Non Compos Mentis posted:ahh so its kinda like solder Solder is a different game - its a different, lower melting point material that fills and bonds between your two bits of metal, there is no combining or homogenizing of the liquid. Weld filler rods are the same as the metal you're welding, you physically melt the base metal that you'ure trying to combine then add the filler to that weld pool. When it cools its physically combined the metal from both items together with the filler.

Ha! I've actually got something to contribute to the OSHA thread... My first job out of college was at Smith International, SmithBits division. We made those drill bits, though probably not that exact one. That's a Tri-cone bit (called that for obvious reasons)... the other ones we made were PDC bits which had no moving parts and had little columns of Poly Crystalline Diamond as the 'teeth' and a big hole in the middle. The drilling mud flows through and brings the excavated dirt back up and in the case of tri-cones, also does a lot of fluid dynamics stuff with the cones. I'm a software developer, and one of the cooler things I did there was help an engineer optimize a simulation for how the teeth hit the ground when a tricone bit rotated. You can see it in that movie that the teeth, which are orders of magnitude harder than anything else on the drill bit, should be the first to hit any piece of ground. But if the teeth aren't spaced correctly/optimally, you can get teeth hitting the same spot of ground digging a smaller hole which causes one of the cones to actually hit the dirt first. Engineer guy had made a simulation in Excel of where each tooth would hit dirt given a number of rotations of the bit/drill string. Of course it ran like dog poo poo. So I helped optimize it and secure it (proprietary technology, yo) by putting the actual simulation part on a server and just using excel as a front end. cool times. Anyway, for OSHA content... my partner just told me a crane fell in Ft Lauderdale and killed someone on Friday? How often does that happen?

I heard about that because Elon used his mom's account to tell everyone that a Tesla driver survived that crane because of how great his cars are lol (more that they were super lucky the crane didn't hit above the passengers directly) As for the crane, there's a whole CBS video about the safety violations and OSHA investigation, and the victim who died: https://www.cbsnews.com/miami/news/2-injured-as-part-of-crane-falls-on-vehicle-on-fort-lauderdale-bridge/

namlosh posted:Ha! I've actually got something to contribute to the OSHA thread... My first job out of college was at Smith International, SmithBits division. We made those drill bits, though probably not that exact one. The teeth are typically Tungsten Carbide which yeah, is way harder and more wear resistant than steel. Though if you're drilling through dirt, often the teeth are just hardened steel. The carbide teeth are for rock. If you have to go through dirt and rock then you might change bits once you hit rock, or you might just go with the carbide tooth bit the entire time. Its interesting about the tooth placement if they hit the same spot, but now that you mention it, it makes perfect sense. If each tooth landed in the same spot, it would take way longer to drill the hole too. Lots of guys are getting paid by the foot to drill water wells (that looks to be too small for an oil well) so slow penetration rates = less money. I've seen but never used a PDC bit, by most accounts they're dope as gently caress but IIRC still a bit expensive compared to a tri-cone. Tijuana-A-Go-Go posted:The shaft is hollow with a hole at the end (underneath the spinny bits) and you pump water through it to flush out all the crap as you go Yeah, those look like water/mud jets. Some times they'll use air as a flushing media. But you pretty much got it. Air, water or mud (a mixture of water and various "things") is pumped through the drill rods, out the bit and it sends the "cuttings" (as we call them) up the hole. Though there are cases where a method known as "reverse circulation" is used. In that case, water or mud (never heard of air being used for that) is pumped down the hole on the outside of the drill rods, and then cuttings are flushed up the bit, and through the rods to surface.

Turns out strontium-90 in baby teeth is something of a political downer, and if you want to both prepare to end the world in an orgy of nuclear hellfire AND keep the Moms Against Drunk Driving vote, digging a hole is the cheap option. The holes also let us get much better imaging of the very very early parts of the gigantic ka-boom, which were more useful than 'yerp, sure is a big mushroom shaped cloud all right!'.

Apologies if this was already posted here but I feel it's very relevant: a WiFi-enabled circuit breaker. https://www.youtube.com/watch?v=dd16_Y9xfpw Its remotely controllable via an app which lets you do plenty of dangerous poo poo like remotely cycling the breaker or disabling ground fault and overload protection (Bonus: there's no way to tell if protection is disabled by looking at the breaker)!
