I like the detail of the bird perched on the trail spar of the generator. Great work.

@1foxtrot70 Thanks for the comment. The tail portraits a male black grouse.

thanks for the info, i forgot to ask what does your turbine swivel on?

[ratburger12345]

The yaw bearing is the rear spindle bearing from a saab 90 passenger car, tapered ball bearing. The other rear bearing from the car is the main bearing, on which the rotor and generator rotates.

I'm planning to change the yaw mount later this spring to a pipe ower pipe assembly. The reason for this is that the tapered ball bearing spins too easily, making the turbine hunt around a lot in turbulent wind days.

how did you ren the cables down from the generator how did you stop them from getting tangled??????

[ratburger12345]

I use a rubber cable to bring power down from the generator. It runs inside the metal extension pipe on top of the tower, and on the wooden part on the side of the tower. The rubber cable twists with the mill. So far the worst it has had was 3 turns of twist on the cable, it seems to untwist itself naturally.

Tuolla ladataan saunamökin akkuja. Ihan harrastusprojektina tämän olen rakentanut.
