After a troubled month of March, I'm making progress again.
I picked up all the pipe I need to make a tilt-up tower in February, and it's slowly been going together since. Using a scrap aluminum plate to align the holes, here's the windmill head under construction. I had trouble finding the right hole locations, because I built in a 5 degree incline to the hub's axis (for blade clearance).
I can tack-weld my stuff in my garage with the little gas welding set I own, but to finish I'll take it to the shop at work where it can be finished very quickly.
Before finishing, I mounted the rotor and stator - just loosely - to check one last time.
The blades are all ready, too - Almost there!!!
