V-C4 Combustion Cannon

Unread postAuthor: VinnyC » Thu Apr 27, 2006 5:39 pm

Here are some pictures of my latest creation, the V-C4. It has a 100,000volt ignition, 7 sparking points, a 1:1.5 ratio, two handles, saftey switch, power switch, battery gauge, storage compartment, removable barrel, and much more! Tell me what you think! And yes it fires great! (these pictures are the most recent ones I have. I have modded it slightly since these were taken.)

THE BARREL IS OBVIOUSLY NOT PICTURED! It screws onto the top chamber. The lower chamber is for storage and what not.

Nice gun! But if you had all that space in the "handle" part, why not put it all inside? What in the hell is the screwdriver for?

Well, the screwdriver is so you can dismantle the gun! The hose clamps can come off, and by disconnecting the wires (not pictured) the gun be broken off into 3 pieces. Also, the front-most handle can be rotated 90 degrees if one so desires. I forgot to mention that before. Also, the storage space is mostly taken up by the right guard canister and the teflon tape roll. The rear storage chamber has the back of the taser in it, so you can turn it on or off in there. That part isn't open.

The barrel is 4ft long @ 1.5". I did all the calculations to get "exactly" a 1 to 1.5 ratio.

WOW :shock: I really like this gun, it must have taken you a while to make! All the accesories are sweet, the battery gauge is certainly unique, and everything else is impressive too.

I bet you can put a propane injection system in the lower compartment.

I actually HAVE added a propane tank w/ a clear hose running from the front of the gun into the back of the top chamber now. All the appropriate fittings and valves make it look pretty good. Unfortunatley, this propane rarely if EVER ignites! I have 7 sparking points inside of the chamber, and it is 100,000 volts, but rarely anything happens.

Am I doing something wrong with the propane? I have tried adding a fan, but that didn't help. Yes all the fittings are sealed, I have checked that too. Seems that good old right guard still works the best (doesn't look as cool though).

Most likely your Propane\Air mixture is over %4.2 propane which causes bad igntion, or it could be much less than %4.2 propane

I doubt it's leaks in the gun, maybe dip the propane igjection in water while pressured... check for leaks
