Spring-Joint Calipers inside/outside

[@machiningmoments]

I agree it is "touch" gives me great repect for the old timers who used this tool lots. Thanks for leaving a reply.

I've spent time and will continue to spend time with millwrights/machinists of the Era gone by. Batteries fail when you least expect or devices fail ie human error. Point being I too have respect for the calibrated fingers that take decades to acquire. Thank you for an informative video.

Thank you very much for including the firm joint nomenclature, and thanks for posting all of your videos.

[@machiningmoments]

Glad to help. Thank you for watching and posting!

Thanks for the video. I have had certain situations where the inside calipers are the only measuring that will clear obstructions to get an accurate measurement. This is definately in my opinions the hardest measuring instrument to learn because its all dependant upon "feel". When used correctly with the proper "feel" I would argue one can obtain very accurate measurements within 0.0005" or less when compared to other measuring devices such as inside micrometers.

thanks, im studying for my asvab. it is very much easier to memorize things when i know how it works.

[@machiningmoments]

Good luck on your test!

[@hvolboll]

Great video it's all by touch and feel thanks.

[@sloppydoggy9257]

Recently got myself a middle out spring caliper its great.

[@machiningmoments]

They are great for tight spots.

[@chernobyl1987]

Useful for my ASVAB test!

+Origami Killer Same reason i'm here. How did you do on your test?

[@yolandamunoz6862]

lol here for the ASVAB as well. Thanks for this!

[@machiningmoments]

Thanks for watching, good luck with your test.

what's the margin of error for calipers like these? it seems like there's a lot of ways to go wrong on technique, but i'm curious about how close i could get, barring major errors.

[@machiningmoments]

The margin of error honestly is the operator. I know people that can accurately use these calipers to 0.001" The trick is practice and patience. These inside calipers are great for checking the size of a grooves diameter.

[@kozemchuk]

machiningmoments that's impressive. thanks for the info!

What occupation would these be used? My grandfather had these in his possession. He worked with wood.... A general contractor in the 1900s

[@machiningmoments]

I am a machinist and they are used in my trade. They aren't used a lot anymore...a tool from another era. Thanks for watching.

[@AS-ug2vq]

@@machiningmoments which tool is now used in their place now?

[@GameLab_Studio]

I like it.

Thank you for watching.

[@CaptainCretaceous91]

I've seen a sculptor use the outside ones.

[@JasonMontell2501]

My grandfather used these on his lathe when turning wood for table legs.

[@machiningmoments]

:) cool!

[@machiningmoments]

The old timers make the use of this tool look easy!

[@machiningmoments]

I believe they are Starrett.

[@briancarpenter6413]

couldn't you just lay the ruler on top of the pipe?

[@machiningmoments]

Absolutely

[@ironsmith9769]

only if you are measuring a surface which you can lay a ruler against and that surface is perpendicular to the objective measurement desired. for example imagine you need the inside diameter but the face of the cut is at a 45 degree angle. if you lay the ruler on the surface you will get a measurement up to twice as long as the actual circumference. to take that measurement you will need a square and you will need to take many measurements to get the shortest. also, if you are measuring something that has different dimensions at different depths such as is often the case with turned parts. they make digital calipers with extra deep jaws to take extra deep measurements but even then they cannot measure cavities where these can. i got some of these so that i could measure accurately the maximum width of a semi regular doughnut shape. to take the measurement with a simple ruler would have been impossible, i would have needed three squares and 4 extra hands, or have made some kind of jig. plus a set of these at 12 inches is about 1/3 the cost or less than digital calipers that could measure the same distance and still would not have solved my problem. i get issues anywhere from 6 to 20 times a year where calipers like these are better suited for the work.

[@Moko_Bomoi]

anyone else watching for the ASVAB ?

[@machiningmoments]

ASVAB?

[@Moko_Bomoi]

Yeah bro , your video helped me a ton on the auto and shop sub tests of the ASVAB (military entrance exam)

[@machiningmoments]

Glad to hear test went well!
