Renner repetition springs

[David Love]

You have to do a rough regulation of the spring by bending before you use
the regulation screw.  A gentle pulling down of the spring  before
installation will take some of the tension off.  My general procedure is to
first make sure that the regulation screws are set at approximately the
same height somewhere midrange where you can easily go up or down.  Then
after I install the wippens I go through and with a spring tool push down
on the upper part of the spring to take tension off and try and get the
tension close.  Then I go back and fine regulate with the screw.  It
shouldn't cause any distortion of the spring.
