Nice...if your going for heat...ide go with the thicker mags..the thin mags lose their stringht under a large load...due to the coil having a reverse field when they pass over the coil..coils..

My intention now is to make a well-arranged test stand and have, together with windmillfriends, a critical look at all components.

Yaw axle. The heavier the nacelle the more reinforcement sheets I would like to add.

As a side note:
How about shaping the lamination core out of disassembled transformer laminations?

The yaw bearing should turn less than 1 rpm. I could use this cordless screwdriver motor ( 180 rpm ) with one more reduction.

After mounting an extra planetary reduction of a cordless drill I have a good outgoing speed. 
But I think the torque is overdone, in fact the motor could be much smaller and it's too complicated this way.
I want to search for a smaller engine with the proper reduction.

As an aside relating to reply #796
I converted my electric powered ride on mower to a forklift like shape. The swing arm pivot of the power supply cable is attached to the top of the mast. Easier steering and riding around now.

No doubt you get a lot of second looks in that rig.

Actually I like this way of mowing because it brings less damage to the environment.
My big goal is to be able to mow with the energy of my, in cooperation with windmillfriends built, small windturbine.

I myself also would like to be involved in others who build a small mill.

The slide yaw bearing of reply #810  I would like to change to a double row ball bearing.
2 outer raceways turned / grinded in the hub.
