Step 7: Continue adding parts up the rod
Cut out three sails for your wind turbine to catch the wind. There’s no right answer here, and you have a few different slots in the sail holders, so just use scissors to cut the aluminum flashing in a length you think will work. Then cut 1/2 in tabs into each corner to slide into the slots. Bend over the tabs to secure the sails.
Do the same shaft collar, sail holder, shaft collar assembly on the top of the sail to finish this section of the build. It should spin with very little friction when you turn it by hand with the aluminum rod.
