As it turns out I found someone to assist me, and once the dish was free, for two people it wasn't a problem getting it down to earth. We didn't drop it, that's the main thing.
It would have been tough to take it down in quadrants with just one person. The center plate is not held in place by carriage bolts, so you need a way to hold the bolt heads to keep them from spinning. A second set of hands is perfect for this when the reflector is on the ground.
I want to try coinmaster32's idea sometime, though. That's a cool idea. As for you, Kallesatman, loved the photos at your site.
