[CAUT] Upright geometry problem (Nordiska)

Assuming even centers friction... you can get plenty even enough by 
feel.  But if you want to get really into it, there are several types of 
gauges available to measure this kind of thing.

I generally pull the spring well back and check the damper center by 
feel to see its in the ball park, no wobble but easy movement,  and then 
set dampers by feel. You could probably use a downweight measurer easily 
enough if you took the appropriate considerations to the rest of the action.

    I know how to reduce or increase the tension it is getting it even
    that I'm wondering about...some sort of gram gauge pulling on the
    damper?   Maybe it is simply trying to pull the spring towards you
    the same amount for each damper?
