See, what no one in here realizes is that the plan was to use this as a master to cast an aluminum one. Aluminium is a metal, and metal is strong. I’m sure everything will be fine.

Not needing food or shelter anymore because you’re dead is also great for your budget.

Going out with a bang is great for everybody’s budget!

This is called the Jesus nut. It holds the main rotor onto the helicopter. It doesn’t have any redundancy, so if it fails, you’re going to be meeting Jesus in moments.
turmacar@lemmy.world 1 day ago
Thankfully this one is built of many redundant layers instead of just one layer of metal.

I have news for you:
3D printing is very common in the aviation industry by now.
They don’t exactly use TPU and Bambulab printers, though… ;-)SaveTheTuaHawk@lemmy.ca 21 hours ago
Oh yes they do.

To be fair, if you don’t have the files. This is an easy way to make a prototype and fit it, and then if it fits you can order it in metal. This is a cheaper proces in iternating in metal from the start
bizarroland@lemmy.world 1 day ago
If the choice is between being out $1,590 or plummeting to my death in order to save a few hundred bucks, then I’ll just pay the $1,590.
They call it the Jesus Nut for a reason.
SatansMaggotyCumFart@piefed.world 1 day ago
Because it makes Jesus Nut?
shalafi@lemmy.world 1 day ago
That’s what has me grinning! I’m not replacing a Jesus nut with anything that didn’t come straight from the manufacturer.
Ilovethebomb@sh.itjust.works 1 day ago
I’ve actually flown Robinson helicopters, and there’s no nut that looks like this on the helicopter.
So, probably a joke.
captainlezbian@lemmy.world 20 hours ago
Good news is, that part ain’t getting off the ground. Bad news is, the rotor might get kinda fast first
mech@feddit.org 1 day ago
I’d rather plummet to my death.
bdonvr@thelemmy.club 1 day ago
No. No.
For this part? No. You want the real deal. The proper metal. The proper alloy, annealed correctly.
faythofdragons@slrpnk.net 1 day ago
Yeah, but to get there, you need a prototype. There’s nothing wrong with testing the fit using 3D printing before you order a copy in real materials, just don’t put it under any load.
You could print it with normal plastic filaments, but those can deform and screw with the measurements if you’ve got a really tight fit, so metal printing is a good use there.
FartsWithAnAccent@fedia.io 1 day ago
You can also print in different metals with various processes like laser sintering, still though, there are some things you might not want to skimp on: Probably best to stick to approved parts.
rbos@lemmy.ca 1 day ago
It wouldn’t surprise me if such a critical part was cast as a single metal crystal. The stresses on that rotor mist be unbelievable.
TriflingToad@lemmy.world 1 day ago
I’m sure it’s safe if you can do it correctly, but I would not trust myself like that

One time, this was back in my skydiving days so a very long time ago, the drop zone’s CASA 212 was down due to a bad hydraulic pump. The pump finally arrived and the DZO asked me to help him install it. He was a certified A&P, I just had a lot of experience wrenching on cars but it allowed me to get a lot of free jumps due to helping him out on things like this.
He handed me the pump, which was a LOT lighter than I expected and told me with a smile: “Don’t drop it.”
In inquired as to how much it cost and he replied: “$10,000.”
I was holding a pump in my hands that weighed barely 10 pounds that cost more than my car (this was circa 1998 or so).
A couple years later the igniter box on the port engine died and I helped him replace it… That was a cool $15000. The engines were about $250,000 a piece back in those days.

I printed an ABS powerwheels gear out for a friend to test the fit. 100% infill, tt was chonky, was going to get it redone in nylon.
it fit and was ripped to shreds in 30 seconds :)

At 100% infill, it’s all wall. Though the better bet is probably using the printed part to make a mold.

Someone who owns a helicopter but is bitching about spending $1500???
Ajen@sh.itjust.works 1 day ago
People think private pilots are rich because airplanes are expensive. They’re not - they might be upper-middle class (with a mortgage and other debt) but most have to budget their aviation spending. Truly wealthy people don’t fly their own planes, they hire pilots and crew, and probably have no idea what a Jesus nut looks like.
That said, this is obviously satire/bait.
tomiant@piefed.social 22 hours ago
I had to check up Jesus nut, and learned that’s what it’s called because it’s the one you pray will hold because if it don’t you crash. Hahaha
BambiDiego@lemmy.zip 1 day ago
I know the post is a joke but it’s more like “somebody owns a helicopter rental business and they’re bitching about repairs on helicopters they themselves don’t pilot so they themselves aren’t in danger”

JATtho@lemmy.world 18 hours ago
This is a kind of part you want a single metallic-crystal of… anything less would we subpar and jesus. So no uncontrolled cooling of the cast for you. (or the rotor can decide this is a good day for a extra slow spin and no-flight.)

You are ready to own an airplane if you can wake up in the morning, burn a $100 bill and flush it down the toilet without feeling anything.
You are ready to own a helicopter when you can do the same thing, except with ten $100 bills.

This is such a perfect example of why right-to-repair matters: sometimes a “$1,590 part” is really just access. Also, that print looks solid — I’d still check material/heat/vibration limits on a rotor part, but the ingenuity is 💯
