Daily Digest: All the Gun That’s Fit to Print

Today we start out with the logical progression from printed guns: printed bullets.  Actually they’re just blobs of plastic made, like the guns, on a 3-D printer and shaped like slugs to fit inside shotgun shells. But they should be enough to set the MSM and politicians on their ear again. But wait, there’s more! Click through for a video about a 3-D printing system that uses metals like titanium & aluminum that EOS (Electro Optical Systems), demonstrated at IEEE’s MDM 2013 conference. They’re not printing gun parts, but it’s only a matter of time before someone does . . .

And this just in (literally): Liberator 1.1 is available for download at http://defcad.org/forum/index.php?topic=2208.0 Get it while you can!

In other technology, Yardarm has introduced what it’s calling Safety First technology. It will allow gun owners to remotely engage or disengage the trigger safety on their firearms via an app on their cell phone. How long before the po-po want in on this so they can remotely shut down all firearms in a given area, kind of like how they can ask OnStar to kill the engine in a vehicle they’re pursuing?

Should gun manufacturers care who buys their products? The NYT sure thinks so. So what’s next, demanding that GM keep track of who buys their cars and what they’re used for to make sure that no one uses one to transport a car bomb or run down a crowd of hikers? They’re only upset because Gun Makers Saw No Role in Curbing Improper Sales.

While we’re on the topic of ludicrous leaps of logic by the lamestream media, David Whelan of The Guardian tries to turn a story about the Oklahoma tornadoes into a polemic on gun control. His poor logic is exceeded only by his poor taste.

Know any gun manufacturers looking for a new home? Utah wants them. Sen. Howard Stephenson plans to introduce a bill in their next legislative session to reduce restrictions on gun manufacturing and eliminate sales tax on machinery and parts used to make firearms.

Meanwhile in the Centennial State, “a handful of Democratic state lawmakers in Colorado face recall petition efforts in what looks to be the first wave of fallout over legislative votes to limit gun rights.” Blowback can be a bitch.

Skokie, Illinois police Sergeant Timothy Gramins tells why he carries 145 rounds of ammo with him every day – some of it in “high capacity” magazines. If a master firearms instructor and police sniper needs that kind of firepower to protect himself, what does it say for limiting ordinary citizens to 10 or fewer rounds?

And finally, the New Braunfels (TX) Police Department wants to know if you’ve seen the “trailer-load of military grade equipment and ammunition [that] was recently stolen from a New Braunfels storage unit facility. The trailer was full of military uniforms, AR-15 magazines, various ammunition, military grade body armor, and a compound bow, among other items totaling nearly 4-thousand dollars in stolen equipment (including the trailer).” We’re guessing that ammo may be long gone, but if you’ve seen any of it, you can call them at  (830) 221-4100 or (830) 620-TIPS.

    One question about the last story. Why the hell did the cops have a compound bow in their trailer?

    1. avatar Shenandoah says:

      Some states have an extended archery-only dog season.

    2. avatar Russ Bixby says:

      I believe the stuff was privately owned.

      Still is, except for that whole possession being nine tenths of the law caveat.

      1. avatar Tom in Oregon says:

        $4,000 dollars including the trailer?
        Was there a half case of ammo in there?

        1. avatar Russ Bixby says:

          Hmmm… Maybe thats what he paid for about a zillion rounds of 7.62×39 milsurp before the drought.

    3. avatar Don says:

      Compound bow is for Zombies of course.

    4. avatar Ropingdown says:

      The compound bow was for shooting cats. That was before they switched to crossbows, which require less training and skill. It’s just the same old dumbing down of jobs to reduce personnel costs.

  2. avatar SelousX says:

    Yay! Just downloaded the Liberator plans. For posterity’s sake, y’know…

  3. avatar Gtfoxy says:

    Wait! Arent po-pos around the country using plastic bullets as a “non-lethal” option?

    So what’s so wrong with the fact citizens, other than those employed by corporate entities (“cops”), can make & use them?

    Does anyone else hear the song “Bad Boys, Bad Boys…” in their head?

  4. avatar Russ Bixby says:

    Rubber bullets can kill, but it takes precision.

    Now, when the “printers” start using chlorates, permanganates and carbon in their feedstock hoppers…

    1. avatar APBTFan says:

      Chlorophyll, pomegranates and carbohydrates? Sounds like hippy food in high velocity pill form.

    what is truly needed is a garage build method for making primers, they seem to be the most complicated part of a centerfire firearm.

    1. avatar Russ Bixby says:

      I’ve made percussion caps. Primers are similar.

      Here’s the quick and dirty on blanks:
      – get a cutting punch that’s about 30% wider than the primer is to be;
      – make a hole in a piece of temperable steel (600°/water quench) the outside diameter of the primer, about 3/8″ deep, then drill a centered 1/8″ hole through to the back;
      – use a countersink bit to cone out the top of the hole to the width of the cutting punch;
      – round the cone/bore transition with a Dremmel, Foredom, whatever;
      – make a round punch 3/64″ narrower than the hole, with a slightly rounded head, out of temperable drill rod;
      – heat both the block and rod to 600°, then toss ’em in water;
      – anneal some 0.020″ brass sheet with a propane torch, then go to town with the cutting punch;
      – place a disc in the cone, center the rod and hammer it into the bore;
      – use a 1/8″ pin punch to tap the blank back out of the bore from the rear;
      – if the extraction dings the blank, use the forming punch to make it nice again against a block of lead;
      – repeat with more discs.

