Now theres your problem!

  I took the blades off before I brought down the motor. More trips up and down the pole but less weight to deal with when doing my little ballancing act on a slick steep metal roof.

  I later went back in the shop to put up some stuff and I thought I would like to see if maybe the machine shop did their job wrong. I grabbed a coupple little jumpers and a 18v cordless drill battery. Hooked up and spun the motor and hub without the blades. The work the machine shop did was perfict. But the factory drilled blade bolt holes was weaving around.

  The manufacturer of the hub messed up. At least now I know where the problem is. I'll have to trim off some of the tips a little. They were off quite a bit, I would guess they wiggle in and out 3/32 to an eighth inch.

  I would box the thing up and send it back but I've had machine work done on it. Oh well, work with what ya got.

 It's hard to get a hub with that much in motion to make music without a couple of rebalance

  Hello Andy, my name is Kelly. Its nice to make your acquaintance. That shop out there just has a little flash contacting the house. It is 4x4 square tube on 6 legs. The enclosed part right next to the house where I have my shop has a 2x6 sq tube supported 6" concrete slab. Poured my slab in 2x6 forms welded to the shop legs. With a wrap of 2x6 sq tube arount as wall support at about 6 Ft up the wall.

  Well the house, its pier and beam. Kinda land isolated from the shop. Aside from that little flashing keeping water from running in. And its under an eave. Eaven with this outa line vibration I've had, There is no noise in the house.

  I threw a blade a coupple of weeks ago. Actually a hub failed. The hub on the one in my shop in the pictures. It failed in a 50MPH wind. It hit the top of the metal shed at crazy RPM and bounced into a tree. I diddnt hear it happen. Stuck my head out the door and diddnt hear the whistling it makes at good rpm. Just wind. It was treed.

 I've got a new billet aluminum hub I thought would be pristene, but I have had issues with it. I'm fixing to have things right, just a coupple more hoops to hump threw.

  Be cool man, good luck with your projects.
