Thanks David.  The alignment changes are both leaning a smidgen too far =
right or left and also I've got a couple where the tail needs to be =
pulled back slightly for a better alignment with the other tails.  I =
believe your descriptive procedures gives me enough to work with.  I'm =
most grateful.
Regards, Gordon Holley

  What kind of alignment change?  If the hammers are leaning one way or =
the other then you can heat the shank and twist the hammer slightly in =
the direction you want it to end up which will put a permanent twist in =
the shank when it cools (known as "burning the shank" even though you =
actually just heat them and don't burn them).  This can be done with an =
alcohol lamp or heat gun, or butane lighter in a pinch.  If the hammers =
are to be moved in or out on the shank, you must heat the glue joint, =
pull the hammer off, clean off the old glue and reglue at the proper =
position.  Hide glue softens easily when heated so keep the heat gun =
cool enough that you don't burn the felt or the wood. =20

    Hello List.  Very recently installed new grand hammers on new shanks =
and now need to make some adjustments in the alignment position of some =
of the hammers on the shanks.  I did use hot hide glue. =20
    What heat source should I use to soften the glue so that I can make =
the minute movements of the hammers on the shanks?.=20
    I do have an electrice heat gun, a butane tourch (don't want to burn =
up the hammers and shanks), an electric shank bender and a shank bender =
that you heat up with a alcohol lamp. =20
    I'm going to need one hand on the shank to hold it, one hand on the =
hammer to make the adjustments, how is the heat source positioned on the =
shank and hammer to soften the glue?.
    Many thanks in advance.
