- This video provides a short introduction to gauge blocks and how they are used in the machine shop, followed by a demonstration of how to select and wring blocks into a stack of the desired height

Gauge blocks are ground, go through several stages of machine lapping and are then hand lapped to size. I took a tour through a gauge block manufacturer once and the final sizing area was bench after bench of women with lapping plates, optical flats and electronic gauges sizing the blocks.

You explained this process very professional.....I worked in Q.A/Q:C for 47yrs. And I can tell you I'm missing this type of work.I'm RTD now
It's really a wonder that we can afford "economy" blocks, and use them to calibrate our OTHER cheap measuring gear! Reading some old books that mention the introduction of this, that the true original Johansson block sets came to America at something like $900! Might have been a few years' pay for the guy on the factory floor there. An aside about quality and "wringing"- I once got to try a set of ceramic gage blocks in a salesroom, and it was really amazing! They just went together so easily, the impression that they were magnetic was very strong, even though they were this white ceramic material. Those are a few thousand dollars I think, which is probably a bargain even so, and still much cheaper than the 1920 originals.
Tom - Great Video , well articulated . Two thumbs up .
Very interesting. I am familiar with Jo blocks but never owned a set. Knowing the process to get to a specific stack is a real time saver. Showing an easy one and a less obvious one was a great lesson.
Why don't they have stainless steel gauge blocks?
I was not going to watch because it just seemed to simple of a subject. What could I possibly learn? As usual Much to be learned even about the simplest things! I just got a set that had the screw in the center to hold them together. Never would have thought you could get them to stay together with out a screw!!!! Thanks for sharing your great knowledge.
Gauge blocks are a very useful tool, but they must be treated with respect. Glad you enjoyed the video.

VERY GOOD instruction.
Once again, Tom - I learned what I needed from your vid - THANKS! Just acquired a modest set of Do-All gauge blocks and turns out I was a bit off base on how to wring them! The part about the lab-grade blocks growing together overnight was new info... amazing!
Fantastic video very clear, simple, and useful instructions. Well done Tom
It's not only air pressure that holds the blocks together ... two (or more) gauges wrung together will stay firmly conjoined even if put in a vacuum chamber and all the air exhausted.
Thanks, I'm glad you enjoyed it.
Very informative and well presented! Thank you..
great video! You do a great job thanks for taking the time to make.
Thank you very much for your video. I am taking the class on Inspections Technics and the two examples you gave on stocking blocks technics finally enlighten me on the matter!
Great explanation in this vid! I'm taking machine/industrial technology math and this vid definitely helped me get through the chapter for gage blocks! Keep up the good work!
Great video. Very informative and thorough!
