addictive manufacturing edition

post project, tips, questions

here is a 3d printed magazine for an old broken pistol i got cheap

and here are some snap caps for 22lr, 9mm makarov and 7.62x39

if any of you have a PMm profile grip (if possible based on the bakelite grip with the star), i have a mp654k and a PM, and want to install a PMm (like the mp654k) on the PM, as the grip is a bit too slim for my hand and to shoot confortably

Cooking again.

I have delusions that I might be able to sell these. 3D printing lets me build in concealment features in a way that kydex won't let you do without custom mold making, and I think I've got a way to go about it that'll be reasonably priced, comfortable, and mechanically performant.

>>64227425
what features anon ?
like what are you trying to achieve that kydex cant do ?

>>64227467
>Features
The shape is generally swoopy and soft, which generally helps reduce pressure on the skin, and that retention mechanism in green is what holds the gun where it belongs even though the shell isn't vacuumed tight to the gun. That bump on the back has a comfortable radius that's placed to max out how much your belt pulls the butt of the gun into you, and it works in tandem with the bump on the retention spring.

On the emotional side: fun colors and surface patterns built into the pants-side of the holster. These would not be quick-ship items unless a particular texture catches on.

Product roadmap for now is the non-light-bearing option you see, and a light-bearing option that retains on the ejection port. I'm not going to make a holster that doesn't accept a slide-mounted dot, and I'm probably not going to do prosthesis-level fitment as a service unless I sell enough holsters that I can quit my day job.

>like what are you trying to achieve that kydex cant do ?
On the product side, Kydex isn't great at making rigid elements for complicated retention mechanisms, but is otherwise a very good material for holsters. You could arguably do a swoopy outer shell in Kydex with a inserted retention mechanism to actually locate and hold the gun, but you might run afoul of Safariland's patent on the tech in the Bianchi Shenandoah.

However, on the process side, there's a lot about Kydex I don't like. Kydex requires molding, followed by secondary processing of the molded sheet. Molds take up space and are expensive to develop. Secondary processing kills you in manufacturing, which is why a really nice Kydex piece can cost you $100 or more. If I can get acceptable fidelity prints (working on it) in a material with reasonable strength and stiffness for the task (found a few), I think I can come in cheaper than that while providing a product of better quality than the Kydex you can get at my target price, at acceptable lead time.

Why limit yourself to 3D printing?

>>64226805
Been down that road before.
Keep a ramrod handy, highly likely you'll rip off the rims if you dont print the case and bullet slightly undersized.

>>64228307
do you walk into a liquor store and ask them "why do you limit yourselves to alcohol? why don't you sell cars or mattresses?"

Here is a project I've been working on: Chiappa RAK which I've re-barreled to .22 Magnum and designed a custom 3d printed magazine to work with it. I decided to make it into an AK74-esk build because I think they're neat.

>>64228792
Took a while to get the mag right, but it works pretty well. Needing to re-print an updated follower and the mag should be working well. Capacity is 10 rounds.

>>64228671
no problem with those in the picture, ive tried with 8mm mauser, they failed because i didnt print them thick enough at the bottom, the firing pin shattered the surface
i print them with a bit of over extrusion, almost all walls

only one that ripped the rim was 22lr, not enough plastic, which is why i stuck to inserts

>>64228792
>>64228808
this is fucking cool

>>64226788 (OP)
>>64226805
country? how the fuck do you have an MP-654k, that's a russian air gun
are you russian? if so, how the fuck do you have a PM? criminal connections?

>>64229174
Thanks anon. I made an attempt to get a bakelite finish on the mag. I think it came out alright. Still needs a little tweaking on the follower, but otherwise it's cycling pretty well

>>64229219
no, im yuro
mp654k are not quite common, but at least somewhat frequent, so I bought one
and I have a mak because I bought one
a nice soviet example, almost new

>>64229237
it does look good, i thought you made a magazine insert for a real bakelite mag

>>64229238
oh
these air guns are common here in Russia, I didn't think izhevsk plant exported to europa
so you have the gun legally? how do you make ammo? can you buy primers or just buy ammo?

