tuning pin torque

[David Chadwick]

Greetings,
Thanks to everyone who responded to my query. I have ordered a torque  
wrench from my brother ( a Cornwell tool dealer) to measure in/lbs. I  
have not done any previous tuning on the piano. I will be doing a  
first time evaluation to the pin tightness condition so I will do my  
best to give a report on the entire pin field for the builder. I  
think Patrick's advice on taking measurements with it stung close to  
proper tension is going to be the best situation for this condition.  
After all, that is operating tension needed to maintain tonal  
functions so whatever load is added to the pin should be considered.  
Terry, thanks for the figures that give me the general area to work  
with. I would also like to talk at length (in another thread perhaps)  
with what Stephane speaks about regarding the feel of the pin torque  
and what would be the comfort zone for smooth feel without jumping or  
having to trick the pin into holding because of less than acceptable  
pin tightness.

Also, Terry, here are some photo's of the "Autumn Leaves" Limited  
edition Model "D". The cabinet rim is decorated with various and  
colored leaves which carry the theme around the instrument. The plate  
has a autumn sky motif done by a outfit called "Wet Look". It does  
indeed look wet to the touch by all of the clear lacquer on the  
surface. The bench is very low. Rather uncomfortable but I guess if  
that is how one learns to play when they are young it has to stick  
with you.

My thanks to everyone. I'll comment on my findings soon.
