Weihrauch HW35 | Main spring change

I've got some a replacement top hat and spring guide for the Titan XS mainspring.
It's a simple enough process to dismantle the HW35 and swap parts over.
it still let's go with a wallop and crack like a rimfire but will see if the performance is improved when over the chrono

The HW35 is a great air rifle, way better than the most modern crap. Why change what is good. I own almost all HW springer models and the 35 is one of my favorites, specially for hunting. Cheers!

People say the 35s are best at around 10.5 ft/lb and more power ruins the shot, thats true on the early 35s but later one's can be tuned to 14ft/lb and in 22 they shoot great at that, mines doing 14ft using FTTs, dont try it on the older ones with the larger transfer port, 4mm l think, later one's are 2.8mm.

The stock is a beautiful colour. Seems accurate and if it feels smoother, job done! Great video.

Very interesting video well done with the logic I’ve been there many times with the variables it’s a constant work and labour of Love but at best a mental stimulating ideology that’s what makes us doo stuff and intelligence you have in these trials enjoyed much.

i've just put a spring in mine and it has 26 coils a tinbun top hat and guide the coil diameter was 3.5mm , it does have quite a bit of preload approx 2.5 inches which isn't easy to install as i used a large sash clamp and had to mark where the threads off the cylinder and end cap 1st mesh to make life easier. then i put them both in the sash clamp pushed the end cap until it stopped , then started to turn the end-cap with a large spanner as a lever in the trigger orifice whilst at the same time keeping the pressure on by turning the sash clamp vice, its took a few attempts but yo must be patient and wear gloves, but it would be easier if you had and extra pair of hands for that bit. mines now stop on on power just under the 12 ftlbs it was only doing 9.5-10 ftlbs on its old spring. i didn't have to squash any coils. 26 full coils goes in lovely and there's just enough room for one 3mm power washer if need be ?
