ALOHA FROM HAWAII!.....This is my first propane metered combustion. i've built four of these so far for some of my coworkers. This one is mine and it took some time to get everything working right before i could sell them to my friends. i get all my clear 40 PVC from a specialty plumbing supply shop close to where i live. they only sell them in 10' pieces. but i was very suprised at how cheap it was per foot. the 4" costs about $10 per foot,and the 1.5 pvc costs $11 for the 10' lenght. The cam lock cost me about $14.


specs:
4" x 18" clear chamber
1.5" x 5' clear barrel
2" cam lock
80mm blue led fan
dual spark bbq ignighter
2" ball valve to vent chamber
metered propane
custom handel with batteries and wires hidden inside


the paint job and handle is kind of jacked up from all the moddifing i did to it . So thanks for taking a look at it and please give me some feed back about the gun

Very impressive indeed. I am glad to see such craftsmanship. The clear PVC is cool and the paint job is...well...relaxing. I look forward to see more cannons, good job :thumbup: !

Great job very clean. I like the use of the 2" ball valve to vent easier then a threaded cap...

Keep us posted on more builds...

Thanks everyone for the support. My next project will be a pneumatic cannon.........A GOLF BALL MG! I made good friends with the dude at the plumbing supply shop and we are now drawing up some plans. He will be able to get all the pvc, reducers, couplings,....everything at his price. This dude also has a huge compressor we can use. Ill keep everyone posted.

WOW!
I just read the prices you put, and thats amazing!
It cost that much for regular pvc in my area!
I expect to see alot of great things from you and hope you stay in the forums.

Howare the laws in Hawaii about spudguns?
Where do you shoot your cannon?
