Titan XS no7 spring for a HW95?

[Mark A]

I am going to be buying another HW95 in .22 from Germany soon and just looking into which spring to buy to bring it up to around 10-11ft/lb. I know the Titan XS no8 is supposed to be for the HW95, but I believe these springs usually need shortening. Looking at the spring chart for the Titan the no7 looks to be the same wire size and has the same ID and OD, its just a bit shorter. Would it be possible to use the No7 and not have the hassle of shortening the spring, or is it too short? I could always use delrin washers to adjust the preload if needs be.

I might also be adding a Tinbum short stroke spacer to the piston if that makes any difference.

Size of the springs according to the chart are:


No7 - 30 coils - 255mm length - 3.3mm thickness - 13.8mm ID - 20mm OD
No8 - 34 coils - 295mm length - 3.3mm thickness - 13.8mm ID - 20mm OD

Thanks

It may/may not help but a couple I've measured give No 7 42 lb/inch rate and No 8 40 lb/inch
The No 1 is larger OD but sits between the other two, at 275 mm and 40 lb/inch rate, as does the No 9 but softer at 35 lb/inch which could be interesting.
What bore/stroke is the 95??

I'd have thought someone would have known the answer to this with all the shed tuners on here..

I guess I also need to measure the original spring guide to choose the best fitting ID spring. On my other HW95 I bought a WW kit that was utter garbage and I ended up sanding down the original spring guide to fit the Titan spring that came with the kit. So maybe one of the springs with a slightly larger ID would be ideal.

You should prob start by getting the correct spring then get guides sized to that really which is what welsh willy kits are cant understand whats garbage about that.

The fact the gun twanged the same as it did originally is what was garbage about it. Plus the spring ends were just left with grinding marks. Overall it was a big disappointment for £60 and left me wishing i'd have added the extra £20 for a Vmach kit. Even after sending the guide back for a replacement at my cost I just got another loose fitting guide that still twanged.

So this time I am planning on just buying the Titan spring and sanding the original guide again as it worked well last time.

Every single gun is different, that's why some kits are over powered, some under. I beleive starting with a spring known to need shortening is your best bet. Nothing ruins a gun like dead preload added to a weak spring! Start high and slowly reduce your spring until you get the power you want.

That makes sense, i'll go for the No8 then to be on the safe side. Thanks.

It would appear that it is just a shorter version, but whether it will be right is another matter.

I have two HW80's in .22. Outwardly they appear the same, internally they have both been treated the same and have new seals along with 15mm short stroke extensions and they both produce roughly 11-11.2 fpe. They both have shortened genuine Hw export springs, one with four coils removed, the other with six?!
