pulley keys - special tool from Oliag (wood washers)

[Isaac OLEG]

Hello Newton,

The system sold by Oliag or Jahn, is using 4 or five "pins" that are
not driven by the old pin hole under the key, but by the larger hole
supposed to be made in the inside of the mortise at the factory when
the key where drilled for balance hole.

We may file or sand the wood of the underside so to see the larger
hole underside (still look for it on Yamaha keyboards )
then use this hole a guide.

On some other pianos the hole is so badly shaped (after rebushing jobs
have been done) that the precision is very poor. the good thing is
that the angle of the hole is more respected than with the Onesty
system (and this angle is more than I thought often) and that there is
a lip to stop the tool at the good deepness.


I will consider modify the Oliag system to use different pins as a
guide. I will have to find someone to make me these parts.

And the Oliag system does not include a washer making tool (but I
could find one).

Regards.
