It is hindged, and the counter balance is where on the pipe the hindge is bolted. This is somewhat complicated by the threaded connectors but worked out ok. The cinder blocks were up as a counter balance for the backhoe to gently place it at the top of the 20' tower. With windmill up, it's about 50lbs bottom heavy (or there abouts). There is a small boat winch on the cable to raise and lower it.
Tower was bought used, kind of broken up and dented. It was for an amature radio antenna, but fell in some storm. It is 3" Galv pipe with threaded connector. It also has some welded strait iron to prevent the bend. And yes, I can raise and lower the tower alone. Takes about 10min if the turnbuckles are not stuck.
here is another picture of the hindge.
One other change different from Hughs design was how I keep the windmill on the tower. I used a large 5" washer from a seat belt anchor and some scrap I had around to hold the assemble to the tower. Basically same for the tail (not shown).
This is the most posting I've done all summer, but I'm glad to share it.
I hope I've not made the pictures to large.
I'm already thinking about my next windmill and I can't wait to see the Dan's new thing up front.
thanks again
