<HTML><HTML>Hello List.  Back to my proble= m Yamaha C3 grand.  It has been suggested by others on the list that I check the pin torque.  I have researched the archive= s and also have read the section on the subject in Arthur Reblitz book Piano= Servicing, Tuning & Rebuilding.  His comment on tuning pin torque = is ". . if it takes less than 50 inch pounds, than the pins are probably too= loose.  I read one archive comment on loose tuning pins by John Tuttle.  He sta= tes "I believe optimum torque to ne 12 Ft./lbs. I couldn't find anything more specific in the archives on the subject. Reblitz says "inch pounds" and Tuttle says "foot pounds".  Which should it be "Inch" or "Foot".  I will assume that it can be eith= er. And, is there a conversion on inch to foot?. Does anyone have some suggestions on tuning pin torque.  I would assume= that the torque would be basically the same wether it is a grand, spinet or= full upright. I thank you all in advance.
