<DIV><FONT size=2>Recently rebuilt a S&S model S c 1931. The =
measured
key ratios for the sharps were .48, for the naturals .51. I =
considered
moving the capstans on the sharps so the total leverage on each would be =
equal. But when I started to set up samples and take measurements, =
I found
that the FW pattern was smooth and the corresponding SWR's were =
equal. I
would have expected that sharps to need less FW or, with a smooth line =
front
weighting, a varied SWR. Somewhere in the system something =
else
compensated for the different key ratios. Question is where? =
All new
parts, strike weights smoothed, BW all equal. the job is now
completed. I left the capstan positions alone and the FW curve was =
pretty
smooth, SWR all 5.9 - 6.0. A few bumps along the road as is often
the case, but one would have expected 6-10 grams less FW on the
sharps. Any opinions?</FONT></DIV>
