Jumping Pins

[Pianotoone@aol.com]

The piano is a Kohler & Campbell spinet.  25 years old.

Strings, hammers, dampers and cosmetically the piano is in excellent
condition (for a PSO).  It hasn't been used much.

However it is untunable because every tuning pin above the bass section is
jumpy.

The size of the pins is #2.  I tried chalk.
I replaced one pin with a #3 after reaming out the hole with a #3 reamer.
 Helped only slightly.

I replaced another pin with a #4 after reaming out with a #4.  This seemed to
be less jumpy but turned really hard.

I think replacing the pinblock is not an option due to cost.  But seems a
shame to junk the instrument when the rest is in such good shape.

I have heard of
1.  Putting varnish in the pinholes.
2.  Swabbing out with naptha.

What does the list suggest?  I told my customer I was going to the internet
to do some research, so we are both anxiously awaiting the wisdom of the
august body.  Many thanks from "where the heck is spring gone to Michigan."
