I kind of figured BL Maple was marginal, but thought maybe some builders here had had some success.  It is seductively tall and straight before it matures.  I know vine maple well.  I spent many years on the Olympic Pennisula and had access to vines that had diameters of 6" plus and relatively straight if you searched hard enough.  I collected a few logs with thoughts of bow making, but life back then was good at throwing wrenches.
Gordon, I am a big fan.  I live in your general neck of the woods port/vanc. area.
Jude, great link.  I copied and saved the wood density info.
Aaron, good to see an aquaintance here!
I will see if I can find the Mt. Ash posts.  I hunt in Cent. Washington and the ash I am eyeing grows up at around 5000'.
I am a long time carver, but bow making is something I have yet to sink my teeth into.  You guys are all excellent inspiration towards that end.  masi, Greg
