Yamaha C7 parts

[David Renaud]

Hello

   I understand Yamaha will sell a prehung set of hammers
shanks and flanges for a C7. Unscrew the old, screw in the
new, regulate, voice.  

   Is it worth doing it this way relative to cost. I heard
Yamaha recently really increased prices for these parts.
What is the approx. cost(parts) of a set like this, and is this 
the best way to go. 

                                                   Thank You
                                                   Dave Renaud

    Anyone out there know what size allen wrench is required for a Samick Lyre? It is a model SIG-50 and serial # GJL0181. I looked in Pierce (1998 edition), and such a serial number is not listed, so I don't know what year the piano is. Lady said it was new in 2001.
  Don't know about 2001, but the pianos we have use a 9.5 mm allen wrench. To save you the math, that's 9.5 x 25.4 = 0.374" and that is really, really close to 3/8" (0.375"). So, pop down to your favorite hardware store and buy yourself a 3/8" drive socket with a 3/8" allen insert and have at it.

  That's the good news. Now, for the not so good news....

  We have two new Samick-built pianos on the floor. The cheapest of them (built in Indonesia) has a nice iron block with a groove running down it into which there is a piece of rather crappy felt liberally coated with graphite which is specially designed to instantly glaze over and cause the pedals to stick. This system is easily repaired with some better felt and a bit of Teflon.

  The system I just tried to fix today is a whole other matter. Stamped metal and flimsy plastic bushings reminding me of the worst Aeolian ever had to offer. If it's one of these systems -- good luck. They are not designed to be repaired. At least not easily.
