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. =20 Kind regards, Peter Joris =20 _____ =20 From: pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org] On = Behalf Of St=E9phane Collin Sent: Friday, March 04, 2005 21:26 To: Pianotech Subject: Re: Restoring Collard & Collard Grand =20 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 ? =20 Best regards, St=E9phane Collin. ----- Original Message -----=20 From: Peter Joris <mailto:pjoris@pandora.be> =20 To: 'Pianotech' <mailto:pianotech@ptg.org> =20 Sent: Friday, March 04, 2005 6:25 PM Subject: RE: Restoring Collard & Collard Grand =20 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 =20 =20 ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
