Not to worry about the CA glue. And warranty concerns have been duly noted.

Don't do anything to them like add CA glue.  A warranty claim should be made asap as they do not meet minimum standards.  Anything you do like putting CA glue may void the warranty.

The pianos are NEW; one year old or younger. Thanks, James.

That's too low.  What kind of piano?  Are they actually new or just new to you?

Thanks David for your response. My torque readings vary from 15-45 inch pounds. Setting the pin is difficult not because of flagpolling, but rather the pin turning loose. The blocks are maple, not multi-ply. Thanks, James.

Sorry, didn't finish.  Probably about 60 lbs is minimum but on a new piano you'd like to see around 90 - 120 but there is quite a range.

What kind of pianos, what is the torque (if you know), when you say difficult to set do you mean that minimal back pressure causes the pins to move or are they flagpolling?  There is no industry standard as the pinblock material and pinblock drilling practices will cause a wide range of torque readings.

Dear members:

I have recently purchased several new pianos and discovered during the initial tunings what I believe to be minimal tuning pin torque. 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
