Just when I think im "custom" or "cool" or "special" you show me up and put me in my place.
That is a beautiful build!
Awesome
so nice
Very cool. Love the concept. Have you test fired it yet?
:hail:sa weet!!!!!!!!!!:hail:
Dear Goatboy,
How much? Can you make me one? Do you own the 3D printer? Can you make one that's got a powerfeed but can switch to the rotary magazine? Also congratulations that is awesome/beautiful and a great contribution to the platform and community.
Friz
bah, just a six shooter. if i am with a hopper, i can get 200. how bout dem apples? :stick:
but its still neato and groovy.
Shut up and take my money!
What is even more impressive is that given the state of your entertainment center, you developed this back in the mid to late 90s :)
OP delivers! Very cool.
El Zilcho: lol :p
You are doing it wrong. ;)
That's very slick. Nice work.
I also like that you are consistant in your admiration for the old school. SS autmag body, CRT tv, and is that a PSONE?
How did I know you guys would notice my 90's era backdrop? FYI when I was a kid, I didn't even have a Playstation -- that's a Super Nintendo.
Haven't formally test fired it yet; will try to do it this weekend. Inspection and manual cycling with chopstick seems to indicate it will work just fine though.
Uh, well, I wasn't planning on letting this out of the bag but yes, you could just merge the rotary loader housing with the BT Picatinny adapter and have a DAM-like dual feed system. It would require additional work on the mag2cocker adapter and possibly the body to allow the breech to freely rotate and semi-lock, but I think it would work. Not sure if it's something I feel like undertaking at this time.
Speaking of -- this is pretty much just a prototype, and as such it was kind of expensive. My prototypes just have the bad habit of actually working. The rotary FS loader alone, with it's 3d printed parts and a few metal bits, cost about $100 in parts (I'm sure that can be easily brought down but again, this was a prototype). It doesn't work alone though -- needs a warp notched rail to lock into that still supports the classic pim style (hence why I went ahead and 3d printed one of those), barrel or adapter cut for FS rounds, and a classic body also cut for FS rounds.
So... I'm not much interested in selling these. I don't own a 3d printer (or any relevant machinery or even a decent shop) -- all these parts were drawn up in OpenSCAD and produced by Shapeways. Mechanicals aren't even my area anyways, much less actual manufacturing... I'm sure there are much more capable people in these forums for both of those tasks.

