my question is: what are the difference betwwen the types
what kind should a newbie like me use and startoff with
is there one that can be used as a paintball cannon?

thanks for the help.

I Belive For A Paintball Gun My Best Preferance Would Probably be a Pneumatic One... It Is The Better One I Think

I'd like to point out that the pneumatics can generate speeds way too high to safly use for paintball. You can put non-frozen balls through those 55 gallon plastic barrels, and that's not with a insanly sized gun.
A combustion could be done, but then again, those things can shoot very fast too.

My advice: if you build a paintball cannon, do it for the eaze and commoness of the ammo, not so you can "safly" shoot people. Because you can't.

Most people start off with building combustions then moving onto pneumatics... I suggest playing with a midsize combustion first and see how it goes.

ive never made a combustion, but would the flame busrt or rupture the paintball or do i just have no idea what im talking about??

well, the combustion only lasts like a millisecond, so it wont do much damage, and someone on spudtech (Dex?) built a combustion paintball gun without much trouble

i really don't think pneumatics are too powerful. Correct me if I am wrong, but pneumatics means it uses compressed air (Co2) to shoot, just like a paintball gun.

go to http://corin.com/bill/paintball/aircannon/ on that site you will find a sub-page http://corin.com/bill/paintball/aircann ... idges.html. Now, if you used a shell like that to launch the paintballs.. that would be freakin' awesome! I'm working on a design right now for a pump action launcher like this to be mounted on the back of a vehicle

OK DUDE that is BULL CRAP about how u said that air cannons have less or little power air cannons have way more power than combustions and they are the best thing that u can make (afodably and other reasons)



that site is when i bult my first cannon i recomend that site if ur a noob but the hard part was the wireing i think when i did it but i recomend it for noobs

Noooooo, really? Couldn't resist the opportunity to be sarcastic.

The valve in a paintball gun only lets out a small bit of CO2, a hammer valve, correct? The sprinkler valves we use have a flow rate, and let out all the gas very quickly, because of a faster opening time. Add that to a longer barrel, and you have a VERY powerful gun, to dangerous for a paintball match.

The flow of a sprinkler valve is phenomenal compared to a hammer valve of the same size, I think.

Hey I'm back just really quick, here's the design I've been working on, http://people.howstuffworks.com/paintball-3d-gun.htm has a really good explanition on what my diagram is if you dont get it. Also the pics for the cartriges wer taken directally from http://corin.com/bill/paintball/aircann ... idges.html

le'mmie know watcha think!

PS, i want to get some cad software soon

Noooooo, really? Razz Couldn't resist the opportunity to be sarcastic. Laughing

kk, i just put up a pic of my design, think it would work??

Hmmm, I can't quite seem to discern how it works, other than when the trigger is pulled, that hammer is release. But that doesn't quite make sense. In a paintball gun, the hammer hits a little thing connected to the CO2 line, allowing it to open and realease gas, but that doesn't seem to work that way. Maybe a more clear explanation?

Yeah i understand why you don't get it, i didn't get the concept either, check out this 3D diagram, cleared up alot for me! http://people.howstuffworks.com/paintball-3d-gun.htm
Look closely and zoom in on the cup seal, little holes on the side of the valve tube let air through.

- edit -
you can also go to http://people.howstuffworks.com/paintball2.htm for a written explanition.. i basically ripped my idea off of this

I have a small combustion ,a pistol type that shoots paintballs ,It has about a 10" barrel ,a very small chamber ,I belive about 5or 6" in length with a 2" diameter. most of the paint balls do not blow to pieces when shot but they really shoot pretty hard . I would not want to be shot by it . It will go through a cardboard box.and they sometimes curve in flight ,suggestion they are going pretty fast. It has a handle made from an old chinese type pellet pistol.

A quick run-through with the GGDT indicates that those paint balls should be getting a speed of about 300 feet/sec... typical paintball velocities, if I remember right. (but remember that the GGDT is intended for combustions.
The curving is most likely a symptom of the paintball being launched spinning - magnus force effects.
