Re: No More Solvent Traps

The suppliers of "Solvent Traps" will just have to rename the units into something more politically acceptable under the new administration. Perhsp they can be recategorized a "Transgender marijuana Vaping chambers" or something they will like better? I would imagine that its going to be pretty toug...

Re: Don Walsh On Mesh In Suppressor Design

It did not look like a real dissertation to me. I just did a preliminary check to see if the school existed, if the author had any history of a Doctorate granted, etc. Just basic Google-fu stuff. It was an interesting paper, but it looked a lot like the outlines that people sell as "dissertation or ...

It is interesting. The "Defence College of Management and Technology" was not established until 2009, and the "Cranfield University" does not seem to have a department by that name.

Re: Suppressor design for maximum recoil reduction.

How would using a pendulum to demonstrate decreased recoil distinguish between the effects of the mass of the suppressor and the delayed gas pulse? I don't doubt your word on this, I just can't think of a definitive way to measure it. Recoil ( like noise suppression) is so very subjective.

Re: Suppressor design for maximum recoil reduction.

I don't suppose you could get away with putting ports in the suppressor tube? Is there a weight limitation in your service rifle rules? Without any ports, I don't see how you are going to get any recoil reduction other than from the additional mass of the muzzle device. Am I missing something?

Re: “Solvent traps”

I think it is pretty evident that even an untrained monkey can make a serviceable, but perhaps not great, suppressor from a Solvent Trap ( They are not suppressor "kits" because that might demonstrate the intent to manufacture a suppressor, or worse, constructive possession, and that...would be naug...

Re: Useful Small Lath Tool

I tried using a Boring bar adapter on my mini-lathe for this purpose, and it works. Kind of. If you actually want to hang a drill, a reasonably long shaft and chuck, a longer and more robust would probably be better. The poor little QC mount is not made to carry a large off-axis weight like a power ...

Re: Hi Standard

I would venture to say that for any given suppressor volume, a wet, wiped , copper/bronze/silver screened device will be significantly quieter than a "conventional" can. Admittedly, these need frequent repacking, but the OSS probably did not have to shoot a heck of a lot of people. For a given volu...

Re: Need To Critique This Design

The volume of the helical portion of this design is pretty low; I have a hunch that it would not help much, but that's just a WAG. Maybe our computer modeling guru on the board can do the math?

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

I don't see any posts by CMV about how this design worked out for him. It is a pretty high weight-to-volume design, so I really wonder how it worked out in either of these builds.

Re: What would cause inaccuracy when hot?

Are you using cast slugs? The additional back-pressure caused by the can may be causing your barrel to overheat, and this could cause erratic performance. Even without cast slugs, an over-heated barrel will cause accuracy problems.

Re: tons of junk coming from suppressor into pistol action

Increased back-pressure is an inescapable side effect of adding a suppressor ( There are some manufacturers that say otherwise, but I think they are Commies...) Effectively, your action is opening too soon, and the gas pressure is causing that mess flying back into your face and dirtying up your gun...
