[CAUT] measuring wippen weight

[Garee, Anne E.]

Barb,

If it is tipping to one side, trim the damper felt on your scale pan jig
to off-set it a bit.  You can then turn the jig around for two different
angles.  Make sure you have soaked the jig felt in lacquer to stiffen it
and create a bit more friction.  You can also slightly rough up the
bottom of the angled flange that sits on the roller or put a bit of
spray adhesive on it temporarily.

Howdy,

 

I have some Renner Steinway wips that I'm altering to fit a Knabe.  Be
joyful that I'm not going to tell the story of all the testing I've done
on this action.  Anyway, besides replacing the flanges (obviously), I'm
having to move the heel backwards (toward the flange).  When the wips
were in their original state, the WW was 17.  Now with the heels moved
and the little/angled Knabe flanges on, I can't get the wip to balance
so I can get a reading.  Do I just hold it lightly against the "tower?"
or tie it with thread or use a rubber band or just ignore it?

 

This wippen set up is the best (of the many) I've tried--feels good,
less friction.  I'm just curious about the numbers. 

 

Thanks,
