Real hardness of springs

[Jeskai_the_Mighty]

Hi,

 

I found interesting article about real hardness of springs.

 

https://www.airsoftguns-europe.com/how-to-correctly-measure-the-real-stiffness-of-airsoft-springs

 

Someone read it? Or somebody tried to build this device?

 

Some exp with real hardness of Prometheus M210 in comparison with SHS M190?

Seems like a good idea, but you might want to move this to the technical or general part of the forum.

This area is for airsoft news, like new products and such.

Spring rating is pretty standard thing but Airsoft manufactures need to translate it in to terms players can understand i.e. An fps value but since that can be plus or minus 10% they tend to just aim for a certain fps then give it a made up m rating like m90 spring is about 320 fps or m100 is about 360

 

There's no need to go crazy measuring springs just stick with the same brand and fps increments will be fairly consistent

IIRC doesn't the number relate to the rough muzzle velocity in m/s? Eg an M90 spring should give you roughly 90 m/s (300fs)

Spring rating is not pretty standard. That's the point of the article. That m100 means 360fps is a standard you've made up for yourself. M100 means the manufacturer thinks it will shoot 100m/s with 0,20, nothing else.

 

It's a big issue for high end tuners. We try to stick to specific brands and then learn the individual springs in that brand, but ultimately it's a bad solution. We really should be using a Kg (at compressed state, 60mm ish) rating on packagings instead.

You missed the meaning of his comment. "Spring rating is pretty standard thing"  means exactly what you said later, as "there's an industrial standard for springs rating". But you cannot use it for airsoft as it will mean nothing for 99% of players. 

 

M1x0 type of thing, while clearly far from ideal, is much more meaningful for the common folk.
