I was just wondering how my new Mendoza spring might perform (compared to the old one). I got numbers in the 125-150 pound range, which intuitively sounds "right," so the program must be working at airgun scale. _________________ ¡Listo! ¡Apunte! ¡Fuego!   Posted: Mon Feb 02, 2009 12:08 am kanyon Silver Status Member Joined: 09 Aug 2008 Posts: 1582 Location: New Zealand Slavia wrote: kanyon - thanks for posting!

The trick is to remeber the compressed length is the piston stroke\plus pre load compression. EG---- piston stroke - 75mm Pre load ------ 25mm total ----------- 100mm As the pre load is pre stored energy before cocking. B11 spring came out at - Rate - 45.03lbs / 7936.81newtons/metre - per inch of compression. total force at compressed length - 151.75lbs / 679.39newtons   Posted: Wed Feb 11, 2009 8:37 pm sniper Silver Status Member Joined: 28 Nov 2008 Posts: 3752 Location: Star, Idaho i know when the post is from kanyon before i see the author. i think i can read the accent. _________________ I believe in gun control, If there's a gun around I want to be controlling it.......
