Depends on how much effort went into reverse engineering the part, but most likely when tolerancing enters the conversation. Most machine shops aren’t able to hit those tolerances and would laugh you out of the shop.
A shop that can hit those tolerances will kick you out of the shop; there’s a good chance they already work in aerospace. They have a deeply vested interest in avoiding the accompanying FAA inquiry should it be installed or, Satan forbid, actually flown.
A non-aerospace shop capable of meeting those tolerances would start laughing at the desired price point. Purchasing a suitable blank alone would cost over $1500, much less cover the actual machining.

Aerospace manufacturing is fucking wild and is a rabbit hole worth diving into if you’re looking for some of the finest engineering porn humankind has to offer.

If an aerospace engineer made one of these he would no longer be an aerospace engineer.
Everything else you said is correct.

Aerospace manufacturing has a paper trail longer than you can imagine. The company selling this part can tell you (well, the FAA) the exact ingot out of the foundry and every single process and every person who has touched it since then.
No machine shop will take this job; the moment this guy is unable to produce a serial number and paperwork from the real manufacturer (likely during preflight if not installation) the FAA will track down the owner of said shop. At best that owner will lose their business and pay a massive fine, at worst spend a good long time in prison.
The FAA doesn’t fuck around and for that I am thankful.

A few weeks ago I ran into a guy wearing their masturbating nun/Jesus Is A Cunt t-shirt. I learned of that legendary shirt a long time ago and finally seeing it in person made my night, at least until Fallujah and Entheos blew me away.

This song/album fucking rules. I’m also partial to Monarchy, but Owls kept me company during dark times both literally and figuratively as I was working 3rd shift at the time.
- Comment on Made in space? Start-up brings factory in orbit one step closer to reality 1 week ago:
Not stupid at all, that’s an excellent question! I’m not privy to the details of this furnace satellite but I have an idea or two on how I’d approach the problem. Pure (somewhat educated) speculation ahead.
Firstly, you mentioned nonconductive materials. Insulating material isn’t perfectly nonconductive but can get pretty close. I’d imagine combining insulation with the vacuum of space would limit conductive heat transfer between furnace and the other equipment.
Insulating and limiting the conductive transfer of heat doesn’t eliminate it though. You’d still need an active form of transfer to shed the heat. I’d investigate the feasibility of a convective heat exchanger; use coolant to transfer heat from the furnace to a radiator.
From there I’d study how the James Webb Space Telescope maintains equilibrium. It uses a reflective shade to shield the radiator from the sun but I lack specific knowledge of the design. The temperature difference between hot side and cold side is a driving factor in heat transfer; maximizing the difference between the two leads to more efficient, effective control.
Honestly though, its been a few years since my senior heat transfer course. Radiative heat transfer in the vacuum of space is Master’s if not PhD level specialization. I’m not at that level yet, so please take this answer with a large block of pink Himalayan salt.

Harry Potter was such a crucial part of my child and teen years. I cried when Dumbledore died. I read several of the books over a dozen times, and did an annual reread of the whole series for awhile.
I’m not trans but that TERF cunt will never see another cent or good word from me. I spit on her name as she spit on my childhood. Solidarity, friend.

Hah! My adoration of partial differential equations is far purer than even physicists could hope to achieve.
- Comment on Made in space? Start-up brings factory in orbit one step closer to reality 1 week ago:
There are three modes of heat transfer; conduction, convection, and radiation.
Conduction happens when two bodies at different temperatures come into contact with each other. The total heat transfer depends primarily on the difference in temperature, contact surface area and time spent in contact.
Convection takes place when a fluid (I.e. a gas such as air or a liquid such as water) comes into contact with another body. Here, again, heat transfer depends on difference in temperature, contact (“wetted”) surface area and time in contact which is primarily dictated by how fast the fluid is moving over the body.
On Earth we generally leverage these two modes. An example of mixing the two modes is a CPU heatsink and fan setup. The heatsink conducts heat away from the CPU and is (usually) distributed throughout several extended surfaces I.e. fins. The fins increase the surface area in contact with air, enhancing the rate of heat transfer.
Now, we can’t really take advantage of those in space. The lack of an independent physical medium means the heat ultimately has no where to go; this is known as a “closed system”. So if we generate or store enough heat in a body subject to the void of space without promoting radiative heat transfer, that heat will more or less stay put.
Radiative heat transfer is fucked up. Everything above absolute zero radiates heat. You mostly can’t see this exact for one glaringly obvious example; the Sun. Sol is so fucking hot that it heats the Earth through the vacuum of space purely via anger aka photons. And thanks to the miracle of science, you radiate anger right back at it.
Explaining radiative heat transfer further is outside the scope of this reply and will be left as an exercise to the reader.
I hope I explained this well enough for you or other readers to impart a ‘basic’ idea of a complex engineering discipline that I adore. I’m absolutely willing to answer any questions.

At this point I’d nearly appreciate the removal of old.reddit or RES. My desktop browsing experience hasn’t changed in roughly a decade and a half and that’s a shitload of inertia. A few trims of my subscribed list has limited my exposure to the worst of the slop and botting.
Mobile is absolutely a different situation for both Reddit and Lemmy alike. I found Jerboa shortly after the API disaster and have stuck with it since, but I probably need to look into tweaks for desktop/browser Lemmy. RES and old.reddit are a killer combo but fuck their ‘official’ app and the ‘new’ interface.
Regardless, I no longer participate on Reddit and highly prefer interacting here; more interesting and informative conversations by far.

Keyboard and mouse input for the phone is a gamechanger for me. Having a manipulatable window that I can drag and drop files to is super nice as well.
Also since Slay the Spire doesn’t have cross-saving and all my progress is on my phone I can play it without staring at my phone.

I agree with you in spirit but would also like to shill for scrcpy in general if you aren’t already using it. Mirroring phone screen to my laptop is fucking amazing.

Totally valid, no rush. My guitar whispered to me a bit yesterday but its been a few weeks so I stuck to warming up rather than pushing for tempo.
I’ve mostly been working on Black Dahlia Murder’s Statutory Ape and Protest the Hero’s The Dissentience in terms of full songs. A few scattered PtH riffs off Palimpsest; intro to Sun of Nothing and the sweeps at the end of Selkies by BTBAM to round things out.
Haven’t written anything in years, just working on my chops.

A few more;
Alluvial
An Endless Sporadic (Guitar Hero fans know)
Scale the Summit (but only the first couple albums - Carving Desert Canyons specifically)
TRAM (Tosin Abasi plays jazz)
Teramobil (GREAT introduction to my favorite modern bassist, Dominic LaPointe)
Trioscapes (Between the Buried and Men’s bassist Dan plays jazz)

I often can’t work to their music because my brain fills in their vocals for me, which is sometimes too distracting.
Can relate 100%. I have audio processing oddities that make understanding lyrics difficult. With how many times I’ve listened to their albums (1500 times in a row for Palimpsest! I’ve got the Last.FM receipts for it, even) I know the lyrics mostly by heart. Instead of my brain being distracted trying to comprehend it gets distracted trying to sing along. Thus, instrumental for getting work done.
Also I can’t keep my boys Between the Buried and Me out of this post any longer. Suuuuuuuuch a fucking band. The new album rules, too!

CHON, Covet and Mestís are pretty laid back and so fucking excellent.
Cloudkicker has been around for a long ass time; early-mid 00’s on Myspace. One of the progenitors of the ‘bedroom guitarist’ project, although he toured with Intronaut as his backing band awhile back.
Arctopus and Blotted Science are fucking weird and I love them.
