|Decals and Resources
Here's a link to a good potato gun site http://www.borked.org/~wax/graphic.potatogun.html. My cannon has a 1" barrel and a 2" combustion chamber. I use Right Guard as the propellant.
The decals were created with Lotus Freelance or downloaded off of the internet and printed out with Lotus WordPro here. Sorry about the format, I'm working with John to produce a file that can be viewed/printed by anyone.
