Asharrow, thanks, I'm not saying it makes a difference .....I'm asking if it does.
The link willie gave indicates that a living northern hardwood tree takes active measures to change some of its internal chemistry. reduce free water content, etc. in order to prepare for winter. So I'm asking if that type of timber,cut in a warmer month, which hasn't taken these internal biological measures might see some internal structural damage and reduced physical properties. Maybe so, maybe not, I personally don't know .... that's why I'm asking.
Here's why I'm thinking about it. Some woods which grow well further south of here -- I think hickory is an example -- you guys know which ones better -- don't work well as bows subjected to subfreezing use. Some others, like Finnish birch bows , made from woods which grow far more northerly, apparently do well in subarctic areas.
So what's the difference in the woods internally, and were they cut for bow use in summer or winter. Lots of interesting questions to me since, those very woods grow here, and maybe I'd like to shoot 12 months of year without worrying so much about the selfbows I make for that.
