I she got it for $5000 then do a complete rebuild with new board, block,
action, dampers, etc.  She'll have a nice piano when it's done for a
reasonable price.

Bushings, Strung w/#6 pins

 

Hello all,

Firstly sorry for the cross posting but I need as broad of a knowledge base
as possible on this one. Looking for advice, theories, suggestions.

 

I recently acquired a new customer, she relocated to this area from
somewhere in New York state. She acquired this piano "rebuilt and/or
restrung" from a music store for the princely sum of $5000 in 1977. She was
told it had been acquired from a monastery that had been closed, that it had
been rebuilt and/or restrung, she liked the tone and bought it.


She had a regular tech in New York who cared for it and kept it reasonable
condition for her.

When she moved here it had not been tuned for a couple of years due to the
move, the new(used)home not being ready and other factors. 

My first contact was in October when I was to clean and tune it, I found the
action virtually impossible to remove, the very large round headed screws on
the hammer flanges were catching and digging into the underside of the
pinblock. Since we were still well into the high humidity season I suggested
the cleaning wait until the winter tuning and just tuned it at that
appointment. I found it to be 25 to 30c flat through the bass and tenor and
a full half tone flat in the upper treble. I brought this to her attention
and suggested a re-tune as soon as the heating season was in full swing for
a few weeks.

We made the 2nd appointment for the second week in December, to clean, tune
and fix the squeaky pedal that had developed. The morning of the appointment
she called to suggest I bring whatever might be needed for a loose tuning
pin as one unison had gone significantly out of tune overnight.

I arrived, tried tuning the offending string and watched my hammer rotate
back. The coil was already very close to the plate so I unhooked the string
backed out the pin and sized it preparing to go oversize, it was a #6. Up to
this point I had not paid much attention to the pin size as it had not been
an issue, now looking at the rest of the pins, I could see they were all the
same(no.6) size. I had managed to remove the action by levering the action
rail down slightly to drag it under the pin block then once it was under,
just scratching it's way out. 

Oh and yes for those who will ask, I did try raising the glides to see if
that would help, it didn't

I had also noticed something odd about the action at a glance, the "felt"
around the bushings wasn't red, it was white. When I looked closer I saw
they were all Teflon bushings, the entire whippen and the hammer flanges are
Teflon bushings.

 

Someone, on purpose, replaced all of the original whippens and flanges with
new ones with Teflon bushings. Perhaps it had vertigris and this was a cheap
way of eliminating it for a dealer concerned with salability AND not having
it come back to bite him on the behind a few years later?

 

It has an average gram/touch weight of 60 to 62gms. It needs regulation but
shouldn't the lower friction of the Teflon bushings make for a lighter
touch? I have NO experience with teflon bushings advice please, remember
this action WASN'T designed for them>

 

The hammers don't appear to be anything extraordinary, they look like stock
hammers from Apsco or Schaff from the 70's.

 

Today I CA'd the bass and lower tenor  as a temporary way of tuning it until
she can afford to restring it, with a new block, I believe it is the
original block in it now.

The question she asked, to which I wasn't positive of the answer was, do we
need to replace the whippens and hammershanks/flanges due to the Teflon?

 

My feeling is yes, for historical accuracy and value, my hunch is it is
worth far less with the action parts it now has. Not to mention the poor
grade hammers and being in need of a re-string.

If I am wrong about any of this please tell me.

 

Flamesuit firmly zipped in place!

(grin)

 

Mike
