- Slip the upper rotor blade assembly onto the rotor shaft. The underside of the assembly should be approximately 3/8 inch above the washer. Bend the top of the shaft over the blade assembly as shown. Use needle-nosed pliers to squeeze the wire, clamping the rotor blade assembly securly in place.
- Cut a 20-inch piece of rubber stripping. Fold the stripping in half so its thickness is doubled, then install as shown, trimming the ends to a point to make it easier to threade them through the holes in the bottom of the frame. Adjust the stripping so that there is just enough tension to hold the rotor shaft upright. Tie in place with a square knot at the bottom of the frame.
- Check to see that the rotor assembly is aligned as shown. Rotate to see that it stays in alignment as it turns. When satisfied, apply a drop of super glue to the top and bottom of the rotor assembly to attach it permanently to the shaft.
