What about the 35 round drums? I know they weren't the greatest but they are certainly less unwieldy than a chain dangling down from the front.

Seeing as rifled barrels are becoming more common place on darts, I'm assuming similar tactics have been tried on the balls. What has been tried? From personal experience I know that, when fired fast enough from a barrel, golf balls will be unstable in flight unless you use a rifled barrel. Hell even a little back spin makes them much more stable at higher velocities.

 

I've wondered if sprockets are the best way, or if a proper pawl setup would be better and NERF et. al. doesn't do it because they're used to turrets and turrets work fine for stock blasters.

 

Either way, I was thinking 1" 200 PSI PVC would be a good shell size. 3 darts should fit no problem, 4 if you cram them in, mega/rivals could also fit if you wanted. OD is 1.315" for all varieties of 1" PVC, ID is +/- 1.16-1.189". PVC because it'd be cheap enough to build a belt out of: 10' of the stuff would make ~40 links in the chain for ~$5 (plus whatever filler you use to make the barrels). When I was considering it more seriously, I was going to make a jig to just duct tape the shells together into a belt. Seemed like a good combination of simple, reliable, and cheap.

Oh wow, I misunderstood what you were asking for. For some reason I got in my head that you wanted to chain feed a doomsayer. So what you are asking for is a chain fed shotgun in the literal sense. That's a bit different than what I had in my head. Let me think for a bit on that.

 

Again, rifling isn't really what matters here. Check out Slug's recent thread about the VF1 barrel alongside the SCAR. Both were identical unless the fit wasn't right in the SCAR, then performance was better on the SCAR. The whole idea of fishing line is an adjustable elastic barrel, not to impart spin. People like JSPB and others who do it for spin are correlating two things and assuming causation. In terms of fluid dyanmics, it makes no sense that spin would help a nerf dart, DOOM wrote a dissertation-style nerf document that modeled a dart and came to the same conclusion, and cited evidence that spin doesn't help. DOOM'd document is an excellent read if you're up for it, its on his website, go read it.

 

What Meaker is getting at is there is zero advantage to turning/milling a rifled barrel for nerf. Either 3D print Slug's VF1 and tune the diameter, or use a SCAR barrel. 

 

 

I hope that you are either being flippant or are referring to the dimensions of some specific part, like a nerf dart or stock vulcan chain. The dimensions are dictated by the design that no one has come up with. Everyone and their little sister can CAD these days, that part is trivial. Spending the time to design, prototype, and revise is what they were asking of you, not simply drawing up someone else's work.

I'm not talking about using it for a dart. From the evidence slug has presented its obvious that this would not work on a dart. I'm talking about the rival rounds and making them more stable at a higher velocity. I only want to use a mill because I want to. I like to work with my hands, that's it.

 

Woah you have an engineering degree that obviously means you are a god of design and fabrication and make literally anything

I neither have a degree nor am I the god of fabrication. What I do have is a fairly well equipped machine shop and some advanced research equipment. I also have a little bit of fab experience with stuff like automotive intake manifolds, exhaust, and chassis bracing.

Woah woah woah engineer. Current SCAR methodology is just fishing line run through the pipe and anchored at either end. Try that first, then break out your fancy mill.

Fancy mill? Its just a vertical mill. Wouldn't be hard to put some barrel material in an indexing collet and start drilling some holes. I don't typically use the fancy cnc mill. Also, I always hated those fishing line and nail-on-a-stick methods for getting a rifled barrel.

 

A chain fed shotgun would be relatively easy in theory. Just replace the turret with a couple big sprockets like the vulcan has. Get me some dimensions and I can make a solidworks file simply enough. 

That's adorable.

 

To be clear, rifled barrels when used on darts are not used to impart spin. Anyone who claims that spin is the what makes the dart more accurate has a pretty elementary understanding of what's going on. I'm sure you already knew this though, being an engineering undergrad and all. The only reason that it's useful to change the twist ratio (a la Scar) is that doing so also changes the elastic inner diameter of the muzzle device. As you might imagine, more turns = smaller effective diameter.

 

Rifling and hop-up would be much more beneficial on a projectile with uniform density, like a rival round. As you nay surmise with your spud gun experience, hop up can increase the range and rifling the accuracy. I have seen some work with hop-up, but haven't seen much with rifling. That would be an interesting place to start if you're looking for a project.

Yeah I know, I tend to brag too much when I've been drinking.

 

I can think of a few ways to put some rifling inside a barrel. What is the current preferred barrel material for the rival rounds? Initial idea would be to mill a sleeve of tight barrel material and then slide it inside an outer barrel. Trying to make it out of one piece and be uniform would require a much more complex machining operation which I really don't feel like dealing with.

I like the idea of a chain fed absolver but it doesn't really make a lot of sense with the all the high cap mags available now. I was talking to my brother and apparently whats keeping the power down on the ball shooters is the plunger size. Is this correct? I could solve that real quick on the lathe.

 

#humblebrag

Yeah bud. Want me to tell you all the ways I better than you?

can i just say that your construction skills suck and to stop making homemades

can i just say that your construction skills suck and to stop making homemades

You joined in August '07 just to say that?

Yes but from what I've seen from his "guardian" he is building bombs.

I'm in the process of doing this. I started it when I saw your post in the mod/pictures thread. I need some kind of substitute for the SDR PVC because they don't sell it up here. Any advice? This thing looks Effeminate. Great job.

It is also known as for thinwall or sch. 20 PVC.

Could you show us some pictures of your godly blow..... gun.

