Re: Form 1 Typo
Shoot, I'd get a different piece of tubing for a spacer; the thickness of that thing is ridiculous. You're adding a bunch of unnecessary weight and eating up volume that could be helping reduce noise.

Re: Screw it... I'll make my own.
No quench needed either, but otherwise yes. The H900 condition is achieved by starting with annealed 17-4, holding at 900* F for 1 hour, then air cool. That's it. Hardness should be 42-44 Rc. The H900 condition actually machines really well but is harder to drill, so I prefer to make the baffles bef...

Re: Screw it... I'll make my own.
Since it's taking so damn long to get back ATF Forms anyway... I'm seriously considering just building my own can on a Form-1. Looking for a set of SIMPLE (first build) plans for a SHORT, direct-thread 5.56 can, for a 7.5" barrel... I'm actually a Mechanical/Aeronautical Engineer by education,...

Re: thread pitch
I wouldn't do 15/16" x whatever. I would do whatever decimal amount gives you full thread engagement with maximized tube thickness. This. There's no reason to stick with a specific fractional size. I would do 28tpi for even more remaining tube thickness; the only advantage to a coarser pitch i...

Pitting sounds more like corrosion, but I didn't see it.
Still, that's a rifle round. This thread is about a 22 LR suppressor.

Re: Tube erosion?
I will only run one 17-4 baffle...the blast baffle...to keep weight down. However I could visualize the deflection from the blast face directly impinging on the aluminum tube and wondered if anyone here had seen significant erosion on high round count cans from this. It would be reduced, but still ...

Re: Tube erosion?
Just anodize the tube, it'll be fine. BTDT. It's just a .22 LR after all. You sure don't need 17-4 for the baffles either.
I've noticed lately here people worry way too much about erosion and longevity of low pressure cans like .22 LR and 9mm.

Re: Max suppressor weight for recoil booster
Isn't it better to over build? No, not to the level you are taking it. You can achieve pretty much infinite durability at about 1/4 the weight of what you're planning. There's a lot more to it than just lifting weights. For example, with that lead anchor of a pistol can, all that extra weight will ...

With a 40 oz pistol can, whether it cycles or not is the least of your worries. That weight is ridiculous, and about 4x more than a "middle of the road" commercial or form 1 can. This doesn't even fit the category of erring on the side of durability "cause it's a lifetime purchase!&qu...

I am certainly no engineer. I am. I appreciate your observations and thought provoking comments.

Re: Secondary Blast Baffle discussion
Still, a can with several 1/8" spacers that could allow the baffle spacing to be rearranged would be cool for testing this. That's how I built my first F1 can (except with 1/4" and 1/2" spacers), for exactly that reason. All the same parts went in the suppressor each time, but they c...

T-Rex, gotcha. You are correct of course that 17-4 is more free machining in the hardened states. I really like 17-4 partly for it's strength. In a F1 can I built several years ago, I'm using .030" thick cone baffles in 17-4 (blast baffle is .060" thick) for everything up to and including ...

Re: Is a blast chamber really needed/heat treating baffles
17-4 is not free machining. At best, H1150 rates at a 50. Cutting the annealed condition is less than optimal and H900 is worse. While less hard as annealed or H900, H1150 cuts decent and will do a fine job being internals. It will have corrosion resistance equal to 304, but have twice the UTS. I a...
