Tell HN: Giving away my homebrew windmill

Hello HN.

After lugging it with me for a bit over a decade without ever having a good place to re-install it I’m giving away my windmill. It’s a 2.5 KW rated variable pitch machine that took over two years and a small fortune to build.

The project is documented here:

The machine definitely needs work, (1) the slipring assembly and tower shaft and mount will need to be re-made, (2) the whole thing could do with a new coat of paint.

It’s built with imperial hardware so you’ll need to buy some bolts to mount the blades. It is also heavy, you’ll need two people to lift it into the back of a vehicle. The blades are 2.5 meters long (three of them), the total machine is 5 meters in diameter when assembled. Some metalworking skills or access to someone who has those is a must. If you have a lathe that would make things much easier.

It goes without saying that this is a prototype machine and that installing and operating it is at your own risk, if you live in a city you are likely not going to be able to use it but if you have a remote cabin or something like that with steady wind this will give you power to spare.

Let me know if you are interested and able to pick it up near Hilversum, the Netherlands.
