[CAUT] Whippen Rail

[Roger Jolly]

Hi Ric,
              I would start by checking to see if the spread is close to 
113mm.  If it is off, shim the rail to meet this parameter, regulate a few 
notes in the centre and at either end, and see what it looks and feels like.
   Shimming the forward side of the wippen rail will tilt the rail up a 
little and have a dramatic effect on the magic line.  I have fixed many an 
action with this trick.
   Now you have some food for thought.  <G>

Happy new year.
Roger
