HW97K twang?

[Oldgringo]

My new 97K was shot a few times with various pellets and then was taken apart cleaned an lubed (although it wasn't need).  Put back together, she's still a bit twangy.  What is this plastic spacer from a coke bottle thinghy I've read about?  Does it go around the spring guide inside the spring or what?  A picture would be helpfull so that I could try this remediation before shelling out a c-note for either a Vortek or JM kit.

Greg,
get some one local to make a fitted spring guide replacing the factory garbage under size guide .... on that rifle IMO don't screw around with getto type mods, do it right and do it once

That's exactly right.... Absolutely no need for a "kit" your spring is fine, turn a new tight fitting guide & tophat & you'll have no twang.... Also don't use any tar! It's a brandade for poor quality loose guides.... None of my springers have a drop of tar in them & none have twang either

I strongly recommend polishing both ends of the spring with wet or dry sandpaper on a flat under water.  It goes pretty quickly with 150 grit.  You may then move to finer grits if you wish.  Finish the job with a bit of good quality lube on each end of the spring so it can spin freely.  I did this to two guns and needed no new guides.  The twang was gone.

 Can guides, top hats and such be done on something like this. http://www.harborfreight.com/7-inch-x-10-inch-precision-mini-lathe-93212.html

Certainly but your MUCH better off buying an old US made lathe..... Another major thing to consider is tooling..... Even the bare min is expensive if bought new....

Bottom line is you are MUCH better off buying a good used lathe that includes tooling. Unlike a new Chicom set up it will hold its value & even a well worn one will last a hobbyist a life time. Take your time, shop around & you'll find a deal.

Around here, a machine shop will not hardly talk to you for a C-note. So unless you have a friend that has a lathe and owes you a favor.... buy a kit. I have saved enough for a 97, still working on enough for a professional tune. It is a shame that we spend that much on a rifle and have to work on it as soon as we get it. Add on a new scope/mounts.... our hobby is not cheap.

Another tip concerning spring noise on the 97.

The ball securing the cocking arm in position also has a spring behind it. If you close the cocking arm you can hear it zzziiinnnngggg along.
Remedy: set the rifle upright; pull the cocking arm back from its closed position; press the ball down with one finger; let a drop of engine oil flow between the ball and the cocking arm; close up the cocking arm; problem solved.

Thanks everybody,

I did polish the ends of the spring and otherwise lubed her per the '2lbtrigger' video.  I wouldn't start to know where to get a new guide turned, certainly not locally. 

Inasmuch as there has been less than a tin through her thus far, I think I'll just shoot her some more and see if she quietens down a bit.  If not, I can buy a half dozen kits for the price of the Chicom lathe above.

Thanks again, y'all.

You might consider using a TinBum Tuning Kit . Just need to check your spring's inside diameter for correct fit. These are custom delrin guide kits.

I second this!  I put one in my TX 200 from him and it is great.  He is very nice to work with also.  My new HW97K is twanging also!  Just as soon as I can tear mine down and measure the inside of the spring I am going to order one from him!

Thank you, Josan. 

That certainly quieted her down more than a little bit plus it made the overall cocking operation easier.  I'm gleefully on the way to resolving any spring/guide fit issue.

I was annoyed by this noise for more than a year  when some guy on a dutch airgun forum presented me this solution.
Isn't it great how we can help each other with an ocean in between?

Yes it is.  As a matter of fact, my HW97K came from The Netherlands.
