Well Watto thats why im posting this forum .... to get more information on the subject. Im lookin for as much help as i can get and hopefully i can get this design perfected and ready to build as soon as i get home. For everyone else let me know what you think and what might need to be done because ...

No ive just seen alot of people with the coaxial design and since it may take more juice and more chamber to fire properly with just the larger barrel , i decided that this might be the way to go . Not only have people sleeved copper barrels , i have noticed that some have also sleeved pvc as well. ...

Heres what i have drawn up to think about doing . Still needs work. Its a rough drawing on my computers paint program . i want the barrel to be about 7 to 10 feet long and the chamber im guessing roughly 3 feet long. Im not certain on the dimensions of the chamber and really need input. Thanks

Origin Unknown Thanks for the spring idea that will add a cool effect to what i have in mind. I am planning on building , umm i guess its a Coaxial Combustion Cannon.... big barrel with smaller inside. I would upload a pic i drew up but not sure how yet.[/img]
