Lowrey grand problem update

[Andrew and Rebeca Anderson]

John,
Try inserting the keyboard in without the action stack and watch what 
is happening.  Watching it is worth a thousand words.  Sounds like 
the damper underlevers need traveling.  That or the front key 
bushings are so worn that the keys are loose and the back end is 
swinging over far enough to catch the neighboring damper underlever.

Had a brand new chinese grand do that at the store here.  Had to 
re-travel almost all the damper underlevers and not all in the same 
direction.  They called up and wanted to know how much I liked the 
piano and would I like to order more: uhmmmmmmm NO.
