Electro Powered paintball gun?

[El Pipi Fantasma]

I was wrong about the thing having to have a gearbox of the appocalypse. Being that the Bands would be just over 2 feet long (on a 12in barrel), the bands would only have to spin at about 150 rps. This means that the thing would have to spin at 9000 rpm. This speed can be achieved by a dremmel hand tool. You could use the dremel on a 12-24v power scource to achieve this speed, granted you may have to modify the dremmel. If you could find a dremel that ran off of a rechargable battery that is contained inside the toold, this would work even better. I will most definately try this idea once I get back to the states. This will be in a year, so I will probably post some more before then.

Paint Blender....

Using wheels or a belt to 'throw' paintballs would just reult in lot's of broken paint.



Think about it. The wheels or belt would not accelerate the paint to 300 fps, they'd just grab the balls immediately at 300 fps. Doubt paint can withstand that kind of force.

Maybe belts could work, but you'd have to figure a way to alow for slip to let the paintball accelerate under tolerable forces.


*edit*: I also think your RPM calculations are off.

..going with this idea of belts or multiple sets of wheels even.. about the only way to accelerate a ball to 300fps would be to have the belts slightly wedge out so that the ball is gradually introduced into them (how to feed i dunno??).
the multiple sets of wheels would have to be stepped increased in speeds of the next set of wheels on down the "barrel"..

oh and El Pipi- your calculations are wrong about the belt speeds. you seem to be trying to figure the surface speed of the belts, given one full rotation of THEM in a minute. your not accounting for how fast the wheel would have to be spinning which is turning the betls. IT (the drive wheel(s)) would have to be rotation at a very high speed.. for a 2" diameter wheel driving ANY length belt would have to be turning in the neighborhood of 68,755 RPM to have a surface speed of 300fps. put anyting you want on the that surface (belt, ball, boogers, etc..) but it will still have to be spinning that fast.

out!

a totally electronic gun would be awesome. a gun that uses a battery to somehow create pressure to shoot a ball. I've wondered this miny a time my self in the past.

[Coaster]

or.. use a motor that would compress a cyclinder of gas. The gas would then fire the gun.

i skipped most of the posts, but read a bit of telefragged.

his idea may work..

a rail gun is what i had in mind when i read the post first.

my friends and I tried to make one for a science experiment. granted it didnt work, but from what i understand it can. when you read into it a bit, it can be fairly simply to understand. making it is a bit tougher :]

it would still suck the power and be tough to launch a paintball through it

two other things..

someone mentioned a belt that was goin 70,000 RPMS would tear a ball apart. in deed it could, but im sure that is what they though a bolt flying from a HPA marker would do way back when this all started..

also, chronoing could be either easy, or extremly difficult.
maybe if it was somehow based on electricity, it could be easy to dial in. somehow i see a electro rail gun being extremly consisten and easier to work with then the belts.. but who knows, i am 17 and in high school

[mag-nanamus]

i think the major difference between a rail gun and a conventional marker is the bolt starts the acceleration and the air increases it. with a rail gun i think it would be like hitting the paint with a baseball bat.

[felony]

you would be right.

unless the speed could be controlled?

if i remember correctly, isnt it magnets for the rail, and basically a huge ball of wire on the inside that has a large electric current?

maybe the electric current could be controlled. less at the initial impact and full force at the end.

of course, i could be all wrong with my idea of how it works..its been along time :]

! or you could use compressed air so it could be more consistent then co2! ..doh i forgot tom already made that. I think we should make some paintballgun that feeds through clips that hold bullet shaped paintballs. Tom did a test..or someone and showed that a bullet shape is far more accurate and aerodynamic. we just need to produce the balls somehow and make some massive sized clips...that are affordable

[chris99506]

the airsoft gun concept wouldn't work it would tear the ball apart and so would the belt idea, it wouldn't go through the barrel and it would be horribly inaccurate the best bet is a self recharging air tank like the ones on certain nail guns but it would be hard to make it operate at the same psi.

[Micromag Sith]

a paintball rail gun huh? well when you can make it small enough to hold in your hand then you can tell me how make a lightsaber he he he

[trikonx]

what about nuclear power im not quite sure if this works the way i think it does but correct me if im wrong the unrainum or what ever boils water which turns turbines so we make this the size of tanks but after a day of paintball you might glow but while we are throwing ideas out i figured i might as well throw mine

[hitech]

Another idea would be to have a solenoid drive a large plunger that build enough air pressure/volume to fire the paintball. It would be large and heavy.

[madgoat33]

A rail gun wouldn't work. Paintballs would have to be magnetic.
