No More Solvent Traps

[Capt. Link.]

With the dwindling numbers of "kit" suppliers the window is open to inventive minds. While many feel they must follow the latest commercial baffle trend they are not always the most effective or simplest to make.

Finn type 1,2,3 slanted sidewall baffles still work extremely well and conserve material. Each of these can use a separate conical spacer forming a K type baffle that will work on any caliber depending on which baffle is chosen. All of them are easy to build even on a mini lathe.

A favorite baffle of mine was developed by H&K for the MP5SD. It uses square tubing inside a round tube. This baffle netted 33db in 9mm. Using the same design and dimensions a .22 large volume integral should net even more and allow simple barrel tension for match accuracy. Most of the work can be done with hand tools.

Threading pressure tubes and end caps have stopped many a project. Using uber thin tubes may make threading impossible.... Welding or simple bolts around the periphery worked well 40+ years ago and the decorative use of button head screws make for a unique look that one member has found out.

Don't discount the humble fender washer. It can be used as is or better with porting making them asymmetrical. You can also shape these into various shapes using hand tools.

Many baffles are not used anymore because of cost not performance. I want to see some other than cookie cutter clones again.

My point is without the kits this hobby is far from dead and homemade can be better than commercial.

I have never heard of the finn type 1,2,3. I tried a search to get the idea of what you are talking about but didnt find anything. Where could one find images of the different types?

The biggest leap in suppressor tech since WW2.

I've also noticed that over these past 6 months and especially since Oct, nearly everyone has gotten out of making/selling them, and US Customs has been seizing Caches within our Shores.

Are the threaded tubes and endcaps still available? Those are the items that are hardest for home builders to machine to close tolerances. The internals are pretty easy to simply press into shape. By hand or hydraulically.

Good ol' Mickey Finn, true genius. Tom Clancy fucked him pretty good with his book.

[Historian]

Ninoslavt, I am intrigued by your novel ( pun & no-pun intended) information:

" ... Good ol' Mickey Finn, true genius.
Tom Clancy fucked him pretty good with his book..."


Would you kindly expand on this as I never read Clancy's
novels, liked the movies though, especially Sir Sean Connery's
performance in "The Hunt For Red October'.

In olden times in Southie a 'Mickey Finn' was what was put
into drink in a barroom to incapacitate a victim for 'rolling'.
Not I surmise what your Clancy reference is about.

Best.

Tom Clancy » The Cardinal of the Kremlin ... "Mickey Finn. That's his real name. He does the design work for Qual-A-Tec, and I wouldn't use anybody else's silencer. It isn't like TV, Cap'n. For a silencer to work right, it has to be a small caliber, you have to use a subsonic round, and you have to have a sealed breech. And it ...

[alordnapa]

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 tough to ban fuel filters, 3d printers, tennis balls, potatoes etc.

Yep, that's it. After that, Mickey stopped doing suppressors and other cool things for a big boys.

[Capt. Link.]

Charles Albert Finn worked at Qual a Tec as did Doug Olsen with other talented people.
A Mickey Finn is a drink made with Chloral hydrate aka knock out drops, possibly the basis of Tom Clancy's character.

very inspiring Capt. would love to see some old-school innovative designs.

[YugoRPK]

I dont much bother with he pseudonyms. K baffles are still readily available from STC and theres still a crapload of 60 degree cone baffles available.

The ATF's hard on seems to be reserved for those sellers hawking them with drilling fixtures at the same time and they dont seem to like drill marks either. Other than that the market for cones and K baffles is still robust. Tubes and end caps are no problem

[Sgt.Mike]

did sombody mention HK 5 SD baffles???






more effective than one would think

A favorite baffle of mine was developed by H&K for the MP5SD. It uses square tubing inside a round tube. This baffle netted 33db in 9mm.

Yes a great baffle used in a variety of calibers.

When was the last time a slant baffle was seen on these pages or anything other than mostly cones. While the use of cones is possibly the best for rifle pressures, pistols and low pressure calibers like .22 rimfire can be effectively suppressed with simpler means.
A wonderful baffle known as the crimped cone ,developed by Qual a tec and used by AWC can be made with little machining. If you have the ability this baffle was developed further by Doug Olsen and is used by the military.
In this pic a crimped cone is mated w/ the type three Finn baffle. It is also reinforced w/ welding.

Lower left is the crimped cone.

This is the evolution of the crimped cone.

Much original work has been pioneered on these pages. Unique .22 mono-cores known as the 69 and the Pd have near 40 db suppression levels yet have never been duplicated. Its not that the inventors are genius level engineers its that they applied what they knew. Thank you Andy!
Developed here!

We now have tools like CAM and 3D printing to take us into this next century yet welded tech has not been fully exploited, the point is home invention is not dead.

Another slant design Which "could" be modified to the simple flat washer



While that is actually a monocore it does show how a series of fender washer could be used with just a little bit of welding .. after welding washers to flats then to end caps, bushing giudes coupled with reamers to ensure no baffle strikes located from end cap to muzzle attachment ID...

wih just a small bit of imaginaton a reflex could be applied furthering the can volume while redirecting gas through muzle thread backwards creating massive distruption and lessening availble volume without sacrifing length from muzzle to end of suppressor hence free real estate.

