GotLag posted:Just what degree of protection would that offer? Would it provide any protection for a blow heavy enough to break it? Well, technically that is a helmet. Practically, since it does not seem to divert the point of impact away or around the entire covered surface, it only protects from things that are piercing or projecting force which can be stopped by a clay vase.So technically same thing as with the leather-built helmet from the pre-WW1 era. But it does protect your hairdo.

This happened at a building I used to run, but the opposite direction. The night cleaning crew put a backpack vacuum on the elevator and then moved to unplug it, but they were too slow. The elevator doors closed and the car went down, pulling the cord some ways before getting to the plug which caused the vacuum to smash into the elevator ceiling. The plug end broke and the loose wire in the shaft snagged in the door hardware and the elevator car got stuck between floors. The best part is they didn't mention this to anyone. I got to work in the morning and found an elevator out of service. I called our mechanic who found the car location and opened the lobby doors to reveal 20 feet of SJ wire tangled in the door operator. We looked at each other and just sighed. I had to tell the night cleaning supervisor to have the "poo poo happens; I won't get mad, just tell me when it does" talk with his people.

Hustlin Floh posted:There wasn't a single one that shattered. Maybe I'm a talented retard at crashing but it was exactly what happened to me? I mean, the one time I went head over handlebars the autopsy of the helmet showed that it split lengthwise with some serious deformation of the styrofoam, while the plastic liner on the outside took the abrasion and held the chunks together. Its not like it exploded into styrofoam confetti but it did deform and break to spread the impact. For me it was a good example of why you replace your helmet if you ever properly hit the ground with it. Trambopaline fucked around with this message at 02:58 on Dec 29, 2017 |

The hard styrofoam (EPS) bike helmets are single use and designed to fracture with a significant impact. On a hard crash they will really break, though the plastic shell often holds them together, but they can explode dramatically too. There are also multi-impact helmets that use polypropylene (EPP) or other softer materials that shouldn't break apart. They're often sold for use in sports where you're expected to fall.

Trambopaline posted:Maybe I'm a talented retard at crashing but it was exactly what happened to me? No, I misunderstood you. I thought you meant they were designed to burst, but yeah, what you said is right. The deformation of the foam is the intended effect, but there's usually a bit of cracking as well. The manufacturers recommend you replace your helmet every 3 years to prevent the foam from becoming too brittle, because they'd rather it get mushed instead of cracking. (Also because they want your money) Edit: In order to actually contribute more than just a petty jab, the big debate over the past few years in bike helmets has been "MIPS", the Multi-Directional Impact Protection System. (http://mipsprotection.com/) It's basically a plastic sleeve that gives you an extra slip-plane and increases the moment of impact. When I was doing training at one of the big bike company HQs I got a chance to sit down with their helmet designer and asked his opinion on MIPS. He said it was total bullshit, and that your hair and scalp already provide a slip-plane that the tests don't replicate (the test is cinching a helmet down tightly on a metal head then slamming it on an anvil). It was an interesting take, but less than a year later that guy's company was offering helmets with MIPS. I never figured out if he changed his mind on it, caved to pressure, or got replaced altogether. Hustlin Floh fucked around with this message at 04:15 on Dec 29, 2017 |

I've never heard of anything safety related but early replacement due to gouges, sagging, or joint stress because at a certain point wall thickness recommendations landed on points where the designer is assuming this bullshit is happening but its terrifying because is usually a leading indicator on bullshit like how much attention is really being paid to flange torques or tool removal hygiene.

IPCRESS posted:Fill your copper pipes with finely ground salt ($0.90/kg at Woolworths) when you're shaping them (unless you have a proper mandrel, then use that). They'll still kink if you're determined, so keep that in mind. Really don't use soldered or sweated joints. I ended up making a mandrel bender. I'm using stainless steel for the whole build, no copper. Tried a few experiments with bending - had a few kinks on tests. So I filled the pipe with sand, filled it with water, and hammered plugs on the end. Then I got a torch out and as I bent, kept the steel red hot - worked a bloody treat!
