If you decide to work with green wood make them oversize so you can trim or reshape when seasoned .
To speed up the seasoning process I used the microwave (Use at your own risk) on the small ax handle with no cracking issues , the larger one went in the oven while the wife was baking (Use at your own risk) and had 2 small cracks at the bottom end of the handle that do not affect the handle .
Kepis's offer on a piece of ash is a great offer as ash works very well for handles .
The first handle I made ended up being too small but the second and third did the job .
Canada , more square miles of awesomeness per capita than anywhere else in the world !
