The driver arrived with my wheels at lunchtime and I wasted no time opening the boxes and trying them out. They roll extremely easily and seem well made. Probably complete overkill but I'm not getting any younger. So I don't want to be struggling to turn the dome later on. You never know how much additional weight might be necessary for water-proofing.
The inevitable, freshly unpacked shot of the gorgeous wheels: Swede Wheel | 5PF 160-PA6 R

The cladding on the tall pier is cheap, flooring grade, crap plywood.
The Red oaks are still looking colourful.
The forecast is wet overnight but much brighter tomorrow. I have decided to take down the mounting to remove the obstacle to base ring accuracy. Two stepladders will have to be lifted up there, straightened, then tied together with the chain hoist.
I'll leave the mounting on the obs. floor well wrapped up. Then I can measure assorted diameters of the ring for the wheels. Once the wheel track is confirmed I can decide whether to replace the mounting.
Fixing the eight, timber brackets for the 2x8 octagon, wheel support ring will take another couple of hours. I'd better get cracking while it's still dry weather.
