Plus the fact that whomever made them used hex core wire. Yuk! I attach a print-out of the results such a scale as this would give. As you see the lengths are, for practical purposes, the same as the 'O' and the scale is as crazy if not more so. Whoever published those dimensions had no idea how strings are made, since the total diameters given are the sum of the core and twice the diameter of the copper. This is nonsense, since the copper reduces considerably in diameter as it is wound onto the steel; for example they say that the top single, with 160 copper on a 20 steel will end up as 4.325mm, whereas it will in fact end up being more like 4.08mm. This is a huge difference. I can see no sense in their scale at all and truly it is rare to find such a _very_ badly designed scale. I attach also a print-out of a scale that I would use for this piano. I have no objection to making the strings either :-) JD -- ______________________________________________________________________ Delacour Pianos * Silo * Deverel Farm * Milborne St. Andrew Dorset DT11 0HX * England Phone: +44 1202 731031 Mobile: +44 7801 310 689 * Fax: +44 870 705 3241 ______________________________________________________________________ -------------- next part -------------- A non-text attachment was scrubbed...
