<DIV>Subject: Re: Hammer Ratio</DIV></DIV>

<DIV>> Hammer ratio.... Hammer shank ratio....<BR>> <BR>> What =
range of
things could I possibly be talking about here eh ???</DIV>
<DIV> </DIV>
<DIV><FONT color=#800080>That was the =
question.</FONT><BR> <BR>> The
hammer / shank / hammershankassembly.... it constitutes a lever and =
a<BR>>
load... or just a lever depending on your point of view... ( I take =
the<BR>>
former and not the latter). One with two ends and a fulcrum... =
class
three<BR>> lever .... force applied between the load and =
fulcrum.....</DIV>
<DIV> </DIV>
<DIV><FONT color=#800080>I believe David and others are asking (as am =
I) exactly
a ratio of what measurement to what measurement. Hammer weight =
to shank
weight? Hammer length to shank length? Are you speaking of the standard =
Center
Pin to Knuckle Core and Center Pin to Hammer Center? If so, =
are both
these measurements taken along the same line? Or are you measuring =
from
Center Pin to Knuckle contact point and Center Pin to Hammer tip or =
somesuch. Maybe this is a Stanwood-type weight =
thing?</FONT><BR> <BR>>
Hammer shank ratio.</DIV>

it?</FONT><BR> <BR>>
