: Question on filling the stock with foam or any other materiall??
: pedroeguiguren July 04, 2009, 10:07:54 AM
I´ve read a lot of threads where people fill the stock of their gamo whisper to reduce the spring twang..
I will like to know how to take the butpad apart and how to fill it and with what??
If any whisper owner has already done this and felt an upgrade and a reduction on the spring twang without "secondary effects" let me know hot to do it with some pictures if posible.

thanks in advance!

Remove the two screw's that hold the butt pad on, it should be hollow inside the cheek rest area. A few of us use memory foam to fill that void in there, check your local mattress outlet. They usually have remnants of that foam around and cut you a deal on some. The memory foam cut's down the overall vibration from the stock. the spring will still do it's vibration thing but the foam help's to dampen it as it passes through the stock. Ed

I took the action out of my recently moved to a new home Daisy 1000 and drilled a hole into the stock. Then I used that spray in expandable foam to fill the void. Careful, it grows pretty fast but at least you can cut it with a knife when it gets hard. It sounded a whole lot better than before when it sounded like someone ran into the side of a van carrying pots and pans.

Cost me $4.00 for the can of foam.

If you have a paper shredder like I do to get rid of all
the junkmail, just use the shredded paper to stuff the
buttstock.

You can really pack it in there and it will really insulate the
hollow sound and remove the twang. Compacted paper also
has some weight on it and your Whisper will feel more balance.
The recoiling spring will have material that absorbs its force.

Plus you are recycling for the sake of our environment.

I used a bag of blue ice - the stuff you ise instead of ice.   I found that if I stuffed it into the but and tapped on the muzzle, it sucked it right into the stock. Works great.

Fisherdude, after you did the BlueIce thing, how was the balance affedcted?  That stuff is heavy compared to paper--

Just be careful what you put in the Whisper stock. The forward end is open into the trigger area. Things like spray foam, or even shredded paper could wind up in the trigger mechinisum.

If you want to add weight to realy soak up recoil and noise, and improve your hold like a target rifle, put a chunk of foam rubber in first to close off the front of the stock to the trigger area. Then experiment with quantities of  bird shot well mixed into modelling clay, or the duct seal some buy in the home centers to use in their pellet traps.  You can get inexpensive modeling clay at any art store, or art department of Wal-Mart. and work it into the stock.

Thanks for that-- was going to look and see if the stock was "open" up front.

Now I know!

After installing an air venturi  gas spring, I wanted to  test recoil dampening by adding  bird shot.

When I found the front of the butt  was open I stuffed a couple of paper towels in and rammed 'em home with a wooden dowel. Then I filled the stock full with number 9 shot. Gun weighed over 12 pounds which is as high as my postal scale reads, but sure was steady to shoot and hardly any recoil.

After about 25 shots I'd heard what I thought was a piece of spent pellet bouncing back and hitting the table.

Next shot.... same thing. And the shot after same, but I saw it just in time to see  a #9 pellet roll off the edge of the table.

Even with all that weight dampening the recoil, pellets were working past the wadded paper towels and dropping out through the back of trigger opening in the stock. Figured test time was over rather than risk a pellet getting into the trigger guts. Don't want to mess up my  CDT trigger.

DON'T WORRY MY FRIEND:


 AFTER READ THIS THREAD... I PUT INSIDE THE STOCK OF MY WHISPER VH A SMALL T-SHIRT OF ONE OF MY LITTLE GIRLS, BUT

THERE WAS MORE SPACE AVAILABLE.... SO I STOCK AN UNDERWARE TO FILL THE REMAINING SPACE.

   **THE CLOTH... REALLY WORKS.    I KNEW ABOUT THE UGLY TWANG SOUND BUT I DO NOT KNEW ABOUT

THIS EMPTY SPACE.  THE NOISE HAVE BEING KILLED!!!!

I used a piece of paper towel to fill the hole in the action end of my Gamo stock, then used spray foam from the butt end. After it was dry I trimmed the excess and replaced the butt pad.
On another rifle I removed the butt plate and stuffed the stock with some pink fiberglass insulation I had left over. Packed it in good with a large diameter dowel so the stuff was like a rock inside the stock.

I wonder WHY the Gamo engineering/manufacturing staff does not address this?  Seems like a small cost to do a factory solution that would result in a LOT of increased customer satisfaction/better performance.

You have a good point Fuller but Gamo and many other air gun manufacturers never really fine tune any of there products. That is for us to do..:) But if you want quality in a synthetic stock then I would suggest the FX Cyclone Synthetic PCP..:) They are only around $1395.00 and believe me the stock is high end and high quality..:) At that price it should be..:)

I have stuffed all my synthetic Gamo stocks with shredded up memory foam. When packed in the stock and compressed it makes for a solid stock. I have heard of guys packing socks, underware, shirts and even clay...:)

Sorry if this is a dup-- Thought I sent it already.

That price is a bit out of the reach of this "OlTimer" !!!!  I would whittle me one first!  

BTW, on the subject of stocks and vibration, is there such a thing as re- bedding used or done any of the modern airguns?

Gene:  PM on another subjectsent.
