Cool, but don't expect very impressive power. I would leave the extra's for your next cannon, may I suggest a sprinkler valve?

Well its clean for what you made, not that bad. I suggest you look around at the wiki, before wasting money and time upgrading this.

Have a go at making a gun with a sprinkler valve, mod it if you want to, and then use only PVC pipe not soda bottles.

Well there is nothing wrong with metal either :wink: Anyways it looks ok but as others said it would be a wise desicion to save all those upgrades for a better gun.
Yeah, it's that important.

I would suggest you move to a 6mm barrel, you'll get much better velocity. Using a blowgun as a valve isn't really good for anything above that calibre.

another Aussie. good stuff. probably too early to delve into it, but save that blowgun for a nice copper piston gun, then incorporate that into a stock, and then you can add your scope and paintjob :wink:

If you used copper you could run much higher pressures and use a shorter barrel/chamber and still get higher performance.

It's a good start, though performance won't be too excellent. You'll really enjoy it when you move up to a more powerful valve.
