Repeating Pneumatic Tennisballer RPT V.2

This is the V.2 version of my tennisball gun centered around a 1.5" pneumatically modified irrigation valve. I bought a breech loading tennisball barrel from http://www.launchpotatoes.com and designed the rest of the launcher around it.

Nice! I like the grip especially, that's one massive valve :)
Oh and cool camo too :wink:

yup that's a bigass valve

but that elbow looks pretty scary, are you sure it will handle the stress ?

Thanks, this was mainly an aesthetic+ergonomic build, so I guess it better look the part :D

@POLAND_SPUD, it's a standard SCH40 PVC street elbow that was screwed all the way into the valve thanks to some torque provided by the barrel length, so I don't think it should fail at sub 120psi pressures with relatively light ammo. Thanks for the concern though, I'll keep an eye out for stress cracks :wink:
