I've begun construction. Sourced a motor and cut the barrel disks and found the barrels. Barrel disks are made of 4mm perspex. Going well so far, I'll get some pictures up soon.

I wouldn't really reccomend poly (I think it's only for water/flow perhaps?). ABS and pvc should work fine, I haven't really had much experience with metals holding that much pressure. Waiting for an experienced pneumatic guy to post would be a good idea. PVC becomes brittle at lower temperatures so...

It wont be as fast as a sprinkler valve, but if it's a higher speed mg then the performance should be above satisfactory. If you don't mind risking it you could try modifying the speed of the servo, as most servo's geared for rc cars have a lot of torque. Good luck

It was better than my first ever attempt at a spudgun.. Nice job!

So if I use an agitator through the bb's, which will then exit the barrel when in the correct position hopefully, will it actually fire or will the barrel not be in place long enough to release the bb's?

When I was thinking about reloading mechanisms and the vortex I realised that unless I got a very fast motor the vortex would have a better rof anyway. How much does it hurt a vortex's performance to not have a constant airflow through the barrel, only for a short time? Would it even work consistent...

I'm designing a micro gatling gun. I'll use a cellphone (vibrator) motor to rotate the barrels (8 barrels, about 3.5mm id, 2mm apart). Power source would be from a high pressure portable source (I'd be using a compressor with a onboard tank). Each barrel should have a small extension which actuates ...

I'd say 1 is your best bet, so golf balls are good..

Not half bad actually...one of the best conceived micros I've seen around here. However, fueling is and always will be your biggest challenge with these things. Thanks, One tiny squirt of a can of Lynx deoderant I have works just fine, but it's easy to put too much in. I've also built a breech load...

This is my micro spud gun. It's also my first (working) spudgun.
