great explanation and great example why Imperial needs to be abolished its a joke lmao, guy using metric measured all his bearings went home had a diner and is having a beer, while imperial guy still stuck on adjusting fractions to common denominator LOL

When I was a mechanic 50 years ago. I bought. A very nears 😊caliper but didn’t have a clue. So I went to the machine shop down the street and asked the old guy how to read it. Thankfully he was very patient and he first taught me fraction math and finally how to read it. I was very happy when the dial calipers came out.

I have got so used to metric after 50 yrs that I was struggling to remember how to add the 128-ths for an order. So many lazy ones just use digital inches (why mix systems?). This was both helpful and easy to follow, thanks.

Yes, it is. The math of decimal inches from 0.1-0.01" is on my dial caliper video. On my micrometer video the range is 0.1-0.0001". Manufacturers tend to make sliding instruments only accurate to 0.1 units. The dial caliper has gears inside for better accuracy, and micrometers have fine-pitched screw thread mechanisms for even better accuracy. Enjoy discovery.

Thanks for the video, a nice refresher for my old brain, question, you said @16:25 "they're not perfectly aligned" If we was turning down a shaft on a lathe for that bearing to run on what would we use to get the exact measurement?
@apprenticemath2 жыл бұрын
Micrometers lessen this misalignment problem by 10x, but that's about the end of hand-held solutions. Light (laser or visible) in some hi-tech bench devices or computerized robot arms, ... some fancy stuff for ultimate exactness. Calipers do ok for some manufacturing.
@darrenpickens71474 жыл бұрын

jst try the p+(q x least count) where; p= main scale reading just before the zero mark of the vernier scale q= nth vernier division that coincides with the main scale division Least count = 1/128 Therefore; 3 2/16+(3x1/128) = 3.148 or 3 19/128 This is just another way solving for the actual reading and for me I find it more easy because I just need to know the working formula.
@jonarbuckle15607 жыл бұрын
Holy cow. I got some unmarked calipers from a local hardware store. "import" ect Would I be correct in assuming if the number of hash marks/hair lines per inch on each scale is the same as these in the presentation, that I am dealing with 1/128 calipers? (This math is a mystery to me now) Intution says "yes" If so, these pieces of crap are acurate to .0005" with "rounding down" That is amazing!
@apprenticemath7 жыл бұрын
If marked the same way, then 1/128" it is, which = 0.0078", or 0.005" rounded down or 0.01" rounded up. Concept was invented in 1631 by French mathematician Pierre Vernier.

@andybilakshow260 Жыл бұрын
Correct me if I'm wrong. I know this vid is really old, but perhaps someone here can confirm my theory. This is pertaining to the "ID" of the bearing. being a hair over the 1/6th mark and behind the nearest 1/128th, Wouldn't it be more accurate to say the answer is 1-1/266th? So essentially you're dividing the verneir scale in half. Edit: It looks like the "8" on the sliding scale *is* lined up. Therefore the measurement would be 1-23/128"?
@apprenticemath Жыл бұрын
Readings could be rounded to nearest 1/128 or 1/256 but ultimately finer measurements needed a different approach to measuring length - micrometers.
@andybilakshow260 Жыл бұрын
@@apprenticemath Thanks for that. Would you happen to know an average standard tolerances for press fit items such as pulleys and or bearings? The best I could come up with was 1/1000th" difference between inner / outer. Seems kinda loose to me.
@estardoelenot.20704 жыл бұрын
Shouldn't we used LCD? 2/16 right? If we uses LCD it will be 16/128. (LCD. 128÷16=8) So 2(8)/128 Or 16/128. Your answer is correct but some of my friends were unable to understand if how did you derive in that answer. So for those who haven't understand it too we uses LCD to derive for that answer.

Digital calipers are great. They are. But I still use my Brown and Sharpe 570's. (both 13" and 25") Both are easily 60 plus years old and the quality of them are just incredible. (the wooden boxes alone are gorgeous!) Most modern cheap Harbor Freight calipers are....good enough....I guess. Depending on what you what from them. But if you go with digital, go with Mitutoyo not Tool Shop. Actually, spend the money and buy much older Brown and Sharpe and Starrett. You'll never regret it. Learn to read the old manual tools. Not the modern Chinese crap.
@joshuagibson25204 ай бұрын
Guess I got a mismarked scale on my caliper. Not only do the 0 and 8 line up, but so do the 123456 and 7. There is no offset on them. Nor on the metric side either. Same thing. They all lineup with no offset. Lol. Its okay. I just need to measure drill sizes the the nearest 32. It will get me close enough. They are $1.99 plastic calipers anyway. They are well made and marked honestly. Just there is no offset on the vernier itself. Its kinda funny the more I think about it.
