Here is some more info to go along with this post,

I am using these 2, magazine clamps to hold a Mercury recoil reducer and the other anti-vibration device,
I'll list the weights of everything, so there is more information to decide with etc.

https://www.ebay.com/itm/Tactical-Barrel-Ring-Scope-Sighting-Telescope-Clamp-Mount-Sight-Hunting-Holder/153042520000
This tube clamps weighs in at 464.9 grs = 30.12 grams,

This tube clamps weighs in at 784.2 grs = 50.81 grams
Note: I am using just the clamp part, with nothing else attached.

As for the anti vibration device, I am using a Mercury Recoil reducer that was a shotgun shell type,
https://www.ebay.com/itm/Mercury-Recoil-Suppressor-C-H-Research-5-Stock-Model-Unused/293032989737
I trimmed the excess material off, leaving just the mercury container,
which weighs in at 2797.5 grs = 181.27 grams

Using the lightest, above clamp with the Mercury reducer, so far, I found the best place,
is to clamp everything together, right under the air stripper of my Gauntlet shroud.

I am doing more testing via moving the clamp/weight forward/backward along the shroud,
of the QB-79 shroud.............

All my shooting test so far have been with normal 22 pellet weight,
starting at the 14 gr range and going to the heavy end,
at 40 yds.

"Or start a new thread in PCP? Knife "

IMHO
You can always update your OEM post, via stating, "New info" starts on page # 7, on post #127,
this way all the info is contained in 1 post, as finding anything on this site is a problem.

Michael,

Great discovery!  Thank you for sharing!

What is the model name of the dampener in your picture?

Thanks!

I have no idea Taso, I've had it squirreled away for over 26+ years. LOL


I'll give it a think once I get a good afternoon nap Carl. LOL

Hmmm, was I closest in the guessing thread??  
It maybe a similar approach to reducing harmonics in a crankshaft via a fluidampr harmonic balancer.

[Thane]

Reminds me of the old Formula One bean can in the front suspension to provide additional dampening.

Can't wait to try it!

Michael,

you asked new thread or continue the old.

Well, there are 3 long pages of announcements and chit chat until we get to today's awesome news.   

Suggestion:
Name your invention, and put it into a new thread. Give it a good start for the new comers of future years...

Here're a couple:
MAD device = Mike's Airgun Dampener device
Mike's BAD device = Mike's Barrel Accurizer Dampener device


I'm really looking forward to trying this out, Mike! THANK YOU for sharing your invention with us!

New thread and link it in the first post noting to go to the actual thread. Then add in it the early findings of the testers. Also maybe close this thread and again link the new thread in the last post. Just an idea.

[Taso1000]

Ok, until "where to ask questions" is decided I have questions.   lol 

Someone had previously mentioned mercury recoil reducers.  When I'm searching in Google for archery dampeners, the shotgun recoil reducers come up versus the limbsaver rubber type dampers.

Michael, would the mercury damper work the same as the oil and lead shot type?  I've not handled either.

I don't have a problem gluing pvc together and building an oil/shot device.  But, I'd like it to be semi attractive.  Don't get me wrong, I've always been function over form but if we can have both that would be great.

I did see some oil type reducers made with epoxied copper pipe.  I'd rather use lead free solder but that will create other issues from the heat and reaction with oil.  I think long term consistency, because copper is soft and malleable, is not possible.

I do like the idea of the damper surrounding the barrel versus hanging underneath or attached with scope type mounts.

Michael, do you also know if the position on the barrel and different sizes od damper make a noticable difference?  Is there an optimal spot like barrel mounted versus somewhere on the forend?

I apologize to everyone for so many questions but the gears in my brain are turning!   

Thanks,

Taso

Very close. This technology later became what we know as a shop dead blow hammer. the first ones has fluid plus shot in them. Now only the shot.


Perhaps this would indicate the need for a test with not fluid?

Taso, I may very well be wrong, but I would think the end of the barrel is where the heaviest vibrations are. Even in my very heavily warped carbon sleeved barrel.


As far as inventions go, I'm not by any means the inventor. I just took an old idea, made for archery and tried it on a gun barrel. LOL!


In today's Green/politically correct world, I don't even know if the mercury dampers are still being manufactured.


After all, Mercury is known to the State of California blah-blah-blah.


Their opinions are not well respected in Texas. LOL

[darkcharisma]

There are alot of peeps interested in this thread. If the modifying function is still available, I would put everything into the first post. I don't think it's there anymore. I am sure everyone got notified in this thread already.

Why not start a new one and have everyone post their test findings and setups there. A contest for the best looking or working dampener. That way if Travis and any other builders can show their products . We'll get in contact and go from there.   Two birds with one stone

Mike's BAD device = Mike's Barrel Accurizer Dampener device


Matthias

Barrel Accurizer Damper Airgun Shot Stabilizer (I think you will get the acronym)


I built a coaxial version of this that threads to the muzzle but I simply don't have any bad shooting bullets to try!


I also discovered that the CF Tubing I used is not impervious to oil permeation (it leaks through the CF)

Yeah, I'd have to see how the mercury is sealed in.  If it's container is welded to my satisfaction I would keep it.  You don't want mercury contacting your skin.

I'd rather have the oil and lead shot but if the mercury recoil reducers work, it seems they are easier to obtain and a little more streamlined, for lack of a better word.  ¯\_(ツ)_/¯

Thanks,

Cancer is known to cause the state of California...

We played with mercury a lot as kids. We all seem to be kinda sorta ok, well except the odd twitches. LOL

Thurmond, it took me a minute. Man, that cracked me up.


My mentor in the Knife World made a knife he carried for a lot of years. It was inscribed Bad Bob's. LOL


Kinda seems fitting.

I glazed over his post and had to go back and see why nicely done.

Thurmond,

What about silicone oil or possible thicker silicone grease?

I am also curious if there is enough movement and impacts of the lead shot to break up into small pieces?  I doubt it since lead is so malleable.  There's also Hevi-shot that's denser and non toxic.
