Re: Need To Critique This Design

I agree w/ the Capt. Also, I wouldn't cut the blast spacer as you have. Ports near the distal side, to vent into the coaxial volume, would be more adequate and help protect the outer tube. Try to incorporate indexing clips, to help align the baffle clipping and coaxial vanes. Personally, I'd increas...

I'm guessing your can is a hybrid design that features baffles w/ a end wipe and not built like the WOX-1's stack ?

I'd say you're right. I'm just wiped at the exit, not throughout.

Wipes cause much inaccuracy plus you will need a FFL to replace them.
I can't agree with this part.
My 4.5" AR15/22, can hit 3.5" swingers @100yds, from a wiped can.

Also, the end user can legally replace wipes. ATF has never reversed this decision.

Re: R8 my 3D printed Form1 design

Why build something that's easily machined? Why are you using plastics? Need to be overly thick, wasting crucial volume. Always clip baffles. IMHO, it's a waste of a stamp. You're not doing anything that hasn't been done, it won't be an optimal design for 22lr, and it won't last as long as tradition...

Re: .22 rimfire, integral vs add-a-can

If you're going to do a 10/22, just do a really good muzzle can, that you could swap between hosts. The action of the 10/22 doesn't let you get to hollywood quiet. If you wanted to do a bolt gun, go integral, all day long. My integral 22 is a Savage MKII w/ an ~8" monocore. It falls into the stupid ...

Re: What would cause inaccuracy when hot?

I'd say that was more luck than anything. I would never go less than .040" diametral clearance, usually run .050"-.060". No suppression is gained by going tighter, just the potential for issues like the OP's. I didn't chose that bore arbitrarily, it was a decision based on previous results. If deal...

Not sure of OP's design, but I've done 9mm K's (what the OP is using) w/ a bore of ~.386. That's only 16thou clearance, per side. No issues w/ accuracy and marginal POI shift.

Re: .308, 18" barel uncorking pressure,

Your numbers are a bit off, but not terribly. Barrel length needs to have the "chamber" subtracted. Use cartridge overall length, minus bullet length, and subtract this from barrel length. Use that as bore volume. Use QL's "Useable Case Capacity" as your constant for pMax (62kpsi) volume. Also, your...

You don't usually bevel thin walled tube, it's just butt welded. But, stick welding w/ an oversized rod, a bevel on both pieces (#3) should do. You can turn afterwards, to remove the buildup.

Re: What Is Maximum PSI In .22 Rimfire Can?

As Ecco pointed out, the volume of the system (chamber, barrel, suppressor) is exponentially greater than the chamber itself. Suppressors aren't sealed vessels and don't warrant the same engineering/design.

Well, sort of. Technically, it's a silencer as soon as you bore the end cap and assemble that onto the tube. But that doesn't mean it's illegal for the F1 maker to manufacture the rest of the parts. Exactly, a tube with a bored cap would meet the definition. I didn't say it would be illegal to make...

Re: Form 1 design for an FN1900 in .32 ACP

A lot of your design features are ancient. Drop the perforated blast baffle. A single port is all that's needed. Ditch the mousehole (the cut at the cone's base). As said, blast spacer is huge. I'd probably put the first baffle 1/4" from muzzle. Personally, 'd just fill the volume with cones, but K'...

Re: tons of junk coming from suppressor into pistol action

The spring in your gun, not the booster. The booster spring works in conjunction w/ the suppressor weight. The pistol's recoil spring will delay the action's unlock time.

I was interested in pics for, above all things, an idea of baffle geometry and their direct impact w/ back pressure.
