Yaw bearing

[jmk]

 I polished the the tower top and the inside of the yaw pipe so it would fit on with no play. I cut a 1" piece of yaw pipe and welded it to the tower, so when sliding the yaw pipe on it will stop when it hits the collar. I put a grease fitting in the yaw pipe. The tower goes all the way trough, and then sticks up about 11/2". The part that sticks up I drilled and taped a set screw. I am putting the tower on a big mogal of a hill, and it may lean down hill a bit. I didn't want the turbine to fall of. I cut anouther piece of yaw pipe 11/2" and welded it to the top of the yaw bearing with about 11/2" gap inbetween. This will leave room for the head of the set screw. Above that I plan on puting a removeable aluminum funel to route the wires down. Will this work? What are your opinions?

Your generator looks really good. One think that you mentioned that your tower will not be totally vertical, that will be a problem. Your mill will not face into the wind and even if it will it won't furl properly. Having the pivot bearing on the bottom shouldn't be a problem I though IMO.

What is the diameter of your magnet rotor and what diameter are your blades?

Keep up the good work.

Forget the question, I should have looked at your other post.

 It will stand plumb when it is up. When I tilt it down to the ground I was first thinking it would be laying down hill. Now I think the hill will be ok if I tilt it down and stop when it is level. This will leave the rotor about 8' in the air. This way the blades and tail wont touch the ground. I am still glad I put the set screw in. I think the collar at the bottom will help hold the grease in. I wonder if I put wax at the bottom if it will even hold the grease in better?
