I'll take a stab at it, I can't see the purpose of the fixed stock, I think a thinner folding stock would work better and probably weight less. I just can't see how the fixed stock is helpful in any way of being ergonomic or useful.

looks good, what software?

A telescopic and/or folding stock would be the next project. This is mostly a trial to see how sturdy it can be.

The main issue I have with it is the location of the threaded hole for the stock. I've recessed it into the thumbhole, but I'm wary it'll still be noticeable.

>>31058701

It's an AR-7. I just haven't modeled the barrel assembly yet.

Also, I should note that I've added a hole through the back of it so you could still loosen the screw for the rear sight to adjust elevation if necessary (threaded hole, rear sight panel and screw not yet modeled).

If the sights aren't intended to be used, I might raise the cheek weld a bit, use that threaded hole to also attach the stock (increasing rigidity) and just using the rail to mount some sort of optic.

I made this and 3d printed it. It's a "hammerhead" style knuckle duster. I saw it online and thought it looked cool so I copied it. This is 3 revisions later after printing several variants at once and continuing with the best of the batch.

conclusion: too small for a decent grip. Ineffective toys marketed to EDC nerds. It goes in the same pile as "edc tops".

>>31058760

>>31058778
sure.

The 10mm and 15mm thickness felt best. The cutouts are slightly oval to fit the fingers better than circular.

Gonna try and model a PS90 style forend for the fs2000 as soon as I get some free time.

>>31058828

Cool.

I wonder if it would work better if it extended far enough that you could apple pressure to the side with your thumb.

>>31058866
Yeah I think that would help. When I hit stuff with it it slips toward my thumb. Some texturing wouldn't hurt either

>>31058828
do you have one of those 3D copiers that use reflecting light create a 3D computer image?

if so, you should make your design out of clay then squeeze it in your fist so it will fit better. Then 3D copy and print.

>>31058931
Nope. My friend tried building one but it's not working, I think the microcontroller he ordered is dead

can I see the trigger and barrel-swivel mechanism plox?

>>31059119

Current trigger is a placeholder so that I could estimate how far to put the thumbhole.

The barrel threads on the front. There's a little slot for an alignment pin on the top.

It's a really simple firearm. I always wondered why they were so inexpensive and now I can see why.

Not overfond of the trigger mechanism, to be honest. It would be much nicer if the trigger and hammer were a separate unite you could just drop in, rather than pieces you have to sortof align together while they are only supported on one side and then squeeze the side plate on trying to line up the holes.

Things to consider for changes in future versions.

>>31059660
is it long enough for your doggo to survive?

>>31059673

I'm basing the model off a stock AR-7. This one came with a 16" barrel.

That said, I could make the barrel 9" shorter and it would still be legal in my country.

>>31059689
Damm, what is the name of that paradise you live in?

>>31059703

Canada.

Our laws are, overall, worse than those in the US, but there are a few saving graces.

Our laws are confusing, but they are the same across the entire country (minus Quebec because reasons).

For rimfire rifles, there is no magazine capacity limit and the barrel length isn't really important (>106mm for a rifle? CAN DO!) as long as the overall length (folded/collapsed if applicable) is 26" or greater.

>>31061550
Ive established im probably going to be using a PSP Construction system with a 30% margin ontop of the suggested best safety standard.

Still working on a hatch idea without doing a dedicated form around the top entry hatch. I have a couple drawings and spec sheets on my own but Im most likely going to rework them because I wont be able to source any materials from timber at the site.

>>31060886

Wait, which application is that?

>>31061687
it is autocad of last year...

>>31061719

Ugh. I had hope that it was at least Inventor.

AutoCAD is way better than hand-drafting, but I fucking hate working with it since using parametric software.

>>31061736
>parametric software
what? i only know how to use it not how it does.

currently designing a multi-cal bolt face for a striker-fired, tilting-block action . should handle case sizes between 5.56 and 308win. ideally, it will be able to cycle rimmed stuff like .454casull and .500sw. currently the action length adjustability is limited to about 15 cm by compressing the secondary recoil spring, which i dont like too much.

second part is figuring out a universal-type magwell that is initially patterned after an sks internal, but pops out to take others like that stanag adapter for galils and vz58's. i want it to take stanag, ak, and AICS magazines, and the internal mag can change calibers with the follower

>>31061768

Let's say you make a 4x4x1" plate with one corner at the origin and you put a 1/8" hole 1/2" away from each corner.

