My first design was too small to catch enough wind, so I started making a larger sail. I planned to make a couple of right triangles on either side of a mast. The hinges will be at the bottom. When both sails are open, they will form an acute isosceles triangle. I planned some outlandish and overcomplicated joints, but I decided that a 1/4" (6 mm) bolt through some red oak would be a good starting place, and I could improve later if necessary.
Hinge for the booms
I connected fiberglass driveway markers with my square wooden dowels by drilling a 5/16" (8 mm) hole into the end and cutting a channel with a jigsaw. I cut as deep as a jobber-length drill bit for the moveable booms, but I used a particularly long bit for the mast.
Drilling for the mast
The outcome was a monstrously long mast. My wooden dowel was 41" (104 cm), and the driveway marker was 72" (183 cm) with approximately 8" (20 cm) of overlap. I added places for ropes to pass and cords to fasten along the wood portion, and I'll worry about the sail next.
