Yeah, this is not something that's gonna turn out much if
any power, and I'll more likely make a speed change (if I
do one) by using an electric drill body with its planetaty gear.

Why does a person buy a Prius with gas prices low? They
are wanting to make a statement of agreement to the prospect
of being environmentally frugal. That's what this project is, so
I'm not willing to put a lot of bucks into it. Besides, the mean
annual power per square meter at 50 meters for my area is
less than 100 watts. I'm sitting on the ground. I mainly want
something that will turn when wind speed is minimal. So it's
turning when my neighbor's is not. I can deal with making
power as the process moves along, not buying neodymium
magnets any time soon.

What do you have for a workshop?

I tried for years to make power transmission equipment with
woodworking tools and only achieved 18th century inefficiency, high
maintenance and rapid wear.

The practical minimum seems to be a 9" or 10" thread-cutting metal
lathe and a mill-drill, though a knee mill is better. If you buy a
horizontal mill you also need a good drill press. Decent machines
should appreciate in value so they can be considered an investment
rather than an expense.

The 3000 to 200 RPM transmission using mostly new parts cost me close
to $00. It was sized for 10HP but a smaller one wouldn't have cost
much less unless I used old washer or dryer components.

Considering all that, why not skip the gearing and just build a large diameter
60 pole generator into the large base wheel. With enough windings on each coil,
you should be able to develop some power, maybe even enough to load it down to

Is there a suggestion of number of turns per coil? I have a
pound of #20 magnet wire.

For a 60 pole generator, you're gonna' need about 25 pounds of that wire.
