2nd Sprinkler Pneumatic

[TheTrooper]

This is my second Sprinkler pneumatic, its powered by a 3/4" Sprinkler Valve and has a 15 inches of 1.5" PVC for chamber and 6' 3/4" PVC for barrel. Using GGDT it averages at 536 FPS firing a 7 gram rock. (Is it powerful? or not?)
Stock is very comfortable and easy to move around, I hope to make it breech loading because Muzzle loading this thing sucks (any ideas for breech loader will help)


Yea i messed up on the gluing part of it get over it!

It would make more sense, both in terms of performance and ergonomics, to tap the blowgun directly into the sprinkler valve.

And why, why the shoe? If you wanted to give an idea of scale, you could have used a ruler...

[TheTrooper]

i have the parts to tap directly into it but i'm always afraid that i'll bump into it and ruin the threads on the modding. It was late at night and a shoe was near so i used that insead

How much power do you think i would gain?

[jackssmirkingrevenge]

You probably won't notice if you don't have a chronograph, but it can't be bad You could always reinforce the threads with copious amounts of epoxy

[TheTrooper]

OH! i forgot to say The stock is blocked and is removable! and yes epoxying things is fun except those dirty evil STOPPERS! (washers with quartes on it) i had trouble epoxing them

Noice. And note: Message too short.

Thanks Nova, yea i've seen the poor-mans breech but i've also been looking into this one: http://www.instructables.com/id/SSPU7XQF6B7Q5Y1/ im just not sure how the cut the pipe that holds the barrel because i dont have a band saw

[Eddbot]

nice, it reminds me of this one, cuz it has the angle down then back up near the blowgun (i just figured out how to use words as links and i use them too much)

while i can see that finding a ruler is way more trouble than finding a shoe (at least in my house) shoes can be in different sizes, hell you could be a size 2 and that could be a mini, or you could be a size 20 and the thing would be 8 feet long...smilie :tongue8:

[TheTrooper]

Its a Men's 9, its a pretty small shoe. Your right, mine and his are very similar except his looks cooler because of the paint job, the silencer, and the ammo rack i need to do cool stuff to mine

[Eddbot]

don't discourage yourself, it's not good for your libido

[TheTrooper]

I'm only saying i want to add some cool stuff to it. But i only have like 2ft of 3/4" pvc left so i wont be able to make anything until i purchase more

[TheTrooper]

I had some trouble, when i went to pressurize it the stock blew off! later i found out that the stopper leaked slightly then slowly blew the stock off. I epoxied it a fair amount and will hope to fire it by end of this weak.

Edit: oops double post

Nice cannon, except for the duct tape. You probably could have took your time and used something better than that duct tape.

[ShowNoMercy]

I agree with that, maybe try some wood as a support? And I am not sure if its me but your stock looks a bit weak. Does it flex a lot? Or is it just me and its sturdy? Other than that nice gun, what color do you plan for it? If any.
