Some 3D Printing Companies Are Taking Action Against Gun Blueprints

Imagine if Xerox controlled what books you could copy the pages of, or if computer makers prevented you from writing certain things. Or Google not letting you read the Bible online.

OTOH there is code in most scanner software to inhibit the quality of copies of US currency. As I recall this was quietly mandated by the Secret Service after a rash of "P notes" -- poor quality counterfeits made by "amateurs" with a PC and a scanner, but "passed" to businesses, perhaps with the assistance of co-conspiring employees. High quality color copiers have had it from pretty much day one.

Does anybody realize that many, many high quality guns were made a couple hundred years before anyone discovered electricity?

This is so stupid. How many milling machines and lathes are there in America?

Well, in addition to all the machine shops in businesses everywhere...how many junior high and high schools are there?

And that's a very real question to ask with respect to the total manufacturing capacity of our nation.

In time of war, these assets will be deliberately impressed into service, including the students in the schools. They have a capacity to train people to use the equipment and to turn out material. Every junior high and high school with shop classes has this capacity. And, interestingly, a lot of the schools were built to codes which would make them easily converted into manufacturing and shipping centers.

All this stuff is such a joke. Even before 3D and 80% all someone needed was some very basic tools to make functioning guns. Not talking zip guns. Talking Sten type guns. They’re pretty much stamped sheet metal and some parts that need to be welded and drilled.
Lathe. Drill press. Band saw. Bench grinder. Welder

In the 90's you could buy a complete Sten gun without the body tube.

How easy is that? All you have to make was a tube. A piece of pipe with a slot cut for the trigger. That's it.

And full auto nonetheless.

That have 'Manual Arts Training' with dangerous machine tools, probably none.

Following the reports on Do It Yourself firearms from Sweden, Australia, Israel, India, etc., I see that automobile jacks are used to press sheet metal for DIY MAC-10 submachinegun receivers and to form magazine wells in 1.5" steel tube for Sten MkIII receivers (after cutting the ejection port). The hydraulic jacks are preferred for serial production.

3D printer gun hysteria, blind to the mountains of low tech DIY firearms.

A Khyber Pass gunmaker can reproduce a gun using a vise and hand tools.

I know Poe's poem was about loss of love or loss of dreams, but "A Dream within a Dream" could be applied to control freaks:
you stand in the surf with a fistful of sand, the sand will escape into the sea no matter how hard you grasp it.
