Downbearing/Unsubscribe

[Ron Nossaman]

Hi all (that's left),

First, an observation. Alan Crane's post stating reasons for signing off has
produced more than enough posted tripe in response to justify his attitude.
My opinion. Let's please just drop it and attempt to get back to something
interesting and, hopefully, USEFUL. 


Since I try not to bitch about something without offering an alternative (I
don't care *what* you've heard to the contrary) I've worked up a downbearing
poundage figgurer-outer chart. The Great International Math on Keys book,
available in Garage Sales everywhere, supplied the Trig and vector stuff. I
whipped up a Turbo Pascal program to print this sucker out for whoever can
use it. Look it over and see if you can make sense of it. Also, check the
figures against your own information and see that I didn't screw something
up. Shift happens.

 


Measure angle difference between string segments on either side of the
bridge. Multiply times tension for downbearing weight.
