The Tree Light Sprocket Spline Drive is constructed using a 3D drawing program in order to maximize strength and light weight out of 5/16” thick 7075 T6 aluminum. Unnecessary weight was removed from the Tree Light Sprocket Spline Drive by enlarging the holes and getting rid of unneeded material on the sprocket. The teeth have been patterned after industrial teeth to keep the drivetrain running smooth and quietly. The teeth on the Tree Light Sprocket Spline Drive sprocket have been made taller to keep the chain from derailing.
