4" to 2" Bell Reducer as a Cannonizer???

Unread postAuthor: ImHUGEnJAPAN » Fri Apr 11, 2008 3:17 pm

Do you think it would be safe to add a 4" to 2" bell reducer on the end of my 2" barrel to act as a cannonizer. I don't think it should be a problem and it should channel the sound in the direction of my target so it seems louder. Besides I think it would look cool.

Why does it need to be loud at the target? Are you gonna use it for something that might break this site's rules? :?

A) don't have to worry about it breaking, won't really be subject to any pressure.
B) what is a cannonizer?
C) You want noise, fire with a burst disc, or if you want it really loud, fire a blank round with a burst disc

I had originally intended to use this cannon for use on the PB field as a grenade launcher or mortar. A cannonizer does not amplify the sound it just channels more sound towards the target making it seem louder. Google an opsgear dishka. It's a device that you screw onto the end of your barrel to increase the report of your marker. It's used for intimidation, nothing more. A bell reducer looks like the Dishka, I thought it might have the same effect on my pneumatic.

It may direct the sound forward a TINY bit.
But no more.

why do you need more noise in the first place?

2, just use a burst disc!! It'll be super loud.

I think because noise impresses people.
A gun that does BOOM give a more powerful impression then a gun that does *poof*