>>64229251
oh you are the russian anon from the other 3dp thread ? пpивeт бpaтyxa

yes they were exported to yurop, the yunker ak are a bit more scarce than the mp654k

right now there is 2-3 on sale on a website
i have it legally (otherwise i would not dare to post it on this moldovan traditional stiching forum)
for now I just buy ammo for it
i need to make a press for reloading, get the dies and then I'll reload

i also want to try and make my own PIP ammo that only use a primer to lower cost
on a side note, I have picrel to shoot without buying co2 sparklets (refillable co2 sparklet on aliexpress), had to turn it down a bit on a lathe to allow it to fit
it is very welcome when the seals fails, as i can test for leaks without wasting a full co2 canister each time

>>64229304
>oh you are the russian anon from the other 3dp thread ? пpивeт бpaтyxa
are you the SMSLP Mk3 guy or someone else?
I'm the Russian guy struggling with primers, though I did some progress
there are two reliable priming compounds that can be had at home: the H-48 potassium chlorate one and the lead hypophosphite one
H-48 requires antimony trisulfide which I can't buy in a powder form (sadly)
and synthesizing antimony trisulfide at home from sulfur and antimony is impossible (well, you can make TRACE amounts of it. the resulting mix does not work in a primer, but explodes when smacked really really hard with a hammer)
because sulfur evaporates and you need a special chemistry machine to pass sulfur vapors through molten antimony in a vacuum so that sulfur does not combust. but they sell stibnite/antimonite, a naturally occuring form of antimony trisulfide that is the primary way of getting antimony trisulfide commercially. (no one makes it via sulfur + antimony since it's so hard and expensive)
I'm gonna try using stibnite to make the antimony trisulfide powder and report how it works in the compound
the second compound involves some wet chemistry and carries more dangers, you can get heavy metals poisoning from lead or lose some fingers if it explodes
overall I'm happy that I can buy ammo casings without a license
>i also want to try and make my own PIP ammo that only use a primer to lower cost
print in place 9x18? I am assuming it's a plastic casing? how would that even work?

>>64229321
>H-48 requires antimony trisulfide which I can't buy in a powder form (sadly)
the compound basically REQUIRES that antimony trisulfide is 99% pure and very finely ground, and what I got via my crappy stove setup had trace amounts of it with lots of antimony and sulfur that didn't react
and stibnite isn't pure either, it's like 30% sulfur but thankfully the H-48 compound requires sulfur, though not so much

>>64228690
I'm asking why you don't have more than one tool.
I'm not saying printing bad, I'm asking why only printing? You should make the thread about DIY firearms/accessories in general.

>>64229321
>>64229332
well, godspeed
i wouldnt touch any explosive chemistry, i like my fingers too much
are you sure you cant refine the primer from nails guns blanks ?
or we use to have caps guns with red plastic cups here, maybe those would work ?

for print in place ammo, look at picrel
you print round with a weak point around the bullet then stick a primer in the pocket
the bullet is propulsed by the primer, giving it a low velocity, but it cents to shoot for plinking (but you need access to primers)

>>64229343
>You should make the thread about DIY firearms/accessories in general.
I'm assuming it won't last long because (((malicious))) actors will try to sabotage it because it propagates psychohazardous knowledge for us europeans
the knowledge that you can make primer compounds at home is literally a psychohazard
it's illegal to share it in Russia
it is hence better too conceal it in a 3d printing thread

