I guess there are three main factors
1. resistance to rot
2. strength to weight, and-or resistance to cracking/splintering ? ? ?
3. workability ( dont know what that really means either )
Maybe some glue doesnt stick well to some woods ?
I hear teak and cypress are great for rot resistance
I believe ash and hickory is what axe handles are made from
I have no idea which woods can be bent easily and otherwise
worked with real well.
In this day and age of super strength epoxies and varnishes
should we even worry about rot resistance since we can
waterproof the wood ?
