Those in Metric land will know the Vernier Scale as the Nonius Scale. It's really simple and absolutely brillant: Basically when you have two sliding scales, one of them is usually divided in multiples of ten. By adding another scale that divides the same length into nine units, you increase your accuracy 10:1. By the way, I learned to work with a caliper that had a Nonius scale too. None of that fancy clockwork stuff! Anyway I bet they don't teach this kind of thing in high school anymore like they did in my day...

My cheap $10 HF caliper took me about a year to replace the battery - and even included one replacement battery. I will still be picking up a Mitutoyo one, but while I'm in the "bleeding out all of my money like a stuck pig" phase of tool-acquisition early on in getting into machining, anywhere I'm able to make due with a tool costing pennies on the dollar, if even only for a little bit, I'm all for it

I saw this "trick" somewhere in another machinist youtube video (can't remember which one, I think I've seen it several times now). Unfortunately, my vernier calipers aren't designed to do this, so it is not universal - at least it WASN'T when I got my calipers - they probably are 40 years old, and I think they design wasn't the latest at the time I got them. Still working, so not replacing them yet... ;)

Yes, the video is 3 years old and still GREAT. But, ya know, a lot of us old geezers who decided to squander our retirement vacation savings on machine tools, in addition to being self-indulgent, are half blind. So those BIG digital LCD numbers really help. Now, I have a harbor freight, and mid-range asian, and high end set of digitals and you are exactly right, but I also have gauge blocks, so I do check them. Have to be careful. HF is "accurate to a thou or two, and fairly repeatable. The mid price ($50 to 100) and the high end, ($250 and up) read within a tenth of each other. The temp variations in my shop could cause worse than that in any result I'd ever get. So...the ability to see the numbers, and the accuracy of the mid price units is something us geezers actually need.

I worked as an electrician in the construction industry for 35yrs and now I am working in machining. In construction + or - a 16th of an inch was accurate. It took some getting used to to handle .001 accuracy as well as understanding the need for such extreme accuracy but I'm loving it. I can now make things I had to buy before. Combining my electrical knowledge with machining ability has enabled me to make some really cool stuff.

Holy Cats! I bought a micrometer eons ago at Amble’s Surplus, not knowing at all how it’s used. Had no instructions. Decades before KZfaq. TIL that the extra lines are for 10,000ths!!

@kelvin0mql 4 жыл бұрын

Did a little more inspecting & I think I've found 3 reasons my micrometer was so cheap. 1. Genuine Chinesium (if I remember right, the original wood box it came in was stamped "Made in China" - lost that box years ago). 2. It has finish-blemishes on the big C-part which look like it perhaps had a brand/logo on it, which was removed perhaps because it was a factory second. 3. The ten-thousanths lines only go up to 5. So to read .0006 to .0009, you have to use the shorter half-a-hundredth marks on the barrel and do even more math. Fugly, but functional. What a fun day this has been so far.

Great explanation! I would like to add that the best way to hold a micrometer is either thump and forefinger on the black pads on the lowest point of the arc ..or on the fixed anvil side, that way you transmit as little of your body temprature to the micrometer. Gretings from the Netherlands.

I remember going to homestead air force base, near Miami, for a field trip in my high school physics class. We were supposed to get to see an F-16 but they weren't available, so we got a presentation by some of the USAF machinists instead. They had a good presentation on precision measuring and metrology. I just wasn't receptive to it back then. It was so incredibly boring. Fast forward about 30 years, and here I am, engrossed in a metrology video... I'm not a machinist, but having a lathe and a mill in my work shop is a decadent dream of mine, so some day.... I guess "better late than never" is an apt sentiment now. Cheers.

I love showing a lyman caliper (sold for ammunition reloaders) in this use. I've found several things that if bought from a different specialty than what you'd think - you save a ton of money and they're as good (usually the same, just different branding). FWIW, I lose the battery covers on my digital calipers and loosen the battery when they're not going to be in use for awhile, then push the battery back in when needed. Cheesy but it works (you could hot glue a small screw ,bit of tape, or a toothpick to the battery to make that easier). The normal tension in the springs of the battery holder itself keeps the battery in and connected no problem normally - The reason they go dead is they turn themselves back on, like ghosts in the middle of the night, and you can catch them at it. Static? Dunno, at least some brands are less likely to do that if you tighten the screw that keeps them from moving.