>>64229349
>i wouldnt touch any explosive chemistry, i like my fingers too much
it should be fine if you do it safely, though I didn't and got sick from sulfur oxide inhalation
>are you sure you cant refine the primer from nails guns blanks ?
the compound in those is a rimfire one, even though it should work in a centerfire cartridge it's practically impossible to extract and it only contains trace amounts
both of the homemade compounds will be more reliable and easier to reload because with only 100 grams of precursory chemicals you can make 3000+ primers
it is also financially feasible to make it from scratch because nailgun blanks, again, have trace amounts of it because it's a rimfire cartridge and the nailgun blanks available to me are made to misfire intentionally (people literally say it misfires even in a powder actuated nail gun, despite having an insanely hard hitting hammer designed to hit multiple rim points at the same time)
>or we use to have caps guns with red plastic cups here, maybe those would work ?
those are not reliable and don't have enough energy to ignite the powder

>>64229349
>for print in place ammo, look at picrel
so it's not a replacement for actual "combat" cartridges, if you put actual gunpowder there it will explode
sad

>>64229370
Dude, I'm not talking about chemistry, I mean like lathes, mills, grinders and whatnot.

>>64229321
nigga just use silver fulminate, it's a legal primary explosive that has the same impact sensitivity as regular primer compounds.

>>64229343
>>64229380
nigga, those cost more and are less accessible than a printer. I have two printer in my attic, but couldnt fit a lathe and a mill
go fuck yourself, 3d printing is a cool tech, which force designer to find novel solution. its the star trek replicator in real life, you get your own manufacturing unit at home

>>64229321
and, no, im not the SMSLP Mk3 guy. I dont usually post here, but i really like the diy/3d thread and was hoping some autistic cad anon would have a file for a makarov grip. Shooting season open soon, i'd like a better grip for my mak

>>64229370
no replacement for combat ammo, but combat i way far away from my consideration. I want to shoot cheap, often, fun. I do competition shooting, not insurgence preparation
But I think you can make "combat" grade ammo with blank in the same way, offsetting the rimfire primer for the centerfire primer to hit, you'd get more energy than with a simple primer (that wouldnt work for you tho with your shitty blanks)

also, in the ammo guide from ivan, they say you can dissolve it (i think, maybe in ethanol ? i know you can get spiritus here in russia), then even if you concentrate it much, converting 100 blanks into 20 rounds is still a win

god i hate this fucking timer

>>64229380
>Dude, I'm not talking about chemistry, I mean like lathes, mills, grinders and whatnot.
it's not as popular as 3d printing because it's harder, but it's welcome in this thread I assume
>>64229389
please, do tell, my brother in christ. are you a chemist? silver fulminate has never been used in primers
>The compound becomes progressively sensitive as it is aggregated, even in small amounts; the touch of a falling feather, the impact of a single water droplet, or a small static discharge are all capable of explosively detonating an unconfined pile of silver fulminate no larger than a dime and no heavier than a few milligrams. Aggregating larger quantities is impossible, due to the compound's tendency to self-detonate under its own weight.
and this is probably why.
>>64229404
>But I think you can make "combat" grade ammo with blank in the same way, offsetting the rimfire primer for the centerfire primer to hit, you'd get more energy than with a simple primer (that wouldnt work for you tho with your shitty blanks)
you mean drilling out the primer hole in the casing and pressing a nailgun blank there? been there, done that, it doesn't work, yeah
>also, in the ammo guide from ivan, they say you can dissolve it (i think, maybe in ethanol ? i know you can get spiritus here in russia), then even if you concentrate it much, converting 100 blanks into 20 rounds is still a win
the problem is that I can't get the compound out of the blank at all
I tried soviet 6.8x18mm and regular chinese 5.6x16mm

>>64229417
welp too bad. what solvent did you try ?

also, here is my collection of medkits (>>64229380 go make that with a lathe)

>>64229428
>welp too bad. what solvent did you try ?
none. are you talking about pouring a solvent into the nailgun blank to dissolve the priming compound in it after the NC gunpowder is out of it? I should try this too. I thought you meant dissolving it in something after you got it out, but it doesn't go out, it's like it's stuck in the rim

>>64229370
bruh silver fulminate is what bang snaps are filled with and it's not 100% pure precisely because it would explode on it's own. it's just paper soaked in silver fulminate.
you were looking for a widely available source of primary explosive, I gave you one, no need to be bitch and moan about it. it's still more viable than scraping the priming compound out of nail blanks.

