I knew AvE's video would show up :D
Re: Wringing
#5This reminds me of a phenomenon called cold welding, where if the surfaces are flat and clean enough, the blocks of metal will fuse. Just touching two sufficienly thin gold wires will weld them.

#6Who knew intermolecular forces could be so strong? This blew my mind.

#7This is such a beautiful HN post :) thanks!!
Re: Wringing
#8I wonder how stable is such a "wring joint" over time and over mechanical stresses like temperature change and vibrations. Could you use this feature to e.g. attach stuff as a product assembly technique, as a temporary/non-destructively modifiable alternative to gluing or welding?

#9If you're interested in how gauge blocks fit into the history of precision engineering, a new book called "The Perfectionists: How Precision Engineers Created the Modern World" puts them into context, and presents a very interesting perspective on the events and developments that brought us into modernity. These blocks feature strongly into the industrial revolution. I strongly recommend the book!
