Out in my garage in a big plastic box I've got a collection of fire boards and drills made from yucca that look just like those. Lots of yucca in the mountains and deserts here in Arizona. I learned about fire drills on the same outing that introduced me to muzzleloaders.
Nothing like the feel of adrenaline the very first time you're working the fire drill with both ends of the drill staying where you want them and the bow moving smooth back and forth and you see the first few whisps of smoke rising up from the fireboard. All at once you know your a real man
I'm looking forward to your videos.
Years ago I got tasked with demonstrating/teaching fire drills at a Scout Camporee. A scout troop came by every 15 minutes to see the show. Problem was there were 12 troops. My arm and shoulder were dead tired at the end, but I got a coal every time but the last. I was younger then. There's no way I could do that now.
Got one question. For the top end of the drill I was taught to use a flat rock that fits in the palm of your hand with a concave side for the drill end. (Even if you have to make the indentation in the rock yourself.) What do you use for the top end of the drill?
If you can't get the fire goin'
you'll still be warm from all the tryin'
