Pierre,

Ask the job to be done by DESFOUGERES in PARIS.
45 rue Max Dormoy
75018 PARIS
phone 033 01 46 07 22 84
These are French pianos they know very well

They can too put new leather on the "backchecks" , on the rollers, and new
"galuchat' on the whippen lever.

Abel does the job too, don't know the result.

Frankly I am not absolutely sure these refeletings are not done in a press,
I just had a (retired) colleague who had all these individual wood clamps,
closing with a wedge, for these re-felting jobs, and Desfougeres have the
same)

But the pressure with these wood presses is as high that with the other
press .Refeltings are not done in hydraulic or pneumatic press, just the
traditional manual one, a modern press is used to put the felt in shape a
bit with warmth before gluing in the manual one.


I've seen Erard shanks allowing for modern hammers too (with a little dowel
at the extremity).
I guess these where originals. On these you have modern hammers.

These parallel Erard Grands where build for 100 years use, some have a very
lively soundboard yet, they have a very nice sound, the action is a little
special of course with a 64-58 -mm hammer /string distance.

If possible to use the correct strings on it the sound will be better.

Hope that helps.

Regards.

Isaac OLEG

P.S please let us know how they refelt (press or individual) if you ask.

  Isaac,

  I intend to let refelt the hamers of a verry nice Erard grand of 1927 wich
has a tiny sound due to the hamers beeing reshaped
  to often.
  And indeed there are no tails. Thoes that meen that it is more difficult
to obtain good hamers due to the impossibility to clamp the tails?
  Any good adresses in France? I was thinking to ask Abel, but i'm not shure
they can refelt such a hammers.
  Any way, just great pianos those Erards exept for their bizare kind of
hammershanks and hammers.

  Regards,
  Pierre Gevaert

    Richard,

    The metal clamps yet sold by Renner are indeed designed to clamp hammer
felt. That was done in ancient times eventually to glue some new felt on
multi layers hammers (and leather too of course)

    Another method involved the uses of a wood clamp, the Erard hammers
refelting are yet done as that, as they cant be mounted in a machine for
gluing new felt (no tails).

    These clamps are very strong, the surely could help to clamp back some
old felt, but the hammers are ruined anyway (as probably the piano ). And
yes for sure they don't really apply to modern hammer making.

    Friendly from

know the best kind of glue to use if not hide glue and best way to clamp
them.

      ???? Clamping ???? We do not clamp hammerheads.


        Any other information that may be helpful would be appreciated.  The
piano is about 30 years old and there does not appear to be any other
problems except rust formation on the pins and strings.  I realize that some
of the other hammers may become loose in the future and have warned the
client.
        Thanks, Paul Plumb

      A good wood glue should work just fine... Is this an upright or a
grand. Perhaps you might get a tech with some experience in fire/smoke
damage to take a second look at this instrument. Not all problems relating
to fire / smoke become all the acute immediatly after the event.
