Tuning Pin Torque

[John Ross]

Hi List,
I was wondering, is there a table of torque measurements,
in inch pounds, for the tuning pins.
i.e.   too loose?
        loose?
         nice to tune?
         too tight?
I remember I saw one once, but I can't remember where.
Thanking you in advance.
Regards,
