Kawai metal cabinet parts

[llafargue]

These are KS2F's and could also be grey market.  If you grab the two
toes (while the piano is standing) and wiggle, they creak.  Nice pianos
otherwise. It's not a pedal, but in the cabinet itself. I've oiled the
brackets (that are inside affixed to the toe back and sides of piano
itself) and the creak has stopped (at least for now).  I think that's
the first time I've ever used oil on a piano.  I was afraid someone
would see me holding the can!!  I'm not certain about the permanency of
my fix, so thought I'd ask the more Kawai experienced.  There is a screw
under the caster as mentioned, but EVERYTHING showing and some not, has
been tightened.  As to the welding, if you are referring to the welds
visible on the bottom, they are fine, if it's inside the "box" that is
the toe, I dunno. Thanks to you all.

Lance and Jim,

There are some older Kawai models that had metal legs and maybe toe
blocks as well.  I think they were BL models - ?? Not sure.

If I remember correctly, there are screws from the bottom around the
caster that tighten the leg to the toe block, and those could be a
possible source of noise - although I've never seen it happen.

More commonly, the trap lever pivot brackets and spring cups can squeak,
and there are screws underneath the trap lever that hold things
together.  This is a common 'hidden' squeak source, as are the toe rail
/ bottom board screws you mentioned.  To check, pop out the pivot pin
and take off the offending trap lever, turn it over and check the
screws.  Also check the spring cap for cracks.

Kawai parts can get you replacement trap parts if needed.  (800)
