The furling system with moving the rudder seems to be doing the job well. With regards to that, I had a trip out to the Chatham Islands many moons ago, where the locals had the old Gentle Annie washing machine motors as the power producer. Yes, it was a LONG time ago. Most of the wind installations had a furling system that simply tipped the generation head backwards, rather than sideways to the wind. Simply had a counter weight with the generation head on a universal joint above the pivot. Now there is probably a good reason that system I haven't seen, but can't picture why.

Hi Pete,

If you are asking about this type of furling then there are a few turbines that use that system, the whisper is one rotates up but at an angle as well. Another uses a gas strut, It works but there is always a downside and when it furls up it will cause a torque and want to turn sideways as it furls. In my opinion all furling is a very crude form of turbine regulation and safety but the alternatives are costly.

Thanks Phill. Gyroscopic procession must also happen with horizontal shifting out of wind as well. I don't have a mill of any sort, but follow this site with interest as all things mechanical crank my handle.

Just thinking that an adjustable counter weight may be simpler than getting spring tensions right. Can see that a rudder pulled 90deg will keep the mechanical bits sideways to the breeze if no energy is required from the mill. But that's what hot water elements and dump loads were developed for

Gday Pete,I have a horizontal furling tail on my turbine, well not horizontal, more like it furls out to the side and up about 25 degrees, I fitted a one way dampener, so it can not be slamed back down to its normal position by the wind after furling in a storm, seems to work well, stops the turbine from snapping its tail off ,, first turbine I made almost snapped its self off the pole , no dampener.. and the main mount for the turbine onto the pole was not strong enough , came home to see it rocking forwards n backwards with the wind , on top of the poll haha, have since learnt to over engineer them abit. Do you think you will build one?

Gidday flc1.
No not looking a building a mill, I live in suburbia. Hokitika. Booming metropolis with all 4,000 people spread over a wide area

where we do get a good sea breeze during the day, but in the middle of town it's not high on my list of things to do. Where about's are you located? My spare time (oh I wish I had more) is spent trying to keep current flying and projects in the shed. Closest I got, and the reason I found this site, was wiring a F&P motor for a mate who lives off grid and built a water wheel. Thanks to the information off this site, I got it right the first time round. Built a regulator, and the whole thing went great for about a year. One flood took the water wheel and generator 5 Km's down stream. New one built and installed and still going well.
Cheers

Gday Pete,sorry for late reply, I used to live in Hokitika, and Runanga, the coast rules aye. living in Opotiki at the moment, always love to go back to the coast anytime I can....Wish we were still living there,,,,,, maybe in the future, where was the water wheel ? which part of the coast?
