pin blocks

[Leslie W Bartlett]

I'd like to hear some discussion of delignit pin blocks.  I've
encountered on  on a Samick (sorry to bring that name up.....) at the
church where I do a bit of music, that is causing me some concern.  It
has s number of loose pins. I replaced a couple with larger pins about a
year ago, and now, they're loose.

I tuned a Kawai today that I tuned about a month ago (pitch raise)  At
that time it had about thirty very loose pins. Today, pitch was
considerably sharp, and the pins were tight.  That's good for now, but
what happens with a decade or so and some more dry weather???????????

I'm curious as to how more experienced technicians view pinblock
materials.

Thanks