>>64229431
yes that is what I mean
you can even recrystallize it for better purity, and you get a paste you are less likely to accidentally detonate by scrapping.
you can even use the solvated form to drop it in the primer and allow it to dry
did you look at the "but what about ammo ?" guide from Ivan ? i think they are doing exactly what you want

>>64229433
>bruh silver fulminate is what bang snaps are filled with and it's not 100% pure precisely because it would explode on it's own. it's just paper soaked in silver fulminate.
>you were looking for a widely available source of primary explosive, I gave you one, no need to be bitch and moan about it. it's still more viable than scraping the priming compound out of nail blanks.
you are assuming I can BUY silver fulminate? haha, I'd need to make it too
besides, I'm pretty sure it's not fit as a primer compound even if it's not pure, it's probably not as powerful and hence not reliable
>>64229436
I have V1.0 BWA, there's nothing there about using solvents to get priming compound out of it

>>64229446
>haha, I'd need to make it too
I just looked at it and it's probably as hard, if not harder to make as the other compounds plus it needs silver nitrate which is expensive
and it's harder to handle safely or make, so why would I or anyone use it? first primers (well, not primers but caps for caplocks) used mercury fulminate because it was more stable
if you want your ammo to randomly cook off then go on, use silver fulminate

>>64229404
>It's less accessible
You're putting arbitrary limitations on shit that makes everything worse like a fucking Boomer.
Having one tool doesn't make you better at that tool. It means you're more limited.
You can make a gun entirely from scratch using a drill and a file, but ain't nobody got time for that shit and it's not easily replicated.

>>64229446
i found that while searching around :
https://www.sciencemadness.org/talk/viewthread.php?tid=155595

>>64229466
have you make a working, reliable gun with a drill and a file ? if so, please post it.
in the meantime, i have a 3d printer, that I use to print stuff related to firearm (jigs, ammo holder, accessories mount, snap caps - actual guns are verbotten in my country, wont play with the dragon tail)
I even tried building a airgun with said drill and sandpaper (and files actually), it look like shit, works badly, but when introducing a printer, things turns nice.
also, if you have a nice project to show off using your lathe/mill/grinder/sandpaper, again, please post it, instead of moaning like a moron
go make stuff, stop bitching to people that do using tools you dislike

>>64229466
Go ahead, post your milled DIY firearm. I can assure you, no one here would complain if WA2000anon posted updates here.

>>64229477
I'll try dissolving the compound from casings that were rid of the gunpowder next weeked, but I think it's really more of a last resort, if the stibnite compound works then no need to do that because it's honestly better, you just mix antimony trisulfide and potassium chlorate, add trace amounts of sulfur, soda, and ground glass (more compound in less time!)

>>64229485
Manufacturing firearms requires a specific license in my country that I can't afford. The firearms I do own are professionally manufactured.
I am, however, a CAD/CAM technician.
I don't limit myself to only one manufacturing method. If the part is best made with a mill, it's made with a mill. If it's best made with a lathe, it's made with a lathe. If it's best made with wire EDM, that's how I fucking get it done.

It wouldn't even be a large investment for you to get into casting if you already have a 3D printer, but you're stuck thinking "OH IT'S JUST LIKE STAR TREK" to realize how to actually fucking use the technology as it currently is.

>>64229506
Post guns or fuck off.

>>64229506
man, we're not dunking on CNC tech
it's just more complex than 3d printing or primitive machining (angle grinder/arc welder combo used to make shitty guns)
the entry level is higher and if we're not using it it doesn't mean it's bad

>>64229515
3D printing *IS* CNC.
It's not an etch-a-sketch where you turn the dials to move the nozzle.

