I'm not a new member of these forums nor do i give my two cents about many things nerf, I know how to keep my mouth shut unlike so many noobs out there. Sure I use the guns for my wars at University but other than that I simply love to build weapons.

With this, I liked Bolt's FAR which I'm not alone in the love for that damn thing.

With all the ideas about Magazines they either involve shells or simply darts, where there really isn't anything to stop it from jamming or what-not and that I can't get past that unreliability.

So why not a revolver? But not really a revolver....



I'm building a homemade right now and this is what I based my mag design on, it's basically a revolver/chain magazine. It is easier to seal than a regular cylindrical revolver and has many other qualities that make it far superior to a typical nerf magazine. My design has 24 shots in basically a 10x3.5x2 inch box and I'll post pics when the whole gun is finished.

It's a good thing you don't post often; that attitude could get you some hefty flames.

Apart from that, the idea sounds like an interesting one. I'd like to know how the chain cycles inside the magazine case.

Don't give him shit, what he said is absolutely right with all the useless posts out there.

I like the looks of this idea, the only thing is it looks like it might look a little awkward sticking out of a gun like that. It seems a little bit bulky I guess I'm trying to say. I don't know, if this works maybe I will try to make one with half the shots or something to cut down on size. Well good luck with your project.

I dont understand how the mechanics of the magazine work...is there some sort of spring somewhere that pushes the rounds in the firing position?

Other than that, I see no reason why this wouldn't work...although it would be rather bulky, like leftnut said.

Hey, I dont give two cents what he give two cents about, but I am interested in his project and am eagerly anticipating it's outcome.

Wrath, Enigma,

The magazine is basically a conveyer belt in a box. Inside the box there are two sections of 1 1/2 inch aluminum pipe that has niacha 6002 industrial bearings inside to make them move freely. The chain is a laminate of ducktape and hockey tape just because hot glue doesn't stick to my brand of duct tape well. I was going to epoxy every one of the 24 pieces of pipe onto the chain but I doubt it would be worth the time, if the glue isn't strong enough I'll make the switch; but it worked on my prototype chain so it should work great.

K, imagine a rototrack and imagine that its chain is actually duct tape and pipe and its ends are attached and spinning around two points. Might make it easier to see.

I have some concepts for the actuation and as of right now I have the idea of a section of bicycle cable nested in 1/4 inch copper flex pipe attached to the bottom of the trigger of the paintball gun and a spring loaded armature which will swing down and catch on the pipe and as the trigger is brought back to its original position the next round will be advanced into firing position via spring. I'm building as I go so this is the next hurdle on my list.

I'm a little worried about pressures and am looking into a 'rock' regulator, if anybody knows anything about paintball guns it would be greatly appreciated to learn if under 100 psi-200 psi if anything will have to be replaced inside the gun, like springs and such. Obviously I'm not planning on an 800 psi nerf gun. I do have an idea to try about making rubberized bullets, like a plasti-dip jacketed candle-wax bullet, who knows it might work as a heavy alternative but would probably hurt like a mofo.

I can post updates if anybody is interested, I dont know how to set up a web-blog or anything on par with renegades FAR in progress. I could figure something out, but I'm an arts major so bear with me.


Ps. i did act like a jackass when i first posted awhile back, which is basically why I never post, but I learned my lesson.

Do the rounds (forgive the term) just sit in front of the barrel, or is there something to push them into a coupler or something? If they just sit there, you're going to lose a lot of air from leakage, decreasing your range.

[WratH]

Most(if not all) paintball guns don't run at 800 psi. I've heard of people upgrading so much to get under 200 psi with just regular paintballs. I think. Don't take my word for it, I don't have a guage on my marker so I don't know what pressure I am running at.

[FromAbove]

About air leakage, I've been worried about this and around the shells as they rotate around attached to the chain they basically follow guides made of acrylic that are exoxied in place. There will be some air escaping around the shell, square hole and round block sort of deal.

Keep in mind I've spend some time grinding down the ends of the shells so they sit as flush as possible against the end pieces where the input/output holes are and the guides will be as close as I can get. I'm still in the whole development/tinkering with ideas but when you look at a revolver there are gasses escaping from the tiny space between the revolver and barrel. Oh and I found out that when lowering the PSI of a marker, you use more volume of gas to power the marker. The magazine will be sealed as best as I can as well can be said of the magazine well. This will of course only leave the input and output holes to do anything about the pressure and I'm hoping that the increases in gas volume per less PSI will make the whole thing work, But i bet if I tinker with a lower volume of gas per shot I'll still be fine, look at foam weights compared to a paintball and 21 inch barrels on a marker arent uncommon.

Tonight I moved away from attaching the shells directly to the chain...metal pipe doesn't want to stay stuck to tape of any sort. Instead I built up some hot glue and made 'fingers' that passively move the shells around, this means I need to rework the actuation or make the fingers more solid with exopy because I need solid movement around a flexible belt, Its been rewarding working all the designs out. Its such slow progress so if this whole thing actually works, because money really isn't an option I think I might spoil myself when I'm done and give the gun either a fibreglass or kevlar body, maybe carbon fibre? 300 dollar nerf gun anyone? something strong and light because I really dont want to be lugging a 30 pound nerf gun( /whatever fits into 1/2 inch pipe) all day.

Sounds great! You seem to know a great deal about what your doing and am really looking forward to what the product will turn out like.

Just to clarify things though. Does the magazine "hook" into a handle like a standard pistol?

What form of propulsion are you looking at ie. co2/plunger/pumped air. If you use pumped air may i suggest a (sorry cant find the name or a picture anymoere) small bike pump. They pump about 120psi and are only 30cm.

Are you going to make this a semi-auto or single shot. (i know you have a mag but havnt heard about your propulsion).

Sorry to ask all these questions but i really would love to make a belt fed system and has been a must for me to try now for a while. I was thinking about using dics but your idea seems so much more practical, so when your done would you think about putting your plans up like bolt did for his F.A.R (and hopefully pistol)?

Skiz,

The mag is going to feed into a 'typical' square magazine well. It's going to be held in place by this weird little contraption I came across at "The Depot" and it is a spring loaded roller, which is only about an inch long and this is going to be used as the magazine catch. So to remove the mag all you need to do is exert a stong downward force.

I'm looking at c02 because It's being built around a paintball gun, which I already have a coiled remote for...I'll build a harness for the bottle too but first things first.

Being a semi-auto paintball gun the gun itself will also be. I'm designing it to advance one shell per trigger pull...hence semi-auto.

To be completely honest as of right now I have been forced into redesign after redesign over the belt feeding. I will get it done but it is forsure much more simple to make a typical top feed mag, no matter how daunting it seems. It's a swift pain in the ass but I want something original, I wont be one to rest on the laurels of Boltsniper. But with that, keep in mind they are quite nice laurels, (insert generic kiss-ass comment admiting bolt's amazing homemades).

Tomorrow I may grab my roommates camera and snap some pics of what I have going so far, I'll post some if they're worth seeing.
