=2>Measure
the string heights, for example, at either end of the agraffe<BR>section,
let's say hammer 21 requires 1 13/16" bore and hammer 53 (or<BR>whatever)
requires a 1 7/8" bore. Measure and mark the bore distance<BR>=
on
the end hammers. Now clamp them together in the same manner you<BR>w=
ould
to gang file them. Make sure that the strike point end for this<BR>g=
roup
is in a straight line by butting it up against something solid.<BR>Now tak=
e a
straight edge and using the bore markings on the end hammers<BR>(21 and 53=
) as
a guide, strike a line through the group of hammers<BR>which will gi=
ve
you point at which you will bore on each hammer. Do<BR>that for each=
section, bass, tenor, 1st and 2nd capo. When you use the<BR>boring g=
uide
(I use the Renner one) you will have to eyeball where the<BR>drill hits th=
e
mark instead of using the premeasured gauge. In this<BR>case, a brad=
point drill will be the most accurate. Assuming that the<BR>string
heights don't undulate (which they might) you will then have<BR>bored the
hammers to the precise string heights within each section. If<BR>the=
string heights vary from section to section it doesn't really<BR>matter, y=
ou
will capture it accurately this way. If you are using a<BR>non-Stein=
way
hammer, like a Ronsen, order them not cut to length. Once<BR>you hav=
e
bored them, you can then cut the tail lengths to exactly 1" by<BR>making a=
small jig with a dowel that indexes off the hole you've just<BR>bored.&nbs=
p;
That will help give you uniform checking. After you have cut<BR>them=
to
length, cove them with a Forstner bit and then shape the
tails.<BR><BR><BR>David Love<BR>davidlovepianos@comcast.net
