pinblock support in square grand

[Mark McConnell]

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,

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.

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.
