raising damper lift to lighten touch

I take it this is 186 cm grand?  Since it has spoons that contact=
 the back of the keys?, I would have made a jig and bent the=
 spoons up a tad.  That seems much easier and you keep the=
 factory damper regulation...;-]

You need to check subtract upweight from downweight and divide by=
 2 to find if friction is line.  Check some flange pinning...

Subject: raising damper lift to lighten touch


Far flung friends and fellow techs,
 
One nice thing about doing occasional store work is that there=
 are lots of guinea pigs to try things out on before I do it in a=
 customer's home.  
 
Yesterday the manager of one of my store accounts said he had a=
 customer who loved the Seiler 186, but the touch was a tad too=
 heavy for her tastes.  I suggested the least invasive procedure=
 I could think of--raising the point of damper lift.  He said=
 okay.
 
I regulated the dampers by loosening all the wire block screws=
 and lowering the wires, using the tray(raised to the proper=
 point) as a guide.  I brought the lift point to where the hammer=
 was about 2/3 of the way to the string.  To the touch, it felt=
 like lift was beginning just before letoff.
 
I fine regulated them by adjusting the capstans.  (still doesn't=
 look quite as good as a Seiler factory job, but it's not bad at=
 all).
 
Also needing regulation were:
 
The pedal rod
The trap-stop capstan(what DO you call that, anyway?)
The damper upstop rail
The sostenuto rod
 
In the end, the touch weight was around 5 grams lighter, possibly=
 a tad more.  It felt quite good, and all of the dampers had=
 plenty of clearance.
 
Would regulating spoons or capstans be far more difficult or=
 offer other pitfalls?
 
This was my first experience with  this particular job, and it=
 came out pretty well, but I'd certainly appreciate any=
 suggestions from those of you who have more experience doing=
 this.
 
Thanks,
 
Dave (back on the list after being glued to the Tour de France)
