<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>So 12 ft.-lbs. equals 144 =
in.-lbs. (it's
feet times pounds, not divided by). I've tuned many old uprights with =
tuning
pin torque less than 50 in.-lbs. - too looses for my liking, but seems =
to hold
a tuning pretty well. I find that anywhere in the 80 to =
150 in.-lb. range
will be fairly tunable. If I had to specify my favorite, I would say =
100
in.-lbs.</FONT></DIV>
