Supressor Baffle Pics!

Yes, it can be legal to make a silencer. For everything Form-1, from silencer designs that are easily made, to filing forms with the BATF, to 3D modeling. Remember, you must have an approved BATF Form-1 to make a silencer. All NFA laws apply.

The spanner holes were cut for the GemTech Trinity tool but the AAC tool offers ALOT more grip than the flimsy piece of scrap that GemTech sells and the AAC tool happened to fit.

Why reinvent the wheel?

AAC PILOT: We took this one apart for a customer and made a new endcap for it. Now he can clean the thing.

AAC Aviator: This is our shop demo that we have had for a few years. This will have both front a rear endcap replacements. I am ordering a broach for a hex front endcap.

There should be 2 in there, I know I uploaded a couple, I know on another site when they were posted they magically disappeared.

They are a variant of the cone but not smooth or steps.

I saw one of them taken from the outside. The design looks pretty cool.

I wonder why they didn't press those.

Does titanium lend itself well to forming? I bet not.

No it does not form well, you can't get their design with forming either, needs to be cut.

When I worked in the Aircraft industry we pressed losts of Ti components, just needed lots of pressure, over bend and good tooling

eg Al was 1-2 deg o/bend, stainless was about7 deg and Ti 15 deg

I was told it was too brittle to bend and retain its form and strength! What grade were you bending?

That was a few years ago now I can't remember the exact grades to be honest and I know there were a few different grades used

The other thing to remember is that with many metals that we formed they would go through heat treatment, to soften, to bend then heat treatment again to bring the strength back. Typically we treated in salt baths to control temperatures.

So I guess yes you can form parts from Ti but maybe it would be too expensive at least for commercial cans - Aircraft parts, as you can imagine are not known to be cheap

When I was in aerospace we bent and formed a lot of 6AL4V sheet titanium.

It was generally annealed dead soft, then hot formed with a LOT of pressure.
One part was about 3"x7"x.125.and the press used was 10,000 tons at 1400 degrees F.

This was to put a 30" or so radius along the 7" dim, and a .125 curved joggle across the 3" end.

Very tough stuff to work with, but in this application, an F18 fairing segment, one end of the part is at room temp, and the other at about 800 degrees F, with supersonic aerodynamic loads, all in a saltwater environment.

Edited for typing error.
Don't it always seem to go, that you don't know what you got 'til it's gone?

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.

Those are Surefire baffles, which are coincidentally the same as Ops inc(really close).

I totally forgot about that picture!

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 Cans with some minor mods. For the .22LR, they are the basis for the Turbine Baffles (P.P.).

My comment was based on what the designer and manufacturer of that silencer explained the reasoning for the flutes.

No doubts about your source of information but cooling are a matter of heat transfer and exchange and that’s related to materials, their temperature and they heat absorption properties (briefly). Material shapes are less than 1% impact. Many people make artifacts that fly and still don’t know why. That’s pure try & error approach. Anyway, these are great Baffles and that’s what counts, my hat off to the Designer. Looks like we need a thread to debate about “why/how stuff works” instead of “what stuff work”, I’m just saying.
