You overlooked the Vernier calipers. In many ways they are superior to dials or digitals. I always have a vernier caliper ready as a backup and reference. Both dials and digitals can be wrong at any point in the scale and you won't know, but not verniers.
Sorry Bill, but that is not correct. The digital callipers are more accuracy and precision. A mistrust of modern digital technology has given rise to this rumour. Cheers, Michael 🇦🇺
@@SpatialGuy77 You don't know what you're talking about. All calipers have the same accuracy. Only Vernier calipers never give a false reading. Digitals and dials both can give false readings.

wow, always very usefull!!thank you so much!!! I'd like to add just a detail. to push the callipers performance isn't a bad idea to zero them with a gauge block with a value very close to the entity you need to measure. to bring the zero close to the value of the misure is always a good idea and can avoid lot of methrological complications
U mean beside the fact that metric is the system that science uses internationally? And beside that imperial is defined based on metric standards? Basically we are already using the same system we only have different 'standard measures' As far as it goes for me measuring temperatures could look like this 295 K instead of roughly 22 °C/77 °F. Not even speaking of grams and newtons

Nah imperial is better. The only problem with it is the way they do subdivisions is unpolished. If they had just fully embraced the binary system we wouldn't have this thou nonsense
Remember... back in Ireland we got skilled programmer and machinist from India, with mamy years experience. Who came in to the shopfloor? A liar without skills, just a boy, didnt even know what is the pitch in thread, so he was drilling with tap... Doesnt matters What matters is this lovely mechanic slang Mark talks about. That boy repeatly was coming to me asking if i have four emum drill, six emum mill, twelve emum chamfer.. Took me a while to understand that he reads milimeters (mm) as Emum... 4.3 emum drill, drilling ten emum deep
When we train our aircraft mechanic apprentices, we use a standard manual vernier. They have to make measurements in inches, convert them to decimals and make them metric. Then they can control themselves by reading out the metric scale. They also have to do the same the other way around? Why do we teach them Flintstone-measuring? Because we can...
I noticed you didn't align the spindle zeroes of the digital mic's when you zeroed the electronics. Is it not necessary? I've been aligning the spindle zeroes of my digital 1" mic, using the ratchet knob, assuming I would get a better force, and avoid over, or under tightening. Thanks for these Tip vids. Well done, and good info, both as new info, and a review.
Excellent video, the biggest thing I learned is that the Metric system kicks Imperials ASS! Why is the US system so inconsistent with its measuring standard 5280 ft to a mile versus 1,000 meters to a kilometer 🙆
5,280. And 3 teaspoons to a tablespoon. 4 tablespoons in 1/4 cup. 2 cups in a pint. 2 pints in a quart. 4 quarts in a gallon. And this is why I too love the metric system. "If God had approved of the Metric System, He'd have given us ten fingers" :)
Great video, wow metric system is so much more convenient! Straight up round numbers, why do we still do it the same way as 100s or years ago when there is a simpler solution?
Decimal inch is just as convenient for those who are fraction impaired as mm. When it comes to reverse engineering a part, it is generally easier to reverse an inch based part because you'll be fairly safe to assume the larger scale dimensions are based on 1/16ths of an inch. In metric, you cannot assume this and have to wonder whether the dimensions are to the nearest mm or half a mm. Oddball measurements in metric are harder to resolve into the designer's original intention. This gets really bad when inch based drawings are converted to metric, giving 3 decimal place metric measurements implying false precision to a part that was not precision at all.
nice video, i think this "measures up" , but Witworth is another form of fractional inch that america uses, NOT to be confused with the English inch system. and IS different, ever wondered why that 3/8 " spanner doesn't fit an old cars bolts?? , This is why ( its a wit worth threaded fitting!!). but the BEST system is the FRENCH one ( the one the WHOLE WORLD uses) aka the ........ METRIC system (mm, meters, etc.), none of those crappy fractions you have to add or subtract in your head!!!
That's why you should never let a tape measure slap back into the housing. It elongates the slots and over time makes your tape measure distances wrong.
I'm so glad I don't use imperial. If you've grown up with it then it's probably fine but metric is so simple as you don't have to use your brain as much which is very important if your being rushed or stressed out.
thou caliper :D would be nice to have mike that reads that much decimals. Or better yet digimike. Some people read between the lines on a mike that only reads 0.01mm, so they read 0.005 out of it. I dont like that. Same as you cant read 0.5mm off a tape measure.
audio too soft. right click -> stats for nerds -> volume : -8.2dB. You'll want to amplify or normalize the audio in post processing so it is between 0 and -2 dB
Most of the world has converted to metric over the olde British Imperial due to its simplicity and sense.. but the olde imperial still has its place. I wonder though how many patriotic ‘Mericans stick with imperial foolishly thinking it’s their own forefathers invention?!
As an inspector, I have to be ready for both. I talk to operators that think in one unit or the other. But can the world please get together and decide on first or third angle projection?
Metric is crap for machinists. Great for mechanics wrenches. I do both and imperial is better for machining and metrology. .001" is perfect for most everything .0001" for fine work is just right. The resolution of the metric system is clumsy and impractical, forcing machinists to count by 5's or 2's or some shit in between. .1mm is too big .01mm is too small and .001mm is way too small. The use of commas is idiotic, I'm sure they did that just to be "different", very french.Not to mention that thread chasing dials are near impossible on metric lathes which are standard in imperial lathes because metric threads are not whole fractions of the master lead screw.
@@yosyp5905 15/64??? lol We machinists are not bloody carpenters with rulers man. NO ONE in machining uses that. But yes the whole metric comma instead of a decimal point is utterly stupid.
I have one more tip. Have a buddie check all your mesurements of your first part before you start running your parts. You will make mistakes.. and making 100 parts of scrapmetal isn't fun...
Metric is the best! I'd flip the switch to metric right now if I could. Makes so much more sense in many ways. Changing over measuring tools will always be a problem for us here in the US though, and I'm not sure when we will finally change. For now, we work in both Metric and Imperial. Doing automotive work, everything was in Metric, and on a day-to-day basis we did a lot less math, fewer conversions of fractions
.001 = one grand .01 = ten grand .0001 = also ten grand Figure out how to keep these three facts straight and you're half way to mastering the fixture business.