Then, later on, you need to either make a revision or a modified version of it that is 6x6x1" with 1/4" holes 1/2" away from each corner.

In AutoCAD, which uses "dumb solids", you'd have to manually do that shit.

In parametric software (Inventor, SolidWorks, etc), you set relationships between features and geometry.

So, if you set it so that the holes are 1/2" from the corners, it doesn't matter what you change the overall dimensions to, because the holes will just move to the right position. You can set it so all the holes always have an equal value (so you only need to change one), etc.

When you get into stuff like bending sheet metal, any kind of simulations... Hell, even just making the 2D drawings for the guys in the shop is a fuckton faster. Fuck viewports. Fuck having to generate a 2D drawing in the 3D area just because AutoCAD is too fucking dumb to make an actual section view using the section command in paperspace for a model that has any referenced components...

I seriously fucking hate AutoCAD and just thinking about how roundabout, slow and wasteful it is makes me mad.

I'm thinking about building a gas piston rifle that uses a trip lug bolt. So basically a leader T2.

>>31061861
that sounds interesting. admittedly the model i screencapped has a few known mistakes (receiver blank was too short for reading the wrong measure). the interface to inventor seems confusing, i tried it once a few years ago but didn't really like it. i may have to try it again, i know autocad has come a long way since that time i chose it.

>>31061861

torrent.
pirate bay is good. stay away for torrents with only 1 seeder and no leechers, people will stay at the good ones.

>>31062016

The first day you start learning parametric software, it's a lot to take in.

Basically, you have to change the entire way you think about creating the part. The "best practices" are very different from using dumb solids.

It absolutely is worth learning, though.

>>31062031

Just torrent it, bruh.

>>31062099
>>31062190
what about licensing keys, does it have a grace period or something? is there a specific edition to look out for?
last time I used CAD that wasnt blender was autodesk in like 2010
I know there are legal issues with selling stuff made with pirated software, but ill pay the 5k or whatever for it down the line

>>31062288

Whichever pirated version you get should have instructions on how to get around the keys.

But yeah. If I ever plan on producing anything commercially, it'll be with a legit copy.

>>31062288
usually when you pirate it, it has a keygen enclosed with it in the .iso as well as instructions (some of them are not always 100per cent accurate but close enough that a nigger could figure it out if he needed to).
modern versions require you disable your connection to the internet during activation to circumvent cloud verification. worst case you may need to look up the product key but that isn't too hard to find, i think autodesk even lists them on their site.

>>31061090
>64 character password with Cyrillic and unicode
For what fucking reason would anyone have this much security for a design over 125 years old?

>>31062288

Oh, I should add: Make sure the version you get is NOT a student version.

Student versions put big watermarks on all drawings.

If you take something that isn't student version and so much as sneeze on it with a student version, it'll apply the watermarks.

So any work you did on the pirated version wouldn't be worth shit even if you purchased the software. At which point you'd have to remake it all from scratch.

>>31061807
You'd be better off simply making different clip on mag wells in my opinion.

>>31062410
Couldn't someone with a lot of time, calipers and a Mosin just do that? What was special about these prints?

Also were the events related or just a coincidence?

>>31062385

That'd be at least a ~55 kilometer shot at a dog I don't have.

>>31062427

Reverse-engineering is hard. I'm not even going to pretend that my model is going to be 100% accurate to the original.

A lot of information, like the engineering fits, would be on the drawings but not visible on the end product.

>>31062484
Oh, I don't into engineering so I didn't know. Though you'd think with all the Remington contracts you would be able to find some English blueprints and info.

Project:
FN-125 (model year 2025)

Made largely of composites and carbon fiber, most of the weight is in the barrel assembly. This is an integrated combat weapon chambered in 6.5mm.

The barrel is a combination of several layers of - hardened steel and nanocarbon sheet which has become ubiquitous at this point. Overall weight of the entire weapon is 3.8 Kilos though when fully loaded the weight may surpass 5kgs. Soldiers are not expected to have the grenade launcher loaded until necessary.

It feeds ammunition from 2 horizontal magazines mounted at a 50-70 degree angle as shown on either side. Quad stack capacity of 50 rounds each (originally 60).

A disconnector trips when one magazine is emptied, flipping to the other one for nearly continuous operation. The other magazine can be replaced without compromising the weapon's ability to fire.

Introduced first on the P-90X in the early 2020s the "infinite magazine system" caught on quickly.