If you stop thinking of 3D prints as the END of the process, you get a LOT more out of it.

https://www.youtube.com/watch?v=8IBWICVNfz4

Zamak is what HiPoints are made of and can be cast at home very easily.

>>64229519
>Still not posting guns
Fuck off.

>>64229519
>3D printing *IS* CNC.
I meant CNC mills/lathes
>Zamak is what HiPoints are made of and can be cast at home very easily.
that's based but again, it's much harder than just 3d printing
I'm not saying it's bad
making a pistol with a 3d printed frame with a cast slide is cool, but you'd need a fire control group.. it's interesting though

>>64229527
>that's based but again, it's much harder than just 3d printing
Anon, you don't fucking get it, you can use your 3D prints to make the castings.

>>64229526
You fuck off.

>>64229532
>Anon, you don't fucking get it, you can use your 3D prints to make the castings.
I fucking get it
it's still metal casting

>>64229534
Zinc has a very low melting point.
The more ignorant you are about other manufacturing methods, the less capability you can get out of your 3D printer. You literally just need a filament swap.

lets ignoring the nogunz faggot derailling the thread, and get back to the subject at hand - 3d printed or otherwise, if lucky you have access to a machine shop - do you think a 7.62x39 silencer could work ? for more than 10 shot without becoming a hazard ? I sadly cant try it now, i had great success for 22lr
also, if any of you have the files (or the will to make it) for a PMm grip ? I can modify it alright when I got it, but i really dont have the skill to model a good one. Ive tried photogrammetry without success

>>64229541
I'm currently stuck at tech level 0 figuring out how to make conventional ammunition without a license
when I succeed at that I'm gonna worry about actually making a gun, it'll probably be a simple hand machined single shot 9mm single action pistol
>>64229543
>if lucky you have access to a machine shop - do you think a 7.62x39 silencer could work ?
no idea
>also, if any of you have the files (or the will to make it) for a PMm grip ?
there was a Russian odysee channel that had insane files on makarov barrels and such, I'm gonna post it here if I find it, I saved it somewhere

>>64229541
https://www.youtube.com/watch?v=0kxfDN4cKTk
also, just to please you massive faggot, here is a technique to casting metal easily without too much exotic equipment, but again, that implies that you have the space and the means to do it securely. I wont put my house on fire just to please a bitching faggot that dislike the title of the thread
now post guns or fuck off

>>64229543
You don't even need machine tools to make a silencer, just jbweld some washers into a tube. If you want more sophisticated geometry, 3d printing is probably the way to go, PC works well. Avoid very small feature sizes and just plan to reprint it every few hundred rounds.

>>64229543
>>64229555
https://odysee.com/@as.morgan:2?view=content
here
this guy a CAD file for a fucking makarov slide, it's insane
maybe you'll find grip files there

>>64229556
That dude literally does it on his fucking balcony.
Casting is not expensive. It's literally the cheapest fucking metal production method and you have a cheat for making the hardest part (the pattern) extremely easily.

You can literally make a forge with a coffee can, plaster and a propane torch.

>>64229558
i wish to have the sexy look of a PBS-1 silencer. I could print a housing for a tube like you describe, but I admit i'll go the long way and form proper baffles if thats the case. I even looks at buying a steel airshit suppressor and replace the internals with a formed baffle stack or a 3d printed core

>>64229555
How about a hypergolic primer? Firing pin strike tears the foil separating a chamber containing turpentine from one containing nitric acid.

>>64229559
thanks. He does have a PM model that I could dissect, but I'll have to work on it to get the PMm geometry I want
cheers anyway !

>>64229581
that actually may work but idk how to miniaturize it to fit in an ammo casing

>>64229602
Make a primer cup with a spike in the middle, fill it with turpentine, cover it with mylar foil and secure it with glue or a threaded ring, compress anhydrous nitric acid into a puck, set the puck on top of the primer cup prior to filling with powder, and after adding the powder gently pack the open space with wadding to keep things from shifting.

