The plans look good. Thank you. What is Azek? I'm not familiar with that material. Does it float? Just a thought - I see that the boards are parallel to each other. What if we crank in on the threaded rod to put them slightly off to make them run harder to the outside? This way you could eliminate the SS bar.

Hay we are in the (R&D) Research & Development stages. Any ideas will be considered. ?????
