Not much to comment on really, typical basic spray and prays. Is there any reason you've built 5 of generally the same cannons without advancing the technology in any of them?

BTW, Welcome to Spudfiles. Browse around some in the cannon showcases. You'll find it interesting I'm sure.

Lol yeah i had the same thought.

Maybe new designs?

Ahh...
Pneumatics :)

Yeah i used to fool around with them.

For starters, you can modify a sprinkler valve-Great tutorial made by PCGUY in HowTo section-


If you're looking for a challenge go for a piston valve. It has more flow :)

You've built five cannons but you're "not really into it that much"......HMMMM.
I would go by some cheap spray paint and hose them down. I like a random camo pattern, it does wanders for the looks of a gun and because it's a random pattern you don't have to worry about being that artistic. Spray on a base coat and add some squiggly lines.
And don't feel intimidated by that first reply, some of US aren't in to fancy pants cannons like hybrids and metered propane and winning a talent contest. As long as you have fun with it then thats all that matters.

OMG You used DWV!!!!
they are going to blow up raining pvc shrapnel all over you :shock:
:lol: Not really, just use pressue rated parts next time, its just safer.
And make sure you use all pressure rated parts in that pneumatic your planning, because those are under more pressure and DWV goes BOOM.

Sorry for that non pressure rated part rant
Cool cannons BTW

Hey, you yourself noticed the 5 cannon zeal.

...and us "fancy pants" cannon boys put em on one leg at a time, just like everyone else..... :lol: :wink: :lol:

Seriously though Kingfish, I don't believe there is a significant we/they thing going on around here. Those are basic cannons, pure and simple. Lots o' fun, sure. Will they eventually tire of them, yes. Especially if they have taken the time to seek out and a join an internet spud forum, chances are good they enjoy the hobby and want to improve.

There's nothing at all wrong with that.
