Did you know 2016 is the Year of Building Your Own Gun? It is. Get to it!
OK, here’s a new video on printing and assembling the Bolt lower, a bolt-together AR lower.
We’ve featured the Bolt many times before (including links to its files) but this is a new video. The names involved (Ma Deuce, RollaTroll, FOSSCAD, FP [Freedom Print]) should be familiar to everyone.
The Bolt looks like it easily would be modified for assembly with rivets, if you don’t like the idea of parts unscrewing themselves. Several mods of the Bolt already exist, like one by Warfairy adopting the profile of the Vanguard lower, and dispensing with any provision for a safety.
Homemade Charger How To
If 22 is your thing, here’s an Instructable (!) on doing a pistol based on the Ruger Charger design.
The creator is another old familiar name, Buck Ofama. Sounds vaguely foreign; do you think that’s his real name?
Reminder, Here’s the Latest File Repository, “Ishikawa”.
Can’t go the mile if you ain’t got that file.
Some New Stuff — no Files yet
Ambi mag release for the Glock-mag Gluty pistol, based on Glock and AR parts.
Treillage (sp?) competition stock from Warfairy — gives lots of adjustments on a regular carbine receiver extension. How it looks on the gun:
How the parts break down, color coded:
Bear in mind that anything that’s still just a rendering, puts you on the bleeding edge of the tech when you go to print and use it. But for some of us, that’s half the fun!
New Videos from Guy in a Garage
We’ve already seen GiaG print, remove support material, and assemble a Vanguard AR lower in ABS plastic. But he’s been on a roll lately.
Here, he takes the Vanguard to the range — 300 Blackout with his homemade suppressor. (He blanks out his suppressor markings for privacy. Not that “they” don’t know, as it’s a registered receiver). After firing 60 rounds at the range, he analyzes the condition and performance of his lower.
Want to make your own suppressor like he did? Here he covers the regulatory issues.
He has printed at least three different AR lowers. Here he preps and assembles a Phobos, in ABS:
Here he preps and assembles a Charon, again in ABS:
Important note, he previously printed an early model and it was “off” dimensionally — this one is the 4.0 version.
And here’s a range safety bolt/chamber block for the AR. If printed in nylon, these would be oxen strong and easily dyed orange…. unfortunately we don’t know if he has released the files.
Some of these accessories are cooler than entire 3D Printed guns.
Case Trimmer Insert
Reloaders swear by the $70 Little Crow Gunworks’ WFT — World’s Finest Trimmer. The WFT2 version lets you use the same trimmer for multiple calibers with a $30 interchangeable insert (instead of a whole second trimmer). So Guy in a Garage printed his own insert for the WFT2 for .300 Blackout. This video shows it and tests it out.
Is this the first Registered 3d Printed Firearm?
Michigan has some weird laws. (Every state has a few). So the guy who made this Washbear is arguably the first manufacturer of a registered 3D Printed firearm, unless some poor wretch in the People’s Republic of Massachusetts, the Cosanostrian Emirate of Cuomostan, the Alternative State of California, or some other dystopia has done so already.
The cylinder has lined chambers, and is printed of Taulman 618. If you look closely, the pistol unlike the standard Washbear, has a frame made in two parts and joined by screws (and glue). That’s because this builder’s printer wasn’t big enough to print the whole Washbear frame in one shot.
The whole Imgur thread is worth reading in depth, as almost every picture has an informative caption. Enjoy!
How about some Tech on Carbon Fiber filament
Is “carbon fiber” and other exotic filament for normal FFF printers really that much stronger? Joe Binka, Lead Design Engineer for large-format-printer maker 3D Platform, wanted to know, so he did a very engineer thing and, making a test coupon and testing the coupons to failure, evaluated all the extra-strength filaments he could get his mitts on. (3D Platform’s printers use the same FFF technology as all open-source FFF printers, and can use all the same materials). The results were a little surprising.
In this color map, redder is better and greener is worser. Joe discovered that while polycarbonate was the strongest, it was such a pain in the neck that he recommended the runner-up, PC ABS, instead. Polycarbonate…
is a pain to print with. It warps and curls really bad and I would rather avoid it if possible.
…. If I need a really strong material, I’m going to go with the PC-ABS over the carbon materials. It’s just much easier to deal with.
Joe has promised to add new materials to the chart, as they crop up.
