Pneumatic Blowguns?

I have built other cannons, but all of them used ball valves. I was wondering if I could use only a blow gun as my firing mechanism. I don't feel up to modding a sprinkler valve yet. If I could use only a blow gun, could I have a cannon that has a chamber with a pressure rated tube connecting it to the blowgun, then have the blow gun go directly into the barrel?

Yeah you could but it would be extremely weak.

Well If you do use a blow gun you will be looking at very poor performance. It wont dump air fast enough to get powerful shots.

bluetooth beat me :( :cry:

If i do use a sprinkler valve, will it be semi auto. Will I be able to get more than one shot out of the chamber if it is pretty big.

I tryed to use just a blow gun and it just didn't empty the pilot chamber fast enough to accuate the piston valve.

No it wont be semi auto unless you hook it up to a constant air souce.

Is Prof's head a good constant air source?
Prof, I thought if you let go of the blowgun, your valve can re-seal is you have enough air in your chamber(s)?

You can get multiple shots with a large chamber, but they will get weaker and weaker. Also, blowguns are fine for main valves, you just need to be shooting nails, BBs, airsoft, etc.

I have tried it before and it is super weak. Go with a sprinkler.

I made a pretty sick airsoft gun for like actualy airsoft fights out of a blow gun. It worked really well and all you gotta do is keep your compressor up there and it rocks... I dont mean like clouds... It was a gravity feed single shot rifle.

You can see mine in the BBMG/Strafer Showcase. It's posted as The Portable Airsoft Gun. I never got around to finishing it, but it still works fine.

i got a airsoft vortex gun and a 5 gallon tank that i put in a backpack works pretty good as a portable gun, every one is scared to come near me so i don't get that many chances to shot any one. when i do they end up with at least 25 welts. but anyway back on the subject, you can use a blow gun to in a gun only if you plan on firing small projectiles (10mm and smaller) i actually made a pump airsoft gun that used a blow gun valve as a trigger
