22 Lgu -spring diddlings.
« on: December 17, 2016, 04:45:11 PM »


  The lgu in question had a standard spring and the tp opened to 3.2mm,4.9mm of preload and shoots in the very low 10s with superdomes and tops out at around 10.4 ish with aa fields. It's favourite garden pellets are hobbies which it shoots at 620fps -10.1. I'd say the original spring which is short but stiff ,could do with an extra coil.
 So tried a longer softer hw spring which fits the guides perfect.
The hw spring is a standard spare hw item which has shot maybe 15 ,000 ,still straight as a die with no kinks or faults.It came out of hw22 95 some time ago.

  So comparing springs, hw is thinner wire ,much less pitch and 22mm longer.
 Now shooting softer but generally making +1ftlb across the board. More testing to follow.

Have you ever thought about tinkering with co2 pistols? My idea was to get a battery powerd lock de-icer, take the heating element and stick it to the co2 cart, there will be a contact switch so as soon as you pick up the pistol the heating element switches on and warms the cart, I have been told that it would be better to heat the valve block.
This should make fast firing better as the co2 cart won't freeze up as quick and help the co2 evaporate, preventing snow from the barrel as well as giving a better shot count.

Sounds good nick,the Walther springs have been good so far & work well in some others,the Century spring is a bit stiffer though.I like longer softer springs overall in fact i've i got a couple recently from Wonkey to try in a 99s & 95 when i get round to it.

Have you got the measurements of the LGU spring ? I'll compare it to the smaller cal version. :)

Nutty-no i've as yet not owned anything co2 apart from a soda syphon some years ago.

 This might throw some light on the job Mick.



 When I first got the walther it was abit underpowered but shot beautifully.I've had it some while ago shooting well over 11ftlb with differing lubes and various preload but it rankled me.
 So now it's shooting in the mid 11s with just a hint of tinbum paste on the seal and piston tail and bearing rings. Not used it enough to be seriously worth checking consistency as such but it's less than 10fps at the moment with all pellets used.

I had a good session with it this afternoon, no vibes or twang, it definitely shoots softer , still relatively easy to shoot with minimal poi from different positions.  It'll take a few sessions to really say anything conclusive on that front though.

Nice one,like i mentioned before my LGU is still standard & has no faults but i'm still tempted to alter it a bit.I'm sure it should be a bit tamer but i am supposed to be leaving it long term to compare later .

I think in there natural state they can be abit sharp,they're reputedly supposed to have a very quick lock time. Have you any notions as to what power your's is producing?

 You might want to keep an eye on the trigger adjustment screws, on this example and others I've read about, the threads are abit baggy and the screws can wonder in or out. Abit of soft Loctite cured it.
 
 I fitted in the dummy moderator ,wadding and baffles, it's quite effective.
