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.
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.

Now that's something pretty ! It's a good Reflection on you.
The only reason after 243 years the government now wants to disarm you is they intend to do something you would shoot them for!

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
Of all the things I've lost it's my mind I miss the most
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.

Don't it always seem to go, that you don't know what you got 'til it's gone?
This is one of my favorite threads.....next to the "builds".
I know that there is alot more out there that has not been posted.
Keep the pics coming guys!!!!
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 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.
