MetalWorking Gun Making

So someone was able to 3D print a plastic gun and is shot a few times... Why not make guns from metal? The most specialized piece of equipment I can think of would be for rifling the barrel. Years ago I had a "Foxfire" book on gun making, it had simple cutters and a guide that turned at the right twist. It also wouldn't seem that difficult to do button rifling with the carbide "football" of the right caliber.

Iggy did a reasonable cost linux CNC conversion of a Bridgeport that he got with bad controls and he was even able to add a 4th axis. Seems a gun could be designed so all parts could be machined on a 3 or 4 axis mill plus a lathe. It wouldn't be as easy a pushing "Print" for a 3D gun design, but at least the high stress parts could be machined from metal.

I don't know if the assault weapons parts sets will still be available, seems if we just had to machine a receiver it wouldn't be too bad, especially if someone already had the CAD/CAM model available.

Better hurry up before Obama outlaws metalworking!

Roger, if I was not so busy, I would definitely try to make an AK receiver on my Bridgeport, it is fascinating stuff. The rest can be bought without any licensing.

I explored making upper and lower recievers from a 7075 hogout a while back, got the federal paperwork and so forth but in the end I decided that the profit margin is simply not there.

Let me know if you want a.DXF wireframe.

Why use a mill? AK's are about the easiest receiver to make there is.

Stamped steel bent into a U shape. You can buy a flat or make one easily. You start with 1mm (.040") 4130 steel sheet. Fold it up, install the trunnions and rails. Bingo you have a receiver.

Lots of infor on gun making on YouTube

The methodology of the left has always been:

  1. Lie
  2. Repeat the lie as many times as possible
  3. Have as many people repeat the lie as often as possible
  4. Eventually, the uninformed believe the lie
  5. The lie will then be made into some form oflaw
  6. Then everyone must conform to the lie