OR a simple washer based design



while i'm showing these is not to say that this is the only way if you have a lathe or the ability to cut K's or cone by all means do so. As they are more effective in quite a few peoples opinions. but in a haste / lack of skill, funds, or machinery given enough volume and stacks a washer could work may not be ideal but could work hopefully I'm in line with the Op's intent of the thread.

[Capt. Link.]

About a decade ago I saw a integral barrel made by I'm not sure ? for the 10-22. It had but 4 hemi shaped flat washers w/ a small hole next to the bore ( ( ( ( that helped cause turbulence. The baffles were held together with metal strap, much like Russian manufactured suppressors . The unit was a fly weight and the suppression superb. Simple works when the details are thought out !!

https://images.app.goo.gl/QYDN6ygmp19mXBRaA

The Flat washer is much maligned from the suppressors of the 1960's. They were heavy,large and needed to be cleaned often but the suppression was often good if you did not mind up to 40 washers of weight.I know a guy that made Mac-10 two stage suppressors from fender washers and star washers, not bad suppression and they hold up well mostly because zinc is resistant to the nitric acid found in smokeless powder and the star washers helped turbulence. These old school builds used baffle spacing often based upon the length of the bullet. 40 washers can be reduced to 4 with wide spacing if you either keep a large volume,create turbulence or both. You can honestly build a baffle stack using light metal and strapping aka Russian style with only hand tools.

Take a standard heavy duty washer bend it into a hemi shape then add a dimple on either side like you would a K baffle. You now have a highly effective baffle.
Know of a effective simple suppressor, share it.

Thank you, brother. I found this most interesting article on Qual-A-Tec by
Douglas Olsen*.

The story of an operator actually using the Hush-Puppy
in the field on the goose was also relayed by Major Dick Culver.

"... I recall a report from a SEAL who had the task to take out the “guard goose”
at a Village in Vietnam. He shot the goose twice with the Hush Puppy and only succeeded
in making the goose mad and very noisy.
Obviously, this lack of lethality led to the guns being left behind during “real” missions...."

So much for mythology.

Sgt. Mike's interesting picture of the slant-baffle suppressor
is low-tech-easy to emulate after some thought.

Metaphor:
slicing a Bratwurst at 45º angle parallel cuts using say
a DEWALT Metal Cutting Saw -14-Inch. 45º.

First of course a central hole is drilled into the 'sausage' before
slicing.

Similarly, spacers with 45º parallel slants are made by cutting a tube
with said saw, clamping it with a vise to keep it parallel
orientation while sliding forward in saw.

Then baffle/spacer stack pushed into tube
of any length. Voilà.

Kalashnikov-'Russian-Peasant" KISS solution.

[Sgt.Mike]

Skimming through the article Historian gave a link to, and within that article Mr. Olsen's referal to "Mob Six" and the s--t vs good s--t rang true through all the branchs. The other part of the article was the Crankshaft design which I had seen posted elsewhere
This one made by quicksilver




By the way Historian your discription is a method / way I had not thought of to do the slant washer design, probably more durable than sheetmetal ....

Even 44 Magnum will not do the job if the shot placement is poor.

[0101silent]

I like this. I want to make one. Advisable?.22? .45acp? .308?

I found a barrel blank to be good source of metal with a long straight hole for building a monocore. Green Mountain sells raw blanks up to 1.4" od. They also sell blanks that are turned concentric to the bore.

There are also 6" long muzzle brake blanks available that are completely solid similar to a fake suppressor.

I would use a lathe, but the above monocore could be carved out with a grinder. A threaded adapter and tube could be welded on. Drill rod can serve as an alignment rod.

[Historian]

101Silent, found most informative your source information:

" ... I found a barrel blank to be good source of metal

Green Mountain sells raw blanks up to 1.4" od.
They also sell blanks that are turned concentric to the bore."

Reverting to 'Kalashnikov Russian Peasant" KISS principle bypass
the complex crankshaft machining: machine one central tube and using the
excellent concentricity of the blank,and opening up first ⅓ as twist diffuser into main chamber.
Revisit the Walsh/(0r-never-submitted) patent(s) previously discussed.

For example emulating the stellar PTK concept of "BB gun" quiet .22, some back-of-the-envelope
fun metrics that could be considered range from 1.25" to 1.75" diameter Al tube, 8"-10" length [ yes,some will
cavil 'too big, too ....' ]. The volumes in these cases center around 16± cubic inches. With Don's fillers, well
who knows.

Mental-Metal Musings are fun, are they not.
Wonderful way to begin 2021.

Please keep us updated.

Ninoslavt, " ..Even 44 Magnum will not do the job if the shot placement is poor."

Right on!

A dear-departed 'knuckle=dragger' now guarding the entrance to
Valhalla told of using a 'commandeered' Hi Standard .22 with can
to Quackly-Quiet geese in a land far-far away.

Ah the lowly .22 in the stone steady hands of an operator.
