<DIV><EM><STRONG> Hi J D</STRONG></EM></DIV>
<DIV><EM><STRONG> Perhaps I did misunderstood but if the hammer is
to strike the string at a right angle it preculdes that the hammer
shank will have to slightly overcenter & that the bore length will be
slightly less than the String height minus the center pin height to achieve
this. I'm assuming you may be hanging the hammers at a right angle to the
shank. In order to hit an angled string plane with the hammer & have the
string and hammer at right angles to each other ,somethings
got to give. See what I mean?</STRONG></EM></DIV>
<DIV><EM><STRONG> Perhaps sharing your boring protocol will clear up what
your saying. Was mine unclear?</STRONG></EM></DIV>

size=2>Broadly speaking I agree with Dale Erwin, as far as he goes, except
<BR>that I aim to have each hammer strike the string at exactly a right
<BR>angle. I don't follow the reasoning as regards over-centring. It
<BR>might be argued that the shank bends under a heavy blow and therefore
<BR>tends to cause the hammer head to under-centre slightly, but given <BR>the
rigidity and thickness of modern shanks, particularly the <BR>hornbeam ones, I
doubt if this is significant and would need to see a <BR>slow motion movie to be
convinced. Nevertheless I think it would be <BR>a valid research exercise
for someone with the equipment, if it <BR>hasn't already been
done.</FONT></DIV></DIV>
