You don't have to make the cannon exactly like mine, as long as you keep to the same principles of how piston valves work, you can make your cannon look like anything you want.

Check out www.spudfiles.com for more information and inspiration. It's the worlds largest database and commmunity for spudding.

Firing the cannon:
Make sure every single part as had 24 hours to dry before firing the cannon. Simply hook up your air source (you'll probably need an air compressor, not a 12v compressor), open the ball valve, let the cannon fill up with air, close the ball valve, aim and then to fire just pull on the blow gun handle.

If you have any problems with the cannon, go to www.spudfiles.com and make a topic asking for help.

Or you can email/MSN me, go to spudfiles, find the member 'MrCrowley' and click on the MSN email address

Haha, Thats only because youve made like 20 SpudGuns. Ive made a Ball Valver and Sprinkler Valver (My Sprinkler valved one is on Instructables) Beginners will find that shooting is the best part, but then it gets more boring and designing it gets really fun.