Awesome video. This video would have been great when I went through machinist school. So,e people had a hard time grasping these basic concepts. You explained them very well. Thanks!
The US is too stubborn to change to metric system not knowing it will save them a lot money, resources, time, headaches, etc the advantages are numerous.
G'day Mark, I'm a manual machinist but your videos are just awesome mate. So much applies to both worlds (CNC and mine) and I can't believe there is so much I didn't quite know, or, embarrassingly was just doing wrong - even after a lifetime of machining. You are an entertaining presenter (dad jokes included) and even watch you G-Code videos, very interesting! I could learn that! Being recently retired after an accident, I'll never use a machine like a HAAS CNC 🤤 but my thought are turning to a home CNC conversion. Anyways, wanted to say thanks so THANKS! Merry Christmas to you and yours mate. Cheers, Michael 🇦🇺 🎅🏼 (PS: I knew everything in this video 😉)
I too would like to see a thorough video on dial bore gauges from Hass. There are videos on TH-cam about setting up and using bore gauges. It's the way Mark compiles and presents the information, that makes these videos so useful.
Hey!!! The micrometre at 02:40 was inspected by Johnny B!!! Oh, Johnny B, how hard it is to see, just open your eyes and listen to me. (Old guy machinist teaching Johnny B to read a vernier scale)
In Australia, we don't use the centimeter, it is forbidden. We only use units with a factor of 1000 to prevent confusion, so only microns, millimeters, meters, and kilometers.
9:00 - Yea.. I'm from the US and grew up with the US inch imperial system, I strongly believe the inch system is only good to the point when you need precision measurements up to 1/4" or 1/8" inch... anything lower should be CM or MM. I know you're gunna hate me for saying this... but people who does precision machinists work using inch are bunch of great APEs. I know for a fact that some real pro experienced machinists in the US always have some metric measurement instruments because they do understand the level of stupidly of working down to the "thou" when "millimeter" and "microns" is much more logical and less error prone to work with. Theres absolute no reason to add a bunch of zeros before the inch decimal point and measure by the "thou", it's stupid. If you say it's more of cultural, flavour and history thing based on preference, I also think that logic is stupid since it's irrelevant for thinking and doing advance precision work the most logical way.
Always funny to watch the metric vs imperial wars here. However, the US (of course and Burma n Liberia) are dooming their kids with the use of imperial units. Do you have any idea how stupid it is to learn physics, chemistry with imperial units? Countless conversion numbers. Therefore lots of their kids will never really understand those equations, and cannot develop a systematic understanding. The only great thing about imperial units are their names, easy to pronounce, mouthy. About sending rockets to the Moon, you can use stone n potato as units to do so as long as you relate them to grams, like the US has done.
12:29 - "Corner radius" there is so much angles and corners to look at and not sure which corner is concern. Left by tool, I'm assuming it is the CNC mill's cutter tooling. Took me 3 days to finally comprehend what is being discussed here, zero info of details on the subject on the internet / youtube. I can actually see the little radius on the angle...
I would like to thank the community for my machining fitting all other parts around the world and the good lord himself for giving me these skills ,your welcome

Thank you for the most valuable information on measuring instruments.I really like all videos.
Great video. I might add the combo square and the old school spring calipers are great to have around too. Maybe in a CNC shop they're of less value.
Gage R&R is important. Use the correct metrology device based on the tolerance your working towards.

forcing machinists to count by 5's or 2's or some shit in
between. .1mm is too big .01mm is too small and .001mm is way too
small. The use of commas is idiotic, I'm sure they did that just
to be "different", very french.Not to mention that thread chasing
dials are near impossible on metric lathes which are standard in
imperial lathes because metric threads are not whole fractions of
the master lead screw.
Been going through all these basics and im really happy that most of the basic tip videos arent new knowledge, although i dodnt know the hole center trick with the caliper.
Like from Ukraine.
