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 don’t use high visibility orange or yellow golf balls. I can’t 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 it’s way over 200 yards.

I haven’t dragged out my old Caldwell chronograph yet, but I’m guessing velocity at the muzzle will be 600+ feet per second.
Once I get some numbers I’ll 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!

I’m gonna buy a bunch of wildflower seeds and “shotgun” them into a field nearby to see if it seeds a large area.

It’s great. I love it!

Since the trees are over 100 feet tall, the air cannon is the only way to launch a lead line over the tops of the higher branches.

This cannon is also a great source of entertainment when my grandsons come to visit. As you can see we had fun painting it with some spackle furniture paint.

These cannons are the best…

My students and neighbors really enjoy it. We appreciate your plans.
