#92596 Nerf Shotgun
Posted by SHADOW HUNTER ALPHA on 22 October 2006 - 01:50 PM in Homemades
When I say "Shotgun," I'm referring to the way the weapon loads shells into a magazine below the barrel and how the pump cycles the weapon. The design is similar to Boltsniper's SCAR-N.
One more thing, I'm a noob. Deal with it.
Edit: There is an update on this project at the bottom of page 20.
#92830 Nerf Shotgun
Posted by SHADOW HUNTER ALPHA on 24 October 2006 - 02:25 PM in Homemades
First, the term "shotgun" in my title only reffers to how the weapon loads. If I wanted to fire multiple shots, I would need a sabot or something, and that's really not a design I can get into right now. To load the shells, I was going to use a carrier in front of the magazine. For those of you who have shotguns, this idea will probably be familiar. If not, then visit this website (http://science.howst...om/shotgun5.htm). Towards the bottom of the page, there will be a box titled "pump-action shotguns." If you play all the way through that, and study both the tab on loading and the tab on firing and ejecting, then my concept will be broken down for you.
Next, my ammunition problems. Since I am planning to use shells for this weapon, I am trying to borrow the design that boltsniper used for his SCAR-N. Those shells and stefan darts should give me some good ammo. To keep the shell and dart from sliding out of the barrel, I will use a rotating-bolt lockup unit like the ones found in shotguns, assault rifles, and the SCAR-N. this will provide the basis for me to both hold and extract the shell. The weapon can be cycled by connecting an operating rod to the pump grip and the other end to the bolt. If you look at the bolt concept of the SCAR-N, you can see the nail sticking through the side. That should be what I connect the rod to.
I want to make a practical, compact, yet sturdy design so my gun doesn't fall apart if I slam-fire or am rough with the pump. The silencer is for quiet shots if the weapon has a decent-enough range for "sn1per" operations. I would be grateful if I even got 20' on the first attempt, seeing as this is my first homemade. I promise you guys out there that as soon as I get my scanner working, I'll put up one of my rough sketches on here for you to all see what I'm talking about. If you have any ideas or alterations after visiting the HowStuffWorks page, then I'm all for your suggestions. I'll need them to make sure my idea holds water before I go off and build a failure.

#92863 Homemade Shotgun Question
Posted by SHADOW HUNTER ALPHA on 24 October 2006 - 05:13 PM in Homemades
Keep in mind that if you use shells, you will have to get a bolt system and extractor, instead of just a plunger. If you want to keep this design simple, then just don't use shells.
P.S.: If you ignore this and make shells anyway, then make sure they are small and light, like brass. Do not use anything bulky, like PVC or anything that is too hard and time-consuming to replace if you get them lost.

You'll also want to check that the dart can't slide out of the barrel. If the barrel is removeable, then take it out and put a dart in the end the bolt connects. If the dart slides out without any force, then it is too small. If it gets caught on the way in, it's too big. The only reason I put these basics up here is that I overlook stupid shit in my work all the time.

P.S.: If you have no idea what the hell I'm talking about, go to howstuffworks.com and search for "how shotguns work". Look for the page about the loading system and use the interactive feature designed on Macromedia Flash Player to go to the slide on the carrier. You'll see the carrier dog, the piece that I intend to move.

This is the hand-drawn version of my design. It shows a rough plan of what I intend to do. If you read my last post, you'll understand what the depression tab is and where it is here. Anyway, now that you have an idea of what I'm doing, I hope you understand what I will be talking about. This image should help to clear up some of the confusion.

Posted by SHADOW HUNTER ALPHA on 26 October 2006 - 08:04 PM in Homemades
P.S.: Forgot to mention that I don't need a spring for the bolt if the pump will be cnonnected directly to it. Also, those 2 things on the front of the weapon are a silencer and an LED flashlight for CQB operations. (Close quarters battle)

Posted by SHADOW HUNTER ALPHA on 26 October 2006 - 09:08 PM in Homemades
However, getting back to the idea of a mag-fed pump-action, your idea for reducing excess room near the bolt is something I've been thinking about. If you know how a shotgun works, then you know how the carrier works. The depression tab in my design has to be built so that the tab won't come down until the shell is already loaded in the breech. If you come up with anything, let me know.

