Cracked Lid

[Farrell]

I don't remember chestnut very well from my wood technology class - I'm sure
I had to memorize it's properties at some point. But I have cut up a number
of vertical pianos and the core wood was not poplar. It looked a lot more
like oak or ash, but clearly seemed less dense. Do you know offhand whether
chestnut is less dense than oak and ash (both of which are darn dense!).
