When two very flat surfaces are brought into such close contact with each other, this allows an interchange of electrons between the atoms of the separate blocks, which creates an attractive molecular force. This force will remain even in a vacuum or if no oil or water is present on the blocks. The last two sources are thought to be the most significant. Preparation of Gage Blocks Prior to Wringing Make sure that the blocks to be wrung are free from nicks and burrs.
It is important that all nicks and burrs be removed BEFORE attempting to wring blocks together because a burr on one block may damage the surface of the other block. Blocks may be checked for burrs with a gage block stone before wringing. A gage block stone with serrated grooves is recommended because it gives a better "feel" for nicks and burrs that catch the edges of the serrations. Badly nicked surfaces will click as a nick passes along the serrations.
Wringing Gage Blocks 1. Make sure that blocks are clean. Wipe the surfaces of the blocks to be wrung gently across the oiled Wring Pad. Likes: 7 Post 2 Post 2 Post 2 Post 1.

If he does an update to this video, or shows if they do, infact, cold weld after a long period of time, I'll post it in this thread.
Although not lapped, I couldn't see the needle move on a tenths indicator while measuring them. I wonder if a vacuum changes that and provides the proper conditions to weld like gold nanowires for microscopic electronics work. And here is a short clip of gold nanowires "cold welding" Sent from my XT using Tapatalk.
SteveBausch , Ray Behner liked this post. Perhaps this cold-welding is a prerequisite for one of those "something for nothing" processes? When thoroughly cleaned, they would rub together, and at the bonding spots the transparency would go up looks darker because of missing internal reflections and just around the bonding spot there are rainbows visible diffraction patterns.
Thank you! You brought a child hood memory back for me! Language warning would be nice.. He drops the F bomb a half dozen times and has it written on his testing block. Not sure why he felt that was necessary. Not really. Like any condiment they have to be used sparingly. A well-placed invective can be both appropriate and entertaining, however overuse is both lazy and diminishes its impact.
You must be new here. Welcome to the internet. Is it like a magic word, that invokes an evil force? The logic behind a taboo on some words completely eludes me. Seems like one of those thousands of things people just do because everyone else does, and everyone else does it because everyone else else does.
Stuff like that pisses me off. The human race is illogical and fetishistic enough. A bit of logical consistency would be nice. The tone and method of conveyance can make a difference and how people respond to a word can make a difference but fundamentally, why are certain combinations of letters perceived as obscene while others which explain the exact same thing are seen to be more socially accepted?
Although, it can all depend on the context of the situation as language between friends could be saltier than language in public but this too depends on other factors. Education, the time of day, specific setting, etc. Amusingly, these and other noteworthy elements of language and culture have been studied to a degree.
Researchers at Marist College in New York say a big vocabulary of curse words is a sign of higher rhetorical skill, and those that can name the most swear words in one minute tend to have a greater overall vocabulary.

Middle-class people swear less, and like to think their station in life is down to their superior intelligence. Children need protecting from certain combinations of consonants and vowels, but only some, not all.
I would feel very embarrassed to watch this with family around, young or old. Geeks have never given a shit about that. His videos, while interesting and amusing, are becoming harder to understand due to his choice of words and more crude. The videos are becoming better made, contain better researched and more interesting subjects so hopefully a balance will be found between the language not just the swearing and the content.
I tend to agree. Even if you are not comfortable with crude language, it adds nothing to this sort of presentation. The project videos are rarer now, since the Patreon success…. I doubt it, more like his alter ego the uncle that much more interesting than your dad, talks funny and has dangerous toys, turned up to eleven.
I guess thick skin is a requirement given his sign off. Anyone that has spent any time in a machine shop knows that the language used therein is often colorful — but then again those that have spent any time in a machine shop know how to wring a pair of gage blocks. One would assume then his target audience are those outside the field and consequently he should be presenting to this larger audience.
