Isaac,

Thanks for your advice.
I'll contact Desfougeres and ask if they can also put new leather on =
those special rollers.
I'll ask what method they use.=20
The hammers that I had get refelt from Abel were ok but as you say, they =
should have more experience with this.

I have recently restrung one of those parallel Erard Grands that you =
mention  (used the Roslau blue wire , single strings)
but left the original basstrings (still in good condition and  good =
quality) =20
Do you think the Roslau blue is not the right wire to use?
The results were good and yes, I agree, very nice pianos.
For me from the best ever made and I now better understand those people =
who does only want to hear
about parallel strung pianos. Fine and rich sound.
Tuning those is verry easy and pleasant.

Regards,
Pierre Gevaert.

  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?=20
    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

      Isaac OLEG

          I have been asked to reglue hammerheads that have come loose =

to clamp them.

        ???? Clamping ???? We do not clamp hammerheads.=20
         =20

          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 =

          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.=20
