Nah, I don't think these are at all related to the other scissors style. I think these likely have an entire internal assembly mechanism. There is enough space in the thickness around the adjuster on that side of the forged body.

Actually, in the entire post here, no one seems to have understood the real issue at play. I explained it rather poorly. The flatness issue is the shoulder under the head of the bolt in parallel with the under side of the but. There must be clearance for the nut thread, which will always allow the nut face to tilt out of parallel. Scissors generally seem to obfuscate this problem with the curvature of the blades.

I think there is some extra small trick in the mix. The location of final thread helix contact when/where the nut is tightened to seems important. This seems to set the initial shearing location along the length of the blade. If done incorrectly, the scissors may work well from some arbitrary point along the length, but not from the start of the shearing blade. Bending the blade does not change the behavior, and neither do washers or lock washers. However, a steel rivet does not have this issue even when it gets a little loose from wear. Any general purpose screw and nut has this issue. I have a large selection of hardware at home for use in 3d printing design, like I have a better selection of M2-M8 than any hardware store around.

I'm not sure how all the different designs are decoupling the thread clearance and helix issue, or if they are moving it to some indexed location. I was half hoping that someone would see the post and chime in about it being some common design topology because it is such an ubiquitous tool.

The professional hair stylist's scissors have the most wild variation. The tension is adjustable using the little tool spanner against the cross dimples. The wild part is that there are detents to how it tightens and does not feel at all linear. The detents are counted and each feels the same. The mechanism feels strange, like something one might expect in a pocket watch, not scissors.

It has to be the link from the root instance. It also needs to be the username@instance syntax

Like religious text logic but less ambiguity...Actually, I had a moment of curiosity about the word choice with fascinate here.

Etymology
Borrowed from Latin fascinātus, perfect passive participle of fascinō (“to enchant, bewitch, fascinate”) (see -ate (verb-forming suffix)), from fascinum (“a phallus-shaped amulet worn around the neck in Ancient Rome; witchcraft”) + -ō (verb-forming suffix), itself of obscure origin.

Verb

fascinate (third-person singular simple present fascinates, present participle fascinating, simple past and past participle fascinated)

  • To evoke an intense interest or attraction in someone.
    The flickering TV fascinated the cat.
  • To make someone hold motionless; to spellbind.
    We were fascinated by the potter's skill.
  • To be irresistibly charming or attractive to.
    Her gait fascinates all men.

Tensor.art is even worse garbage and a waste of time.

Working on a major attempt at training and civitai has garbage filtering and moderation. Like I am not making kiddie bullshit. I'm making family stuff I miss from growing up and places I can never go after disability as my primary motivation. The authoritarian bullshit is not something I will ever support. Surely we have an alternative? Is there a peer to peer? Maybe an onion site, or somewhere with even a sliver of ultra conservative liberal democracy? Cause this fascist and authoritarian stuff is ripe to disconnect the internet entirely.

Can we just normalize 'come lay down somewhere and relax?' That would be great. Thanks.

No chairs. No standing. Nothing weird. Just lay there and chill together. That is a social life I can participate in.

No way am I doing either.

 

An hour spent commuting is 1/16th of your daily life, and that hour is by far the biggest risk to your life every day. You should be getting triple pay to ameliorate the hazard risk it represents.

 

As in theme park and water park, opposed to national park and public park.

It seems like a bottleneck in language that I am struggling to find a way around. I believe the word park is poisoned in embedding models and would like to test that theory but I'm at a loss. I tried my usual thesaurus, looking at translations, and at etymologies but it seems like the word has no effective alternate so far. It is a rather interesting conundrum beyond the scope of my application – how would you differentiate and specify what a place like Disneyland is, without ambiguity, when "park" is not a useful word? And no land is not specific enough to describe the place.

I have a few ideas and stuff I have tried but I really want to know your ideas.

Etymology according to Wiktionary:
From Middle English park, from Old French parc (“livestock pen”), from Medieval Latin parcus, parricus, from Frankish *parrik (“enclosure, pen, fence”). Cognate with Dutch perk (“enclosure; flowerbed”), Old High German pfarrih, pferrih (“enclosure, pen”), Old English pearroc (“enclosure”) (whence modern English paddock), Old Norse parrak, parak (“enclosure, pen; distress, anxiety”), Icelandic parraka (“to keep pent in under restraint and coercion”). More at parrock, paddock. https://en.wiktionary.org/wiki/park

This is a 2012 Lazer Helium cycling helmet. They came with this silicone gel pad. I had one of these and loved it. Lazer does not make/sell these any more after they were bought out by Shimano-America.

These pads were odd in how they were packaged originally and had no form of branding, hinting that they may have been sourced from some other industry or application. Search engines are garbage when I try to find the abstract application keyword for wherever these originated from due to advertising disinformation obliterating anything remotely useful. I imagine these may come from something like surgeons to prevent sweat contamination or for very hot environments like mines or foundry work. Does anyone know of applications where they have seen a pad like this sold or used?

 
 

I want to try making a bubble lens cover for a display enclosure. I'm thinking about a simple sandwich of sheet metal flashing with a center window to clamp a sheet of 2mm acrylic. Then place a nichrome wire heating element under the exposed acrylic. The heat will rise and gravity will deform the window to create the bubble.

I could probably get by with a sketchy setup that wraps the nichrome wire around nails in a wooden frame for a one off. Alternatively, I could probably use mica sheets, like a typical domestic toaster, to build a frame that the wire wraps around.

What I'm curious about is if labs have some better goto setup to create custom heating elements. Is there some kind of erector or Lego like set of cheap hardware people use for creating custom heating apparatuses? I'm thinking like a set of ceramic standoffs and a configurable base plate or other basic hardware. Like if you wanted to automate a medium size production run of something and needed a few different size heating elements, how would you build them?

 

(Electrical Discharge Machining)
In terms of current, voltage, frequency, rise time, etc. What makes this one special for switching topologies?
