<DIV> Hi Jon</DIV>
<DIV> More good thoughts from the cape cods noreaster Tech=
.. I
gave a technical on action balancing last night mostly on anaylsis &
diagnosis. It was fun. I appreciate this taking it to the next level approac=
h
& will try it straight away.</DIV>
<DIV> Presenting material in technical form always helps to solidify i=
t my
own head.</DIV>
<DIV> Regards</DIV>
<DIV> Dale</DIV>

<DIV>Ultimately the best scenario, inertially speaking, would be to gradua=
te
the weight of the hammer heads themselves and group same-weight/knuckle he=
ight
shanks. But most hammer sets are</DIV>
<DIV>so erratic in individual weights that it takes invasive procedures to=
have them comply.</DIV>
<DIV><BR></DIV>
<DIV>Matching shank SW to hammer weight has proven to require minimal
intervention for</DIV>
<DIV>a smooth SW curve.</DIV>
<DIV><BR></DIV>
<DIV>First, I bore and taper the hammers.</DIV>
<DIV>Weight them and plot them on a graph.</DIV>
<DIV>Select shanks accordingly and install them on the rail. (# on undersi=
de
next to knuckle)</DIV>
<DIV>Hang hammers.</DIV>
<DIV>Remove h/s/f from the rail.</DIV>
<DIV>Cut the protruding shank off with a band saw and rough cut an arc.</D=
IV>
<DIV>Set up fence to trim tails on disk sander to even length.</DIV>
<DIV>Arc tails.</DIV>
<DIV>Weigh SW and plot on chart</DIV>
<DIV>Adjust SW</DIV>
<DIV>Install h/s/f on rail.</DIV>
<DIV><BR></DIV>
<DIV>I sounds like a lot of work but it goes fast. I like to arc the tails=
after hanging the hammers</DIV>
<DIV>to produce a nice finished edge. I also ease the edges (sides and bot=
tom)
of the tail molding</DIV>
<DIV>to remove the sharp corners with a file.</DIV>