This is awesome. Excellent job. I bet, you could probably design a q-loader-like-pod to do this as long as the "track" is the right shape.
Wow! :wow:
If this was done I'm the guy you want to contact. I could see if HQ likes em, if so the might make a quick run, if the do well with little to no problems and a good deal of interest then we modify it a bit, then we might have them produced to a certain extent, maybe a little something for goat boy and I would be given as a reward :D
Well, the way I see it, it definitely would not be compatible with the q-loader system. I just mean a similar spiral loader concept.
Add a slide setup to that and you could have it and a hopper. Just slide forward or back for what you plan to fire. Now that is sweet.
And goat. My living room TV looks lime that. Your not alone.
cool idea!!! need to make one with a huge drum....like a tommy gun.....hmm I might make myself one
I have a really, really good idea brewing. Goat boy, could you give me the dimensions of these? I have a pretty good idea that has a very, very slim chance of working but I could talk to you and the company about it.
My first attempt was actually to re-use the end drive section of a q-pod out of laziness. It was close, but there were just too many little things wrong with the geometry for any of those parts to work reliably. It did convince me it was a viable mechanism; just wound up being easier to redraw everything and integrate the housing + body cowl in one step anyways. That and the paddle is a bit delicate for my tastes.
Also, I figured out how to make the FS/normal paint selector. Minor changes to parts, but involves some metalwork.
Freedy500: Uh, what? 6 chambers, 0.700" bore diameter... It's actually extremely similar to the q-pod's drive section, but with thicker paddles (0.08" wall thickness). The rest of the parameters are mostly calculated from these numbers.
How was working with shapeways?
Shapeways is the only place I've used so far so I can't offer a comparison against the competitors.
Dealing with them is generally positive; the people answering their emails seem to be pretty responsive. The best part of this process is actually the fact that I *don't* have to talk to anyone. Upload design, pay with credit card, get parts.
The parts can be hit or miss (another reason I don't want to get into the selling of these). I got some parts back after Shapeways had been hit by Sandy and had to move production, and those were all quite bad (still getting their machines recalibrated I assume). If something is not printed properly they offer a refund or something, but I've so far been able to buff most parts into shape.
Subsequent parts came back much, much better. Turnaround time is a little better than it used to be as well; 'bout a week.
The three main parts for this loader all had minor out-of-spec'ness in some areas, but I managed to buff or work around all of them. There are certain geometries that are still difficult for their tech.
Last I checked, their online system doesn't have any sort of revision control built in, so that exercise is completely up to you currently.
So overall I've been pleased.
Test fired today:
http://www.youtube.com/watch?v=JWzO9abzlF0
Hah, max embedded videos per post is 1?
I need to find a better dump pouch as the current one is not good for rummaging around in.
So the thing is mostly complete.
I want a new back cover because the one from Shapeways came out somewhat deformed; a clear acrylic piece should be fine, and more importantly, actually be flat.
Need a new front cover because with enough pre-winds the spring will want to shoot out the front. I can have about 12 feet of prewinds because... the spring is actually harvested from a tape measure. So I should be able to pre-wind it like at the beginning of the day practically and not worry about winding in the field. Just load paint as I go.
And maybe I'll cobble something up to make the mount a little more secure.
But so far everything works as designed.
Oh, and the number of shots is technically a full six, however if I take that 6th shot without reloading then the 7th round goes slack, and is in danger of going in sideways (although the L10 bolt is excellent at catching it). So it's 5 shots with a 6th safety shot in the chamber.
Most of the time I'm single or double shotting people with regular paint, so I think this will suit my play style fine and defeat anyone trying to count shots against me.
awesome
keep us posted
This is great. I know you mentioned above you're not too interested in selling them yourself, but I'd love to see you run with the idea and somehow bring it to market. I'd buy one. Please do keep us posted
have you seen any possibility of a bigger drum? more like a tommy gun size?
ill see if I can get our printer up and up again.
Neat concept but as is seems pretty impractical. Reloading time seems to be really high. Have you considered more of a "mag" concept?
I say worry about the practicality later. This is a proof of concept, and a pretty awesome one. I'm sure Goatboy already has a more efficient loading system in mind.
For some reason I would like to see this load like a cap gun. Pump players carry dozens of 10 round tubes. Maybe this could have a 6 round preloaded ring that the player could carry a whole bunch of?
Just musing.
The design was sort of parameterized for # of chambers and bore diameter, with a few "that looks about right"isms thrown in. (Hence why I don’t have outright measurements.) I originally actually started with 5 chambers. So yeah, I could pop one out with x number of chambers, with x possibly being over 9000.
There are lots of variations of how to feed the paint (including a speed-loader like device from the back, a front-loader like on the DRV or that Krotary rifle, and even possibly a q-pod-like device), but in light of my current manufacturing level (level zero), and play style, I decided to stick with a simple, implementable design and just defer to manual dexterity. My reload time currently is dominated by rummaging around in an improperly sized dump pouch for the task. This is a fixable problem. I’m making one of those carriers like I saw on MCB, which I think will work great.
The capacity is a tradeoff against being able to continuously top up combined with low profile. I can literally reload while posted on someone, where I typically have all the time in the world to top up, and this gun I can top up one-handed. I can even top it up while moving.
Magazines are fine and all, but the problem is they require 2 hands to reload once you’ve run them dry. I haven’t seen a magazine based setup where you can reload with one hand. If you try to bring enough mags to not have to worry about it, chances are I will make it to the 50 before you do.
The closest to this is the DAM with a double-mag clip. You can change mags, and then an empty mag is available for reload right in front of you, allowing you to possibly reload, one handed, while posted on your opponents. It’s still not ideal though, and mid-mag changes on paintball guns are currently still a mess. And the DAM is too bulky for front player use. And it’s Not an Automag.
I actually played with the thing today. It took me 2 games to get used to it, but after that I found my rhythm. No problems except for me firing that 6th shot in the first game and getting the 7th shot in the chamber sideways, which I had to fix while in the snake.
http://1.bp.blogspot.com/-nAcyWY9F00...40/nutshot.jpg
Yeah I saw that too. No followup on whether or not it actually works or if it's ever been mated to a gun. Problem still exists -- when you pull the follower back to load it, the stack loses pressure, and you'll only get 1 shot, and the next will either be empty or a round will fall into the breech sideways. I know someone who made a straight FS magazine, and apparently it suffers this problem.
So here's one of the games from today. Just a casual rec game. No misfeeds or anything of the sort; most of my reload time is me fumbling with 10rd tubes and pouch and not the actual reload, and a few times I reload while posted. I did get like a 100+ft single headshot through a small side window of the pill box/deer blind at 1:00 though.

That is so awesome!
Any chance of open sourcing the files so others can print their own if you don't plan on making a run?
Hi, I’m GoatBoy, and I’m addicted to FS rounds.

Ran around with FS rounds today. Also tested out some equipment; the FS pez dispensers were still a little tight so I need to loosen them up.
Also managed to break the ends off my impeller paddle, which looks like this:
https://images1.sw-cdn.net/model/pic...1377841863.jpg
I had been playing with a broken one without realizing so I was like… well, what happens when I break the rest of them off?
Well, the thing actually still feeds perfectly fine, but goes into free-spin (that’s what causes them to break in the first place) after the 5th shot instead of the 6th shot.
This was not surprising; I figured it was going to happen since the same problem exists with the q-loader impellers, except the plastic they use is even stronger than the photopolymer I used for this one. It’s really a pretty minor deal and there are a number of possible solutions.
Easiest solution is to make one out of metal (or just back it in metal or CF) and be done with it, but I’m batting .125 in getting metal parts made, so I’m going to beef it up a tad and give the nylon a try next.
I’ve also given some thought to releasing the design. What I’ve decided is that I’m waiting on an external trigger event (which I’m not going to divulge). If that trigger happens, I’ll release the source and you guys can take over the thing and do whatever you want.
why not use an impeller from a Tippmann Cyclone kit? those are while 2 tiered can be found in metal.
or in a soft pliable version
Oh geez why didn't I think of that.
I'll take a look at the part; I suspect it won't work because of different dimensions and different required part right in the middle, but that's a damn good idea.
Ehh, nope, those paddles are 5-shot and not 6, and they're not the right dimension.
Making 'em out of hard rubber would be fantastic though...
In light of that, maybe I'll 3D print a mold instead of the part itself and mold my own rubber parts...
youre welcome:D
