I made some further adjustments, added details to the tweeter and so on. It looks good. Yes, to make this sail will be complicated and price. Not to mention that the thing will be over 6 feet long. I will not start doing it until I have the tweeter in my hands. I need to consult my machinist and see what he will suggest.  As I feel it all will boil down to the selection of metal. If it were steel then it will be thin, perhaps 3/8”, heavy like hell and welded. If it were aluminum then it might be 2-3”, bolted from top and bottom and disassembleable. The good part about aluminum that I could use a 4” sheet and CNC it to make 4” at the bottom and I would say 2” at it’s top. I might be very cool looking. The only thing that I do not know if aluminum-make threads in the bold will be able to handle the pressure of that lever atop. Well, we will see what the specialists say. There are other options – there is architectural plasmas – they are very strong, CNCable and could go the job but they are way more expensive. An aluminum leftover sheet of 4” that I need will cost in my local metal supply shop around $300-$400, though the architectural plasmas of the necessary strength will cost over a thousand dollars…. Anyhow, will see. The more people I talk about it the more I learn and the more options become available….
