All open at once same size hoses,

Here’s the round I can’t post video. If anybody can suggest A faster round let me know I’ll make it. And just to be clear I’m not shooting missiles they identify as model rockets!

What I have is a 26 gallon compressor body shooting at 100 psi is a 1 inch electric solenoid, 4- 2inch modified irrigation valves with 1 inch tubing to a manifold and for 2 inch exhaust pipe going from each valve to the barrel that a 16 foot long and 4 inch diameter. The projectile is 1.4 pounds and...

I just wanted to see if anyone can suggest anything for more power. I have 4 2” valves coming into a 16 foot long exhaust pipe for a barrel. All are quick exhaust modified valves. A 2” ball valve is then opened to fire. A 1 pound project I made of spackle and a 4 inch Christmas globe had a hang time...

Can someone just please post an answer instead of always ratios and different things just how about what psi should we set the gauges to for oxy acetylene.

Here’s my multiball cannon, golf ball with led in it. I have 2 2” and 2 1” irrigation valves modified to dump all the air out of a 26 gallon compressor. Check it out here

I had a combustion chamber made from a propane rank that was modified for this cannon. I had to get the right mix, and about 2min filling it with 02 at 80 psi and acety...
