Laws of physics in reverse?

[David Love]

If there's room on the stem get a second nut and put a lock washer between
them.

 John..Hate to burst your bubble, but a drop of thin glue gravitates
downwards to the nut and does the job. Glue under the nut can get involved
with any felt or leather washers.

Someone wrote back saying put a drop of glue on the nut - which I somewhat

disagree with.  IF the nut is truly getting tighter then the drop of glue

had best be placed UNDER the nut, not on the top of the nut as the drop

under the nut will prevent the nut from traveling downwards.  (small point I

agree.)

A customer called me the other day who has an old upright piano, a fairly

nice one.  But it has one unusual feature--either that or she is not telling

me everything.  The nut which adjusts the damper pedal tightens itself over

time to the degree that the dampers stand off from the strings, and the

sound just rings.

 

Is this really possible?  She claims no one tampers with it.  But every

visit I adjust it so it works properly, and my next visit it is screwed down

so tight that the dampers are off the strings again.

 

Anyone else experience this?  Can you explain it?  I can understand a nut

loosening, but tightening by itself baffles me.

 

Anyway, it's time to loosen the nut again!
