Anne, We didn't calculate string tensions - just used a micrometer to match the dimensions to Malcolm Rose wire for the pianos of this era. Is this an incomplete way of doing it? Thank you. Mark ---------- Mark, You don't need to bash these pins in, nor should they be anywhere near as tight as in a modern piano. The tensions on the strings are not as high as for a modern piano. I trust you did your homework and analyzed the original wire and calculated out what the tensions and strains should be for A435? You shouldn't need a pinblock support unless you feel the need to bash too-tight of pins in really hard. aa From: "Mark McConnell" <mconnell1 at instruction.com> [ Save Address ] Reply-to: Pianotech List <pianotech at ptg.org> To: pianotech at ptg.org Subject: pinblock support in square grand Date: Sat, 22 Mar 2008 23:17:15 -0500 I am assisting a tech in restringing a circa 1840 square grand. There doesn't seem to be any way to use a pinblock support when hammering in the new pins, since the case is built around the block. Should I assume support is not needed? Does anyone have any experience with these? Thank you.
