I was recently at the Fort Union Living History event at the confluence of the Yellowstone and Missouri Rivers. I was scraping away on a bur oak (Quercus macrocarpa) stave while the tourists wandered through camp. I happened to be distracted a bit by a certain lovely Canadian gal, who shall remain nameless, and I ended up taking waaaay too much off the width of a handle.
The handle is now about 5/8ths of an inch wide and a little over an inch deep. There is nowhere near enough material to prevent flex in the handle and due to the wonderful character of this stave I really don't want to lose this fight. I have thought about building up the back and sides of the handle with sinew, or even glueing on thin layers of osage.
I may be getting old, but I am still young enough to learn new mistakes!
