Can't do much better than that, all you'll really need is to add a RA drive to really enjoy...

Beautiful! I'm considering a somewhat similar set-up built into the roof of an aircraft hangar. This requires an even taller pier than yours, about 20 ft tall. How did you spec your pier? What kind of foundation? Are you worried it might start to lean? How did you attach your mount to the pier?

Bob,

Thanks for the info. Did you ever consider an all-steel pipe pier? What made you go for a concrete pier? What did that pier with the engineering and all, roughly cost? Are there any good books on tall piers? So many questions, so little time!
