HW 95 - where to get the correct OEM spring?

[robs5230]

Been trying to source OEM HW95 springs for years (since 2009 actually), but it seems like when I buy OEM HW95 springs I get the HW97-HW77 springs.

The specs I find in the mainspring data thread says the 95 spring should measure around 13,8mm ID with 3,1mm wire,
and the 97-77 spring should measure around 14,3 ID with 3,1mm wire: https://www.airgunbbs.com/showthread...ng-data-thread
I've bought both 95 and 77-97 springs from both Versandhaus and Knibbs over the years, and they have all been the 14,3 ID spring.

My 95's all came at German or Swedish power levels, so I dont have any original full power springs for them.
The full power (Norwegian power levels) old HW85 came with the 13,8mm ID spring, and I'd like to get the same spring for the 95's.

Doe anyone know a source for the 13,8mm ID HW spring?

Pretty sure this is the nearest you'll get. The ID can be a little variable, between 13.6 and 13.8.
I run this spring in my 99
https://www.versandhaus-schneider.de...oducts_id/1502
Also pretty sure that they are the spring that UK 77/97 are (or were) supplied with.
We don't get the 77/97 14.3 ID, 3.1 wire spring here

Can you say length and rate of the OEM spring you prefer please?

I really dont know!

What I do know is that the OEM FAC 13,8mm ID 3,1mm wire spring does a great job in the HW85, and I'd like to get more similar springs.

Titan no.10?

Titan no.10?

The #10 has a 14.8mm ID, that is a mm larger than what I'm looking for.

After looking at spring dimensions, it seems like the titan #8 might be the spring closest to the one I'm after....

Thanks! It makes sense from manufacturing standpoint to use the same spring.

Versandhaus lists their spring as 13,6mm:

So maybe worth another try? I'm just afraid they'll send me the 14,3mm spring that I already have a couple too many of..

Currently we cannot deliver to your country of destination.

When i looked last week bro

Was sending to my UK Address

Try one of welsh willys new HP Dagda springs, might well be close to your needs , may not be on his site yet ??? but are available , you'd have to talk to him, didn't realise you were in Oslo

Dimensions are as follows
34.5 coils
280 mm length
Wire Gauge 3.00 mm
O/D 19.60 +/- mm
I/D 13.6 mm

USA HW95L, 2018 year factory spring = 34 coils & 11.375” long. Spring ID = 14 mm, 0.5512”, as near as I can measure. ARH has kits with springs if this will help.

Thanks. I'm currently using ARHs QX4600 spring in the 95 with good results. Has to be spaced up for a balanced shotcycle in the full stroke 95.
His Hornet closed coil spring is also good for a high power FAC setup, but I want to reduce power a bit from that level.

What I want to try is a 13.6-7mm ID spring with 3,0mm diameter wire and enough coils for good preload without spacing.

Welsh willy HP Dagda and Titan XS #8 seem to be the closest ones on the market.

HW95K .22 with an ARH kit, Vortek seal, GPL-205 lube at 17 FPE. Cocking cycle is silent until trigger latch. About 9K shots after install and very accurate.

I had the utter pleasure of having a go with a couple of Vortek kitted HWs yesterday and they shot extremely nicely. As you say, the cocking action was very, very smooth, too. Impressive.

A Titan #8 just came in the mail, and a trial fit on a old OEM HW plastic rear guide shows that it is a tight fit, just like expected.
I might have to shave a few hundreds of a mm from the guide, but if the spring works as I hope, the original guide plus a tophat is all that is needed for a nice setup in the 95.

[TonyL]

Sounding promising.

Similarly, I'd heard it said previously that Tony Wall at SFS had his springs made to match the OE Weihrauch guide. So just a top hat required. We once stripped an SFS tuned '95 at a Bash as it had gone running slightly over. And, indeed, the standard HW guide fitted the spring very nicely and top hat present. The rifle shot very nicely indeed.

Quoting myself... because, yes the three OEM HW spring guides I have enters the spring snugly, but entering them fully will not happen without shaving the guide a bit. The guides are tapered from ca 13,4mm to ca 13,8mm, and the spring seems to be around 13,3-13,4mm.
So the OEM guide has to be turned down a few tenths of a mm.

Very useful information there, evert; thank you once again. And, again, an issue for those of us without lathes and not being able to do the necessary work.
