Primitive Cord Drill Fire Sticks

Primitive Technologies: Creating Fire With Self Constructed Cord Drill And Pump Drill Fire Sticks.

Primitive Technology made a primitive cord drill and then upgraded it to a pump drill. A primitive cord drill is basically a spindle with a fly wheel attached so it looks like a spinning top. the middle of a piece of cord is then put into a notch at the top of the spindle. The ends of the cord are then wrapped around the spindle and then pulled quickly outwards causing the drill to spin. The momentum of the fly wheel causes the cord to wrap back around the spindle in the other direction. When it stops the cords are pulled outwards again and the primitive cord drill spins in the other direction.

He made the first one with a stone flywheel then made fire with it in the same way he made fire with fire sticks. Then he made and fired some clay fly wheels, made another drill with one of the fly wheels and fitted a stone drill bit to the end. This one he uses for drilling holes in wood.

He used the new drill to make a hole in a piece of wood. He then puts the spindle of the original cord drill through the hole in the wood, tied the ends of the cord onto the piece of wood and it became a pump drill. The cords were wrapped round the spindle as normal but now a pumping action of the wooden cross bar created the same action.

This was an interesting project. For fire making he recommends sticking to fire sticks because the equipment is easier to make. But for people with soft hands they could use the cord drill as it won’t give them blisters. It should be added that the pump drill actually took longer than the cord drill (cord: 32 seconds, pump 1 min 30 seconds – The pump drill scene was edited down to make it watchable). The pump drill had more moving parts and was constantly having problems. As a fire making method he recommends the cord drill over the pump drill unless all the parts were well made.

The main purpose he would suggest using these tool for is drilling holes rather than fire making. It was reasonably good but the stone bits he made could be improved and their attachment to the shaft also needs some thought. If the bit loosens and gets off axis slightly the whole thing wobbles. These drills are impressive inventions and show potential for carpentry use later on.
