"So, if you did build it, did does it work? How much is do you expect the sound to be reduced versus the affect on the muzzle velocity? " -jimmy101

i built a cannon with a silencer that had the baffles in front of the barrel...it does work, but not as well as i would like. in the first post with ...

i would also suggest adding something along the lines of a gas redirector (something that you would see on a Barrett M109, or other .50 cal bmg) this still wont 'suppress' the blast, but it will redirect the cold and warm gasses in multiple directions... remember; nothing can completely silence the ...

um, i use subsonic ammo for my firearm, and my firearm baffles are make of steel, not wood... i would be careful filling the expansion chamber with steel/wool (steel wool can burn under the right conditions) however after burning; the steel wool will likely still help suppress the sound; I do not ...

ahhh, it is the suppressor itself that is taxed and must be individually licenced. but only suppressors that are capable of being fitted to a 'gun' or combustion capable object are taxable and regulated... thus a paper towel roll filled with wool (that is not fitted to a 'firearm') is not illegal ...

Maniac, the point of my thread is not to debate the classification of a potato cannon (this seems to be a misconception) the point of my thread is to provide a scientific insight for peoples interested in the acustic ...

you are right, a potato cannon is not classified as a firearm. the suppressor is classified as a class three firearm if it is used on anything that is capable of shooting a projectile using any sort of combustion...the point i was trying to make is that it is the suppressor that makes this illegal ...

so im not liable when they do it... illegel or not, it is still fun to do. i may try to get a video of the cannon without the suppressor and the same cannon with the suppressor so people can compare the sounds... but it wont be up for awhile.

PS. i like the suppressor idea (and posted this thread ...

Spud Cannon Suppressor
Ok, I know this sounds counterintuitive but when i built my cannon; i did not want the thunderous BOOM of an internal propane explosion. I own multiple firearms and have a licence for my AR (M-16) pre ban rifle's suppressor. I began to wonder; is it possible to muffle the ...
