This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Hello Peter ! How is the sound ? I recall having heard 3 Collard & Collard upright = pianos, and they all had the same funny sound like if there was way not = enough tension in the strings. It made me think that those were = designed to be tuned far higher than 440. Just curious if the grand has = the same issue. Period hard drawn iron strings reproductions are available from = different sources : Malcom Rose (www.malcom-rose.com) (you would = probably choose type C) ; Stephen Paulello (he's got a nice chart for = deducing (following his assumptions) the right string quality after the = string length, the gage and the diapason) ; Pure sound = (www.puresound-wire.com) (but this wire will probably be too stiff for = the Collard & Collard). But those strings are a modern mild steel compromise, not the real iron = stuff. Stephen Birkett had a project for reproducing the period iron = equivalent. I don't know if he already finalized this. Some nice info = here : http://real.uwaterloo.ca/~sbirkett/historical%20wire.htm Beware, when rescaling such an instrument with modern wire you have a = great risk to over tension the piano, leading to pinblock failures = and/or case failures. And if you rescale with particular tension in = mind, you could end up with not enough tensionned strings that will = sound funny. Many restorers here will first try to save the original = strings and clean them. Best regards.

There is a number on the plate "K2" is this the type number? It is = about 183cm (6ft) long. =20 Is there anybody out there who has done this before? Im looking for information about what kind of strings to use for the = restinging, what felt to use for refelting the hammers etc. Actually I can use any tip available, this the first time I am doing = this, this will be a great for learning. =20 Sound board is fine, the veneer of the case is rather bad (a lot of = work), the pinblock feels still good on 1 or 2 loose pins. It was tuned to A440 and it holds very well. =20 I am thinking of a rescale, so it can be tuned at A440 afterwards with = a lower tension, doess anybody has experience with this? =20 Also I would like to take out the plate for refinishing but it goes = all the way into the case wood, I did not take any veneer of to see how = it is constructed, maybe any of you know this? =20 Any help will be very much appreciated, =20 Kind regards Peter Joris Pianotuner (maybe becoming rebuilder) =20 =20 =20 =20 =20 ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
