Re: Impulse Water Cannon any idea???

The link is lost but I presume you're talking about the spyra water gun with that big Kickstarter campaign. I would look at a water pump like this 12volt RV water pump with a built in 80psi cut off https://www.amazon.com/dp/B074MZYS37/ref=cm_sw_r_apan_glt_fabc_MK5936AWFRVX9PYWN9DA?_encoding=UTF8&psc...

Re: opinions needed on concept

That's an interesting use of an air cylinder, but you really have the same effect from a QEV or a more common homemade piston valve.

Re: Rapid firing air cannon?

You need to shut off the air feed or the recharge rate will effect the projectile velocity as the tank discharges. This varies on factors like ballast size and operating pressure. Smaller ballast needs higher psi but gets more efficient as you go. 800psi can be used in quite a small ballast and prop...

Re: Some 3d printed ammo

Hi, I’m not sure if you are still monitoring this post, those red finned projectiles are awesome, where did you get the file from please. Did you print the launcher yourself and the same for that did you download the files for that.

Shotgun style grenade launcher from SPUD COMMANDER

Here is an interesting design we came up with. Its a cross between a shotgun look and grenade launcher. I added a homemade stock to the rear and sprayed the barrel black as well. We call it "The B*tch"!

Here is the demo video:
