Baldwin springs

My advice is to leave the arms of the spring in their original shape and
work near the coil, push upward while moving the tool slightly toward the
end of the spring, but always begin near the coil, that is where the spring
is too strong, not in the arms.

Then massage it for stabilization (always from below) , but you'll have to
repeat the job after a few days and more than once.

You'll have no chance with new springs to weaken them by the end of the
spring, the risk is high to bend the arm or worse bend the arm near the
coil.

To strengthen slightly a spring that is almost good, massage it from above
just near the coil, don't know why it works but it give just the slight
amount we need on a slightly too slow spring. (only disengaging the string
and putting it back suffice also often)

Bending the arms generally change too much the way the spring work, the arms
have an original shape that we should retain. a long time to learn ... It is
easier to weaken slightly the springs before installing the wippen actually.

Hope that helps

  To weaken a rep spring first disengage it from the groove. Then, using
your rep-spring tool you push down on the very end of the spring. Smaller
adjustments to the springs can be made by massaging the belly of the spring.

  i'm doing a regulation job on a Baldwin SD 10.  i've replaced all the
whippens w/ new ones and i'm wondering how i go about weakening the rep
springs.  i've taken my Hart spring tool and tried to weaken the spring by
pushing down on the top of the arc of the spring, pretty much halfway
between the jack and where the spring attaches to the whip (am i making any
sense at all?)  i tried adjusting the screw first, but the springs were
still too stout.  thanks for any advice.
  by the way thanks to all who replied to my last posted question.  the info
really helped.
