Hi Denise, Thanks for your response. The pin torque readings are anywhere from 15-45 inch pounds. Not tight at all. I am familiar with your experience on the Hardman, but this is a different type of spongy; loose.

Hi I have no answers for you. but . . . . yesterday I tuned a Chinese Hardman grand. The pins were tight, but so spongy feeling that I felt like I was bungie-tuning. Awful!

The pins feel "spongy" and difficult to set. Is there an industry standard for pin torque, and if so, what should that torque value be in inch pounds? Any data on this subject would be greatly appreciated. Sincerely, James Williams, RPT Dallas Chapter -------------- next part -------------- An HTML attachment was scrubbed...