Disclaimer: this is all purely speculative and I'm not responsible for any fingers lost in the process of developing it.

>>64227425
That two-piece trigger guard flap thing looks like it's begging for an ND when something slips under it.

Having a consistent issue with both dmb and menendez mags. Both mags cause the slide to lock back on the last round instead of empty. Otherwise they run fine. Is this just a common problem with the follower geometry or am I doing something wrong?

>>64229640
Possibly, but the trigger will never be at the gap between it and the shell. I could ward it a little, but that will add bulk.

>>64229706
You could do that. Or you could just not have an unnecessarily complicated design with an obvious safety flaw.

>>64229763
>>64229640
I'm actually having a hard time making the striker drop with a foreign object that might get into the holster (paracord), short of wrapping the line around the bottom of the trigger and preloading it before I even put the gun in the holster, then pulling the cord after the gun is seated. That deliberate approach also works with normal kydex holster on both a Hellcat and a G26.

is jail time worth the 5 minutes of joy you get when you shoot an illegal single shot pistol?
it's so grim
>inb4 don't get caught
the risk is there

>>64230358
Good thing it's not illegal.

>but what about the Russian guy that can't even buy ammo?
It's not like following the law will keep you from being arrested in third world hellholes.

>>64230384
>Good thing it's not illegal.
it's illegal for me
>>but what about the Russian guy that can't even buy ammo?
this is literally ME
>It's not like following the law will keep you from being arrested in third world hellholes.
having an.. um.. ILLEGAL FUCKING gun certainly doesn't help it

>>64230391
Just keep a pack of cheetos on hand as an emergency bribe.

>>64231006
very funny
the problem is that doing illegal guns now out of all times is the worst time ever because of heightened anti-terror security
if I get caught with anything that can kill (that is, any gun. doesn't matter the technology, if it can kill or produces more than 3 joules it's regulated) they will think I'm some kind of terrorist and give me not 2 but 20 years in jail.
smoothbore black powder electrical ignition pistol? political assasination.
single shot 9mm pistol? intended to cover multiple targets with most ease.
FGC-9, Urutau, Rogue? clearly a mass shooter, why would you need more than 30 rounds (I can buy 32 rounder glock mags off local amazon for the FGC)
Luty? STEN pattern SMG? CLEARLY preparing for a GIANT massacre.
ALL I WANT IS TO SHOOT AT 2 INCH WOOD PLATES AND 2MM STEEL SHEETS INNAWOODS WITH 9MM LRNS.

>>64231024
Have you considered moving elsewhere?

how is this not a glowie thread

>>64231096
potentially I could. I'm studying for a major (education is free, yay!) that cannot be replaced by indians or AI, maybe only by high-ranking chinks. my dad also worked for an american company which I won't specify, he could have moved to US easily like twice, and all with a good job, but he decided against it because muh family and relatives. if I decide to immigrate to the US It'd take me like 7+ years (5 to finish education, 2 to work hard and recommend myself), and then 5 more potential years to get a green card (both in US and europe guns can only be had with a green card / citizenship)
I'm also considering getting a license (WOW!) which will allow me to buy a double barrel shotgun, then a pump action after two years, then a rifle after five years. and I'll be able to enjoy FACTORY GRADE ammunition. I'd need to appeal my psychiatric diagnosis: they consider you mentally ill (schizotypical disorder) if you think that gun control is bad and 2A is good (literally), I didn't pass the test because I talked too much, should have kept my mouth shut

>>64231105
american website. it's legal to manufacture your own guns in america.
80% lowers are not that much of a big deal if there's so many guns already
maybe european glowies browse this place but idk

Really like the gridfinity stuff for reloading equipment. Maybe some dedicated die holders would be nice:

>>64232652
Absolutely fantastic for tools…

>>64226805
I've been making converters I can use to shoot bbs with 209 primers, fun but I wish they'd eject better.

