My e-Form1 was approved the end of Dec... 4 months and 3 days after I submitted it. The tube is 1" OD .070" wall titanium and the K-baffles are 416 SS from surplus target barrel stubs. I decided to make the first K with a deepened recess for extra expansion, and the last K has an undersized cone diameter to fit inside the end cap. As shown in the pics, the mount has 8 scallops and 12 inner holes for weight reduction, and the end cap hole in coned inside. I used a 59/64" 8-flute reamer to open the tube ID to .922" to allow my K's OD at .920". It weighs 6.2 oz, the OAL is exactly 6.0" and finished in KG GunKote FDE applied with an airbrush and baked-on. I've tested it, but don't have a video or db levels to report... I believe it is comparable to most commercial demo videos I've seen though.
What do you think???

Re: First Form 1 project: Ti/SS 22 can
Looks like you did a great job.
I don't see why it shouldn't offer good db reduction.

Re: First Form 1 project: Ti/SS 22 can
Thanks for the feedback... A friend steered me to this forum about 6 months ago, and I learned a lot of excellent information from it. Another detail about my build is that I held the reamer about .4" short of the mount end to form a shoulder for the first baffle position. I also improvised tools for the mount and end cap install/removal, shown below. I also included a pic of it attached to my primary host pistol.

Re: First Form 1 project: Ti/SS 22 can
It is a nice build and the photos are great.I like the end cap mod first I've seen like that.Your paint job looks flawless. The use of a internal shoulder is always a good idea as even the pros make mistakes on the effect of forward thrust.I think every one want's to see a bunch of holes in paper or a dead rabbit along with a range report from you.
Glad you are starting to make your presence known and contributing to this page.

Re: First Form 1 project: Ti/SS 22 can
I really like it.
Where did you find a P229 Elite in .22? I didn't know such an animal existed.

Re: First Form 1 project: Ti/SS 22 can
It's actually a P229 Scorpion originally shipped with a 40S&W barrel/slide. I bought Sig's conversion kit in .22lr with the threaded barrel option. I also have their 357Sig barrel that drops right in the 40 slide for some extra power. For those not familiar with that cartridge, a 125gr bullet at 1,350 fps (standard ballistics) has 505 ft-lb energy, compared to a 45ACP +P 230gr bullet at 985 fps that produces 495 ft-lb energy (both measured at 15 ft).
Thanks again for the positive feedback... I'll have to take it to the range for some testing demos.

Re: First Form 1 project: Ti/SS 22 can
I have P229's in .40, .357SIG, & 9mm. After thinking about that I checked their website & they do make a factory .22. Interesting.
Also like how you made the cap to accept a bushing wrench. I'd have never thought to do that.

Re: First Form 1 project: Ti/SS 22 can
So is your rear cap wrench cast to fit your cap? Is that cerrosafe or what is the material?1rflman wrote:Thanks for the feedback...

Kinda looks like cast iron.....you have easy access to a foundry?

Looks more like a thermoplastic to me. With a knurled metal ring to contain it.

Re: First Form 1 project: Ti/SS 22 can
Hadn't thought about plastic....maybe JB Weld
Thought it looked a lot like raw cast iron casting that had be bead blasted......but that would be rare to have access to that....plastic/epoxy is more likely.

Re: First Form 1 project: Ti/SS 22 can
The mount end removal tool is a plastic pill bottle cap filled with Marine-Tex epoxy. I sprayed the mount with release agent, and after the epoxy had about 15 minutes to "set", I pressed the mount in it to form the impression. After it was fully cured, I faced it off in my lathe to the contour in the pic... Basically an economical design. For the end cap tool, I just drilled two .092" holes properly spaced in the polymer bushing wrench and pressed the 3/32" pins into it, that fit the 7/64" holes in the cap.
Re: First Form 1 project: Ti/SS 22 can
I use that style on all my rifle barrel muzzles. It's a 30* bevel to a 90* crown, with a chamfered bore-to-crown junction. Here are some pics of an example on my Ruger 10-22:Capt. Link. wrote:...I like the end cap mod first I've seen like that...

The temp was about 30* when I went to the range yesterday, and I made "a bunch of holes in paper", but no dead rabbits. Some pics below of the results. I held the bolt closed on the 10-22 for target #2, which affected my hold on the rifle and the resulting group size.
It looks like the suppressor changed the point of impact slightly to the right, less than 1 MOA.

Re: First Form 1 project: Ti/SS 22 can
No dead rabbit required it's just me and my jovial spirit. I like the Frenching detail on the barrel I'm guessing fine glass bead. Perhaps you might explain the how to on viewtopic.php?f=10&t=115318 and add to the library of information.A shift of POI to the right and down is common as is enhanced accuracy.The combat crown looks good but I was talking about this end cap.Have you put in for stamp #2 yet .

Re: First Form 1 project: Ti/SS 22 can
I made that end cap mount with the interior radial holes for weight reduction, and with the thought it could increase turbulence there, but figured it wouldn't hurt anything either. My #2 stamp was approved in Jan., which is for a 30 cal can still on the drawing board. My design includes the Saker 51T QD mount and a 1.625" titanium tube. I'm researching the mount thread specs and dimensions I'll need to fabricate the "coupler"/blast chamber I will be making from 17-4 SS to attach the tube.
I call the barrel finish "frosted diamonds", but your reference to French (lace) sounds good too, like the stockings.
I'll try to come up with some pics and tips for a how-to instruction guide. It is bead-blasted with 280/320 fine glass beads over a plastic mesh barrel shipping protector.
Thanks again!