Nice drawing. But how big will the gun really be?
Will multiple darts fit in each shell?
The gun will, ideally, be no bigger than Boltsniper's SCAR-N. If I incorporate the plunger tube into the stock, then I could theoretically shorten the gun by around 20cm, and also eliminate some durability problems with an attached stock rather than an integrated stock. That little stub you see sticking out of the left part of the drawing was going to be an attached stock, but I scrapped the idea and forgot to erase the part from my sketch.
The gun will have shells, but I don't plan to have multiple projectiles per shot. It will be a slug-gun type weapon, like I said earlier. In order to fire off multiple shots, I would need to involve sabots or something of the like, and that would only be as a proof of concept attempt. Multiple pellets wouldn't go very far anyway, so it would almost be pointless for wars that aren't fought in buildings.

So, yes, I am making the halo 2 shotgun. - LastManAlive
That Halo 2 shotgun concept seems like it might fit my plan right down to the sights. If you come across any advantages or problems in the design, PM me or post them here.

Sounds like someone has done his homework. I agree that both of our concepts have some flaws, and there's no getting around that. My carrier and bolt designs are going to be pains in the ass to build, since I haven't seen anyone do this kind of thing before. Your gravity feed is also going to have a lot of problems with jamming in an intense firefight. However, I think that a lot of the problems in our systems can be worked out through trial and error if we both contriibute to each other's designs. It would also help to see some other readers contribute ideas based on their experience as well. Hopefully, some of my parts will be compatible with parts or upgrades you may be developing after or during your project.

Posted by SHADOW HUNTER ALPHA on 29 October 2006 - 09:14 AM in Homemades
It sounds like the shotgun you want to build will be a break-open breech type weapon. If that is indeed what you are doing, then you probably do not need or want a pump. Shotguns and other weapons that use pumps have a solid frame, where the cycling rod can be directly attached to both the pump and the bolt. Break-open shotguns are only connected at one point: the hinge. this means that there will be no way to effectively attach a pump while still having it [the pump] serve a useful purpose. Since my design has a rigid frame, a pump would be the most beneficial. For breech-loaders, you can either manually cock the weapon with a charging handle, or you can find some way to make the two hinged halves of the gun cock the weapon as they fold back together.
My own gun will probably have some tight fits with the carrier, but that should be the only real problem. As far as I know, I'm the first one here to ever use a carrier, so it looks like I might have to pioneer some fabrication techniques. However, when I get the gun finished, it should definitely be something to look forward to.

You're right, though. That thing does look really fun to shoot. Just don't aim at anything made of glass or anything that wants to continue living.

I looked over your post again and realized that I mixed up the word "travel" with "gravitate" because there is a typo there. However, there is still a problem with your design. The size of your dart and the size of the breech can be perfectly identical, but if the edge of another dart even gets caught between the rim of the breech and the loading system, you are going to have some major problems with the firing because now there is a bent-up dart that prevents the breech from closing and getting a good seal. That either means that you can't fire, or the pressure that is lost while firing is too little to propel the dart out of the barrel.
Also, I don't know whether you are going to make a true breech-loader or a magazine-fed shotgun, because they are definitely not the same things. PM me a picture and I might be able to understand and help you.

All of the major parts have been labeled so there's no confusion. The depression tab is indicated, and the vertical line connecting it to the bolt is the spring. In the carrier spring base, the U-shaped gray thing is the carrier spring, fully compressed. I'm sorry that there's little defenition between the carrier and the bottom of the magazine, but the carrier ends where the bolt and barrel meet. That should give you a general idea.

To address the problem of shells slipping out under the carrier, I plan to make a small spring-loaded tab that will be able to fold in towards the magazine to load a shell, but not out when the shells try to fly out from under the carrier. Also, the space for the carrier to hold the shells will be limited to exactly 1 shell and no fractions above or under that. To stop the shells from loading themselves onto the carrier and preventing the carrier from being pushed up to load more shells into the magazine, I might have to design some type of catch on the mag. tube that you flip and it blocks off the shells. I will probably try something else, though, because that seems like it might take way too long to load this thing if I use that idea. (I'd have to flip the catch up and down for every shell I load.)
If you have any other problems or solutions, then tell me.

