tuning pin torque

[David Chadwick]

Patrick,
Oh yes, I also plan on a fine tune procedure after I take all of the torque 
measurements I fell necessary. I agree with you in that the tuning process 
helps us become more intimate with the condition and idiosyncrasies of all 
the components involved. Then, perhaps, I can express any thought's I might 
have as to the pin tightness problem to the builder.

I don't have a digital type of instrument to measure humidity. We usually 
have stable levels around 8 to 18 percent RH. Currently we're in a monsoon 
weather pattern and levels are 50 to 60 percent. It won't last long.

I did send the pic's to files at ptg.org so hopefully they will be published.

Thanks
David Chadwick
