About This Video:
In the 6 years since I developed the first forge blower (https://youtu.be/VVV4xeWBIxE) I had made very few improvements to it"s design. So I decided to do some research and development to see if I could improve it"s efficiency. From my research, increasing the number of fan blades from 4 to 8 yielded an increase of 19% volume of airflow. So I set about building a better fan. Instead of splitting the rotor and inserting blades made of bark into it, I made spokes from split cane to hold the blades leaving the rotor intact. This increased the longevity of the rotor as well as the spokes being heavier contributing more momentum, assisting the impeller in winding back in the other direction after each rotation. Instead of bark being used to for the blades, simple (and easier to find) folded leaves formed the blades. These, being flexible, are less likely to break against the walls of the housing as stiff bark does. Finally, a lid was added to the housing to make maintenance easier. The new blower works better than the old one with more airflow occurring. I experimented with different numbers of blades on the impeller (4,6 and 8). The more blades used, the slower the impeller can be spun to produce the same airflow. This makes it easier to operate as the users arms don"t have to move as quickly, making it more ergonomic. This conservation of effort will be important in iron smelting later.
About Primitive Technology:
Primitive technology is a hobby where you build things in the wild completely from scratch using no modern tools or materials. These are the strict rules: If you want a fire, use a fire stick - An axe, pick up a stone and shape it - A hut, build one from trees, mud, rocks etc. The challenge is seeing how far you can go without utilizing modern technology. I do not live in the wild, but enjoy building shelter, tools, and more, only utilizing natural materials. To find specific videos, visit my playlist tab for building videos focused on pyrotechnology, shelter, weapons, food & agriculture, tools & machines, and weaving & fiber.

“Preparations for metallurgy” is the identical of the Surprise after credit scene!
You would possibly perchance perchance add a foot pedal to that drill half. When you defend a flat strip of wood and place a hole within the middle, then jog the stick half of the drill threw. Wrap the string one day of the stick, similar to potentialities are you’ll perchance perchance in most cases when using it. Then connect both side of the string to both side of the wood strip half.NOW potentialities are you’ll perchance look that if you push the wood strip down the stick, the strings will gallop it and twist one day of the assorted manner and get the wood strip motivate up the stick all any other time. Allowing you to actual defend pushing it down on a rhythm.So for those that prop up the fan half and lay a foot pedal on the wood strip half. Your foot can also attain the final work whereas you sit.Additionally a flywheel at the bottom of the drill will prolong the gallop of the gallop.
It feels similar to you’d like some manner to automate kinetic power. Treasure this blower, shall we embrace. All you'd if truth be told desire is some rotational power, ethical? Why now not admire a puny water wheel or one thing? That'd doubtlessly attain the trick.
Hello man! Been following you for few years now , colossal movies and colossal engineering there! One quiz tho, attain you ever obtain any injuries whereas crafting all these items?
Metallurgy – industrial 1.0 to 4.0. Excellent
Damn bro, this new minecraft model appears to be like fire.
The inlet hole in lid appears to be like relatively puny? Not definite for those that've examined in past?Great experience your travails
