Primitive Technology: Cord drill and Pump drill

I made a cord drill and then upgraded it to a pump drill. A 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 drill spins in the other direction.
I made the first one with a stone flywheel then made fire with it in the same way I make fire with fire sticks. Then I 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 I use for drilling holes in wood.
I used the new drill to make a hole in a piece of wood. I then put 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 I'd stick 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 I'd choose the cord drill over the pump drill unless all the parts were well made.

The main purpose I'd use these tool for is drilling holes rather than fire making. It was reasonably good but the stone bits I 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.

I have no face book page. Beware of fake pages.

It's weird thinking of him sitting at a computer editing this

The look on my face when he first executed the cord drill was one of absolute astonishment. I've never seen anything so simply designed yet such a technological advance beyond it's palm-driven counterpart. Fantastic!

If there was nothing left but nature, this dude would totally survive

[RoofingConnecticut]

I love how he made this and now 6 years later he’s still palm driving sticks together to make his fires

[mygetrichslowplan]

I feel like I should paste all your descriptions into a word document, print it out, and laminate it in preparation for the end times. This shit could save my life, man.

You know what makes this channel great? No talking.

[hughjass]

A freakin' stone age drill, how cool is that, i'm sticking around this channel until this dude gets internet in a cave

[Jakeverhart]

Casually makes a power drill out of a stick and mud. I love this guy

[TheBrownLamb]

It's not only interesting to watch but almost therapeutic

[Jsims]

I love how each tool you make lays the foundation for a new and improved version. If this video was any longer i'm sure you would have ended with a forced air furnace and a lithium ion drill.

I had a "wilderness survival" class I took in college, and I'm now seeing why no one could get the cord drills to work and the instructors even brought lighters along to use instead- there was no fly wheel! We had to work in teams of two just to get the spindle to not fly out of the notch, and even then it was hard to keep it from doing that. My soft hands thank you for this video.

the sound's of nature are amazing

[JoshwaLaw]

Oh man I love the progression, from just two sticks to a drill and everything

[CommonCentrist]

This guy made me realize that I really need to get out more and do something with my life

[yeese]

Finally good content no click bait pure goodness

[Stein.Bagger]

Am i the only one who cant stop watching this?

[RameshShahi]

What I really loved about this video in particular, compared to the other survival bushcraft videos that are saturated over the internet, is that you explain the process, purpose and intent behind every action or inaction you made. A lot of the time I would watch a video pondering to myself why this person didn’t do what they did a different

mate you put all men to shame the things that you do are brilliant this is what should be taught in schools ..you have made my life better knowing that people give a shit about this place and work with it ..thank you ..respect in every way....
