Has anybody came up with a good way to make an artillery piece for airsoft? I did a lot of design work on paintball pieces... but I dont know how to convert them to airsoft... specifically what exactly to fire out of the barrel!
I'm trying to make a PAK type piece... just not sure how to get bb's or whatever to travel a long enough distance... (the shotgun effect made by just shooting bb's loosely would probably not travel far enough....)

The 3rd FJ has constructed a PAK40 air-cannon that launches water balloon sabots.We used it at the last game to devastating effect. Talk to Josh for the details. Soon we'll be constructing another one.

With two inch pipe set as an inner barrel inside your Pak barrel you can design a very powerful "gun" that can launch Nerf footballs an easy 130 yards in direct fire. (Angled plunging fire is much safer however unless you're firing at vehicles) I use a individually built "shell" that slides in the breech and twists into place to align with the inner barrel. It uses a CO2 adapter and 2 inch ball valve with a small gas reservoir and a short section of two inch tube which is just large enough to contain the Nerf rocket. A crew can have two or three rounds ready to go and operate the gun from behind the armored screen. You open the breech, slide the round in, twist it into place and on command twist the ball valve. For effect I add TALC powder in with the nerf rocket so there is a large signature of smoke with the shot. These shells are uniform and also work with my 57mm recoiless rifle replica. You can also pre-load several hundred BBs by placing them between two plugs of foam waffers cut from swimming pool snakes. These flechettes rounds however should be fired in a plunging fire trajectory as they can be quite painfull inside of 60 feet and outright dangerous inside 30 feet.
I'm trying to figure out how to shoot a functional illumination round using a bright glow stick inside a sabot that seperates upon firing and deploys a small parachute to keep the glow light suspended. Obviously real flares are the way to go here but I'm trying to come up with a non pyro lightening system for fire safety.

Production costs in materials (not factoring labor) is roughly 50.00 per shell. A smaller sized ball valve can also be used for a less powerful round. These are very cool but require mature operation for obvious reasons.

The flare idea would be cool. The only problem is that glow sticks don't illuminate very much. Maybe try a solid ball of LEDs that crack open one at maximum altitude, which deploys a parachute that is attached using 550 cord to two D rings( one on either side) inside the now halved ball. Just a concept design, but I'm trying to give you something to work with.
We've got mock artillery on our playing feild.

At the NY game that warlord516 spoke of. I deployed my M2 mortar on my cart to make it mobile. The PAK40 was getting twice the range of my mortar. Josh was shooting water balloons, I was using tennis balls. Until Josh had shown me how to properly sabot a water balloon, all my attempts had been unsuccessful. (Pics of the PAK gun and my mortar on my Mk3 cart.) ww2aa.proboards45.com/index.cgi?board=east&action=display&thread=1187538847&page=1We had discussed about having a artillery battle from opposite sides of the lake, that will truly be fun! Yesterday I extended the length of my tennis ball barrel to 38 inches. This gave me another 60+ feet in range. I may end up adding a booster tank to add to the air volume and increasing range. I'm also making a breech loading barrel for water balloons. ///ed/// |

Water baloons are an idea I was working with for paintball as well, I just wasnt sure how it would translate to airsoft what with the electricity and the some times expensive WWII gear. Since they are already in use though, that would be my prefered method. Nice and cheap and you dont have to worry about recovering shells to reuse. Plus a nice spread effect that simulates a blast radius.
I was thinking of making a simple replica from PVC and steel pipe and such instead of messing with a real PAK gun, I would never be able to mess with a relic like that, or with something that costs so much!

We didn't mess around with a real Pak gun, we made ours from scratch as well from PVC piping.

It looks convincing in the pics too, where did those wheels come from? They really help the look.