Going back to Shop-101 I was taught when checking calibration on you Micrometers in this case for example with a 1 Inch Micrometer but it really doesn’t matter if it is a 1”-2,” 2”-3,” or large micrometer. Any-who step number 1 is first with a lint free rag wipe the face of the anvil and spindle lightly and then wipe the face of the anvil and spindle with clean dry finger tip afterwards close the micrometer until the anvil and spindle touch as if you were taking a measurement. After insuring that your micrometer reads 0.000 or if did not that you have made appropriate calibration corrections you next then carefully open your micrometer to just pass 1.000” at which point you insert the 1.000 standard bar that you have cleaned the faces on just as you did cleaning the face of your micrometer’s anvil and spindle and tighten down on the standard bar as you would taking any other measurement and confirm that the reading you get on your micrometer is indeed 1.000” if it is any other measurement than 1.000” repeat the 0.000 calibration procedure and the 1.000” calibration procedure if you still get a reading error there is a chance that the frame of your micrometer is stretched or with the face of your anvil or spindle is worn. However there are other possibility’s is that need to be checked before condemning you micrometer or buying expensive parts if available to bring your micrometer back into specification. One of the simplest is to check if the spindle assembly of your micrometer is removable from the frame of the micrometer it may just be out of adjustment additionally it may have been over-torqued into the frame and some micrometers use shims to adjust frame to spindle spacing, lastly if the micrometer has not been treated as kindly as it should the mechanism possible could be filled with crud and corruption, if this is the case a good cleaning may possibly remedy the situation. Note keep Brake-Kleen and Gum-Cutter away from your micrometer. Lastly when storing your micrometer’s and calipers do not screw the micrometer shut or stick a standard in between the anvil and spindle faces overtime it is going to attract corrosion or rust and both of those are bad for precision measuring devices and tools in general. Hopefully you may find some of this useful if not that ok as well either way have a nice day and a better tomorrow.

Consider good used Swiss tools which are the best made machinist tools, period. The smooth feel of an Etalon mic compared to Mitutoyo, Starrett, etc. speaks volumes!

That looked very much like a metric coathanger... are you in danger of converting ? 😁 Don't forget fingers.. very precise things and can measure in both metric and imperial, handy when the old eyeballs start to fail ⚙️😺

I don't have any of those fancy calipers with the dial or digital mine are just the old calipers but they work

One thing of note (not sure if it has been mentioned in the comments yet) is that each manufacturer has its own recommendations on the number of clicks you should do on the micrometer. I think (but I'm not certain as I am on the wrong side of the world right now) that Mitutoyo recommends 3 clicks.

Hi Quinn, another great video! I always learn something new from your videos - this time flange measurement with dial calipers. Since this is a lathe skills video I have a lathe question. Do you ever wish you would have spent a few more $$ for the PM 1030 instead of the 1022? Or would it just waste valuable shop space? Upgrading my mini lathe within the next year.....

For me it was down to space. I really don’t have space for the larger machine. This one just barely fit! 😁

Hi, the caliper batteries. Cheapo's just have a relative scale, they have to keep the power on in order to retain the zero, switching them off just turns the display off. A bit daft as I think everyone rests the zero every time they turn the display back on atvany rate. The quality calipers have an absolute scale and they know where the zero is so can be fully turned off when not in use. Discharged batteries areca thundering nuisance and I think Quinn is absolutely (!) right to say avoid cheap measuring tools. BobUK.

The thing to remember about the cheap digital calipers is that the 'off' button only switches off the display. The rest of the electronics are still running and depleting the battery. Long ago I started to remove the battery after every use and storing it in the box (never throw the box away as it protects the unit!). Recently I forgot to remove the battery and it went flat screwing up the caliper even with a fresh battery installed. With nothing to lose, I removed the new battery and left the caliper to think about things for a few hours. With the new battery installed it sprang to life! If only that had been the case with the most expensive multimeter I ever bought. It never worked again after letting the battery go flat. Tens of pounds down the drain when £10 was *money!* (1970's). Regarding being perpendicular to the piece being measured: I've often thought that a 'left handed' caliper would be mores useful when working on pieces still in the lathe chuck. Mini lathes tend to have a back guard that gets in the way of a standard caliper. I wish I knew what happened to it, but I used to have a zero to 4" micrometer! It still worked the same (ish), but had interchangeable 'fixed' anvils of zero, 1", 2" and 3" so that the 'micro' part of the range was always 1". It was probably lost during one of our moves. I know I lost a whole circular saw petrol engine during one of them! Ps. Thanks for the tutorial.

There is one serious issue with calipers like you show: bits of metal get into the gear mechanism and cause the caliper to jam. It is the main reason for me going over to digital. The current cheap HF caliper battery seems to be lasting just fine (it is at least a year old and I don't have to take it out) and it has auto turn-on. After trying the Shars caliper at the metrology test that Kilroy was putting on, I may step up to one of those. Nice to meet you at the Good of the Land Festival.

Yes, very true. Dial calipers need to be taken apart and cleaned from time to time. That is a disadvantage of them.

How feasible would be to have a small bubble level built onto a caliper? At least in the horizontal dimension, it would be relatively easy to see if you were square with your part? In theory, there could be a second bubble level for the vertical dimension. Or, would that be too cumbersome? As others have said, this, like all your other videos, is very informative.

Regarding digital calipers battery drain. I flip battery in mine when not in use. Lasts for years now. Of course, you should inspect if you can do this without potentially destroying caliper electronics.
