Break Barrel Vibration Dampening

[SkwirrelBeware]

I grew up playing tennis. Late 80s, "vibration dampeners" hit the market. Basically nice Rubber bands that slid between strings, and truly absorbed vibration after hitting the ball.

I've wrapped a piece of rehabilitation/exercise band around the barrel, mid-way, 5-7 laps with a basic square not. Trying to absorb vibration.

Is this theory snake oil or does it even have the slightest bit of validity?

Trying to squeeze every bit of accuracy I can from this $100 break barrel, which I really like, after I made the trigger adjustment. 



Thank you all in advance.

I think something with more weight would be better but I don’t know For sure. I was a machinist and back when I was an apprentice one time I seen my boss wrap a clump of putty around a boring bar to keep the vibration down because it was chattering a little bit and it worked.

A guy gave me his Diana 34 break barrel to look at cause he can't get it to shoot good. I may try a barrel dampener. Amazon has them for 9.99.

i haven't even looked at it yet. He said he tried a few different types of pellets. I just joined & am new to this forum. I like it. Looks very informative.

Might want to bore scope that gun if you cant get it to shoot well. Try a few pellets first but those little 34s are usually pretty accurate. If it's not accurate chances are it's the barrel or a bad seal. Do the tissue test first thing..... Just trying to save you some time here. I have alot of time and frustration into springers lol.

Going to bore scope it & try the tissue test. Thank you Raden1942. I'll report back but might be a few days. Too many irons in the fire.

try soft bedding the action in the stock. https://www.gatewaytoairguns.org/GTA/index.php?topic=66631.0





also some wieght in the stock will help

 

[gambleone]

I will try that. Thank you for the great info.

I ordered 1/8" neoprene from Amazon. Going to give it a try.

I have a Lyman bore scope and will not fit a .177. Barrel was very dirty. Got a lot of lead out. Back scope screws were a little loose. Front stock screws were loose. Removed stock, cleaned and oiled. I'll have to wait till tue when it warms up a bit to try it out now. I did order some 1/8" neoprene to bed it. Thanks to all . Great forum here.

Take it apart and fabricate a shim that goes around the spring. Make it either out of a smooth plastic soda bottle or a piece of metal shim stock.

I have done this on a number of spring guns with full success on all.

Neoprene working great. Thanks for the info.

Synthetic stocks tend to be hollow and amplify the vibrations, especially in your ear and cheek. Got PA pellet foam? Take the butt pad off, cut some of that PA foam into chunks and jam pack that stock as full of it as you can.
Simple teardown, clean up and lube tune will also help since factory lubes aren't that great and rifles either have too much or too little.

 

[gambleone]

Going to try that. Thanks much.

Neoprene working great. Thanks for the info.

Is the soft bedding working still?

 

[gambleone]

Seems like it is. Shooting well.

So I am fairly new to air rifles. I have alot of experience with fire arms. My brother gave me a cheapo air gun crosman optimus and when shooting I noticed how much it jumped and vibrated when shot. So I took the spring out degreased with engine degreaser. Then sanded it with a dremel using the maroon scuff pad. Decreased it agian. Washed it under warm water using a clean toothbrush and let it air dry in front of a fan. After that I sprayed rust-oleum undercoating pro grade rubberized spray. I put about 5 coats on it and let it dry for a day or 2. It should be a built up layer of coats letting it dry pretty well between coats. It fit into the piston very smoothly but the spring guide that's on the inside of the spring was quite tight so I saned the inside of the spring so it fit in smoothly. Then I spread a good coating of white lithium grease on the spring, on the inside of the piston, and on the spring guide ( do not put the lithium grease on the outside of the piston and on the piston seal). Mine gun is a synthetic seal so I used a small amount of synthetic oil on a q tip and spread it on the seal and on the outside of the piston keeping the face of the seal clean. Then I put it back together and it seemed to dampen the spring very well. Reduced recoil and made it more accurate. I do not have a chronograph so i dont know how it fast its shooting but it seems to be normal speed. The first few pumps were alittle hard but after that grease got worked in it cocks way more smoothly than it did before. I've put about 50 shots through it so far and it seems to be holding up I'm not sure how long the coating will last but wear and tear is inevitable with any fire arm. Also I redid the finish and made custom grips. Please be safe when working with fire arms. I advise anyone to become educated before doing any work on a fire arm. They are dangerous.

Break barrel-barrel vibration dampening or barrel tuning is a slippery slope. It can potentially gain every last bit of accuracy possible or turn what was a decent shooter into a wild mess. I've dabbled a little with barrel tuners on springers, not enough to be "experienced" but enough to see positive effects on one gun and one pellet combo... And two instances where those AG's were better off without messing with the barrels harmonics.

 

[Kliney85]

I agree on barrel damping. Some guns it works on others it doesn't. I think on fluted barrels it is not necessary. The fluting makes it more rigid damping the barrel already.

I have to wonder about the value in barrel dampening on springers. Are we talking about barrel harmonics or vibrations. Bang for the buck dampening the spring vibrations does more IMO. Top hat and delrin spring guides if possible, and as another member said plastic bottle wrapped around the spring, does more for shootability IME.

 

[Kliney85]

I was talking about dampening the vibration of the spring not the barrel I left the barrel alone. I don't see any reason to mess with the barrel. I just sprayed the spring with a thick coating of truck undercarriage rubberized spray and greased it up real good. It definitely tamed the spring vibration. Compared to what it was before it's definitely better. It cocks way easier there's no crunching or popping or anything when you cock it. It's pretty much silent when you shoot it. I think it worked well. I just put a new scope on and added a bipod. Did some work to the trigger. I put about 50 rounds through it so far. Took it apart and it seemed good. I'm gonna shoot 50 more rounds and take it apart and see how that coating is holding up.
