Blue Thunder Tennis Ball Launcher

Unread postAuthor: cwazy1 » Sun Sep 23, 2007 11:12 pm

So this is my first air powered cannon and i am starting to really like air instead of combustions. So as the title says, it shoots tennis balls, and im using a modded sprinkler valve. The only down side is that the chamber is only 2". I couldnt find 3 or 4" .

Great F*cking Job man! Good paint job, nice job on the handles, and as far as I can tell all parts are pressure rated.

That's a pretty sweet cannon bro. This is what I like to see, a newb with a really awesome first cannon. Keep up the good work man.

Much better than my first air cannon. When i made my first air cannon, it had a modded sprinkler valve but that didnt have enough flow and it didnt work as well as a ball valve which did much better because of the flow. Nice for a first and a paint job. I'd be to lazy to paint my cannon. :lol:

Sweet, what range are you getting with those tennis balls? Bout the pump, when it reachs 97 does it jam or die or blow up or leak or get infected or kill you or what?

That is awesome for even a second or third cannon. How did you get the nice clean paint lines, what kind of tape did you use?

haha thanks guys!

I use "used" blue painters tape that my parents already used on the house. . .also newspaper :D

The pump im using is a really old bike pump, it just doesnt let me pump more. i have to have like 3 ppl to sit on it before it does down. so like with the pumps you guys have, can u pump to 120psi or is it really hard?

I'll try to get some damage pics and i know that it shoots like about 300 yards at the highest psi i can get it to (90-ish). Im bringing it to tennis practice on wednesday so we'll see what we can do then..hahah
