Re: [PSUBS-MAILIST] Stepped sail design .....opinions?



James. The hemisphere ends are pretty easy to find. There are lots of companies making them. Some are spun, but most are pressed. You can get them up to 6 inches thick.
I got my tubs from Fort Worth F&D Head Co. in Texas for $1000 each. 84 inch dia. X 3/8 thick but they are semi-eliptical, not hemisphere.
Go to their site and take a look.
