Wide View of Cannon

View of Fan and Dual ignitors

Close Up of Control surface

Please let me know what you think would welcome advise-I am going to start work on a pnematic one next

I usually don't like the look of PVC, but when its painted that well it looks great.

Is that a stungun ingnition?

What width is the barrel and chamber?

Thanks for the comments-
The ignition is simply a grill ignitor that I split to three points . (I have been experimenting with a converted disposable flash but haven't gotten as hot a spark as with a grill ignitor.)

The Barrel is 1.5 "
The Chamber is 4"

It makes one hell of a boom with Aqua Net.

The box holds a fan circuit that runs for about 20sec when pressed. It is housed in what is best described as an Altoids tin.

Nice first gun! Metered propane is a great plus, but I definitely give you brownie points on seeing the pluses of a fan, even with hair spray.

nice cannon dude, i like the paint job

Thanks
I am considering propane-This was a small comission for a friend who paid me for expenses so i did not want to go to pricey. I would appreciate advise on what next. Should i go for a propane fueled gun with a stun gun ignitor or try my hands at pneumatic? I do like the hell of a bang that comes from combustion. But would like the power of pneumatic. I really like building them more than firing so I'd have to find someone to sell it to. I'd just sell it for cost so i could go on to the next stage.

Mark that is one wicked gun in your avatar-That barrel looks better than six feet?

It's five feet of 2-1/2" SCH-40.

Oh I do expect the pnuematic powered cannons to go boom. I'll add longer barrel and more precision combustion chamber to number three cannon.

Thanks

Nice cannon for your first. The paintjob looks awesome. I would just recommend not using hairspray just about anything is better than that. What size fan is that? Where did you get it?

grendal · Wed Nov 15, 2006 10:03 am

Thought i posted this reply already but it does not appear-sorry if repost.

What fuel do you reccomend? I intend making a propane after the pnuematic. I gave this one to my friend Gbeast so i don't want to mod the gun but if there is a better spray fuel I'd like to recommend it to him,

Anyone tried aersolized alcohol?

The fan is puchased from Radio Shack. It is a 12 volt model a little under 2" in diameter.

Right Guard, Axe, Old Spice they all work well and the right gaurd has to be the old formula mine says 1998 on the can.

nice job I recon u should decrease the diamater of the barrel and enlarge the combustion chamber though. If u can
