List,

            I'm servicing a Steinway M. "Sapelle "Veneer. Very pretty.
This piano is two years old and my client was complaining about
playability. Lettoff and drop was all over the place, tight balance rail
holes, jacks needing alignment to knuckles. All this corrected with the
usual procedures, including Mclube on key pins, Teflon powder on
knuckles. Also noticed what looked like Graphite grease in the balancier
(rep-lever)spring seats. 

            I found the hammer shank action centers to be very tight.
Two- Three swings only. I had no luck with protek on a sample.

            I consulted with Steinway N.Y. and spoke with David Kirkland
in Tech services. He was very supportive but had never heard of this
problem before. He mentioned that these centers were treated with liquid
Teflon and shouldn't be tight---" permafree two" I think he called them.
When I mentioned protek David suggested that it generally is a short
term fix and suggested alcohol -water treatment to resize the bushings

            So--- My questions trusted colleagues:

            

1.      If treated with liquid Teflon at the factory, why would Protek
CPL (Teflon) be short-term in the field?

           

2.      Will the alc-water treatment be effective on a center so
treated?

 

 

3.      Have you seen tight centers on other new Steinways?

 

4.      Could that black stuff on the reps really be graphite and is it
factory applied?

 

 

 

As I mentioned the gentleman was supportive and authorized the
aforementioned warranty service, but I think I might have to ream and
repin at least a portion of these.

Opinions?
