Making ammos using solder is a nice idea. Have anyone else done it? And is it worth making?

Damn, a AA Battery going at around 560fps is pretty powerful.












Nice performance.

Nice gun. Pump it up to 100psi+ and tear some stuff up.

Hi nz_cannons. Those are some nice damage shots.

Hey trae08. Hook me up with some brass.

Hi Maxus. The copper looks nice. What are the performance so far? And how much pressure can the copper chamber take? Your gun is motivating me to design my next gun out of copper.

Damn, nice. What are the performance of the golf ball cannon?

And where did you buy the 1 1/2" sprinkler valve from?

Damn, i could only find 3/4" at the home depots around my area.

Nice gun! I actualy like the stains! Gives it a personality... :D
Might I ask where you got the fps measurer? How long does the thing take to pressurize? Also, I'm not quite sure what you mean by the tire valve popping off. Do you mean that the threads were coming out of the plug?

Hi noob of ...

Nice gun. Where did you find the 1" Sprinkler valve?

Rofl spud yeti. I guess i'll take that as a complement.
I'll try to keep the mess low on my next gun.


So far, i charged the gun to 150psi. One thing i did notice was how the tire valve was trying to pop out. I guess it was a good thing i used the thicker 1.25" valves instead of the regular 0.45 ...

I appreciate the comments guys!

Modding the sprinkler valve made a tremendous difference in performance.

nice gun good job...

question: 730fps seems a bit optimistic to me, may i ask how far away the barrel's muzzle was from the chrony? also wat ammo was used for this shot?

not doubting it but ...

Hey guys. Thanks for the comments.

Yeah, the paintball got the marble beat by roughly 200fps!

I also tried to fire empty co2 cans left-overred from my little bro's pellet guns. Used a 3/4" sch40 pvc pipe to fire it. I was only able to get around 220fps with that. :( It could have been that the ...

NICE gun, too! 729 fps... AWESOME! :D

Thanks.

yea i did have it off i was shooting air soft pellets so i used a different fitting. but at the 400 psi i could not get it off on the quick connect. i had to drain the pressure to get the quick connect to disconnect?

Damn, 400 psi, i want to see ...

Hey guys. Just found out about this section and i guess this is where i post my pics. Messy job i did with the primer, but this is my second one with a modded sprinkler valve and using the chamber as a butt. Would like some rates, advice and opinions on it. Thanks.
