I actually did go to Alcoa High School, and the football team took the shop room over in 1997 and turned it into their weight room. Shop just kinda ceased being a thing. I did get to take woodworking as a freshman in '96. There hadn't been any metal shop in several decades.

Having churned butter, used a washboard, mowed hay by hand, etc, I'm perfectly happy having done it ONCE and having to get good at it. This goes about triple for having cut down a 30" diameter maple with an axe. That's a thirty- to ninety-second job with a chainsaw if you know what you're doing. It's a couple of hours with an axe if you don't. As for content: Oil fitting on the back of a jet engine had a brazed elbow that became unbrazed at some point, leaking oil past the hot section. It leaked down the back of the fitting, forward through the shrouds, down the engine, and pooled in the heat shield. It looks like what happens when you leave tupperware in the oven. That last image is a 7/16" bolt, half obscured by the pile of goop.

I'm still pissed that my landlord's stooge filled a cold air space with water pipes running through it with expanding foam rather than hiring a drat plumber to install a valve and draincock so I could just shut that sink off in the coldest parts of winter. (flippers added a first floor half bath before selling the house to the rental company and of course did a poo poo job). It obviously still freezes when the temp gets below about 5F.  all around.This is cool.

How can a person survive without knowing how to do anything? I worked with a guy once who would call a plumber every time he needed a tap washer done. Not because the seat needed grinding and he didn't have the doodad or anything like that. Just the washer.

A lot of engineers... it just gets to where they don't know any better. Or I'm seeing somewhere with some of our projects where the 3d model is a couple kludges piled on each other and some features literally can't be changed without crashing the CAD program. It's really weird.

Because holy gently caress do people make some dumb design choices. Been saying this for years. At the very least a "just because you can design something this way doesn't mean you should" unit as a part of the classes engineers take. School shop chat: took two years of metal shop, my high school had mostly manual machining equipment - lathes and milling machines, an aluminum foundry, gas forge and stick and oxy acetylene welding. Second year they acquired a little tabletop CNC lathe. This was in the late 90s/early 2000s so anything CNC was a big deal in a public school. Most memorable part of the class was the teacher almost exclusively playing old Roger Miller records during class. Geoj fucked around with this message at 19:00 on Dec 8, 2017 |

we're well past the point of mass produced products having any one single person decide where a particular component goes...it's not going to come down to one lonely engineer designing a battery box who's never turned a wrench forgetting that maintenance is something to be considered in the design.

The software engineering side of this is the similar "Engineers should not be allowed to build interfaces." It may work perfectly but if it runs like an engineer built the interface generally you are hosed. This explains most of the horrible user interfaces you have used.

Depends on the mass produced products. I can trace a lot of issues with mass produced generators from my company to a bad design that one engineer forced through 4 years ago.

I'll give you an example. Aero engines often use taper-fit bolts in certain applications - the effective diameters vary, but the taper angle will basically be the same on every single application. I had a drawing for a bolt come across my desk, which had a different taper, so I questioned it. It got to the point of having a conference call with half a dozen engineers from the engine company (who shall remain nameless, but there's only so many of them), everyone having insisted that if it's on the drawing, it must be correct, and I had to point out that maybe someone could go and look at the drawing for the hole it fits into to check, because I can't see them magically conjuring a different taper out of thin air just for one bolt family. Hey, guess what, it should be the same angle as every other taper bolt ever made, who'd have thunk it.

What is a tap washer and why are koalas being mentioned? Is this jargon? Reference: I own(ed) a lathe and welder and do a lot of both redneck engineering and by-the-book torque speccing. I even have special torque wrenches for each range to ensure accuracy. However, I'm not above welding the rivets in an Ikea/disposable shelf to temporarily fix wobbling for a few decades.

Dunno, but that's what happened when I changed a rubber dome seal washer on a burred and corroded hosed up seat before. Ex just kept on tightening the tap more and more each day because it keeps leaking and dripping. I did not care because it was a rental house and the seat wasn't my problem and besides I'm moving out. Fo3 fucked around with this message at 13:19 on Dec 9, 2017 |

At least once a month I have to replace a cartridge and seat in one of the sinks in the dining hall because the idiotic fucks they hire to work in there think the only way to turn off a sink is to jam the handle with full force to the rear until they strip out the loving brass cartridge inside (and not just where the handle attaches, oh no I've seen them literally rip the threads for the stop out) and/or drive the seat through the washer. Every month.

No. 6 posted:That chipped a valve and its seat? I think the owner overheated the engine, he claims he was trying to do burnouts (something you really can't do well in an Audi Quattro, which is why most guys do donuts), and the #5 cylinder is notorious for getting hotter than all the other cylinders and killing exhaust valves.
