Re: God is not angry..

Well, if the end comes before I get this cannon built then i'm going to be pissed. You took the words right out of my mouth. Turns out there is a large asteroid headed into our solar system.... September 26th should be a day of nasty earthquakes for the entire earth. (Facts based on a single video,...

I've had good luck with pneumatic cannon that use a "in the barrel" o-ring.

But this is for a hybrid, so it might be wise to consider a lost o-ring a possibility.

The key word is relatively . A L31 120mm HESH round has a muzzle velocity of 670 meters per second, that's almost 2200 feet per second. Some how i forgot that firearms shoot things so damned fast, good catch. I do know that the "flarp" i mentioned.... seemed to behave more like a non-Newtonian flui...

I approve of this cannon. it would look SICK painted flat green. Normally i'm not a fan of electrically actuated sprinkler valve... but i LOVE the trigger that you have. Just to point out... It looks like ALL the fitting are DWV. (except the front bushing.) I would advise on your next build, yo make...

I asked at my local fire depo, they told me they sent all the tanks they received to "company X" Company X, when asked if i could have a few, responded with "Do you have a big truck?" I can fit about 100 of them in the bed of my Chevy S-10 There is about 400-500 there that i can have. I'm really onl...

I tried this with a VERY VERY sticky pile of old "Flarp" a kids toy meant to resemble slime. This stuff had spoiled, and was too sticky to remove from my hands without solvent. After placing it into a sabot, and shooting it with a 1.9'' porting cannon at 100psi, it shattered, and came out the barrel...

fire extingusher tanks, have alot of em. selling.

As the title says, i picked up about 15 fire extinguisher tanks, and am just wondering if anyone wants to buy one, or a few. They are a variety of sizes, some of them are still in hydro. Hydro pressure tests range from 240psi to 750psi. Valves are not included, but some of the tanks have 3/4'' NPT I...

Also, my QEV allows pressure to build up when the pilot and barrel are swapped, but it wont fire that way. So if it fires, even just a little bit, i would think it is hooked up correct. The best way, would be to plug the barrel port , with a metal threaded plug, and then place in a bathtub, like eve...

no it needs to be flush on the inside of the block
Actually, it can stick into the "Vortex ring"..... this will however leave you with a cloud chamber, that has a barrel obstruction...aka it will fire like crap.
