Help with a pneumatic spudgun

Unread postAuthor: Bluerift » Sun Sep 25, 2005 1:38 pm

This is my plan I want to have a 6 inch or larger around tank thats about 5 feet long. That is connected to a straight 1 inch sprinkler valve. The barrel would be a 1 3/4 pipe about 5 feet long able to shoot golf balls. I want to make a pneumatic that has the most power and range, I can possiblely make with out being extremely complicated. If this idea is stupid can someone point me too another plan or how to make this one better please.

that is alot of air behind a 1'' sprinkler valve. i sugest building a smaller chamber or using dual sprinkler valves. the best solution would cost alot of money and that is a supah valve from spudtech.com or there is a theory article on how to build one on the site

dual sprinkler valves would be a waste you going to need some kind of piston valve unless you had like dual 2 inch sprinkler but anyways they dont make 1.75 inch pipe that i know of but they do have 1.5"sdr21 which is for gb's

If you want to go that big you’re going to need to make your own valve. Check out the how-to page. Valves aren't too hard to make.

Also take a look at this video on making a valve.

That chamber seems a bit big for the barrel i think you might want to make it smaller. Have you tried it on ggdt?

I just tried it on ggdt and it says no warnings or errors. And it should go really far.
