In the embedded video I go through some of the steps needed to create a triangular roofing board and supporting rafters for the organically-curved roof I'm "building" for my Yestermorrow practicum project. Please note that the boards I call joists are actually rafters. (My bad, but I think you will get the idea.)
Also please see the two images below the video. I've finished the hub placement. There is an end in sight!
