I'm working on a Nerf Gatling gun but one thing I can't quite figure out by dissecting guns or looking at plans online is just how they are actually propelled. Maybe there's a few different ways?
as long as I'm going thru the trouble of making this including casting my own gearing and whatnot I don't want to harvest plastic guns nor be dependent on purchasing guts from someone else.
Theres not actual connection between the plunger and the darts, right? I'm kinda flummoxed though because to test I took a screen door pneumatic and rigging up a dart holder I did a full "shot" and it made it like 20 feet -- and that has a serious spring to it!
I've seen plenty of videos of it and read things but I must be missing something basic. Please clue me in.

I've taken a few apart. It seems to me some sort of pneumatic/spring hybrid. I know I took one down and took out what appeared to be air restrictor plates. That thing was wicked.
I have it on good authority that compressed air works to shoot darts fairly long distances. I forget the bust up pressure though, I think it was 50psi before the darts just exploded.
What method would you use to get there? I'm thinking a simple spring being compressed behind a piston in a long cylinder, which draws in air from the front and expels it from the front too.

These guys seem to have figured it out: Supersonic nerf darts
In reply to P3PPY :
I took my cue from Toyman, half inch pvc and a blow gun.
If I was going to translate that to a gatling gun, I think I would go with a vertical magazine above a stationary chamber, then spend the next several days cursing trying to line up a revolving barrel assembly, before giving up and looking for an arduino controlled servo system.
In reply to RevRico :
Not to give away my patent or anything but I'm using the gap between the barrels to feed the belt ammo
A nerf gun is a human-powered air compressor with a foam dart stuck in the outlet. The human puts tension on a spring and then releases it (usually with a trigger but sometimes directly as in the "bow" type), which allows a sprung piston to drive air into a barrel and propel the foam dart out.
