Good news/bad news ... this is my tinker gen...( tomorrow it will tell me what I did wrong ( no I don't mount my gens mid-tower.. figure it out) ... good news.. my main gen online and cranking ( little bit worried about the 35 amp bridges since my logger is seeing over 40 amps throug it.. cross fingers)

sounds like you are asking for some broken PV modules. :-/

looks like it fell off the tower top and is dangling from the feed line??

That looks like a plate on the yaw bearing giving way and the genny slipping down the tower. If I'm right when you repair it heres a suggestion, make the yaw bearing pipe slighly smaller diameter than the tower so if this happens again it will only go as far as the join to the tower. If the welds broke on the yaw bearing plate time to get some practice welding.


 All in all it looks like Murghy stayed away and the genny didnt wreck those pv panels.

Actually this is a top mount, using a 1" pipe sleeved into a 1 1/2" tower pipe and through bolted. The yaw attachment is 2 back to back 1 3/8" flnage bearings. It looks like the through bolt gave way, allowing the 1" sleeve pipe to drop , which then worked its way out of the bearings.


FYI..we get snow here about once every 3 years...Norfolk, Va

Yes  you broke a blade and it's hanging by the power line through the tower, letus know if you recover the blade  and how far it went. I broke a blade once and found it weeks later

Actually the other blade is still attached by one bolt, you can't see it but its beside on of the others

For those of us without Xray vision, cropped too for under 640x480...  tsk.

That Nor'Easter storm will have whacked a few more mills before its out to sea.

Hope it's 100% salvageable!

Missing blades and dangling gennys aside, do you get decent output down there? I live about an hour north of you, in West point, and have been considering a wind project as it blows better here than it did in Chesapeake, but I don't know that I considered it ideal. Of course I was in suburbia, surrounded by many trees. I'm more or less on a river here, so I figured this was the difference... Any ideas?

The size of the project matters not.
How much magic smoke it contains does !

If you have tons of open space, maybe. Typically this is not a good area, but I live a couple of blocks from the beach and have an open marsh. I get decent power when winds are from the east side of north to south east. West or North West.. not so good

Well after getting her down and looking, the mill itself is fine. Looks like my through bolt sheared allowing the tower insert to fall, and the mill just kept bouncing on it until the insert came out of the bearings.
