Everyone’s favorite survival YouTube channel is back with another awesome tutorial video.
YouTuber Primitive Technology started off with a simple cord drill and he then upgraded it to a pump drill. A cord drill is basically a spindle with a fly wheel attached so it looks like a top. To get it spinning you need to pull both strings as the same time. The momentum from the stone flywheel causes the cord to wrap back around the spindle and then the process is repeated. What’s unique about the final pump drill is that a single piece of wood is attached to both ends of the cord, which allows a user to operate it with an even simpler pumping motion.
We can’t wait for Primitive Technology’s next survival tutorial.
