Gatling gun

a couple thousand rotations could be over in a few minutes. Personally, I'd have one port that mates with each barrel in succession, that seals through a tight fit between rotating disks. Add some thick motor oil, and you have a pretty good seal(but you need probably at least two machined parts) You could also extend the back plate to seal with the OD of the rotating barrel assembly. That way, you only need 1 valve ( or none) with one (somewhat leaky) seal.

This seems simpler than running electrical connections to 6 valves with one air line.

I guess you could have the whole thing, including the air tank rotate and tell it to go with a single IR LED and phototransistor.

Everyone is discussing how to build it
I think that instead we could focus on whether it makes sense

sorry I do not see any reason for this other than esthetics

ramses' idea is practical, but again it's for looks nothing more

Theoretically, it could be practical. If every barrel had the feed port in a different place, each loading mechanism could feed 1/6 as much, which should help with jams/misfeeds/doublefeeds. Of course, if the thing was spinning at 600 RPM, the jam would just crush the BB (and maybe damage the gun). If this was combustion/hybrid, it would be much more practical; the chambers would stay cooler, and the steps of ignition could be physically separated.

But yeah, most Gatling guns around here have the real barrel in the middle fed by a BBMG.

for rotation you could use ir sensors hooked up electronically to a air tank some way so only one shot is fired when the barrel gets lined up with the exhaust port get what im saying?

yeah but you will also need delay timers n stuff coz valves take time to open it might only me a few ms but in that time the barrel would have moved on

Well now that it's 2012, chances are you don't really need anymore input, but during my aimless wanderings on spudfiles, I saw this and couldn't resist commenting...

I've actually thought up a similar design before and faced the same swivel issue. why not make the entire gun swivel? In my plans (which I have never, and most likely will never build) I have a very large central tank at high pressure (probably a scuba tank.... my grandfather was a scuba diver so he has some extras) and it's placed inbetween six barrels, all with two valve - one opening into a smaller air tank that powers each individual shot, and one that actually fires those tanks. all solenoids. pricey, i know.

Sorry if this doesn't help. Being 4 years late probably isn't helpful
