Re: First range report on my Form1 build.

What the hell? That's exactly the wrong thing to do. Amazing. ACROSS THE FACE of the entry point of the cone, not parallel to the boreline. Was I unclear?

Re: First range report on my Form1 build.

Looking at the site selling various cone spacers, it seems for the most part that they have enough thickness to allow cutting some clips without opening out the hole diameter. I'd drill a hole in a scrap of wood the same diameter as the front of the cone and set the cone into that, holding it there ...

Re: First range report on my Form1 build.

Even washers can benefit from some 'clipping' as in bending them on a shaped anvil with a punch. One side or two. Redirecting gas/pressure flow is essential if you're after suppression better than what you seem to be suggesting with "could definitely tell" kind of equivocation. Either it's...

Re: Smart phones and their sound level apps.

Yes, tried a few apps, on a few different smartphone models/brands. None has been capable of metering even the noise level of a relatively quiet airgun accurately, and certainly not a firearm. Jesse James infamously boasted of an 88dB reading for 5.56 through his sweet potato suppressor, which is ri...

With only 1 post it seems likely you're spamming for your product. But in this case I think it's actually cool spam.

Re: Removing lead fouling from aluminum bells

Doesn't seem very thick, so probably not affecting suppressor air volume significantly. It's ugly, but you don't have to look at it in use. If it were mine, I'd coat all the fouled surfaces with lithium grease and shoot it. Suppression improves slightly (though with a bit of smoke), and the white li...

Are you trying to get it clean for some reason or simply removing buildup to allow reassembly with most of the grime out of the way? If you are trying to get it clean what is the upside compared to just getting it sort of clean? This is an important point. It's hard to remove the base filth from al...

Sure. They'll probably go that way with it if they can find a couple of witnesses to confirm Chauvin's animosity. I don't care much at this point. It's all become such a mess, so many hurt and dead as a result of the rioting, so many businesses destroyed. What a waste.

A well thought out statement, and if it could work that would be wonderful. Unfortunately it seems unlikely to happen.

Hey, you don't need to sell me on the notion that police are corrupt.

Like I said, probably stupid. Gauges? I don't gotta use no stinkin' gauges! Tap and die man here, winging it on a tiny old TAIG. So far, so good, no baffle strikes (knock wood) and everything I shoot is politely quiet.

Being a guy who's never made a taper mount, but can appreciate the challenge of achieving concentricity with such a short part, I'd make the tube first, threading both ends. Then make the front cap and install that. Only then would I make the rear cap, turning OD then outside threads to fit the tube...

Re: Baffles or ???

Yeah, problem with really thin material is that it hits critically high temperature very quickly. So if what you're using it on tends to heat up a normal commercial suppressor quickly, it will likely bien through some sort of swarf packing in no time at all. Ultimate example - the finest grade steel...

Re: Baffles or ???

From what you're describing, it seems unlikely you have any experience with a suppressor. The pressure involved even with something as weak as subsonic .22lr is likely to pull a structure like that apart in short order.

The lathe swarf you're describing sounds basically like a coarser version of pot scrubbing material, the Chore Boy such as Dr Dater used to wrap around the reflex/ported area of the barrel on his integrally suppressed Ruger Mk pistol.

If it were an aluminum core it might be worth a few dB to spend some time with a Dremel or other tool to hollow out most of those voids, opening out more air volume. But with stainless... that would be a lot of work. Probably burn through a few Dremel tool motors getting the one job done. But hey, i...

Re: Beretta M71-my first threaded barreled firearm-what now..

Enough larger that you don't get baffle strikes but not so large that suppression isn't great. And even without impacting the baffles, surface effects are a thing. With a 1/4" hole accuracy can suffer due to pressure feeding back from baffles, depending on baffle shape and proximity of the bull...
