Edit: To summerize, it is a design depicting how to move a single barrel arround multiple firing chambers to get the effect of having a gatling gun without having more than one barrel, thus it being field legal.

Meh, Not a bad Idea, but I would personally go with something similar but simpler. Very intriguing design, but too complicated. I would use a revolver style mechanism. Don't get me wrong, It is a great design for design's sake. But it is complex for practicallities sake. Though I don't see where the hopper goes.

My 2 cents.

You have made an interesting design. But it is not a Gatling gun. A Gatling is a multi barreled gun. You have designed a mag fed gun similar in setup to a Thompson sub machine gun.

I hate to be the person that says this, but why not just get an electro?

the coolest paintball "machine gun" I have seen was an A-5 with an e-trigger and a body kit to make it look like a browning .50 cal from WWII. Honestly I don't see why you wouldn't just stick with something like that.

You've basically designed a gun that is heinously impractical, incredibly overcomplicated and would have trouble keeping up with any modern electro.

I do not think this is the case. As specified in the designs, the yellow areas are the firing chambers. (maybe that of a tippmann or an SP1 even all the way up to multiple Dye NT's) and as the design calls for multiple firing chambers, you may attatch multiple hoppers to the marker/s [sic], thus increasing feed speed. The barrel would not be going from chamber to chamber slowly mind you, however the faster the barrel moves the less inherently accurate my marker designs would be.

I don't think there's anything on my designs to suggest the use of a magazine, although using multiple q-loaders (Helical magazines technically) would make sense.

I still do not know the gear ratios for the oscilating design and I have not come up with a good way to attach a paintbarrel to a bicycle chain as of yet. so yes it needs a lot of work. I had suggested the use of a drill as a power mechanism, and this would allow the end user to alter the rate of fire as they see fit. anything I suppose from 0 to 60bps for the chain design (signifying 2 very high end markers fed by rotors) and 300bps for the oscilating design (assuming 10 high end markers/firing chambers, all fed by rotors) You would need relatively stiff and lightweight barrels for both designs, and obviously the shorter the better. the end user would have to be careful of snapping the barrel in half (or buying a better barrel) in both designs.

I would like to see what a few of the Mod's think. They seem to have a more keen eye for engineering possibilities.

^^^I'm not a mod, but I'm a double major in mechanical engineering and engineering science... does that count?

First off, I definitely like the creativity behind this design. Is it the kind of mechanism that is likely to replace electros as the high-ROF weapon of choice? Not likely. However, that shouldn't necessarily stop you from trying to build it! If you have the resources and patience to pull it off, you'd certainly have one of the most unique markers in existence.

To do the theoretical work behind this you'd need to understand epicyclic (also known as planetary) gear trains. I don't think I could explain the analytical methods over the forum, plus I don't know what kind of mathematical and/or engineering background you have. If you want to look into it further, I learned about these systems from this textbook. Some of the topics in this book require previous experience with statics, dynamics, and kinematics - but the sections on gear trains are relatively straightforward (as far as math goes) if I remember right.

Also, you can probably find something smaller to use besides bike chain. I'm sure you could find smaller chain and/or timing belts from lots of online stores. Here, for example.

All I can ask is......what is the purpose? What are you going for with this design?

^^^If I may interject my interpretation...
The purpose is to build something that resembles a gatling gun, but that will still be "legal" on fields that have a one-barrel rule. Whether he wants a gatling gun because he thinks it'll shoot faster or because it's just cool I don't know...


Also, I had an idea since my last post - to get the intermittent motion of the barrel, you might want to consider a geneva mechanism. These are covered in that same textbook that I recommended. I'm not as familiar with the math involved in designing one, but it would allow you to get a very specific rate of rotation of the barrel and have it come to a complete stop every certain number of degrees.

You'd probably want more and smaller increments between steps than this one, but here's an example of how a geneva mechanism works:

Haha you know don't you :D

Fair enough, it may well be despite what I say ^^

Generaly BFG stands for "Big F'ing Gun"

In response to I.K.E., I am trying for a gatling gun style mechanism where one barrel moves arround all the different firing chambers so as to make the gatling gun (as pertains to paintball) lighter weight, and have less moving parts.

Silent-7, Thank you for the advice on the "geneva device" I will use it when i get my computor fixed and am able to update my schematics. (all my schematics are on the one computor.) I do like the geneva device. it is much simpler than my original thoughts, and i believe it would make my belt driven design fairly obsolete due to less reliability, more maintenance, etc. thanks.

No problem!
And I agree with your assessment about the reliability factor and such.

Also, if you ever want to bounce any other ideas off of someone, don't hesistate to talk to me. I absolutely love working with stuff like this!
