Mick,
My air cannon came today. I lost my first golfball
somewhere over Canada!!!

Hello Mick,
Heres a photo of my completed Thumper
(Viper golf ball cannon).
I went with a camo theme instead of Star Wars.
I epoxied all threaded unions except the female barrel
threads and the trigger. I went teflon tape on those.
No leaks detected.
I made three braces of 1/2 Gatorfoam, and
fiberglasses them for strength. They fit the barrel
and air cylinder perfectly, with a 5/8 gap between
barrel and reservoir.
Black zip ties lock it all together.
Since I live on a private golf course, I can safely
let the Thumper stretch its legs in the backyard.
Wow! I am amazed.
The hang time for golf balls is more than eight seconds!
If I dont use high visibility orange or yellow
golf balls. I cant see them after five or six
seconds, but I can hear them Thump when
they land.
Good thing there are so many poor golfers in the
club.
It guarantees a fresh supply of free golf ball ammo
bouncing off my roof and my pool enclosure every day.
I need to get a rangefinder to check maximum range,
but its way over 200 yards.
I havent dragged out my old Caldwell chronograph
yet, but Im guessing velocity at the muzzle
will be 600+ feet per second.
Once I get some numbers Ill pass them on.
With the weight of a golf ball, that is a lot of foot
pounds energy for air power.
Not a toy! is for sure. Quiet too!
Im gonna buy a bunch of wildflower seeds and
shotgun them into a field nearby to see
if it seeds a large area.
Its great. I love it!

Mick -
Thanks again for the help. The irrigation supply company had the 1.5"
Class 200.
This was a fun project with my 13-yr old son. It works as advertised -
easily shooting 600'+!

This made an awesome Christmas gift for my sons.
Nothing says happy holidays like launching golf balls a couple hundred yards!
Great simple and safe design.
Thanks,
Tim