On the bottom you notice the 25mm Grenade Launcher, with a 6 round magazine capacity. This doubles as a heavy gauge shotgun for door breaching and close combat.

Like the dated OICW it can deliver timed airburst grenades, if the operator chooses. The launcher is semi-automatic.

The grenades are slightly lower pressure than original 25mm spec though provide a decent range boost over the venerable 40mm system with a muzzle velocity of 125m/s.

Having learned from the tactics of the russians, thermobaric point-detonating warheads are also available and when combined with rapid semi automatic fire can at least equal the firepower of a larger weapon in urban indoors combat.

>>31062427
they are production prints for 91-30 containing original dimensions to other pieces and possibly some that haven't been revealed yet as nobody who has acquired them has posted them on the internet (i assume there will some with higher quality than ones for the 1891 variant i have found). I know they are there though because he did post previews of them where I found them and somebody on a different site hinted at what the password could possibly be. I assume he changed it because the person was not wrong then, i tried it but it didn''t work for me, but there were others who had thanked them for sharing the code.

using calipers is difficult, i have calipers and a mosin. not an undertaking i would like to spend time for when the numbers could be right in my palm without seeing. also having the information is nice so it will not be lost. eventually somebody nice may be able to make new parts or somebody could get help for a project.

thats almost exactly what I'm going for, actually. if you check out Colt's 901 series of 308ARs, they just use a simple piece of metal to mate an ar15 upper and space out the magwell for STANAGs. my idea is to have a similar drop in magwells for detachable mags, and the integrated fixed mag pops out like an sks, and is immediately interchangeable with AICS patterns. having an external release for the magwell is too much of a operation hazard and introduces more moving parts

>>31062701
>machinists
most machinists are cool and understand that you can't really defend designs that a single person could come up with in a day or two

it's just gun nerds who are so rabid about MUH CLOSED SOURCE (even though it's not "source") and have to "reverse engineer" everything in overcomplicated ways because they can't come up with any new ideas.

>>31063245

He seems to have a hate-on for Americans for some reason, since he keeps throwing it at everyone in the hope that he'll be right for once.

Even on /k/, one of the most America-centric parts of the website, he can't even get it right.

>damage control
I'm not even the same person you argued with before, just thought I'd throw my 2c in. Didn't think you'd make such a big deal about it, but whatever.

>>31063234
ok sorry
i didn't want to be mean or w/e
i just didn't understand

>>31063303

The only damage control to be seen in this thread is from you, though. Just look at the backpedaling from the Resident Evil comment.

Even the guys who mistook the gun for a pistol at the beginning of the thread had the good sense to either shut up or leave the thread after finding out it's a well known gun designed almost 60 years ago.

I'm starting two projects I might work in tandem, one is whoring up a 10/22 with some Legend of Zelda imagery and stuff for a later project. The other is modifying a 870 adapter for ar-15 stocks and grips so that it fits on my Mini-14's wooden stock, so I can have some modern'ish A-Team action going on.

>>31063341

He has been asked the same question multiple times. It really pays off to read the thread, man.

Sounds good, man.

Gold highlights would be great for the LoZ one.

This guy's right, lets stop discussing doing things and go back to arguing theoreticals. That way we can act better than other people based on our opinions and not our abilities.

That's a good idea, I'll look into how to and where on the gun to do it.

So was the step in earlier models deemed unnecessary?

Just bought a CETME kit. Gonna see how bad i fucked up when it gets here. Im terrified im getting in over my head but also at the same time excited for my first build.

Exit bag. See y'all later.

Im stealing this to make before you. Thanks!

Just at the theory stage at this point but I've been brainstorming about how to convert an AK to fire 9x39 in case project Yedinorog never comes to fruition

It's just a different kind of suppressor. Two stage versus a monocore.
Mine is also pretty light since it's aluminum.

>>31065386
9x39 from what brass? Also, what bullets?

>>31066354
From the same brass things like 358 Gremlin are made from. Bullets are also fairly widely available.

>>31066370
So youre converting it to 358 gremlin?
Afaik .357/9mm sptzer bullets are pretty uncommon

>>31066414
It's possible to form your own brass from other calibers. This is all the gremlin guys did, same witht he .35x39 from the 70s
Actuall 9.3mm spitzers are quite common.

>>31066455
I cant check right now but I know .35 remington is longer than 39mm
Spitzer 9.3 is indeed a "common' big game cal, I may have taken you too literally at 9x39.
imo, I think the biggest you wanna go would be 338 bullet in a cut down 308 case, allows for a decent ogive in the bullet and higher case pressure, while still fitting the 'intermediate' size. 9mm class is limited to the soviet step type tips or the Whelen round nose

Design for a simple pen gun .22lr taken from a blueprint patent from 1926

I'm going to weld a broken v spring for a shotgun tomorrow with some music wire and a wall outlet.

from what I understand I'll need to preheat to kill the temper, weld it up and then temper again.

If it works that would be great and I'll post it here but I'll be surprised, if it doesn't I suppose I'll have to make a new one out of one of those flat crowbars. So either way I'll be learning how to temper a spring.

Trying to model a bullpup stock to turn my stockless m1 carbine into a short pdw

What software do you use?

>>31069142
I would either use Inventor or Creo
if it has to bee free, use FreeCad
http://www.freecadweb.org/

>>31069187
Thanks! Are there any premade M1 carbine models I could use for scale?

>>31069196
just look through the web

I usally go to grabcad or 3dcadbrowser
http://www.3dcadbrowser.com/download.aspx?3dmodel=28245

>>31069213
Thanks for the tip. Now if I can just learn how to use this thing

Good morning. Glad to see my thread hasn't died yet.

>>31069142

As previously stated, I use SolidWorks 2013 right now.

>>31069187
not op, but how do you use freecad I use sketchup and i'm sick of it

OP here.

>>31070349

Freecad is shit, too.

Get solidworks or inventor.

>>31070449
Ok, Let me rephrase, How do you use solidworks or inventor?

>>31070546

All parametric software functions basically the same way.

Make a sketch. The lines/arcs start off as undefined. As you add dimensions or relations (like parallelism, perpendicularity, concentricity, tangency, symmetry, etc), the software will actually "know" where the line is. It will be "defined".

In Solidworks, if your model has any blue lines in any of the sketches, you're not done yet.

I know it's tempting to put the corner of a part at the origin if you're used to dumb solids, but you're better off putting the center there most of the time, as you can use the front/top/right planes for a lot of functions.

>>31070610

Also, I should add that it's a best practice to use "mid plane" for extrusions as much as possible.

The advantages of parametric software will make even more sense once you get to assemblies.

>>31058737
why not just 2 captive crosspins from opposite sides? On the top and bottom of the pistol grip? Or just in the top if you are set on making the pistol grip integral to the stock.

>>31070676

It's made to fit on a standard AR-7 receiver. I can't change the location or angle of the threaded hole.

>>31070695
But you can put a small piece that is attached to the receiver by a bolt in that threaded hole.

And then attach the stock to that.

That mounting piece can be a pistol grip or a smaller wrap around piece that extends rearwards enough for 2-3 crosspins holes either side by side, up and down, or a triangle.

This piece could be aluminium and then attached to this you can make some nice polymer stocks.

>>31070969
This is true. Could have it take some sort of standard stocks/grips.

Again is this what gun laws are about one AR pistol bottom

op what country is this

>>31071230
But anon please don't ruin

Hey so >>31067234, here. So I got it to strike an arc but it keeps sticking and vibrating until I force it free, I've been using rake tines and some scrap steel as a practice material but am getting no where with it.

Any welders mind helping out?

>>31071349
stop what the fuck you're doing right now and spend like 50 bucks on a harbor freight welder or something. fucking christ this is probably a troll but what the fuck is wrong with you.

>>31071230
I have no idea what you're asking.

>>31071349

Amature welde here first off

>>31071438
>>31071862

Are right, you are going to die if you keep fucking around with this shit but when you do get a welder pay attention to the settings provided, you are right about the tempering but completely wrong about the way of getting there. Also buy good sticks, a bit expensive but you weld with the idea that the part breaks before the weld.

I'd like to build an air rifle but I'm depressed and poor

i figured I could make a spring piston easily out of a sturdy bike pump by replacing the pump's head with something a little more robust and adding a spring, and using the rod you actually grab to pump to catch whatever trigger assembly. but like I said, I don't even have 3$ for a dollar store pump to try it with and even if I did i wouldnt give enough of a shit to bother

>>31071959
You can build some cool stuff from salvaged material. Got any good recycling centres nearby?

>>31058699
Unless that stock has a recessed magazine holder or allow survival stuff to be contained in it.
Better yet, a massive magazine is made inside of it. :}
