Anybody have information about air gun spring design ? a source on the internet ? library books ? i am not even sure i am asking the right question .
Thanks

Not sure what kind of info you are looking for BB Pelletier from PA has a number of spring related blogs/articles

The best are always chrome silicone , they hold set and don’t were out (as fast). A good spring does not loose power over time after initial set. That is a poor heat treating or material..(HATSAN is famous). Lately HW QUALITY HAS WENT WAY DOWN , got to save money some how.. I have looked into getting them made but there is always a minimum order and it’s now quite expensive..
I pity the industry when Macarri or Vortek goes away.. Macarri isnt the type to share his information and unless somebody buys the business and kisses the ground he walks on. ..after market springs are dead..
There are some Uk makers but they are mostly 12 ft lb springs. Titan makes some good springs but limited to sizes..
if I was all you all ,I’d stock up.

I think i will need a cheap china springer to experiment with , to see if my idea might work . AN adjustable power springer . but i am also thinking someone has tried this idea and found it not adjustable enough to be worth the trouble or cost ?

Spring knowledge is not what many think.. everyone thinks bigger wire,more coils = more power
Take a 34 coil factory R9 spring. The load rate changes after you clip a coil. All Things being equal power will drop around 8 to 10 fps.. YET ,THE SPRING IS MAKING MORE POWER AS THE LOAD NOW IS ACROSS 33 coils.
Clip another two coils off , keeping all things the same and watch it go down 20 fts. Still a stronger spring
Now add back the same spacing as the three coils and your going to see power go back to what it was originally or better with a more controlled deader shot cycle..
This is a simple example.. wire diameter and coil distance rate are factors as well
I’m running a .125 wire x30 coils in my R9 and getting a fantastic shot cycle. At 17.5 ft lbs. just a snug guide and new VAC SEAL…. SAME WIRE SIZE AS FACTORY ..smaller diameter spring and less coils. But much more powerful and controlling.

Rather than make an adjustable spring has there ever been an experiment with a dual set trigger sear. Essentially creating an option to cock the rifle to the first sear engagementfor low/medium power, or push say an inch further on the cocking stroke to engage the second with max compression and power. So not so much adjustable. But dual velocity. Could also potentially be a dual notched piston and a single sear
