About This Video:

I tested a fly wheel on the blower. Taking an old clay fly wheel from the pump drill I made many years ago, I attached it to the axle of the one way spinning blower to see how it would effect performance. The fly wheel tends to smooth out the speed of the fan and maintaining high speed despite taking longer to get up to speed initially. A smelt was conducted using the new set up and the result was less iron than usual due to the rotor coming out of the bearings at times. To fix this, the thrust bearings were replaced with journal bearings by carving holes all the way through the wooden stakes as opposed to only part way through. The new set up is more stable and has no chance of coming out during use.

Then, before the new set up could be tested, the monsoon season began and it rained nonstop for a week such that the hut had rain blowing in from its open sides making it impossible to make fire. A third wall was added to the hut made from fired bricks and clay mortar. A damaged section of roof was repaired with tiles salvaged from the old hut. Then I build a small water wheel that rolled up stream on wooden tracks to make use of the water. Looking forward I will probably do some water powered projects until the wet season eases.

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.
