Warped Action Parts

When I put the stack on a flat surface, all feet (except one) sit flat. =
Gravity seems to be pulling down enough to level it out. When I stand =
the stack up on one end (so the long axis is vertical) and place the =
feet along a flat surface, then I can see which ones are out of whack. I =
added the out-of-whackness of the stack feet to the out-of-whackness of =
the feet recepticles in the action frame and made suitable shims. I am =
now in the process of leveling keys, etc. and we will see how this =
works.

This is really horrible trying to do a job one can be proud of without =
being able to do what is needed. Oh, well, I guess we all have been down =
that road before. Thanks for your input.

     What is an "action standard"? I have now shimmed the action bracket =
feet. Is that what you are referring to?=20
    Yes, different terms for different learning backgrounds.=20

    End blocks all tight. Entire front edge of keyframe mates perfectly =
to keybed. What do you mean regarding checking the wippen rail for level =
- are you asking is it warped? Yup, it is warped a little bit, much like =
the hammer rail. Thanks for your input/interest.=20

    It doesn't take much warping to change the key dip.  If the feet are =
all the same length put the stack on a flat surface and you should be =
able to tell which ones are off.=20

       Terry, You may have to figure out which action standard is =
causing the problem and shim it. When you leveled in the piano did you =
put the end blocks in and screw them down?  Did you check the whippen =
rail for level?=20

        "The first thing you need to do is level the key frame on the =
keybed. Then=20
        proceed from there: level keys, set dip, install stack and =
regulate. " That was the whole problem here. I did level the key frame =
on the keybed. I did level keys (I even did a few with the frame in the =
keybed to see if it changed anything - it didn't). But when I install =
the stack to regulate, all of a sudden the key leveling is way out of =
whack! My stack is bending the rear of the keybed upward in the middle. =
I am in the midst of making appropriate shims so that stack installation =
does not stress the flatness of the keyframe, and installing additional =
rear keyframe hold-downs to work against the warped keyframe. "Nothing a =
new piano wouldn't solve!" Terry Farrell =20

          Earlier there was a discussion of bench regulation. However, =
there is a time=20
