Steinway D key levelling (Hamburg model)

[Isaac sur Noos]

Jay,

did you regulate well the pressure screws of the frame, (the glide
bolts) with the action in place, and the blocks screwed , before
beginning ?

Leave the blocks in place ans screwed tight for the leveling. As John
Page say, leave the punchings the same direction when adding paper.


Talking about the arch , the keybed is not flat, so your 65 mm
dimension should remain the same in the middle of the keyboard (more
or less)

We use a light somewhat flexible rule in spruce with a 3 mm curvature
approxamitively , so the play between the rule an the key is easier to
eyeball than trying to have a perfectly jointive surface.

it  also help to align perfectly the keys (new bushings ?) so the top
is square and the spaces between keys is even and neat.

But at first, seem to me you had a bedding problem, or you used the
leads on the back of the backchecks, make sense also.

I hope it can help.

Greetings.
