HW80 with hw97 spring?

[thomas9784]

Hi guys,
I wondered if anyone has tried a hw97 spring in an hw80. Ive just got one here and was curious to try (which I will) before I purchase anything else. adding or subtracting preload where needed.
Any thoughts on this?

I guess i will have to fit a thicker piston sleeve to take up the slack.

It can work but is a bit weedy for the piston weight. Guides either end are vital to kill twang as the fit is like a pencil in a dustbin.

Thanks mate, So its prob not ideal for the piston weight as it is. I was just thinking as its here and got my curiosity.

Give in to curiosity, always! Have a play with springs, preload, weight etc and you will learn the interaction between them. This is invaluable for future tinkering.

There is no such thing as a stupid idea.

Will my bic biro spring fit in an hw 30?!

I'm sure I read somewhere that one notable tuner used/or used to use HW77 springs in 80s.

Probably more fiddling involved to get to a desirable end point.

They can work just fine ,the guide is the same.If you have the nylon guide it might be a good fit as some arn't that bad.A sleeve will help & a top hat that fits.

Can be used when chopped in the 35 as well, similar to the 35 Vixen.

Just fitted a 20 mm dia. spring in place of a 23 mm, with nylon outer sleeve to pack the gap, 'cos that's what I was given.
Performed much better than original by my judgement and the owner is very happy. HW35

V-Mach have been doing it for years and now Weihrauch have done it for some time , you dont need the big spring to get 12 ft lbs.

Weihrauch don't, they still have a different spring for every gun. Buy one from the continent or a "grey" import and its fine, unfortunately many HC guns do come with a cut down 77 spring though, same as everything in life it must be more to cut costs than anything else as all they are known for now is the terrible twang.

For a long time all the new HW80 that i have worked on and that is a number of them have had the small diameter spring.

From memory I'm sure a Diana 34/52 Spring will also fit an 80's guide more snugly...the smaller outer diameter allows for the fitting of a piston sleeve, making it less twangy. I think the ID of a 97 Spring will be too narrow for the guide. I'm probably wrong on all of the above!!

The guides are the same, no problem swapping.
