Hi stephane,

=20

Yes, I=92m from Belgium (Limburg).

Maybe we can meet sometime are you from the area of Brussels?

=20

I will try with steelwool, where do you get an antioxydant (in Belgium) =
for
steel(iron), I know you can find them easy for silver and copper but I =
don=92t
think they will do the trick.

Kind regards,

Peter Joris

Hi Peter.

=20

I think, to remove old strings, it is very important to avoid kinking =
those,
or they will break.  When you release tension on old strings, pull on =
the
speaking length while you turn the pin, so the coil unfolds straight of =
the
pin.  after, you can clean the string with steelwool and d=E9oxydant =
(anti
oxydant ? what is the english word ?) product.

=20

To determine what steel was used in the piano, I would rely on in situ
breaking test, knowing that in a piano, and certainly old strings having
some fatigue of being bent many times, the breaking point is lower than =
what
you would encounter on the same new string in a laboratory.  I believe =
in
those times the strings were tensionned about a major third below their
breaking point, which is relatively higher a tension than modern scaling
shemes (often a major sixth). =20

=20

By the way, are you from Belgium ?

Best regards,

St=E9phane Collin.

Stephane,

=20

The sound is rather good, at least as good as it can be because the =
hammers
are severely worn, this makes the treble to hard and the bass to soft.

The sound is not comparable with modern grands tho, still firm, not to =
sharp
with a spark of briliance in it, not glassy as I read in the modern =
sound
treath.

The end result will very much be depending on the hammers

I was thinking of refelting the hammer, now I only have to choose the
felt!!!

=20

I would be nice to know what the correct age of the piano is, this could
help me in choosing the strings, I cleaned the bass strings already, i
tested 2 bass strings and they sound a bit better after the cleaning but
this will show in the end

The plain strings are so rusty that I don=92t know how to clean them. Do =
you
have a suggestion?

=20

Kind regards,

Peter Joris
