silencers

[ALIHISGREAT]

possibly I could add a ballvalve between to sections of chamber that could be closed to cut the volume volume when needed

interesting idea but i would never deliberatly spend money on something to reduce the power of my cannons, the only way i would do it would be to lower the pressure for quiet shots.

Ah, but small chamber-high pressure gives better power than big chamber-low pressure...

Acctually I am usually using them - but even when I have them on is quite loud above 300 psi

You may have a problem with the things then. What's the low frequency attenuation on them?

As I said before, HEAL uses a much larger volume of air than that and dumps it much faster - even though my defenders aren't great, it's not that loud with them. I'm considering buying a better set with higher protection, just to be on the safe side - because, as I have said elsewhere, the males in my family have a nasty tendency to lose their hearing in middle age (both my father, his brother and their father have/had hearing aids), and so I want to take as many steps to protect my hearing for as long as I can - I avoid what some people do with ear phones so loud you can hear them from across the room*, and all kinds of things.

*Reminds me of a great quote from Griff Rhys Jones at Live Aid (at the Wembley stadium):
"I'm sorry to interrupt, but we have had a bit of a complaint about the noise ...... from a woman in Belgium."

Ragnarok... my ear defenders are ghetto earplugs.... I made them myslef so I don't expect them to work as good as off the shelf ear defenders...

Today I joined two 2L bottles inline and suprisingly this design works quite well... so well that I can shoot my gun in my basement at 320 psi without any problems....
suprisingly it works better when the bottles are not perfectly tight joined - so when air can escape/leak when firing (tested at 320 psi )

the whole thing was very easy to build and it is as much ghetto as it can be

I am still going to test the same thing with baffels or try filling the silencer with some wadding....

pics soon

Forget about my previous silencer - I built something better

I tried something new and I must say it is really something yhmmmmm.... new....?. I included a schematic in the pic....
I threaded the muzzle of my barrel and put there 1/2" T..... then I wraped a 1/2" nipple in some kind of cloth and joined it with the T.... then I did the same on the other end of the nipple and screwed another T on top of the nipple

my new silencer works almost as good as my previous silencer build from 2X2L bottles but it is much more compact and it also serves as a crude sight...

I must say that it is rather original since it doesn't have any baffles or even expansion chamber.... it works more less in the same way like a normal pneumatic muffler..... sometime ago I had an idea that this might work but I've never acctually tried this till today....

I suppose it could be improved by adding an expansion chamber - but generally it proves that silencers built on this princliple do work

PS. sorry for not adding pics of my previous silencer but I have so much to do these days that I spend the little time I have on testng new designs and improving my gun

That reminds me of a surpressor setup for a tank that JSR posted a link to a while back. Any help JSR?

You mean this one?

Well if I understood correctly it's basically a muzzle brake with a packed cloth "baffle", surprised to hear it works so well to be honest.

woah three words come to mind..... whats the point! [/quote]

The point would be to reduce the level of discomfort of your neighbours when you're testing state of the art artillery systems in the vicinity of civillian habitation

[Novacastrian]

Yes, that be the one! Thankyou for your help kind sir

It doesn't silence the gun completely but it makes the "BANG" at 300 psi more quiet... it is more like a normal silencer at lower pressures.....

well i think that talking about level of sound and using words like "more quiet" doesn't give you any idea about this - I have to find some way to objectively compare sound levels.....

right now I am trying to determine whether it is possible to improve this... i have some idea... i think that i can improve this if i add an expansion chamber (ok it is obviuos) and increase the surface that slows down and 'leaks' the air out of the silencer
