Gauge blocks (also known as gage blocks, Johansson gauges, slip gauges, or Jo blocks) are a system for producing precision lengths. The individual gauge block is a metal or ceramic block that has been precision ground and lapped to a specific thickness. Gauge blocks come in sets of blocks with a range of standard lengths. In use, the blocks are stacked to make up a desired length.
An important feature of gauge blocks is that they can be joined together with very little dimensional uncertainty. The blocks are joined by a sliding process called wringing, which causes their ultra-flat surfaces to cling together. A small number of gauge blocks can be used to create accurate lengths within a wide range. By using 3 blocks from a set of 30 blocks, one may create any of the 1000 lengths from 3.000 to 3.999mm in 0.001mm steps (or .3000 to .3999 inches in 0.0001inch steps). Gauge blocks were invented in 1896 by Swedish machinist Carl Edvard Johansson. They are used as a reference for the calibration of measuring equipment used in machine shops, such as micrometers, sine bars, calipers, and dial indicators (when used in an inspection role). Gauge blocks are the main means of length standardization used by industry.
Invented in Sweden in 1896, these this have been blowing minds ever since. I experiment with them to see how they work and test out if the explanations make sense. Accurate to within a blond one ✪►https://www.etsy.com/ca/listing/464202928/one-rule-to-ruler-them-all-cheeky-jokes◄✪

Gage Block Introduction - How To Use and Calibrate Gauge Blocks
In this episode of the Metrology Training Lab series by Mitutoyo, we learn how to calibrate gage blocks, stacking or wringing gauge blocks and a brief history. These simple little blocks are something special. Each one with their flat and parallel surfaces and with an accuracy of just a few millionths of an inch. We’ve used gage blocks in previous metrology lab calibration episodes, but in this episode we get to understand them better and appreciate their role as a premier measurement standard.
Gage block faces are very flat and very smooth. The reason for this is that allows the gage blocks to wring together. Without using any adhesive, gage blocks can be brought together and the flat smooth surfaces will adhere to each other without causing any damage. And they can be broken apart and r...

Comparing Gauge blocks sets, Cheap vs expensive Jo-blocks
I will compare 2 sets of 81 pieces gauge block ( Jo-Blocks ), one is a Webber brand distributed by Starrett to another one distributed by Fowler, we'll discover that for the use in a small shop or for home use they will both do the work.
Companies like Starrett, Mitutoyo, will sell some of the highest quality sets to supply laboratory grade blocks for the highest precision.
Companies like Shars, accusize, and a few more companies are selling affordable sets.
Since I was unable to tell a real difference, even if in reality the difference does exist, it's beyond the ability of a small shop to measure those tiny variances.
In conclusion, for use in a home shop or a small shop you can get cheaper set and get the job done... If you do research, avionics, military, etc that requires certi...

And they can be broken apart and reused over and over. And when done properly, the gap between wrung gage blocks is somewhere around one millionth of an inch. And any flat smooth surfaces will wring together. Steel to steel, ceramic to ceramic, steel to ceramic, and even gage block to optical flats.
