DAMAGE AT BOTTOM WITH VIDS AND PICS
MORE UPDATES AT BOTTOM
CINDER BLOCK SHOT VIDS AND PICS AT BOTTOM
PAINT JOB PICS AT BOTTOM

Here is my new golf ball gun. Just your run of the mill 2" piston valve with Hubb's design of piston. I have to thank Hubb a lot for this build as he helped with a few things- The piston, modding blowgun, adjustable hop-up, detent to come also. I also have to thank MrCrowley for the inspiration to build this, it was pretty much modeled after his cannon with a different piston and different stock design. Heres the specs:
Chamber- About 7 feet of 2" pressure rated PVC
Barrel- 5 feet of 1.5" sdr 26, yes I know, not a perfect barrel, but I wad the golf ball with some paper towel.
Valve- 2" Tee 1.5" porting barrel sealer
Piston- 1 1/4" coupling plugged and with built in check valve
Pilot valve- 1" Orbit modded sprinkler piloted by modded blowgun
Bumper- Currently some car wash sponge foam and rubber disks, I don't trust it. I put a little piece of rubber garden hose in the inside to reinforce it and open up the hole to the pilot more. I will upgrade as soon as I can get something better.
Until then, I'm sticking with 30 psi.
Which seems to be enough, because it can already punch well through my wood fence, which is about a half inch thick. The golf ball goes past it about 30 more feet.

Pressure gauge and paint job, black fittings and camo pipe, to come when the parts arrive in about 10 days.

I only got one video of a low pressure test fire-

This thing is a beast. It is so loud when dry-fired even only at 30 psi. It stands 7 feet 7 inches muzzle to shoulder rest.

And that's Superna

*Updates soon*

I have added a new bumper, it is a raquet ball cut in half with a hole in the middle. I have taken it up to 60 psi now. Do you think I should go higher?

DAMAGE!!!

Hole through fence at 30 psi:


All the shots after here were done under 60 psi.

After first test shot at wood plank:



Note recoil on the first two videos!

After all shots (lol):


MORE UPDATES

Added muzzle break and front sights:



Added rear sights, o-ring detent(thanks Hubb ) and what I call a slide lock bolt action breech:



Added better barrel supports with repair couplings that the pipe slides nicely in, no modding. I need to get another hose clamp for the bottom one, for now I just hot glued it.


OMG I LOVE THIS THING

Another UPDATE:
Decided to shoot a cinder block.

Path the golf ball took after it ricochet'd off the block, note my boat and camper:


That's what not to do when firing a golf ball gun

UPDATE! Painted the gun, used krylon fusion.



Hope you like it.

Very nice!!! Albeit in the wrong section...

Like the hopup, have you shot it with a barrel on it yet things a monster can't wait to a updated vid

Yeah remember if you read you would know I put it though wood at 30 psi already.

Very nice!!! Albeit in the wrong section...

Thanks, and thanks. I was almost certain that I put it in the showcase... damn.
MODS PLEASE MOVE, THANKS.

I don't read every post but you should post damage pics

I can't, its dark outside.
Tomorrow I'll try for a video and damage.

Ok how thickset your fence, funny enough I shot my metal fence by accident and bet a the wire after I shot it through a piece of plywood

the fence is about 1/2" thick. I shot my speed limit sign with it and it put niiice dents in it.

Speed limit sign , like a real street sign, isn't that illegal

Ahhh, who cares...
I gotzz two of them
Pics tomorrow

whered you get them from

Very nice cannon. Did you draw some of the design from Crowley's piston guns?

Also, don't shoot street signs.

I don't shoot the ones on the road... We have two that we took off the side of the road sort of as a protest that we wouldn't have people driving 30 mph down our road.

The gun is modeled after MrCrowley's, yes, but stock is different and the piston is different. But he did inspire this gun.

Nice cannon... If I remember right, this is your first golfball gun right? Good job. I want to see some damage...

Yep, first golf ball gun.
It's also my first perfectly working piston valve. There is practically no leak. I will hook up a gauge and wait to see if there is any leak, but I dont think there is. Pretty awsome. I'll get some good damage pics tomorrow after school. Thanks
