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.
