And, as suggested above, most urban areas offer both water-jet and laser cutting services, you can usually have the stock delivered directly to the shop, so no need to haul a dozen sheets of ply on the roof of the car.......

The base ring with the extra spacer blocks (doubled the number). I just have to fasten them on this side as the battery in the cordless pooped out.

The main inner slit arcs are rough cut and ready for the router table. Once these are done there are two inner and much thinner slit arcs to make. Then the focus will turn the the arcs for the sides.
So far the plywood sheet tally is at two sheets. The left over piece is that curved piece (upper right) in the second photo which should make a couple of the thinner arcs. I am pleased with the wood use and scraps. The waste is very little. Spacers were made from little scrap bits I had floating around but if you had to buy a 2x4...one piece would do them all. I am keeping a cost tally and spreadsheet of materials bought/used. I will post a final tally of cost and materials when completed.
Now the construction is going to take a more vertical approach. Should start looking like dome soon!
