Primitive Technology: Water powered hammer (Monjolo) - (8:51)

1. Judul : Primitive Technology: Water powered hammer (Monjolo)
2. info : I built a water powered hammer called a “Monjolo” (see also karausu (からうす) on google images). I started by making a water spout from half a hollow log to direct water from the creek. This was set up in the creek and water flowed through it. The hammer was made from a fallen tree. I cut it to size by burning it at the points I wanted it cut (to save effort chopping). Next I carved a trough in one end to catch falling water. This was done first with a stone chisel that was then hafted to an L–shaped handle and used as an adze. This adze only took about an hour to make as I already had the chisel head and cordage made of bark fibre to bind it with. To save further effort carving I used hot coals from the fire to char the wood in the trough. I put the coals in using “chopsticks” (unused arrow shafts) to transfer them from the pit. The coals were fanned or blown with a wooden blowpipe till the wood in the trough burned. Then the char was scraped out. The sides of the trough were sealed with clay to make sure the wooden sides did not burn away which would effectively decrease the volume of the trough. This was approximately 8 hours work over two days. With the trough carved I made a hole in the middle of the log as a pivot point. Using the same char and scrape method I burnt a hole right through the log using hot coals and a blow pipe. Again clay was used to prevent wood burning where it was wanted. To burn through the approximately 25 cm diameter log it took about 4 hours and 30 minutes. Another hole was burnt in the end to fit the wooden hammer head and it took a similar amount of time. A tripod lashed with loya cane was set up at the water spout. The axel of the hammer was tied to one leg, the hammer fitted onto the axel and the other end of the axel tied to another leg. 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. This is the first machine I’ve built using primitive technology that produces work without human effort. Falling water replaces human calories to perform a repetitive task. A permanent set up usually has a shed protecting the hammer and materials from the weather while the trough end sits outside under the spout. This type of hammer is used to pulverise grain into flour and I thought I might use one to mill dry cassava chips into flour when the garden matures. This device has also been used to crush clay for porcelain production. A stone head might make it useful as a stamp mill for crushing ores to powder. It might pulp fibres for paper even.

39. Louis Sivo : Over this week I watched all your 26 videos. I'm in awe! Thank you for the education. Gosh, it seems so much easier in Minecraft and Ark. Yep, right there you should know I will be dead within a week of civilization falling. ;-) But as I go, I'll know you are out there surviving and will rebuild if it comes to that. But honestly, really interesting. You gave me an education and appreciation for what those who came long before had to do. I'd heard of many of the concepts, and the statements, "all you have to do to do X is Y..." so easy to say. But you showed all of us. I'll keep watching as long as you keep posting. Take it from this "Gilligan" you truly are the Professor! ;-)
40. 석현 임 : 왜 업로드가 안돼고 있죠 기다리다가 현기증날것같단 말이에여..ㅠㅠ
41. Droidman5910 : You should do water filtering with charcoal
42. Aleksandar Poznić : R U alive? Do something....
43. Glodomiro Gomes Barbosa : ótimo amigo sou escrito
44. Cyclone 180 : this guy should be on alone he would win no problem
45. Cyclone 180 : u were on the talking dead
46. African Jew : It would be dope if this channel slowly went through time with technology, since it started with small tools and basic shelters, and now its all the way to clay huts and simple heavy machinery, It might not be what the channel is about, but starting from scratch and using what he makes to make more and more complex stuff would be an interesting concept...
47. Vasilije jovic : i like the part where the hammer smashes the rock. So entertaining!
48. mún càng đẹp trai hơn : Đây đúng là 1 thằng lâm tặc chính cóng
49. Ross Lindeman : I want to see you hunt one of them turkeys and cook it
50. de Lucca-San : Make a Stone Hand Spinner.
