Tokiwa parts (was Steinway K Double flange)

[Mark Dierauf]

Thanks, David - I'll try the protek on the springs. The set I got that
has the tight pinning problems went on my own piano, so repining them as
they go bad isn't any hardship. On the second set, I measured the
friction of every center before installation and marked it on the parts.
In this set I found only a couple of very slightly tight flanges.

I've also had problems with Tokiwa wippens that are similar to those
described.  In addition, last I checked, the leading edge of the jack
was
not beveled causing a bit more of a bump at let off than I like and
forcing
the balancier to regulate higher than I would like in order to insure
return.  Though all of these things can be addressed, it's unfortunate
that
they should have to be done on a new set.
