rescaling tension

[Newton Hunt]

Tension is but one of the important factors in trying to get
a nice sounding scale.  You can play with the tension a lot
by reducing the wrap size and changing the unwrapped ends
around.  Balance is the key factor.  1500 pounds is only
0.033% of 45,000 pounds so I think you are well in the safe
range but think about reducing it by 500 pounds or so to be
in the save range.
