What would the jig have looked like? Also, which tool do you prefer for spoon bending?

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...

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)
