[CAUT] New Scale/Scale Stick

[Ron Overs]

Ric,

Regarding the wood which was used for the bridge, 
it probably isn't maple, but Sycamore. Both are 
from the family Acer, but one is sacharum (rock 
maple) with an ADD of 7.0 to 7.2 gr/cc, while the 
other is Acer pseudoplatanus, with an ADD of 
around 6.0 gr/ cc. Bösendorfer used to use 
pseudoplatanus for their bridges, and it was 
inclined to allow the bridge pins to stand up. 
They both look the same but the rock maple is the 
real McCoy.

Samual Wolfenden wrote about maple being weaker 
than Beech. He was referring to psuedoplatanus 
when he was writing about maple. He knew.

Best regards,
Ron O.
