Taran Ahluwalia: Does anybody know if a hockey puck actually works in replacement of the galvanized steel gas vent tea caps?
man4thwalt: I built this cannon, but it's not working. After airing it up to 40psi, when I open the valve all the air escapes out the rear of the valve. Do you think that I need to back out the barrel a little???
lander holsinger: Could I shoot water balloons out of this with a wadding of some sort
Jeremy Conrad: can i use this to launch confetti?
Rivera John: hey @NightHawkInLight i need help
Rivera John: ive built one but w a lil variation. i posted pics in my paintball chat group on facebook. i would like to tag you and give credit...
Rivera John: hey I got a question. instead of reducing it down to half inch with a ball valve have you tried using a 1-inch sprinkler valve? I used it on my air cannon and it works great. I know I have an air nozzle screwed into the side of it to dump the air but I guess you can keep the solenoid on it and install a battery box and Trigger towards the front of the launcher so you can fire it shoulder-mounted and w a pistol grip instead of turning the valve at the very end. that's what I plan on doing with this design that you have shown us. also have you found an alternate solution for the valve instead of having to fabricate one w those caps?
Krish Pomal: The cannon can also be converted to a potatoe gun
Jmc Trail riders: Why do you talk like batman
fastcar01 For prez: What store did you get your materials from because I went to several different stores and didn't find a lot of the materials
Harry Lim: this guy sounds like cody from the alternate history hub
PinchTune: I want to build one like this to fire little bean bags or sand bags with a thing rope attached to it to launch up at trees to retrieve caught RC mini quads. The sand bag and line would not created as much of a seal as a potato. But, should be enough, right? Also, how many firings can it do before it starts losing effectiveness?
TheCrazyMonkeyKing: hey nighthalkinlight, this is my first time building A spud gun and I looked around f I r a while before I thought that your design was the coolest but i have a few questions. While building the cannon i had accidentally attatched the 3" Coupling to the 3" pipe before installing the rubber toilet bumper in between them. I don't think it would have caused an issue with the piston but I'm not sure. Would it? I've just finished building the cannon but while filling the chamber with air, I can feel air leak down the 1" diameter Barrel. I thought the piston wasn't seated properly on the 1" pipe and I've tried to double up the rubber on the piston. After that didn't work I put a cork sheet on top of that but the air still leaks. I've sanded the end of the 1" pipe pipe flat and im wondering if it would be a good idea to cut the 3' 2" barrel down to 3' 1" or 3' or less? I'm also wondering if there is another material I can use to provide an airtight seal or if is there another piston design I could use. Thank you ahead of time and I'm open to any suggestions. I'm really exited to shoo this cannon.
Matt Clark: put a handful of airsoft pellets in a piece of paper and ball it up and throw it in and you got an airsoft shotgun
Dominic Abrams: what would be the distance it can shoot??
Master Caster: I dont get what makes the air chamber. I get how it works, How far does the piston travel before it stops ?
Aktiv Players 04: why no slowmotion😕
rm “ZHARDuM” zeta: how many yards?
Justice Smith: shoulder mount it
that one ugly kid: use 100 psi for this kind of pipe. and if you make a smaller one you can use more.
