I'm not involved in moving many pianos, but I though I'd toss this
item in the information pool to see if it'd be useful to anybody or
to find out if some of the more experienced might know why it's not
such a good idea.
Probably the experienced restorers that load up grands all the time
would think it's a waste of time on their end. However on the piano
owner's end where the movers unloading the piano have no experience
with grands with drawers on them, it might be worthwhile.
I had an Ampico grand delivered back to me using what I thought was
a good idea to keep the left end of the drawer from getting cracked.
The follow that shipped the piano made up a plate using two 2 by 4's
nailed together and attached them to the bottom of the keybed where
the bass set of legs attach to the piano. In this piano, the legs
happened to attached to the piano with two large bolts so the bolts
were used to attach the spacer to the piano. When the piano was
unloaded and let down, the made-up spacer contacts the floor before
the corner of the drawer preventing any damage to the drawer.
It's a good idea to have something that can prop up the bass end of
the piano after it's been lifted and while you're taking off the spacer
so the leg can be attached as the guys that would otherwise be holding
it up for this procedure tend not to like doing that very long.
