My first cannon(minis dont count)

Unread postAuthor: jjjd » Sat Dec 02, 2006 10:15 pm

This is my very first cannon, it only cost me $30 canadian to build and i will ge making it propane over the weekend, the fan is from a hairdryer you see at hotels, the switch to operate it is the hi-low switch off of it, and i have a twist sparker from an old bbq. It has a 3" combustion and a 2" barrel

Mixing the fuel and adding turbulence for a better ignition. Look it up in the wiki.
