Re: Petrof keyslipJust a thought: If you can flex the key slip at all, =
then try this:
1) Pull out two groups of 4 or 5 keys spaced equi-distant along the key =
frame NOT where there are front to back cross pieces.

2) Using a right angle drill, drill a hole parallel to the key bed thru =
the front key frame almost all the way thru at each of those locations. =
Leave a half inch or so of wood.

3) Using a proper length dry wall screw, screw thru the remaining wood =
until you touch the key slip. Remove screw and blunt the end. =
re-introduce the screw, then adjust the in/out of the key slip as you =
wish.=20

Sort of like the way Wurlitzer used to do it, only coming in from the =
other side of the front key frame. No having to go thru the hassle of =
pulling the whole key frame assembly and shimming. Should be doable in 5 =
minutes, assuming as I said, the key slip will flex with a little force. =
Bet it will.

  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 called 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 nudge 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,

      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 Petrof rep. and was informed that indeed, it does not come off.  =
Don't you just love challenges like this?=20

    Some of them do not come off.  A couple of the Chinese pianos have =

    Now there's a use for the 9 pound sledge. TP=20
