One of them wouldn't grip at first, so probably the reverse is true, too =
(Titebond preventing CA from gripping).  I used a different bottle of =
CA, and that seemed to help, but the first bottle worked on the others.  =
I guess I should have scraped both wood surfaces first; obviously there =
was some glue there before (it looked bare, though).

Those Kawai "black jacks" are looking better all the time...

  Yeah, as long as the anticipated follow-up work was jack replacement, =
rather than gluing with Titebond. I should think that application of CA =
to the mating wood surfaces would pretty much ruin a good Titebond glue =
surface.

    I agree, a little titebond applied with a toothpick or such and you =
have a good repair.  I wouldn't have a problem with a drop of CA to all =
the rest to help solidify them for the time being...

    Cy asked: " why are those =3D
    jacks made in two pieces to begin with?  Is it just so they can fail =
in =3D
    a repairable way if regulation is off (too much aftertouch)?"

    Cy,
    Being the maker of obsolete action parts, I can say the Jack is the =
most difficult item to make. (just close your eyes and try to imagine =
how that configuration is cut!) It's made that way, because it's better, =
IMO
    BTW, I hope you are prepared to replace those jacks, as in fairly =
soon, as CA doesn't last very well in Stress applications. Please don't =
do that anymore. I don't care if it is in some PTG manual.....it's a bad =
way to repair something like that! Especially in a high end piano! =
Yikes!
