[CAUT] Which side to yank the butterfly spring?

Hi Ed.

I've heard this that and the other from a host of places when it comes 
down. Like most subject matter there are a lot of approaches that will 
work fine and there are things that are not so good.. The basic idea 
here is to tighten or weaken the coil one way or the other.  If one 
sticks to the core of any given problem one easily enough finds a more 
then acceptable method.

In the end, which side of the lever you pull the spring out can only 
make a difference if one side or the other fits you personally better.  
IMHO that is :)

Cheers

    I'm reconditioning a set of wippens, and have them off the stack. As
    I was cleaning gunk out of the rep lever groove and cleaning the
    spring tip, I looked under the lever, at the allignment of the
    spring coil, and it occured to me that when the spring is snapped
    out of the groove and over to the bass side of the lever, the coil
    can open easily when you yank on the tip of the spring to make it
    stronger. Snap it out to the treble side and it jams against the
    underside of the rep lever when you pull.

    It seems to me this would be a good policy - snap the spring out to
    the bass side when adjusting spring tension.

    I don't recall reading or being taught to do it this way. Have I
    missed something, or am I imagining that something insignificant
    really matters?
