dome/ellipse baffles ?
dome/ellipse baffles ?
I've read some old post that reference dome or ellipse baffles, and them having certain specific attributes or uses. Just wondering what those might be.

Re: dome/ellipse baffles ?
Was it LavaRed's parabolic baffles you're referring to? He never really spelled those out it seems. Said they were a bit impractical, but very quiet when perfectly set up or something.

Actually, more like this from Wicked:

I seem to remember reading a a reply to a thread here where someone mentioned 'round/dome/bowl/hemispherical/etc' baffles had a unique set of properties or something. Can't find it now.

Ah yes, that's the build I was going to search for next, should you say the LavaRed build wasn't it. A lovely piece of work, that. Very nice execution and I think a solid acoustical principle, in that a curving surface is likely to render more destructive interference, breaking down vibrations before they exit the can, than relatively simple cones.

Re: dome/ellipse baffles ?
I have lost the original post I was speaking of. I am still interested if anyone has any knowledge of round baffles, domes, ellipses having any special characteristics that aid suppression when used as baffles.
Re: dome/ellipse baffles ?
I'll throw my .02 cents in the ring for what it's worth. My 'dome baffle' can was built over 5 years ago, a first attempt at building a F1 suppressor. So far as I know, there isn't anything magical about the baffles or their shape. They are very effective in a high pressure rifle can with a small bore. Not nearly so much in a low pressure application with a larger bore.
The real reason I used the 'dome' baffle shape? Because Ops, Inc. and the Ops 'inspired' SureFire cans used them. They were/are top performers. So did the Russians, abet in a very different back-to-back layout. I'm not a designer or engineer, so I didn't see the need to re-invent the wheel. I don't completely understand WHY they work, just that they DO. I liked many elements of the AAC layout, so I combined all three into one Ops/SF/AAC bastard design. I did not show every feature of the build, there are a few things that aren't in the pics, but the basic design is sound IF you have the ability to form the baffles and weld them together. More people probably don't use this type of baffle because they can't form them, not because they don't work.
Partly I did it because I could. My strengths are in tooling, machining and welding. The baffles were difficult to form without a die set and press. The cost would have been foolish to get half a dozen baffles that way. Metal spinning was the answer. Could something similar be constructed by other methods? Certainly. None will be cheap or easy. But the performance is there; a dome baffle works very well in that specific application. Proof is in the pudding. This can was mil-spec tested and documented @ -33 to -37db reduction in front of reps from SAS, Gemtech, Liberty and Huntertown Arms.
