Thread: In-car spud cannon

Compressed air is the way to go. Just get a quick release diaphragm type valve to open the flow to the spud. I used a 40mm Bunnings retic valve years ago and it worked like a charm. You probably can't buy them anymore form there because they have gone all crap quality like supercheap auto....

Anyway air is the best. It might take longer to pump up, but you only get one shot per go, so in the time it takes to pump up 100psi you would have already got out and reloaded another spud Don't use more than 60 - 100 max psi because it goes a bloody long way!

Have you seen the Spudgun Technology center? They have a ton of stuff there, including a PVC combustion powered spud cannon.

Also, they have a rapid fire, bolt action cannon.

Are you planning on attaching this a way so you can aim at least up and down b/c you can always turn the wheel left and right to aim those ways.

You mean Thunderdome isn't real?

this is a crack up

awesome project. Spuds away!

Anyone remember this thread. James Bond-like Paintball gun car paintball gun attached to the car. Not sure if this guy ever really did it.

Anyways, attached is a picture of my airgun that i built a year ago for a parade. It shot candy to the crowd from a pirate ship. http://www.mp3car.com/vbulletin/985866-post49.html <-- small post on the ship with a picture.

The black pipe is mostly the air chamber. The bigger white pipe goes 3 ways. 1- to the air chamber 2-release valve 3-air inlet connected to a pressure regulator ( that way i could dial in the correct air pressure, i needed low pressure so as not to kill someone in the crowd with candy). After the releas valve its just strait pipe where i would load candy into before fireing.

The plastic mount by the yellow trigger is a switch that i used to trigger sound effects from a pc (so that part is not normally needed)

So all you need is an air compressor or airpump (with slight modification to the inlet) to fill the air chamber. Then your mobile to shoot when ever.

I've messed around with sprinkler system valves. Most run 24VAC which is not in a car. but i have had luck with them working. My next air project was going to be an automatic ping pong ball launcher. The loader was my biggest challenge. I think i have most of the parts i need to build it. I just need a 3-4 inch actuator to load the next ping pong ball.

p.s. with candy i used 15-30 psi. if it was a spud with a tight fit maybe 100psi would be more then enough to blow a hole in the car in front of you. I would definatly do some trials with presure settings on the air system before you go out and shoot someone.
