Ron Burgundy

Unread postAuthor: Mr.E » Fri May 18, 2007 4:44 pm

Built this thing about a week ago out of ABS. 3'' chamber with a 1.5" barrel. Shoots pretty good and sounds like a friggin bomb going off. Me and my roommate named it Ron Burgundy. Enjoy!

Here he is in all his glory. Pretty ordinary, but pretty effective.

The igniter. I thought it might not be held in strong enough, but it seems to be fine.

The spark. Pretty small, but works fine.

Some custom ammo. Styrofoam with a 3" screw down the center. Flys pretty far.

Well I congratulate you for taking the well worn path into spuddom. This is a nice cannon to start on. I hope you continue building them :P

Thanks guys. I already have plans for my next one. Gonna use steel from my buddys shop and make it real nasty looking.

Around the igniter thats ABS cement. I was worried about the pressure blowing the igniter out, so i layered the cement on a few times. Looks like sh*t, but im gonna paint it soon anyway.

You can get it to work, you just need to insulate the electrodes so they're not incontact with the metal. You should use the metal to make a pneumatic instead, as it can take higher pressures then PVC.

I need to buy a compressor and valves and fittings, etc though. Whereas i could go and buy some ABS for like 30 bucks and blast spuds with fire and explosions and all that good stuff. But i will make a pneumatic soon enough.

Well its your decision, just saying that you can take metal to 600psi safely depending on its rating and get alot more power compared to 40psi from a hair spray combustion.

Hair Spray combustion no, propane metered combustion(if made correctly) yes.

The pressure spike in a metered propane powered launcher is actually around 55psi. For a hairspray combustion, you would be lucky to get 30psi.
