IM thinking of incorporating a furling device on a mill im trying to have flying before bad weather. I have read Gizmos link on furling . Today I went out with g clamps round stock,some pipe, and light angle iron. I clamped the 5/8's bar stock to the side of my mount at about 20 degrees then slid the pipe down over it then clamped a piece of angle to it and a piece of flat stock to simulate the tail.Now when I rotate my pivot mount and hold the tail some what in the same direction it was in I can see how things change! This made the furling project a lot more understandable and I can see the need for tweaking the tail weight etc.'  '
This turbine will have clock wise blades , which side should I put the ofset furl, or dose it make any difference which side its on?'  '
I have a 1931 Airmotor motor and the tail furl has a big spring and rod and also activates a band brake. the blade is 98 inches dia the offset between the tail and rotor is 5.5 inches the tail is 49 inches long and has 42 inches between the mill and tail fin. the fin at the widest point is 38 inch and tapers down to 20 inches.just some extra information URL=http://www.motherearthnews.com/Renewable-Energy/1973-11- 01/The-Plowboy-Interview.aspx>The Plowboy Interview[/URL> |

Yes We have some pictures but Ill have to have Bub post as I dont think I can do that with this computer. The motor top section of tower and blade are on the ground and have been there a while. The man I got it from bought it new in 1931 and it has angle iron legs 4-5 feet long and it was on top of a earlier wooden frame tower!He burned the tower '  '. I have another complete mill and tower on a trailer and I think it also is a Airmotor but will have to wait til some leaves gets off the brush so I can get up to it. I had the Idea that I could make a working mill out of the parts of the two.
I have been thinking lately of converting the tower to a wind generator tower. URL=http://www.motherearthnews.com/Renewable-Energy/1973-11- 01/The-Plowboy-Interview.aspx>The Plowboy Interview[/URL> |

Looking at the top picture you see the tail mount and furling device on the right side. On the left side you see a cast hub this is the back side of the blade shaft housing and at the bottom is the pivot shaft. if you look to the far lift and down towards the ground you can just see a bit of the break drum and band. The distance from the tail mount to rotor center is 5 1/2 inches. offset roughly 2.3/4 inches each way. The bottom picture the small rods running down to the collar are part of the break actuator. the beakdrumand band can beseen a little more in the bottoom pic. The tail is up buy the house I had to take it off when I brought it home years ago. It was quite a load on a 1/2 ton pickup!! I don't know about Downunder but The Airmotor was quite popular in the states. You still see some sitting around old farms and the Amish buy and rebuild them.

isaiah Aeromotor units and parts are readily available, just google it. I sent Glen a link to a site in Missouri (I think) that deals in old windmills and restoration projects. I don't know where he put it; maybe he'll post it here somewhere in a reply. My grandfather had Aeromotors on his farm in central California when I was just a lad. I remember him pulling a chain that swung the tail to the side and stopped things from spinning. I think he had to climb up to reset it and maybe that's what that big nasty spring is all about, eh? At any rate, you should have no problem getting parts to restore at least one of the units. Looks like a sand-blaster might be something to think about buying or making first. Are you going to pump with your windmill or are you interested in making electricity? . . . . . Mac Nothing difficult is ever easy!

Guys, you are way off the money on this one, It is what i would call a windmill to country folk, better knowen on the forum as a water pumper. My second job in life was repairing these mills on site. Either you missunderstand what you have there or i missunderstood you were talking about a wind turbine. You quote 1931 model, well they are still being built here today and widely used in some areas of rural Australia. They would be next to useless to convert to a electrical system but very practical for pumping water. I see it kinda funny here as many farms have broken windmills and they have been replaced with solar pumps. And the rest of us are trying to make windmills to produce electricity, to pump water and the likes. Our fore fathers had it right with using wind to do the simple tasks. Pete. Sometimes it just works |

Sorry for the mistake in terminology. As kids we had a neighbor that was the WellMan (his son still is)and he used to install and repair these things and we called them windmills.In his later yrs he collected some and had 20 working mills on his farm at one time, but as time goes and generations lose interest some are now gone. About the only item we seen in this area for home made electricity was or is a Delco light plant or a Kohler generator . As for the one in the pictures it has been in this spot around 25 yrs. I may build one out of the two and make a water pumper unless I get a burning desire to convert the tower to a wind turbine. This is not top priority at this time. There were a couple of wind generators around but they were the 6 volt type. They looked like a old car generator. Well I hope this unconfuses's some.

isaiah That signature link still doesn't work. Use the fix I sent you in the PM. As for furling, here's a dandy link Gizmo sent me, explaining how it works: Furling Link . . . . .
