90º, and glancing blow from Earl?
Back aboard after using my home shop to create a solar panel mock-up I can use
to establish the correct geometry of the support frame above the bimini. It weighs half what a panel does, and I can drill and re-drill to my heart’s content should circumstances require.
Now to drill eight holes in the bimini bows. Each pair must be parallel and each location slants in both the x and y planes.
Funny how useful those high school drafting and shop classes are four+ decades later…
