HW77 buzz

[Petey]

My pair of Diana 34s had a MINUTE amount of twang when new, but have settled in to a solid thump now with zero twang. There is absolutely no way I could deal with the twang thing. Would be a shame to HAVE to open up a new high end gun to tame the twang. Probably end up buying a used 30 that has already been kitted. Thanks again for all the replies.

Just drop in a tune kit and enjoy the thing . Really----- it's no biggie. You'll be happy you did...... Or just send it to me--- I could use a 77.

As nced said, a tight fitting spring guide cures the vast majority of spring twang. You might research the 'heat shrink tune' method of gluing a bit of heat shrink tubing to the spring guide to take up the slack and reduce the amount of space between guide and ID of the spring. This is cheap and functional. But since the thing has to be disassembled to do it anyway, might as well put in a longer lived spring and a tight guide with some good lube and be done with it for 20k or so rounds.

 The heat shrink method works great. Had to do it on my 350 magnum with a Titan spring installed.

I used aluminum foil tape on the guide and tophat on my 07 Gamo Big Cat. JM spring, seal, lubes and a plastic sleeve around the spring. Awesome difference, and no problems after thousands of rounds. she's a quiet, smooth, hard hitting tack driver. But for the Fraulein, Id recommend a PG2 from Vortec. Really sweetend up my HW95.

Really mind boggling that the manufacturers of high end air guns don't have them mechanically sound when they leave the factory... Basically, they furnish a VERY good barrel and receiver that have to be "worked on" to get their full potential. It couldn't cost the manufacturers THAT much extra $ to get it right, out of the box.

Sad truth is THEY DON'T ....
Reality is if you want it smooth as whats possible ya got little choice but to go in and make it right !

Personally, I prefer a solid build with steel guides, even with some twang.  Plastic breaks.  Seen many posts about broken guides in a lot of guns...

I've READ about "plastic" guides breaking when fitted tightly in heavy wire springs, however after several decades of my TIGHT FITTING Delrin or molly filled nylon guides used with springs of .120-.128 wire I've never had a failure! 

No real issue with metal guides except (as you alluded to) tight fitting "plastic" guides do a better job of dampening twang, plus a plastic guide won't wear the inside of the spring coils like a tight fitting metal guide unless it's a softer material like brass or bearing bronze. LOL.....a fitted metal guide does work better than a sloppy fitting factory "plastic" guide and whatever works best for you is the best guide material to use!

Actually, I haven't found that spring twang is much of an issue except for the fact that it's annoying to this shooter!

That's an odd statement! LOL Not much of an issue, but annoying. Annoying MAKES IT AN ISSUE!  heh heh.

Seriously,  SOME twang? Can you elaborate as to why you like some twang? I like that solid "thump" that my Diana 34s produce.

Because that is usually the trade- factory steel guides i a gun with twang, or custom fitted delrin or maybe some other type of plastic.  Most of the posts I have seen about broken guides are either RWS or Gamo guns.  I am not insinuating that the build quality is the same between the two, but pretty much all the threads I have seen regarding broken spring guides are RWS or Gamo guns.  And I think neither are delrin, I have only seen good things posted of custom fitted delrin guides so that might be moot.

Was biting my tongue not saying anything ... being the rabbits loose 
Indeed some of the CAST / INJECTION molded guides simply snap/break.  Cheap acts as cheap is 
Delrin/Acetal guides are a whole lot tougher and when properly manufactured & fitted seldom if ever will suffer a failure IMO.

Thanks for holding back, Scott.  Truth be told, i've posted some awfully foolish things and I have some pretty thick skin- fire at will, lol.  If i'm wrong I'll come around.

"Annoying MAKES IT AN ISSUE!"
Well...."annoying" in the sense of "sound". If the twang affected my accuracy then it would be more than annoying, however I haven't found that twang affects my accuracy at all, it's simply annoying to the point that I take the time to "kill it".

Twang doesn't seem to bother some shooters and at a DIFTA field target match a fellow brought his FWB300 just for kicks. Ya know what, I could hear that match springer twang from 10 feet away yet it was still a "driver of SMALL head tacks".....just a little weak for FT!

LOL....make more sense now?

I bought one new in ...2009? It was made in 2005. It never had that kind of buzz! Sounds like you have NO grease on the spring!  I think I shot about half a tin before I put in a JM kit as that was the plan from the get go. The Hw77/97 guns and the R1s are easy to do as you don't really need a spring compressor to take them apart. Get the Vortek kit or the JM kit and you will be happy. The Vortek is a true drop in.
