More Primitive Technology: sandals, prawn traps, and water hammers

posted by Jason Kottke   Aug 14, 2017

It’s been awhile since I’ve looked in on what the proprietor of the Primitive Technology YouTube channel is up to. Over the past two years, this Australian man has built all sorts of tools, structures, and objects using only what he can find in the forest and has racked up over 330 million views on his silent videos demonstrating how he does it all.

One of his latest projects was building a water-powered hammer (video above).

The trough was positioned under the waterspout to collect water and the tripod adjusted so that the resting point of the hammer was horizontal (so water wouldn’t prematurely spill out of the trough).

The trough filled with water, outweighed the hammer head and tilted the hammer up into the air. The water then emptied out of the trough (now slanting downwards) and the hammer then slammed down onto an anvil stone returning to its original position. The cycle then repeated at the approximate rate of one strike every 10 seconds. The hammer crushes small soft types of stone like sandstone or ochre. I carved a bowl into the anvil stone so that it would collect the powder. I then crushed old pottery (useful as grog for new pots) and charcoal. Practically speaking, this hammer worked ok as a proof of concept but I might adjust it or make a new one with a larger trough and bigger hammer for heavy duty work.

He also made a trap for catching freshwater prawns:

And a pair of sandals:

He’s built up quite a following on Patreon as well, with people contributing over $5700 per video, putting him on a path to be able to make Primitive Technology his full-time job.
