What I have been working on

For my next article in The Shed magazine, I have been designing and building this water wheel

water wheel-1 copyThe whole thing is about 1100mm high, and it can kick along at a fair rate of knots, even just with a hose as the water supply.

I’ve designed it to use either water weight (quantity, slow moving), as well as water velocity (smaller quantity, flowing at speed).

It has a square drive on one side of the shaft, so it can be used to do real work, and at some stage I’ll add some traditional gears to do just that.

    Nice work. It’s fun to revisit forgotten technologies and discover how effective they can be, isn’t it. It’s also a sobering reminder of how reliant our world has become on others making stuff for us, when you look at the skills required to make things like that and realise it was once commonplace, but no more.

    Guess I’ll need to dig out my box of Popular Mechanics from the 50’s and find a project that doesn’t use power tools, now that you’ve made me feel guilty!

    And here’s what you can do with a proper size water wheel:

    • Like it! Don’t think my little one would generate much, but that is a really satisfying way to become self-sufficient.