If you used a height-adjustable base like I described, then your idea would be perfect for all different lengths of stefans or stock darts. However, if you are using / making the same size darts that are in Forsaken Angel's pics, then the ammo case would be much easier, simpler, and cheaper. Your idea is probably best if you need to manufacture / store multiple sizes that won't all fit in an ammo holder.

I'll definitely try to get some bigger pics up sometime in the next 2-3 days.
Now, about that depression tab issue. I thought about exactly the same problem you did, that the depression tab would come down too soon and the carrier would go down before the bolt could load the next shell. But then, I remembered that I'm using a rotating bolt. This means that if I shorten the tab just a little bit and place it at a point on the bolt where it will be timed to release only after the shell has been loaded, then the problem should be solved. Then again, this is all just speculation, since I haven't made a model or gotten into all of the mechanics just yet. If I post a way bigger detail view up here, then I might be able to talk to you guys about the really fine details of it all. I only wish that boltsniper could post something here, since he's actually built a rotating bolt before and he could give me some insight as to what I might need to do here.

1: If the carrier and carrier dog are connected like that, then how does the entire system move when the carrier is raised? I know the carrier dog moves, but it seems like it would have to move towards the carrier to raise it, based on your picture.
2: Where am I going to find a set of gears that small and how am I going to keep them in place should the gun be dropped?
3: How would I solve the problem of a jam (I.e. a locked gear) without dismantling the entire receiver?
Even though I don't know the answers to these questions, I will probably switch over to the carrier dog system instead of my depression tab. That way I have a proven system and don't have to worry about springs or very strenuous pressures on the sides of the bolt and carrier. I'm not discounting Flaming Hilt's arguments, but I might be able to pull this one off more easily than the depression tab. I guess this means I'll need to draw more pics, but still, thank God for Ronster.

Seeing as you can't fillet weld, I guess you'll probably just have to keep trying to pull the pipes apart.
P.S.: What did you use to glue the pipes together, and how much of it. This could be affecting what choices you have to fix this problem.

I forgot that the carrier dog does indeed move towards the magazine. Noob mistake #654 - overlooking simplistics. As for the axles, I was thinking some thin music wire or a really skinny nail, something that won't bend or crack easily. I intend to clean and lubricate this gun well, so your 3rd suggestion won't be a problem. As for the gears, I think it would be easier to find some at a hobby store or something, since I'm not paying $3 for a single gear. (and I have yet to see a round, gear-like Lego.)
With these problems mostly solved, I need some suggestions on how to prevent the shells in the magazine from slipping out of the gap when the carrier is raised to load a shell. I have a feeling that my spring-loaded tab on the end of the carrier might not work since it will be too big.

I still don't get that slide - breech thing. Maybe you should draw a sketch like Ronster or give me a web page with an example. I do better with visuals.
#93470 Nerf Shotgun
Posted by SHADOW HUNTER ALPHA on 01 November 2006 - 06:00 PM in Homemades
I've never seen Star Wars, so I can safely say it was an idea that I worked on as I went along.
Ronster:
Those Lego gears actually might work. I have to give some thought to finding the right type, but it looks like something in that picture will work. I'm not discounting Meaker VI's suggestion, but I just think it would be easier to have a system that I've seen be proven reliable.
Meaker VI:
I acually need all the help I can get figuring out how to make a removeable receiver, so if you had any ideas, post them.
Flaming Hilt:
You may need to explain your drawing a bit. I see that the pump pushes a peg of some kind back, but that's it.
#93548 Nerf Shotgun
Posted by SHADOW HUNTER ALPHA on 02 November 2006 - 06:44 PM in Homemades
Maybe this would be easier if you drew a diagram that shows the pump, peg, etc. in relation to the parts it affects and the parts around it. (Like I did for the carrier.) I understand that the pump pushes the breech door shut, but where is this all in relation to the surrounding parts?
Ronster:
How the hell am I going to repay you for your help and opinions on this topic? First, you explain the carrier system, and now you're building a model? Where do you get this kind of free time?
#93599 Nerf Shotgun
Posted by SHADOW HUNTER ALPHA on 03 November 2006 - 05:36 PM in Homemades
Ronster:
Of course I'll give you credit. Everyone who helps me here will be given due credit. I don't believe in taking help without an honest announcement about it, so if there's a favor I might be able to do in return (I.e., some high-quality stefans once this gun is done), just name it.
