Title: Norawy Maple Seciific Gravity?
Post by: snedeker on June 22, 2007, 02:52:24 pm

Anyone know what this might be?  Close to sugar maple?  I have a nice stave.

I looked it up one time and seems like it was close to sugar maple. I have a couple staves too that I need to play with.

I can't find a hit anywhere about it on a search engine.  Weiht per cubic foot would be ok.  My general understanding is that its a hard maple generally.  My stave feels pretty light - for example compared to the oak piece of similar size, both dry, right next to it in the stack.

Norway maple is markedly lower in S.G. (~.55) than sugar maple, although denser and stronger than big-leaf maple, and a fine selfbow wood.

what few references I could find in a web search are extremely variable, listing it as anywhere from .56-.68. I do know that the wood in hand is much heavier and harder than red maple, which is in the low-mid fifties.

   Dave, thats one of the reasons I started using mass instead of demensions, just too much variance between specimens of wood having too much affect on performance. Steve

Thanks for the input.  I am a yahoo man and it wouldn't give me anything.  I'd say the piece I have is MAYBE .60.

Don, I didnt mean to be a doubter of our correspondence/.
I'll shut up and make a bow out of it.
