FedEx won't ship milling machine that makes untraceable guns

You mean a CNC mill just like any other CNC mill, which have been around for ages? What’s next, lathes and end mills?

Not too surprised at this; thanks for ‘how to satisfy my curiosity about’
Love ya’ both

Google “lathe accident.” They don’t need to be trying to make a gun.

Anyone who isn’t slightly terrified when a lathe is in motion isn’t thinking too deeply about the forces involved (I have a lathe in my garage).

Don’t wear your tie (or have long hair) in the machine shop.

When we were first being introduced to the lathes in the shop at university, the guy in charge told a story about a guy with long hair…

And also one about a guy that tried to wipe a mark off the lathe while it was spinning. That didn’t end too well either.

My hair on occasion:

I have a (drunk) (sorta) friend who tried to touch the freight train as it was roaring by him in Russia. He only lost the tip of a finger.

No thanks.

no other part of a gun is regulated (for the most part), so if you were to buy the other parts and get the cheapest parts you’d probably end up about the same as buying a bargain bin equivalent or maybe even more, since the rawer castings this is designed to machine are usually more expensive than the finished “firearm” regulated ones.

That’s some false equivalence you’ve built there. Must have taken a lot of work and some experience with hardened tools.

Google images for more gore.

The big machines are Seriously Powerful, and the amount of kinetic energy stored in a large spinning workpiece is downright ass-puckering.

Such warning label would be quite justified:

It’s machines all the way down.

Edit: Just wanted to add that what FedEx probably fears is that some ‘gun-nut milita member’ is going to run off 100 untraceable weapons for use in the revolution. Because that IS scary.

Yes one of these people. … … Oh wait. Who is who?

The reason why it was written; shall not be infringed.

Choose your poison my friends.

Mills and lathes usually weigh over their 400 lb. limit. most decent CNC mills weigh many tons.

I doubt it. For a little more than that you could buy an inexpensive mini-mill and convert it to CNC. Then you could mill useful stuff, not just gun parts.

The 150 lb lathe I had delivered certainly didn’t.

My hackerspace has a mill from above (and my lathe is from there). They aren’t huge but they are good enough for 90% of what people do, including lower receivers. We also have much larger lathe but I’m still not sure it weighs more than 400 lbs as I’ve helped move it.

Our giant CNC router took six of us to move down the hallway but has historically mostly been used to make guitars and boxes.

Which is exactly what we did at my hackerspace.

We got one of these and then a CNC kit for it and added a computer to control it:

I was thinking more along these lines for objects with deceptively high inertia:


I=mr2 It’s the law

I’d rather say
E=1/2 Iω2
Because the thing that ruins your afternoon is not the inertia itself but the energy it carries.

Or, even better,
E=1/2 mr2ω2

The two squares there add the right one-two punch.

(Also, the preferred picture would be a less-detailed line-art. That’s good for high-res lithography but lower-detail monochrome processing would lose a lot. Is there any such good one of Newton?)

Hey man, I just slapped it together in 5 minutes with Paint.NET. Google was giving me a hard time finding a crayon drawing of Newton that actually looked like Newton, and that was the best I could whip up on such short notice.

Also I’m a technician. Not an artist.
