SpudFiles

Finally finished!!! After a couple months, I finally completed this beauty this morning in time for tonight's festivities. The chamber is 16 inches of 4 in pipe, and the barrel is 38 inches of 2 in pipe. It uses cam lock fitting for burst disks and breech loading. The quick vent is just a street elbow connected to a ball valve and quick disconnect fitting.

It went through the carboard backdrop and blew a hole in the goddamn fence. Talk about power.

holy eff. what did u use for ammo that it went through the fence. i just build a combution just like that but bigger. do u use propane??

Nope, I use regualr right guard deodarant. The ammo I used was a dart- a 2 in wooden disk with a sharpened 3/4 inch dowel bloted into the center. I was amazed at it too, my dad almost grounded me.

y, because u destroyed his fence, id be pissed too if some kid with a spudgun blew a hole in my fence. u should hook a propane meter system to it

Edit: does that beast have a fan?

Nope, the propane goes into the quick disconnect on the side, i'll get some pictures of the meter later. It doesn't have a fan, I connect it tothe compressor to vent.

I was using a burst disk when I blew the hole through. my dad wasn't mad about the fence, he was upset because he thought it was too powerful.

too powerfull, hahaha, nothing is to powerful, except maybe some hybrids. so is ur dad going to let u shoot it anymore?

Yeah, as long as I don't blow through the fence again, or somebody's house.....

how are u going to not shoot through again, put up a LOT more cardboard and some plywood?? lol. i wonder what ur dad would do if u made a hybrid thats a lot more powerful then that.

how old are you mate, u said ur dad nearly grounded u

14 going on 15 in a couple months. He wasn't mad about the fence, I think he was mad that I made something that powerful. He though i was messing with stuff I didn't understand.
Oh, and Walrus, I a making a hybrid. IM me for the details.

Do hybrids out-perform really good pneunamics?

Straying off-course...
Hybrids <i>can</i> outshoot any cannon opperating under about 200-300 PSI, because a burstdisk is the best valve you can have. Of course, power will vary depending on chamber volumes and what not (most hybrids don't have insane ratios, unlike some pneumatics), but the pressure alone gives you a general idea of what you'r dealing with.

dude thats f;ipping sweet put i dented my car my 1971 dodge charger put i dent really bad and it was my weaker cannon
im also 14-15 in 2 days birthday money is going to this
