Very little wind so far today but that gives me the chance to see how well the blades are balanced. They don't seem to favor any one stop position so I believe they are close. I want to adjust to fully furled under 25 MPH wind and it was great to see it happening yesterday around 20 MPH so I'm on the safe side for now and like it that way. I installed stainless tape for 2 feet on the leading edge of the blades. This really does protect from abrasion over time and it looks sharp when the sun is just right. With 3 coats of gloss enamel and a coat of good old car hard paste wax these blades really look super and I know from before the performance will be great. Dave Moller carves these blades here at :

My blades can get a bit out of balance and still not favor any certain position. I can tell by a slight wiggle in the tail, and a slight vibration on the tower. This usually happens after ice - snow. I am glade to see it all worked out.

I like to balance everything with it all together on the tower and know I can get it close, (no load of course) I do use the rear grease seal but remove the spring that tensions the rubber and also just slightly cut a bit of the lip of the seal to lessen the drag, I'm glad it's on there. On my previous I used low temp (snow mobile grease) which seemed to work well in sub zero temps. to help it start up a bit easier but at 18' I don't think I could have really known how much it helped. I have bronze bushings at the top of the yaw bearing and tail pivot that I hole saw cut from 1/2" plate to fit (ain't cheap) and are greased besides. After inspecting these from before I think they will last forever. Waiting on the wind, Dave B.

All I was trying to say was that after all you can do is done you can tell how well you did by looking at the tail and feeling the tower. I don't think that the dust cap thing matters after ten foot. I greased mine booth ways and couldn't tell the difference. If there is it isn't worth worrying about, so you might just as well grease it. To tell you the truth the balance changes with the weather. You have experienced more than I with wind turbines anyway. I am just trying to give my two cents. You are well on your way.
