The stories he tells me are full of poo poo that would turn you white. We've got a goon who drives (or drove) trains for UP that i'm sure can also tell stories...

Alereon posted:...but a sleeping engineer can pretty easily do a simple action like that, like how the engineer in this case acknowledged the alerter. From what I recall from the locomotive insanity thread, the alerter is used so frequently that it might as well not be there. I think some of the guys who work for the railroads said that the alerter goes off for no reason every so often (can't recall the precise time) just to ensure the engineer acknowledges the alerter when it goes off. If it goes off for no reason other than to make you push the button its not that hard to see how an engineer could just become conditioned to push the button when the system squawks and not necessarily know why it squawked.

stizu posted:Companies like Scosche make aftermarket terminals that are meant to add a power cable without it making it look like a kludge. The only problem is that they look sort of gaudy, they are gold colored, and have a plastic housing for some reason. I imagine if you went looking at a car stereo store or website, you might find less gaudy solutions. Not gold-colored, gold plated. It's done because gold is a really good electrical conductor. It's also highly resistant to corrosion, which is probably pretty useful when in an environment like an engine compartment. The plastic housing is a further attempt to prevent corrosion by trying to keep poo poo away from the connectors.

It's also highly resistant to corrosion, which is probably pretty useful when in an environment like an engine compartment. Moreso the latter. Silver and copper are both better electrical conductors than gold, but they're both more reactive. A thin layer of plating isn't going to result in significantly better conductance, especially if we're talking about DC; high-frequency AC likes to stick close to the surface of the conductor, but DC doesn't care about that.

tater_salad posted:How the gently caress does one let their brakes get like this? I mean on the 2nd brake job wont the shop say "time to replace rotors"? We had a dodge minivan come into our shop that was in there only because the "Brake" light came on. It was on because of low brake fluid (Because it was all in the calipers!). Upon inspection, the rotors looked just like that, but oddly enough, the brakes seamed fine on a test drive, not so much as a pull! The metal backing plate was all that remained of the brake pad on that side, and was bent like a banana from heat. Shocking to see something that bad after virtually no noticeable drive-ability issue.

Brake jobs are a conspiracy, I mean the parts are made of metal so there's no way that they would wear out.

Just get used to it. I work on the principal that if you have to tell someone stuff like "Your discs are .120" under minimum tolerance", they're not going to understand and just stare at you blankly. People with any concept of maintenance tend to already be aware, and get stuff done before it reaches the "Oh, sweet Jesus" stage - so if something's been allowed to deteriorate that badly, it would always have been allowed to deteriorate that badly.

  From what i can gather, he got it stuck under a bridge, let the air out of all of his tires to get it unstuck, and figured he would just keep driving until he could find a place to air them back up.

ijustam posted:New 11foot8 vid You know, I wonder how many of these could be narrowly avoided if they put one final overheight sensor literally 5 feet from the beam, and when IT triggered a set of those parking garage up/down tire spikes placed 4' from the beam popped up to forcibly "lower" the vehicle a few inches... It came to mind because it seems most are removed just fine by flattening the tires and pulling.

gently caress. I just let all the smoke out of the Cayman S at the track today. I might be posting some really great photos soon, we'll see. I'm hoping head gasket, but it might be "new engine".

Can you buy 0 gauge gold plated wire? I explained why gold plated connectors are used, which was answering someone that was asking about gold plated connectors. I'm sure some people use them for "mad bling" or whatever other point you're trying to infer, but most people in competition are interested in it for effectiveness first. You don't need "gold plated wire" if it's covered in a corrosion-resistant material (like the shielding all power/signal wire comes in). if water can't get to it, copper works just fine.

It would work, but it's completely unnecessary. There's a big I-beam in front of the bridge that protects the bridge itself. Since most body-job 5 ton trucks are built out of fibreglass and aluminium on top, it's probably cheaper for the insurance companies to fix that up than pay for 6 or 22 new commercial truck tires and a bunch of rims. Not to mention that since it's a 2 lane one-way road, you would inevitably catch some other motorist driving beside the truck who would have fit under the bridge just fine, and you can bet there would be a lawsuit involved there. Plus a hydraulic system and sensor setup would be expensive to install and maintain. The I-beam might just need a little cheap welding every decade or something. Also if you're just giving it the old can-opener, chances are you can tow it away pretty easily. With all the tires gone, it would become an all-day hazard while a tire guy worked on it.

Maybe two tablespoons were it was parked. Couldn't find any on the track, and no one else noticed any either. Top of the engine smells of coolant. We'll see when the local Porsche specialist cracks it open.
