Anyone come up with a spring yet?


Im thinking about experimenting - http://www.mcmaster.com/#compression...prings/=a9oaze
Id like to have a spring to go from tho and fine tune it from there

Why not just go with a 2nd gen. lift pump and regulater and adjust it from there?

 

I had thought about finding a spring to put in the 2nd gen pump to get 15psi. This way you don't need an extra item, regulator, to mess with or go bad.

I think you will want a spring with a spring rate of about 25 lbs/in.

I put a 2nd gen spring in my press on a scale and it took ~60lbs to compress an inch. And i'm told that a 2nd gen pump will make 45psi if it is dead headed.

This is from memory earlier this year, so the information contained may or may not be completely accurate.
