Ti-Thirty Form 1

Decided to do my F1 .30 can in Ti and this is what i came up with:

Suppressor
Material: G5 Titanium G9 Tube And Aquamet 17, Aquamet 17 is 17-4 PH H1150
Length: 8.296
Weight: 15.75oz
Diameter: 1.496 "1.5 turned between centers"
Wall Thickness: 0.052
Baffles: 9 Ti - 1 Aquamet 17 "Blast Baffle"
Spacers: 3 Long 6 Short All Turned From Bar


Brake
Material: Aquamet 17
Length: 2.25
Diameter: 1.00-.75
Shoulder: 30* taper
Outside Threads: Double Start 10 Stub Acme
Internal Threads: 5/8-24


Welded the tube to my rear cap/blast chamber than pressed in my baffles was about 5 tons of pressure because I made the baffles and spacers a .002 press fit. Sacrificed one baffle by having to learn not to use a socket when pressing baffles into a tube. Made a tool out of brass and pressed the rest in trimmed tube pressed end cap in and welded it up. The brake liked to whoop my ass i kept thinking i was doing something wrong when the threads wouldn't well thread so id start over but like other things sometimes you gotta go deeper.. Ill post pics of the brake when the mill work is done had to send to a friend bc i don't have a mill. Anodized entire can in a 2 Liter bottle with TSP. Its a light purplish color plan on using duraheat or something to coat can and Caswell SS black for the brake. Made a simple chamber to weld the Ti in out of a old shipping container.

Was having a problem uploading video I'm very happy with it and think it'll sound even better once i have some porting on the brake. I'll try to get video where I'm not standing under a oak tree..

Looks great.

Nice job fabricating the purge chamber. It don't have to be all that fancy to work well.

Yea I didn't have the money to buy new gas lense and all that so I used what I had turned flow up and used a second line inside allowed chamber to fill for about five minutes and my buddy went to town.

Wow--nice! Thanks so much for posting. I've been thinking along nearly the same lines for a 6mm can I'm planning (welded "thin" wall grade 9 tube, press-fit cones and spacers, etc.), but I'm not a welder (though I can hack small stuff together with a flux wire feed) and I have to find someone who can help me with that step.

I have two questions:

...Welded the tube to my rear cap/blast chamber.
1. I didn't realize that 17-4 PH (Aquamet 17?) can be welded to a Ti tube. Is that what you did?

I won't have a brake and, as a plain screw-on can, I'm wrestling with the Ti to steel thread seizure issue.

2. So the baffles and spacers OD is .002" larger than the tube ID?

Thanks for your help. Your share here greatly reduces the risk in my project, I think!

Baffles are roughly .002 larger than ID of tube yes and pressed in. No didn't weld aquamet to Ti I only welded the end caps..

Fantastic job, Sounded nice was that FP loads / factory ammo 308?

Nice welding chamber, it is a nice option if one does not have large gas lens and or trailing sock.
What was the wall on spacers and baffles?

Thank you Gunny wall was .065 on the aquamet baffle and .060 on the Ti ones and .060 on spacers. The rounds were 300blk fp from a guy at the gun show.
