Progress update. Tube, end cap, and muzzle cap close to finish. All made from Ti-64 (grade 5).




End cap with counter bore spanner wrench holes.




End cap lip is beveled to give smooth appearance.






Muzzle cap needs to be cut down yet (red marker).





Stamping will go toward the muzzle, and 3 more machined flats will be added.

That looks awesome. Makes me a want a lathe in the worst way.

I know this has probably been asked a dozen times, but what size VSR's are people ordering for the baffles in a D-Cell tube?

Pardon me, but what/who is this DM I keep hearing about?  Feel free to shoot me a message if a link constitutes advertising.

Anyone know if DM or anyone else does custom end cap work? I wanna do something....... Different

Yes.  He is doing mine for a Bowers versadapt insert.  I just had to mail him one to measure.

Does anyone have the FP/VR compendium from the nuked thread?

Going for the light-weight, all Ti build next.

Pretty sure he'll do whatever he can within reason.

I know mine are different than most, with recesses for the Saker wrenches instead of AR armorer's wrench. Also custom outer width and thread length. He's also made every one of mine with the exact OD as each tube.

You know the barrel bushing on a 1911? Yeah, I want a raised piece just like that machined on the end cap. The exit hole will be where the barrel would be on a 1911

 

IM this way too please

Are you guys figuring in your muzzle device with the cost of the can or strictly just the can?

I think I might just ditch the YHM muzzle device idea and go with Griffin mounts. From what I'm reading the Griffin mounts are pretty good in the sense the don't shoot lose, lock up nice and solid, and after doing the math the cost difference won't really matter much to me for the 2-4 rifles I will be putting them on.

You're welcome. ;-)

I'm not, because all of my ARs already had them. I have two YHM cans and two Sakers with YHM MAAD mounts. That's why I'm building most of my F1 cans with YHM adapters.

I know it's a horrible reason but I hate the way YHM's mounts look. I just wish there was a way to make an F1 can with an AAC ratcheting mount.....not saying it's the best but I already have 2.


Does anyone know what PSI a tube such as DM's can take? I wasn't sure if a 338 can would be possible? The larger DM tube diameter is 1.625" and  Silencerco's Harvester Big Bore is somewhere near 1.8". I wasn't sure if there was a reason for the 338 cans to be larger since max psi for 308 is 62k and 338 is 60k.

You're not alone in that thought. They don't bother me. Plus, when my next 3 F1 cans are approved, I'll have a can for every AR. So, you won't see the muzzle devices very often.  

I could've just gone direct thread if I'd known I would end up with this many cans, but with the YHM mounts and adapters I can swap between hosts to see how they perform.

I'll delete if in wrong area but are there mounts available for form 1 suppressors in order to use the specwar ASR mounts?

That's actually not a bad point. My 2 f1's with my existing cans would be even with the number of AR's I have. So, I too wouldn't need to look at the ugly mounts. I just need to make sure I don't buy any more guns.......

Good luck with that...  At one point I said why would I ever need more than 4 cans? I have a .308, a 556, a 22, a .45, I'm covered for life.

None that I've ever seen. None of the mounts that require moving parts are as easy for machinists or individuals to make. That's why the YHM, Griffin and SDTA muzzle brakes and/or flash hiders work so well...no moving parts on the can itself.


At that point, you could go direct thread for the rest of them if you're going to dedicate a can to a rifle.

Thanks. Was trying to brainstorm a 30 cal one using those mounts and then a 9mm that used a griffin 3 lug mount possibly.

I'm guessing you mean mounts to use on the Specwar Trifecta flash hiders and brakes?   I was considering this as well, and from my limited research thought about using the Omega ASR mount on the rear of a Form 1 can and also the Omega end cap on the front of the Form 1 can, may work??
SilencerCo Omega Accessories
Omega ASR Mount

why can't we use these?

If Liberty suppressors HATE ring is the same TPI as their booster then yes you could use SICO mounts.

Don't know if there's any legal reason.

Just won't find off-the-shelf threaded tubes for them. It would be an even more custom job.

Similar to if somebody bought an Omega and a flat cap. They could have the ASR mount and brake for an F1 can if you went the custom route...unless there's some legal reason you can't.

They would still be 1.5", right? Just need someone to cut the correct threads?

It's not the OD of the suppressor that's important...you'd need to know the ID of the Omega (or OD of the ends).

And the two ends may not be the same thread pitch...but I don't have one to check.

Is it easier to worry about/mic the ID of the omega or take measurements directly from the mount?

If you can indeed use some available tubes, cutting threads can't be terribly expensive.
It would be cool but I think SDTA brakes and adaptors make much more financial sense

I'm getting down to go-time. Three are engraved (filed 2/15), and the other three (filed 2/23) should be done early next week. I'm expecting the first stamps in the next 6-8 days, and the next ones a week or so after that. Cerakote was ordered today. Three will be Tungsten Gray, three will be Burnt Bronze. Late April should be a fun time.

Does anyone know if a tube thickness of .12 in grade 9 titanium will handle supersonic 308? Mjollnir was nice enough to let me know his specs.

I searched around and most of the threads i found on various websites seemed to be speculative at best. I imagine it would have no issues with 300 subs but I want it to be capable of standard 308.

I guess if the spacing material is tight enough you would really be able to account for more thickness.

0.06"

(Don't forget to divide by 2)

darn auto correct...

I feel stupid.......

If it is in fact .12 (versus .06), then yes. Plenty of tubes in the .065 range out there being used on rifles from what I have read. But I'm not an engineer, its at your own risk, yada yada yada

Don't forget...

There is a 0.035" thick titanium tube insert as spacer for the blast chamber and throughout the tube as spacer for my VSRs. Even though pressure can leach between the tube and the VSRs, it should provide some shielding to the outer tube from the blast.

The lateral forces on the baffles and end caps should (will? I'm not a mechanical engineer...) be far greater than the forces of the blast against the walls.
