[pianotech] Harpsichord Tuning Pin Torque?

A good source for information about Harpsichord construction can be found in
the book "Harpsichord Design and Construction" by Evan J. Kern, Van Nostrand
Reinhold Company, ISBN 0-442-23348-5. In the section on drilling the tuning
pin holes he suggests taking a sample of the wrest plank and drilling "a
series of test holes in varying diameters smaller than the diameter of the
tuning pins.... The tuning pins should turn smoothly under firm pressure....
if the tuning pin turns too hard and with a jerky motion, the hole is too
small." pg. 92.

 

I was once told that it was ok for the pin to be so loose that you could
turn it with your fingers, as long as it stayed at pitch.

Anyone know the approximate tuning pin torques of a harpsichord?
