful 🤙🏼

[@vonstarr6738]

THANK YOU!! You’re a Wizard

[@ashc5728]

great video guys, very clear instruction

[@hpa101]

Glad to hear you enjoyed it Ash! We'll have another one coming out on a different tool in a few weeks for you =) - Taz.

[@AndrewG2.0]

Excellent video! Thank you. I don't use micrometers very often and always forget how to read them.

[@BedsitBob]

I thought it was like riding a bike?

[@boostismagic]

Love your channel brother!

[@hpa101]

Glad you're enjoying it! - Taz.

I use old instruments of the Soviet Union. Chinese ones are sometimes very inaccurate. Perhaps now they have improved in quality.When measuring, it is probably advisable not to warm the micrometer bracket with your hands, since the values change 0.001mm

[@Limeayy]

Thanks great way to remember. You are on point with what your talking about than my instructors. They'll just have you give it a go or a demonstration with the ticks on the micrometer and you'll figure it out on your own. It's like if you see a pattern you'll figure it out. Btw note. you spells micrometer wrong for the title. lol

[@hpa101]

Thanks Lime, ahh you are right, fixed :) Thanks. - Ben

[@adamm2716]

lol andre that thumbnail looks like your pointing with a joint... still love ya man

[@hpa101]

Honest it's a pen! 🍁don't smoke and measure. - Ben

[@gaveonduffus52]

What if the sleeve stopped at the 3? Would the second written measurement be 0.000?

[@BedsitBob]

2:25 I think you mean the resolution?

[@tangles01]

I always have to write it down to get the reading... If I don't I get lost lol. Once I have a baseline though if measuring a crank for example I then only write down the last didget in most cases.

[@ivanrybkin9384]

sorry,
there are some clear errors in the way you use it, especially holding it, it meant to be thermally equilibrated both tool and measured piece, as holding it tight with your hand heats up the outside part of the micrometer, causing it to stretch and read incorrectly. also the reason for black pieces pop plastic on its sides are not just to stamp the brand/make, but actually insulated holding g point so you transmit as little heat as possible to the metal body.

[@Perumet]

Does anyone know what brand these are? Just bought an expensive set of Mac Tools micrometers and they're literally exactly the same... just says "Mac" on the black label instead of the range -_-

[@FightingSportsMedia]

lol his set were chinese, probably about $150. Sorry man.

[@Perumet]

@@FightingSportsMedia all good, I got them used for $100 so still a win

[@jonathanrogers9961]

A bit long winded. But good instructions

[@hpa101]

We do our best to be succinct but it is easier with some topics than others. Cheers for the support 😎 - Taz.

[@OskarasNauseda]

i can read micrometers better then calipers

[@lfn3311]

i know this is old thread, but i gotta let all know that when it comes to cheap/or any chinese made mics, you get what you pay for... i started with china-made mics in the beginning.... they seemed "off" to me. i didnt have confidence ib the china-mic inaccuracy/repeatability. i finally dished out for Mituyoyo mic's. all china mic's went to the dump after that. Ridiculously inaccurate and repeatable every time!

[@hpa101]

We've had both terrible and awesome tools out of China. If you are going to buy them, you just need to check and be sure what you have is going to do the job you have it for. You should do the same no matter how much you spend on tools or where they are from to be fair. 'Trust but verify' is a quote we think has a lot of value in this respect and many others - Taz.

[@dekoomers]

Precision measurement and imperial units shouldn't be a thing. Should be metric only.

[@petersonyra5827]

Bro

[@hpa101]

Cuz?

[@EppingForest304]

Inches? Is Australia not metric...

[@hpa101]

We are from New Zealand 🐑. But yes we use the metric system here too. When you are building engines you will want to know how to use both metric and imperial. - Ben

[@tangles01]

Having recently bought a set for my build, I can tell you finding a set in metric is bloody hard. I could find them but at the very bottom end of the quality range with 5 micron accuracy... I ended up up biting the bulled for a mid range set 0.0001". At the far end of the cost range were digital ones which measured both.

According to Curtis, at Cutting Edge Engineering, they use bananas. 😁