>>64229543
I think it's feasible to print one on a home desktop printer, even with the developmental restrictions in these early days it's possible to make pretty advanced cans at home on a printer.

>>64228792
very cool

>>64229633
Maybe something like sodium metal could work? The primer blasts open containment and sprays "grains" of sodium. And the primer itself acts like that hypergolic primer. You'd have moisture issues, especially with storage, but it can be made at home using menthol or just table salt and there are many video tutorials doing it in those ways. I know codys lab tried using it as a rocket fuel too, so if not for guns maybe for model rockets.

>>64235760
Why not both?

>>64235807
Genuinely, anon. It's because the ammo for this thing can hardly be printed. Or I've just been going along with it the wrong way. I have the STEP and STL files for a rough recreation of the mba gyrojet pistol, choosing the 50cal version for safety, and the ammo has been such an unbelievable pain in the ass to design and plot out its manufacturing. Truly, if I could afford gyrojet ammo I could print this rocket gun and be firing ye olde gyrojets from a nearly 100% plastic pistol that'd melt in my hand from the blast. I want it so bad anon. I even managed to recreate a 50 cal slug that I planned to hollow out and use as a projectile rocket. But I just don't think it can be done. Pic rel is the recreation of the main housing that I made back in 2021.

>>64235858
Dope. I can see how the ammo would not work out printed, but could you drill out the jets and primer pocket from a cut piece of bolt and thread it into a pipe? Slow but doable vs stamped brass shells.

>>64235922
I absolutely could. But here's the way I figure.

I wanted to lost PLA cast the shells in one piece, then do the same for the engine to make a two piece mini rocket with no payload ability so I'm within legal bounds. Then I could make the rounds out of aluminum. I had tried several different fuels including regular gasoline, JET-A-, steam, pure hydrogen and oxygen gas produced from hydrogen peroxide reacting with aluminum after drain cleaner strips its oxygenated layer, pure hydrogen peroxide and now pure sodium mixing with water. That cycle of trying different fuels and wanting to stay away from gunpowder keeps making me change the nozzle design, size of the rocket, etc.
As well as if the rocket round itself is a gyrojet at all and has multiple nozzles to make it spin, or if I can make it a much MUCH more simple design that has fins. Or more recently, a drag tail to make it stable in flight. I did manage to blow up pic-rel with literally all of those fuels but the sodium and the JETA though. The aluminum casted ones were often too heavy to fly right thank's to me being inept with casting.
I'm open to new ideas though. I think I've thought myself into a corner with this one.

Bros I am thrilled, I've not used one before but I know they're fast. Any tips?

Didn't actaully answer your question.
I could do that but 12.7mm when it comes to homemade rockets that have any kind of power and use the fuels I want to use are so small. It infuriates me how little room I really have for the low thrust but easily made fuels I have to work with since I eliminated gun powder, black powder and hobby SRB's. Sodium's really my only hope at this point since it fits my narrow New Vegas inspired criteria.

Why would you not use the only fuels that have a chance of working?

Ah, yeah I totally glossed over propellant. Come to think of it even using double base nitrocellulose the originals didn't have as much force as they were hoping for.

It's more fun this way. Otherwise I'd have been done with this three years ago. But I think a gyrojet can be made so much better if it has ammo and fuel you could feasibly make in your homestead or, post nuclear world. Using FNV Goodsprings as a basis for that. It's been a lot of fun going through all the different designs and propellants and it might be something useful in the end too.

Which poster who said they limit themselves to 3d printing are you replying to?

>>64237218
the one he made up in his head, so he could bitch about it not being a thread about everything else
next his noguns ass is gonna hop into an AR thread asking "Why limit yourself to AR-15's?"

>>64237218
Why is the thread 3dpg instead of diy or homebuild, then?

>>64237319
i like how you ignored the post above you, on account of the fact it calls you out perfectly
take your sub 20iq the fuck out of here, you knuckle dragging heeb

Print at 50% speed, hot and slow is how you get the strongest prints.
