Gah! I need to know whats causing that noise, my buick was making a sound similar to that while driving it to the junkyard. Experience has shown if you drive long enough that noise will go away and you will suddenly have very little power.

A lot of the things we safety wire would never come loose even with excessive vibration, but the TO says to do it

If I had to guess he is referring to a lot of the dye-based penetrating chemicals they use to non-destructively test parts that help locate cracks under UV light. Having a UV tattoo in that field would be a bit of an inside joke.
Yeah. NDT at our place is generally flourescent penetrant (ASTM E-1417 is a pretty common standard for us), but for ferrous material we'll also use magnetic particle inspection (ASTM E-1444, for example).

If you're going to be about it, NDT is of course any test that doesn't cause damage, but we specifically use the term to mean crack testing.

How does this even happen? Just gets that weak after tons of heat cycles? Sucking up rocks and poo poo?

Well, it was my old turbo.

I had a high end tune on the car, one that was at the limit of that turbo. I had the stock airbox setup (which is purported to be good to 400HP w/o becoming a bottleneck), so I kind of doubt that something got sucked in there.

It had a lot of shaft play, and I think that it was just spinning really fast and ground itself down against the housing at some insane RPM (like 100K RPM or more, these things are crazy fast).

It didn't even smoke very much when I decided to remove it, just a small amount when I would first start moving.

Unless your compressor housing is made out of unobtainium and is right below diamond on the Mohs scale, this doesn't seem plausible.

I loving hate pitot tubes. We have to run an extension on them when we install our camera system, the extension sits right at SLAM YOUR loving EYE OR FOREHEAD INTO IT level when looking at the camera.

Also loving pilots not turning off pitot heat (melts the rubber extension tube) and I put my hand on it and BURN THE loving gently caress OUT OF MY HAND.

Needless to say, getting off an end user or major supplier's poo poo list is rather hard work, so you don't gently caress around.

Yup. It sure will.






Although this isn't duct tape as you know it - it's made of aluminum for one, and the adhesive is extremely strong (and waterproof). In the industry, it's known as speed tape (or 600 mph tape, as it's supposedly good up to that airspeed).

We end up speed taping something every other day, it's quite common on the line. It comes off relatively clean compared to say, duct tape. ISTR it being about 80 bucks a roll?

We once speedtaped an entire wing to body fairing on an A340 to stop a buzzing sound in flight; the aerodynamic seal was worn and flapping against the fuselage.
When the pilot was doing his walkaround, he asked "WTH is that?!?", to which we replied, "Your wings are falling off, mate".

Those pics of speed tape around windows are probably from a windshield change with no time to let the sealant cure. It's permissible to apply the tape over wet sealant so the plane can get out of dodge.



I always thought MEK is illegal in the USA? It's a staple in Canadian hangars; the old timers used to wash their hands in the stuff (and died young)

Slung Blade posted:

Local hardware store should have it. It might be sold as Butanone. It's basically acetone with a methylene crammed in the middle. For cleaning solvent use you can think of it as a more aggressive acetone. It eats just about anything gummy, sticky, etc. Latex dissolves almost instantly on contact. Disposable nitrile gloves break down more slowly, but work in a pinch if you change them frequently.

We use MEK a bunch on my dads boat, and he always told me that it absorbs into your blood stream through your skin and will gently caress up your kidneys. Not sure if its true, since he told me that when I was using it to clean paint off my hands(I was around 12 at the time),but it wouldn't surprise me. And why did I have paint on my hands? The MEK dissolved parts of my gloves.

When I installed terrazzo floors, I worked with a poo poo load of xylene, which i think is worse than MEK. I worked 1 day mixing without a respirator and ended up getting sick as gently caress from the fumes. Granted I had a 55 gallon drum of the poo poo sitting next to me, but god drat that poo poo is nasty. That job prolly took a couple years off my life. I wish I took pictures of the big propane floor grinder we used on that job site, it was a mechanical failure waiting to happen. About 4,500lbs riding on 12 1" around cylindrical diamond stones, was made in the 70's and was definitely behind on maintenance. There was a bigass lever to engage the motor and start the stones spinning, but you couldn't reach it while holding the handle of the thing. There was a art of pulling the lever and really quickly getting back onto the handle before the whole thing took off. And the whole time your standing in a 1/2" of water. I had one of the little(~850lbs) floor grinders get away from me once and it took out a good chunk of drywall before I got to the power cable, I don't even want to think what one of the big ones would do.
