I think 1.5 x 9 is going to be a bit small. The Bowers Vers 458 is 1.75 x 11.25. That's >150% larger internal volume. As far as pressures, I wouldn't be too worried. I think the 458 chamber Pmax is something like 35k. That's nothing. Coupled with a large chamber and bore volume, your muzzle pressure...

Historian, I somehow knew the exact pic you linked, from "1950s Salesman station wagon", alone

How about making the tube a tad shorter?

The Leonidas, by Liberty, is what you want to search for.

There are sites that sell components called "solvent traps". You can buy these, to form 1, and design your own stack.

Surefire isn't selling you a tube. Not only would it be illegal, but it's part of a proprietary system.

304 and 316 always want to warp. You need to either design around it or compensate with weld fixtures and setups. If need be, I'll attach large Al blocks near the weld, to absorb heat. I always do a couple test pieces to ensure I have the setting correct. The fixture works perfectly. It took a coupl...

I do have a question for T-Rex that I think will also help the OP. How much did your 5.56 can move after welding? Did you have any noticeable distortion using your DIY positioner? Any lessons learned that you can share on the welding? While I'm sure the parts had some final settling, it was nothing...

I got the best chips from interior profiling and an, IIRC, SCLR insert. For the exterior, I do believe I have CNMG. My insert game isn't very strong, but I've found what seems to work and what doesn't. I have a good selection of inserts and bars, but have yet to spend a dime. I received a good deal ...

My SB 9A is from, IIRC, 1947. I was able to use carbide tooling and take quite generous cuts. It's a nice metal to work with, especially for being stainless.

Do you mean "Austenitic" ?

Austintic? You don't say

Since length trumps all, why not use a shorter barrel and reap the reward of fitting a longer suppressor? The 300blk was meant to run a pistol gas system w/ a shorter barrel. An 8" bbl, with an 8" suppressor, would net a <carbine length gun.

ECCO is correct that the baffle porting adds Mfr time. Being a home maker, I'm not too concerned w/ it. In reality, it added about 4min/baffle, to the entire process. I can say, however, it showed a noticeable drop in back-pressure, when compared to similar suppressors, w/o that feature. Typical 5.5...

Are you sure about this? Buddy of mine is test shooter for PPU and he is shooting them all the time from integrally suppressed MP5s. There's only a problem if you try to use lightweight subsonic bullets (less than 140 grains) Lighter bullets (we're talking 9mm projectiles, here) travel at a greater...

try giving your baffles a little more shoulder before the cone starts. Make that shoulder .060" thick, then cut the register .030" into that shoulder for the full .040" deep cone walls. Much less risk of burning away your skirt while trying to get enough heat into the distal cone for fusion. Yup. T...

Welcome Mattman. Great to see someone brave enough to copy my design :lol: A couple things: -Prints show all material thicknesses greater than I actually cut them. 17-4 is strong enough to go thinner. Especially, the farther from the muzzle you get. Don't be afraid to thin some baffles out. Also, yo...

. I have never chronographed 9mm before, so im really not sure what velocities to expect out of different lengths of barrel, but I can research it. http://www.ballisticsbytheinch.com/9luger.html You can always drill more holes after shooting it a bit. While this is an accurate statement, he's keepi...

I just gave you a long reply and the forum ate it. Here's a brief review: 1. Full Auto silencers have been made from 100% Aluminum for over 50 years. 2. Porting negates the need for a blast baffle. 3. Almost all, full size, 9mm silencers, made form a large Mfr, are going to have 8-12 baffles. Why? B...

It is basically the same as a reflex galvanized steel sheet would certainly not be afraid, there is a life much higher than aluminum, rather comparable to stainless steel. Rather, is it about whether this design will work well or something needs to be changed specifically for .223? The 762 with a h...

As 40 said, not a reflex.
You don't need 50mm, 38 is fine.
Galvanized won't last long. SS or Ti
Galvanized also won't kill anyone.

I have and I know others have. There's nothing that says you can't, and I have an approved form to make a silencer, is my reasoning.

OP, the meter you're using is incorrect and very far from the capabilities needed. If you were actually getting 80dB, you'd have the next generation silencer. Hell, anything below 110 would make you The Man, especially from a semi pistol. There are only 3 meters capable (that reach the min Std) of r...

I don't always clip the first (centerfire rifle), but I always do the last. Seriously consider Aluminum parts (SS or Ti for blast or first 2) It will drop both your weight and final cost. Aluminum is absolutely strong enough for 9mm. I have no experience with any of the solvent trap retailers as I m...

Asymmetrical should work great. I use a cutter equal to half the bore diameter and cut 100%, if not more, of the cutter diameter. Symmetrically clip the blast baffle or don't clip at all. So, what are you going to do about parts? I think I read that SDTA will cut you a tube at any length you want. W...

I'm not sure what DM was thinking, with regard to those baffles.
They look like Rusty's RSC, with the flat tab from a Surefire Ryder and w/o the Ryder's vented mid washer.

You could cut the entire top off and almost have an RSC.
I'd prefer 10 normal cones to 6 of those.
