Looking forward to seeing how you do the part where the diamond wires pass over the spreaders!
Are there any aerodynamic advantages to "foil shaped" spreaders compared to regular tubes, in real life?
As for the diamond wires, a notch cut in the ends and then two holes for SS safety wire to hold the diamond stay in place. The tip of each spreader has a block of ebony, which is very hard stuff and this spreads the compression load out over the hole surface of the spreader.
I do not have any numbers to support this, but I don't know how an airfoil shape could not have "aerodynamic advantages" over a round tube.
