Dem Australier von Primitive Technology reichen offenbar seine schon großartigen Dächer, die er bisher immer aus Blättern gebaut hat, nicht mehr. So zeigt er hier, wer er mitten im Wald Dachziegel formt und die dann brennt. Wetterfest, würde ich meinen.

I built a tiled roof shed to provide a fire and rain proof shelter for working on projects during wet weather and for storing firewood. The shed houses the very kiln used to fire its own tiles.
I cut timber using the stone hatchet and took it to the building site. 6 Upright posts were stuck into the ground about half a meter. Mortices were cut into the horizontal beams using a stone chisel to start with, then had there mortices enlarged using hot coals and a blow pipe to burn them out more. These beams were put in place and rafters were lashed on with lawyer cane. The wood that the tiles sit on are about 50 cm apart. The finished frame was 2 x 2 m in floor plan, 2 m tall at the ridge line and 1.5 m tall at the sides. This roof angle is about 22.5 degrees, half the pitch of the huts I usually make. This took about a week but I did it about 4 months ago and left the wood at the site because I was busy on other videos.

Der Mann von Primitive Technology hat sich ein Schmiedebalg aus Ton gebaut und den anschließend sogar zu einem kleinen Schmiedeofen erweitert. Immer wieder beeindruckend.

Next, I made a rotary fan from two pieces of bark that slot together at right angles to each other to form a simple 4 bladed paddle wheel about 20 cm in diameter and 5 cm tall. The blades of the fan were not angled and were designed only to throw air outwards away from the axle when spun. The rotor of the fan was made by splitting a stick two ways so it formed 4 prongs. The fan was then inserted into the prongs and the end lashed to hold it in place. Spinning the fan rotor back and forth between the palms of the hands fanned the fire. But only some of the wind generated by the fan reached the fire. The rest of it was blowing in other directions, effectively being wasted.
So I built a fan housing from unfired clay to direct the air flow into the fire. This was basically an upturned pot with a hole in the top, a spout coming out of the side. The housing was about 25 cm wide and 8 cm tall. The hole in the top and the spout were both about 6 cm in diameter so that the air coming in roughly equalled the air coming out. The base of the fan rotor sat in a wooden socket placed in the ground to make it spin easier and the top of the rotor protruded from the hole in the top of the housing.
