tight young chang bushings

[piannaman at aol.com]

 Gene,

I work on a Samick of more recent vintage.? It is on this piano that I learned the art of re-pinning...:-)

The center pins on this particular piano, as well as others of similar vintage, appeared to be covered with graphite or some other gnarly substance.? Whatever it was, it's became kinda crusty, and some of the pins were really hard to budge at all due to buildup of crud.? And it was all over:? jack centers, wippen centers, hammer centers, rep lever centers, and even some underlever centers.? At least there are fewer centers in an upright.

I don't think any warranty will cover a piano as old as the one you're client owns.? 

Good luck!

Dave Stahl

Have a 1983 Schaffer and Sons 53" upright?- all action centers are tight and they get worse with alcohol water treatment.


Is this the?Young Chang contaminated bushing?issue? I think it is made by Young Chang, not certain.


Is there a remedy other than repinning or parts replacement?


Is there any hope for help from the warranty/manufacturer?

I may be mistaken but I think the Schaefer & Sons from back then were a Samick product. Does it have laminated bridges? I know Samick did?at that time. We had a couple of techs here in town that started?carrying Samick about '86 or '87 and?a tooner that had a Schaefer & Sons grand that?had some problems?that he felt made all Samicks no good because of his problem Schaefer grand.?

I do know that everyone complained about Samicks very LOOSE bushings at the time. I recall that frequently they weren't all glued in, if you tried to repin with a larger pin to tighten them up the whole bushing would come out.?So I would hazard a guess that perhaps this is an aftermarket problem, perhaps some rebushing a little too tight then some spraying to unstick them? As I say, just a guess from what I know and remember of Samick/Schafer at the time.