      Next, cut the blue bits off a bunch of Ohio Blue Tip strike anywhere matches, mix with a tiny bit of water and grind into a thick paste.

      Fill the blanks half full of the mixture and let dry for at least 24 hours in a sealed container with a small dish of calcium chloride (hardware store – it’s called Damp Rid) to suck up all the moisture.

      Set the primers open side down on a cookie sheet and spray ’em wih Pam non-stick; spray a nylon cutting board as well. Do not use a cutting board belonging to your spouse.

      Roll out some Epoxy Putty or Magnum Steel (auto parts place) between the cutting board and a sheet of waxed paper; get it down to 1/20″ or less. Using your spouse’s rolling pin is O.K.

      Peel the waxed paper off the board; the epoxy should stick to the paper. Lay it down, epoxy up.

      Press the primers into the putty, so that the open part fills up with epoxy. When the sheet is full, turn it over and use the forming punch to gently push the epoxy further into the primers.

      When the epoxy is fully cured, break up the sheet and scavenge the little brass lovelies.

      Voila!

      1. avatar CarlosT says:

        Nice, Russ. My next question is what do you do if you can’t get those matches anymore? That is, what’s the recipe from scratch?

        1. avatar Russ Bixby says:

          Then use silver fulminate. The recipe is readily available on line.

  7. avatar Hryan says:

    Just out of curiosity, ain’t a 3D printer that prints in titanium and aluminum basically just a CNC machine?

    1. avatar DP.science says:

      No, one can be used by an inexperienced home hobbyist of limited means, the other is a 3D printer.

      1. avatar Russ Bixby says:

        Nice.

      2. avatar Billy Wardlaw says:

        A hobbyist with the right equipment can also use CNC. I did it in high-school in the 80’s when it was still fairly primitive.

    2. avatar Russ Bixby says:

      A CNC machines blocks of material. An additive sintering modeler ain’t that.

      1. avatar Human Being says:

        One adds, one subtracts.

        1. avatar Russ Bixby says:

          I thought that was what I said… 😉

      2. avatar Ropingdown says:

        Why view it as an either/or choice? Each has its role in the hobbyist’s workshop.

        1. avatar Russ Bixby says:

          I don’t. I was just answering the question asked by Hryan.

    3. avatar Billy Wardlaw says:

      No. CNC milling is a subtractive process using melt-poured, and possibly forged material blanks, and 3D printing is an additive process, that is either printing in a melted, or UV cured material, or a metallic powder laid down in thin sheets and laser melted and fused.

      The former is significantly stronger than the later, which is why working parts are generally CNCed and prototypes are often printed to test fit and function.

  8. avatar Nigil says:

    The story of the shootout with the Skokie cop should be enough testimony to get every mag limit thrown right the hell out. Perp was hit so many times, a NY-compliant gun would have to be emptied, reloaded, and emptied again, without a miss, before he went down. Against one single assailant, who was stone cold sober. Hey New York lawmakers (and every other mag cap limit pushing jackbag)…FOAD.

    1. avatar JAS says:

      +1

      Excellent article. Interesting that he switched from .45 to 9 mil to carry more ammo…. Guess he learned something after hitting the perp 14-times with his .45.

    Great post Frank, wall to wall good stuff, Randy

  10. avatar APBTFan says:

    MSM and ignoramuses will wet their pants and make all kinds of press at the thought of a 3D printed bullet yet know nothing about Brenneke SF Short Mags.

  11. avatar DaveL says:

    A 3D-Printed plastic bullet? Come on, casting lead bullets isn’t exactly rocket science.

    1. avatar Lucas D. says:

      That’s what my thought was. You know what else is “terrifyingly easy” to load into a shotshell? Pennies, nails and rocks, and those can be downright devastating to a soft target. If they’re worried about us making our own shotgun ammo with homemade ingredients, too bad; that ship sailed about 400 years ago when we invented the blunderbuss.

    Ha. Gun-free zones work about as well in Venezuela as they do here:

    “…the logical progression from printed guns: printed bullets. Actually they’re just blobs of plastic made, like the guns, on a 3-D printer and shaped like slugs to fit inside shotgun shells…”

    Gee, I have been doing that with lead alloys, a casting pot and bullet molds for 50 years. And my .45-70 cal, 520 grain cast bullets will go through about 18-24″ of ponderosa pine without much trouble. Haven’t tried to make shotgun slugs, since the .45-70 has a bit better range.

  14. avatar Billy Wardlaw says:

    Not a very good print application. Casting lead is easy and there was ZERO reason to print the interior as a lattice – the only reason that is done is to save on material and/or weight, which is stupid for a bullet.

  15. Currently it looks like WordPress is the preferred blogging platform available
