Yup. I did a base coat of green, then you hold leaves from what ever you want over it. For me it was a small branch off a tree in my back yard. Then do a very light burst of the different color paint over it. My newest cannon "Rambos little brother" uses three paint colors...the extra color gives it an even more realistic look.

Can you list the parts you use with the "t" chamber, its something that has greatly appealed to me and i was considering makeing my next gun with a similar chamber.
Props dude, and sweet paint job btw!

Start with a three inch cleanout "T". You will need three 3" to 1.5" reducers, a 1.5 inch threaded insert and cap for the BBQ igniter, another threaded exit for the large ball valve (I cement the threaded ball valve in but not the top ignition so I can fix or replace if needed), then last is a 35 to 40" section of 1.5" barrel. All other parts are not necessary just for looks. Good luck

Wow, and by that I don't mean World of Warcraft.
That is sick.
Judging from the size of the cannon and its relative dimensions, I'm going to guess you have a rather high C:B ratio.
And dude, if you don't have everything solidly cemented already, I'd suggest changing the connection between the chamber and the barrel. Right now, it looks like the connector could be limiting the air flow, thus restricting your maximum speed.
But it's still totally sick.
Got any damage shots?

Nice cannon but what of that Blanket? It has a distinctly crime-scene feel to it :?

The blanket is just a moving pad I use for painting. I am in the process of planning a larger, more involved gun. Will post soon.

Hey Utz, was just wondering about that cleanout T does that have somewhat sharp points on the inside of it where everything comes together i think i seen one at ACE but i wasn't really paying attention to the outside when i stabbed myself in the hand

Yea, that's definitely going to get you at least a tazer.
