Cutting planks for shipbuilding circa 1600s before steam power there was always wind power. Nothing to do with model engines but thought you might enjoy this clip anyway.

That is way too cool.
Thanks for sharing that.

That is cool!!

There are no old wind mill powered mills around here but there are remains of water
powered saw mills and gristmills.

They must have been similar to this one in there day.

Good post, thanks!

My wife is the bookkeeper for a 100 year old animal feed mill here in Punxsutawney.

Today they mill specialty feeds with a diesel powered hammer mill, but the old water
driven gristmill building is still standing.

The yellow circle in that picture highlights the stone and concrete water trough that runs under
the building. It channeled water under a large water wheel inside the building that turned
the mill stones.

I'd love to get into that building to see what remains of the original equipment.
Maybe I will someday.

holland used to be stuffed with them. now just few remaining, and even less in working order. enabled us to build good ships that sailed the world.

Thanks for starting the thread Herbiev!

This wind mill powered machinery is great!
It is something I have never really thought about.

Can anyone explain the fly ball governor action on this one?

I think it feathers the blades. ??? ??? ???

In the UK the centrifugal governors were fitted after about 1780 to automatically control the gap between the runner and the bedstones (the top moving and the bottom fixed grinding stones) when milling corn. You can see each of the three governors on this drawing.

The speed of the sweeps are controlled by the skill of the miller adjusting them.

On water mills governors were used to control the water flow. On this drawing you will see the governor being used to adjust the sluice gate:

Following that logic I would guess on a sawmill it will be controlling the advancement of the wood on the blade using the ratchet we saw on the video.

I suppose I could go and ask them, it's about 2 miles from me.

Never seen it working for real.
