[CAUT] Black on Black... (Jack alignment)

[Ed Sutton]

Jim-

My eyes and back are such that there is no pain free way to do a visual adjustment of the jack tip to knuckle core on any piano, let alone a Kawai with Millennium action parts.

The nuckljac will do a very, very fast job of first pass jack tip regulation, but since it uses the neighboring knuckle as a reference, it is only as accurate as the knuckles are consistent.  It's necessary to do a second pass holding down the hammer head while pressing on the key.  Both passes take less time than it would take me to do a visual regulation...which would still require even more follow up testing.

I think Mike Wathen's method using the pinblock to hold the hammers is neat and (once he said it) self-evident.  It leaves one hand to turn the tool, one to press the key, so I look forward to trying it.

I am very grateful for the nuckljac invention.

  Thanks Cy,

   

  This should work very well on Kawais, which are all so consistent. On some of the pianos here (BYU) where knuckles have been moved, etc. each jack/knuckle must be adjusted to itself and not its neighbor. Lots of inconsistency. But of course, those parts are not black so I can actually see them!

   

  I'm gonna get me one of these though. One can't have too much stuff.

   

  Regards,

  Jim

  There's this new product, which I haven't tried:

  But I thought Don put a white line on the jack for us, just for regulation?  I can't see it in the pictures...
