Grand Bending & Square Grand Cheek Lift

[Farrell]

Pretty easy - although easier on the square. Squat down five or ten feet in
front of the piano, and sight along the long edge. Look to see if that is
straight first. Then move over to the side of the long edge a few feet back
and carefully line up your line of sight such that the long edge, your eye,
and the far edge are in line. Then look all along the curved edge. By moving
about & sighting like that you can see pretty well if the whole top edge of
the piano lies in on plane. Of course, this does assume that the rim is of
constant height!

Thats how I did the square. If you are real careful you can see quite
accurately.
