Thanks for the good answers, I’m compiling them and consolidate so after a while more, i’ll post some sort of “conclusions” (and side comments) and start another Post with other parts or sub-assemblies. Of course I’ll post my own ideas. No hidden intentions here, just trying to put some “whys” on wh...

Why Suppressors work: REAR CAP & TUBE - (I)

This is the first of a series of threads focused on “Why Suppressors work” not in “How/What Suppressor work”. It’s open, no need to be a Guru on Suppressors, just for those with common sense. Everybody is welcome as long as they drop down their best guess not what others make and “work”. If I see it...

Re: Supressor Baffle Pics!

These Baffles are great but sorry, no; it’s not due to the better cooling but due to the suction effect they create. There are two variables to take into account: Number of flutes and flute radius (angle of cut). If you can afford CNC Manufacturing, these are champions for full auto center fire Can...

Re: Supressor Baffle Pics!

http://i.imgur.com/69WiYHW.jpg So, those spiral flutes in the cone baffles add torque to the gas flow thereby tightening the suppressor? No, they just redirect the gases to allow it to cool down longer. These Baffles are great but sorry, no; it’s not due to the better cooling but due to the suction...

Re: difference diameters

In general, Bullet diameter must be smaller than “Silencer hole” (no fun for the Bullet and no fun for the Silencer). That’s for Silencers made out of metal, if you go to elastic/adaptive/ameba type Silencers you can go the other way around (fun for both, Bullet & Silencer). So, it's your call now, ...

Not for a debate nor another mess but just to clarify; both statements from Bendersquint are wrong: Sound propagation thru solids is a fact since sound is just a mechanical wave. Second, there is no lack on internal volume with thicker walls as far as you have bigger ID’s. And both are real life fac...

Re: Wall Thickness Relevance

In general, the thicker the better (seriously, really …). That’s for sound suppression but not for accuracy: Even you are doing BR shooting, having a Suppressor is not equivalent to have a Bull Barrel. Harmonics and center of gravity are not the same having a Barrel with the total weight evenly dist...

Re: Engineering Study

Try & Error R&D is a lot cheaper for the Smaller size Markets; like Suppressors. All you have to do is figure out, build and try. Not for individuals in USA since you have to pay 200 dollars tax per build. However, it’s not impossible to fully and accurately simulate a Suppressed Gun Shot. It’s just...

Re: New .308 can to be built

Ported Stepped Cones are really good for Suppression. Accuracy (grouping) is not related to the Baffles (or its features) but to the change in Barrel harmonics due to extra weight at the Muzzle. This phenomenon exponentially grows with Barrel length. 8 inches is enough for .308 Can and 10 inches can...

Mechanical elongations (deformation) are exactly the same as long as thickness and materials are the same for in & on. Now, of course, with “in to” caps you can go thicker ergo you can go stronger.
