  My major problem is I'm alone here in Panama. There are no other =
technicians around that could possibly help me in a dream. If this =
Baldwin is so particular as to how the string is put around the hitch =
pin, God help the ambassador's piano if she gives the job to someone =
other than me. I will have to buy a down bearing gauge and learn how to =
use it. I have already sent an email to Baldwin to get information as to =
the stinging scheme and the down bearing measurements. Thanks for the =
input.

OK, then. The down and dirty proceedure:

You might start--if you've not already removed the original strings--by =
measuring the height of the originals off of the plate surface. The =
first & last of each section plus one in the middle of the two upper =
sections and the bass and a couple in the tenor. Combine this with a =
measurement of current string bearing and you'll have a good idea of =
where to start.=20

After the new strings are back on (and before pulling the whole thing =
back up to pitch) set the measured samples back to the original height =
and level out the rest appropriately. Don't worry about the setting of =
the individual strings, make them nice and uniform. Now chip the strings =
up to about 1/2 step flat and check string bearing. Baldwin's tend to =
run a bit light.

This assumes, of course, that you got the plate back in at the original =
elevation. You can ensure this by measuring down from the top of the rim =
to the top of the plate at each plate bolt location.=20

Take lots of notes.
