[CAUT] WN&G capstans

[David Love]

Brass 5.5 grams
WNG   1.7 grams

The difference of 4 grams is seen through the ratio of the capstan placement
on the key reducing is effective weight at the key by about 1/2 which makes
a difference of 2 grams at the key.  The brass capstans cost $44 per set,
the WNG about double that.

WS&G says they are 1/3 the mass of brass capstans...they don't say in grams
what one weighs...I think the low friction and non tarnishing aspect is
worth a check...so no one has just replaced capstan...DW, UW, friction
before and after?
