Avery,

We can't remove the keyslip.  It's on there to stay in the Petrof 115 model
studios.  I'll bet the piano in question is a 115, (newest models now calle=
d
116s, I believe).  Since key interference with the keyslip is the problem,
and since moving the keyslip is not an option, it's a simple matter to nudg=
e
the keys rearward just a hair by shimming the keyframe away from the
keyslip.  This is what my procedure describes.

For the meticulous in the crowd, yes this might add a few grains of down
weight because of the capstan movement.  If this is unacceptable to you, by
all means, gather your planers, chisels, sanders and polyester repair kit
and reduce the thickness of the keyslip.

If, on the other hand, you want an effective, 20-minute repair, shim back
the keyframe.

Respectfully,

I don't understand this. I "thought" we were talking about removing the
key slip. Weren't we? :-)

Jerry,

I just did this less than a week ago.  It worked beautifully without
affecting anything else.

1.  Remove case parts.
2.  Remove keys
3.  Loosen keyframe screws (8)
4.  Place shims (I used business card slivers) between keyframe and keyslip=
.
5.  With the shims in place, tighten keyframe screws.
6.  Replace keys and case parts.

Time required:  20 to 30 minutes.

I have a Petrof vertical, and have the same problem.  I contacted the Petro=
f
rep. and was informed that indeed, it does not come off.  Don't you just
love challenges like this?

Some of them do not come off.  A couple of the Chinese pianos have the same
arrangement.  Makes for interesting adjustments when the keys hit the
keyslip.=20
Now there's a use for the 9 pound sledge. TP
