Hope you are well. I thought I'd share these photos with you illustrating the "Fork Hole" Bow Drill Method which was popularized in Mors Kochanski's 1987 book "Bushcraft."
I use this method occasionally when I'm out trekking in the mountains, and have always had great success with it. The trick is finding a forked branch that is close enough together to function as a notch for the burning powder to fall into while drilling.
For this particular set, I used a dead branch from a Sandbar Willow tree that was growing near a mountain stream. However, you can use just about any good bow drill wood for this technique as long as the fork is close enough together.
My bow was fashioned from an Aspen sapling, and the socket was carved from a piece of River Birch.
The spindle is Willow and was cut from the same branch as the hearth board. Contrary to popular myth, you are better off using a spindle and hearth board cut from the same piece of wood for best success. An exception to this rule is if you find a good piece of wood for your board, but the only decent wood you can find for your spindle is from another type of tree (Willow spindle and a Cottonwood board, for instance). Another exception is if you are in a part of the country where Yucca grows. Yucca spindles are truly exceptional and will produce a coal faster than just about any other wood out there.

I've used the exposed tang (AKA pommel) on the back of the Garberg's handle to pound on bark to make tinder bundles and cordage.
The Garberg's handle has proven quite comfortable even after carving several bow drill sets using River Birch, Box Elder Maple, Mountain Alder, Aspen, Willow, Cottonwood and Big Sage. The blade, though not a true Scandi-grind like Mora's classic bush knives, carves and notches well.
Mora also did a great job sharpening the back of the blade. It throws mondo firesteel sparks and has been excellent for scraping tinder.
Stay tuned for more!
