yeah i made one of them a while ago also.. we finished off the potatos and got the bright idea of using other things so we figured out that we could use the plastic bag for a wad and putting MUD into it and letting loose... needless to say it was soo funny from then on all we used was the mud shot.. by the way ours was the fire kind.. made with PVC piping..

hint use grill starter for ignition..

fire procedures for us..

1 put spud in launcher
2 ram spud home
3 unscrew the back and fill with favorite aerosol wait a few seconds(so that it isnt all wet) and then screw back on...
4 get in firing position
5 hit the little red button
6 watch the destruction..

i did that but the problem i had was i used tennis balls and when i hit something the tennis ball decided it would rather fly at me. it hit me square in the forehead, causeing me to fly over backwards and the guy that was there was laughing so hard he wet himself.

I can't believe this thread came back from the dead

[WickeDKlowN]

Holy (bleep)! I want one now! guess ill have to get off my lazy arse and make one now.

[AcemanPB]

do you have a video of that beast shooting?

[Thordic]

Uhm, I could probably get a couple short videos, but I dont know how good they'd be.

[Schnitzel]

wow

[Ultimator]

Me and my friends used to make smaller ones (hanfgun sized) when we were about 12.

We would get some pvc, put a cap on it and drill a small hole in it. We would glue that to a longer piece of pvc (the barrel) and fill the part with the hole in it with lighter fluid from a hole in the top. Wait a little while and stick a spud down the barrel and put a match down the hole and ka blooie ... flying spud. We froze one once and shot it through my wood fence.

[WickeDKlowN]

did you have to drill the endcap to put the air line in, or did it come pre tapped?

I will be answering questions though. So if you have a question ask away. I just don't want the ATF busting my door in or a bunch of lawyers slamming me with a box full of lawsuits.

Its real easy to make so look closely and ask for details, happy spudding. Make sure you use only high strength STEEL piping for the air chamber.

Just think a bunch of pipes attached to the valve with a 1/8 inch NPT fitting tapped into the back.

The rest is as easy as hooking up a paintball gun. Clue: there is nothing but an empty void (and lots of loctite) inside the pipes.

Once again I will be HAPPY to answer questions.

If you atatched some form of disclaimer you'd be all set.

*sorry if one like this has been posted before, this thread was 4 pages long and i only felt like reading the first page*

me and my bro made a "potato gun" a while back... well it didnt actually hold a WHOLE potato, but part. k what we did was got some real thick PVC pipe, it was probably about 3inches or more in diameter, then we got some 1" pipe and a little converter(sorry if its hard to understand, im kinda typing wordy) we use an aerosol hair spray can as the propellant. we put two screws in the larger pvc part, and made them where they were almost touching in the middle. we put a wire on one screw and put a bar-b-que grill starter on the other end of the wire... since the 1" pvc wasnt big enough to hold a whole potato(it was originally intended to shoot grapes, but they werent dense enough) we sharpened the edge of the pvc and we would just dig the pvc into the potato and take a circular chunk out... it shoots a little bit farther than a paintball gun, i took out a squirrel with it i used to go squirrel hunting with it and my bro's airsoft pistol(didnt want to waste paintballs on those little rascals )

[ZSigErik]

wow, this post is back?

Havent seen this since my semi-early AO days...

[RT_Luver]

I wanna make one. how would you attach your tank to it? anyone know how many shots per tan you could get??

[Dubstar112]

Anyone know how much air pressure Id need to move 30 paintballs around 200 fps from a gun wiht these dimensions:

3"x6" chamber
1.5"x3' barrel
1.5" ball valve/ solenoid is an option too.

how woudl i calculate this, or how could i chrono this? Make a projectile with the same mass as the group of paint Id be shooting? and just chrono adjusting hte pressure each time? helpo

[Thordic]

Use a much longer chamber, mounted under the barrel, and you'll run at 120 PSI, tops.

The style of cannon butterfingers designed doesn't work well at low velocities.

[Dubstar112]

I cant go over 115 though, Im using a solenoid sprinkler valve. Ill just have to play around. Im thinking that if I weigh the projected amount of paintballs, then construct a pellet that weighs the same, I could chrono with that? I dont want to kill somone...