Wow I love it. My only greivance is that the pump and barrel are still visible. Not that you could do anything about it.

Why did you have to copy my gun and take credit for it?

The pump and blast is just a water gun. I have already seen it in target.

I'm with Talio my parents no the cost of gas so they find different ways of getting to work. My mom carpools and my dad rides his bike. Which is why he decided to build an awsome new road bike.

What kind of pressures do you plan on using in this gun anyway. 40? 50?

You are such a panzy. Do you know how hard it is to break sch. 40 pvc? The only way you could break a pressurized vessel would be to swing it as hard as you could against a tree or something like it. It wont do anything if you just drop it on the ground or bump it.

Oh great another memeber lost his memory. The first time this happened was with that boom31 guy.

Here is the original pullback shotty as promised:


And here is the the real reason I invented it and a sneak preview of whats to come

can you whack it in with a powerful enough blow?

that kind of blow is not something you'd intentionally give out to a blaster..

Aj

To sig or not to sig...

I dig that paintjob, but no more 2k's?
A splitfire? Very mysterious.

What do you mean mysterious? What does everyone do with a splitfire? Its not that hard if you think about it.

Dang it. I was just about to make mine.

It doesn't look that way to me at all. Maybe you can supply more examples?

The +bow is pullback because it's an intentional homage to the crossbow.
The Ultimator, XXL Bazooka, Maximizer, MaxShot, and perhaps even the stronger versions of the PistolSplat are more powerful than a Crossbow. Certainly the ERTL Pump Shotgun, and possibly its Rapid-Fire sibling. None of those are pullback. What other powerful blasters are?

I see your point Bob. All these blasters, except the shotguns, provide quite a bit of leverage to compress or extend a godly spring. Perhaps you could come up with a lever system for the PAS to compress three +bow springs.

I believe it is easier to use a pull back than pump action, because the muscles in your arm have more leverage your arm is at a 90 degree angle than out stretched.

I'm really not into this because im not a body builder and that doesn't look to pleasent to pull back

Well neither am I but it is easier to prime. Why do you think the most powerful nerf guns ,like the crossbow and plus bow, are pullback.

I will post pictures of the original once I finish painting it(sometime today).

Get ready for the shotty guru.

Military Simulation. All the veterans and old farts hate it, thats why you have been getting all the warnings. They believe that nerf should be nothing like airsoft or paintball, so I would suggest that you take off the digi camo and put on some shorts and a t-shirt.

On topic: I really like your ideas to put different aspects to the game. I every war I have been in it it was standoff after stand off of long range primaries. Its nice to see someone working on something that needs improving and not useless +bow variations.

I agree, it would definitely be useful to add point values for rscb/hopper/inline clips, since they're used so often nowadays.

Wouldn't that just fall into the the "clip" category?

I really like this idea of putting blasters into specific classes but I do see 2 problems with the system.

1. Not all people may have a specific blaster for each class. This would be especially a problem where I nerf as many of us don't even have a proper pistol.

2. You're rate of fire measuring system doesn't take into account air vs. springer. I personally am working on a clip fed shotgun ,but the pumping would make the actual rate of fire slower than most singled springers.

Again, I am not bashing the idea but suggesting a couple refinements that would help to convince others to use the system.

Does anyone else notice how it looks like a spartan laser?

This is just all kinds of awesome. I can't wait to see this unfold!

Holy crap! The Great Stefan returns.
(my apologies to Baghead for going off topic)

For every one wondering about the new darts, they are 1in diameter with hard plastic as the tip.

Hey guys, I was thinking about hosting a war up here in Atlanta, and I was wondering what date y'all would want it to be on.
Any date except July 10-17th would work I think.

Our group down here have no chance of going to your war. Sorry but please don't hijack this thread.

I have two pairs of saftey glasses, a bigblast pump-handle, and a Tech Target blaster that fires mega darts. If you want something that you left tell me. I cannot do the whole shipping thing so I'll just have to find someone who can, if you cannot wait till next SENO.

The big blast pump handle would be mine but you can just throw it away. Also what do the safety glasses look like.

Man I cannot wait till next SENO you can expect me and aside to bring 2 people each so thats 6 people for the away team next time.

It was an awsome war, I am definetly coming to summer SENO.

Pros:
+Good weather
+Seeing the amazingly clean SNAPbows
+Being able to fix my big blast
+Watching my little brother nail Zaxbys then chase after Rork

Cons:
+Aside breaking my big blast
+Not being able to buy an at2k

We have some people in the neiborhood we nerf in who are constantly making fun of us. Last time they were yelling crap like FAGGOTS!! or GET A LIFE!! while riding in there golf cart. But these paintballing rednecks were paying to much attention to us and started to veer into the other lane where they were nearly hit by a pickup.

Will you people quit complaining about running. It is getting pretty annoying. Also you can count on my brother being there the whole day next time and hopefully with a better gun. You shall all know the foamy wrath of the indestructable child.

I am going to have have to say the 30th on this one.

Any ideas for adding more cover to the fields? All thats out there is light poles.

Seriously people how could we let this thread drift to the bottom of the second page. Considering our last war we should have near 10 pages of BS buy now.

Also the home crew could have 1 more nerfer.

My bad, I didn't think it was worth making a new thread over. I can edit it out if you want.

Its fine I already quoted you so it doesn't matter.

Uhh time to revive this thread.


VIVA LA SOUTH SENO

Yeah.

It's also Spanish for "breast"

So dont go searching up images on google(unless you really want to).
