(And repairing the pedal lyres that end up mangled by this method.)

Yes, of course, I forgot to add that I had previously examined the lyre
and determined that it was strongly built, all glue joints were solid,
and it was well attachable to the piano.

I have seen the lyres made for Zimmerman pianos (before the Berlin Wall
fell), and some Korean pianos, and on those I would never allow anyone to
rest the piano on the lyre.  Some other cheap pianos are so poorly built
that the keybed would bow so badly that it would damage the grand action
and keyframe.

But I stand by my guns and tell you that I had this same argument with
the professional Steinway factory movers who insisted that all Steinways
are built to be moved this way.  I have used this method (after I was
convinced that it DID work) for the last 20 years.  I have never had a
damaged pedal lyre within that time period.

I do not, however, let "Doofus Piano Movers" use it.  I use it when I
have to.  The rest of the time I pay a mover to do it the normal way.

The technique was written out for a man who wanted to move it himself,
un-assisted, and that is the only way to do it.  The piano he referred
to, a Mason & Hamlin Ampico, is certainly built well enough to use this
technique on -- given that the glue joints in the lyre are all solid.

I also would never move a rental piano that way when it is moved every week
on the lyre.  That is asking for trouble.

However, now having read the response of Mr. Smythe, I find the piano is
foot pumped which means that it probably will not work at all because the
angles of the very wide pedal lyre/feeder box.  Even if you wanted to
rest the piano on the box, the angles involved would make the piano hard
as hell to tilt.
