<DIV><FONT face=Arial size=2>Phil Bondi and I dove into an 1890s WNG action from
a 6' 4" Knabe today to try and straighten out some basic action geometry. We
haven't got all the kinks worked out yet, but we seem to be getting
there. With only a large capstan move and removal of a couple leads, we went
from an action ratio of over 6.0 down to 4.9. DWs went from 60+ to 50
and less (I know, too light) and BW in the 36 to 40g range. We have a
lot of work to do yet, but it seems the capstan move described below has gotten
us into the right ball park anyway.</FONT></DIV>

<DIV><FONT face=Arial size=2>Most notable was a very large capstan move that we
will likely keep (unless someone so kindly informs us of a potential
problem the change might induce). The photo below shows the original capstan in
the background. The forward key had its capstan moved 10mm forward and 11mm
lower. The middle key had its capstan moved 13mm forward and 12mm lower. The
second photo shows the modified wippen heel. These lower positions put
the capstan right on the magic line at half blow. The capstan/wippen heel
interface went from a traveling, grinding, sliding affair and a note with 17g
friction to a perfectly interfacing union with no apparent sliding and a note
with 9g friction. We were amazed at the improvement in friction and interface
movement.</FONT></DIV>

<DIV><FONT face=Arial size=2>This strikes me as a rather drastic capstan move.
Has anyone else run across an action that needed such a large capstan move? As
our action ratio is down to 4.9 and key ratio is down around 4.8 with the
10mm forward capstan migration, we may move it back just a few millimeters. But
still it seems large. Is there some hidden pitfall I'm not
seeing? Comments?</FONT></DIV>
