[CAUT] after ring on bass damper

[Joe Goss]

Hi,  Samic products back about 5 to 8 years have pinning problems The center 
pin issue can not be eased with any oil or sizing method. Only repining will 
work.
The cause is a combination of too much glue, graphite on the bushing or 
flaking of the plating on the center pin.
So far I have not had a call back on the ones that have been reamed for the 
correct size center pin.
One piano had a sudden seizing only after 30 minutes of playing. Almost 
could set your watch to it. Very hard to catch the offending center pin on 
the wippen assembly.
