[pianotech] Wurlitzer spinet ugh

[Tom Driscoll]

Jer,
 I think so.
 The whips don't move as they are screwed to the main action rail which does not move. The sticker cushions(nomenmclature ?) get lower in relationship to the capstans. Damper timing is changed but would also change when you raise the capstans. Same deal as I see it.
 Best ,
 Tom D.

  You know, you could be right Tom.  I'm picturing lowering the rail which would move the wippens lower, which yes, will eliminate lost most alright but, wouldn't it also leave the possibility of less after touch if the capstans actually needed to be moved up for the compensation instead?  Hmmm, got me to thinking now..  Especially if dampers are barely coming from strings from normal wear and tear or, am I visualizing this funny?

    I might add that you will have to be careful in doing this.  If there is not enough after touch when you lower the rail, you will have bobbling hammers.  You may want to check one or two in each section, bass, tenor, treble to see what kind of feel you have in this before proceeding all the way with the others.  

     

    Also, if they keys are not level, that will make a difference in your aftertouch as well.  It will be inconsistent.  While lost motion eliminates a lot of problems, the rail will still have to be set at the proper height first.  Usually, when the blue screws are set, that is about where the action belongs, but nothing is set in stone with pianos.  

     

    I do the same as Tom, removing keys, turning the capstans, getting a feel for how many turns are required before putting it back in and then do a whole bunch at a time once I get the feel for it.

    Jer,

     I'm not following you on this one. When you lower the rail it is the same as raising the capstan. In either case the whippen starts moving earlier in the keystroke and no matter what the aftertouch situation there will be more aftertouch after moving the rail and less chance of bobbling.

     Just my take,

    Best wishes,

    Tom D.
