Remove the rotor frorn the tripods and lay it on the ground.Bring the portion of the rotor frame
that is completed up around it. Push the bottom shaft end piece as far down as it will go into its
bearing, which has just been mounted onto the support poles.
Assemble the top bearing mount and bearing loosely onto the top bearing support poles, in
approximate position.
Bring the top bearing support poles into position, straddling the vertical supports. Slide (tap
gently if necessary) the bearing over the top shaft end piece of the rotor as far as it will go.
Check these alignments:
*The rotor shaft should be parallel to the vertical support poles.
*The top bearing support poles should be parallel to the bottom bearing support poles.
*The plane of rotation of the top bearing should be perpendicular (at right angles) to the rotor
shaft.This also applies to the bottom bearing.
Mark, and then notch, the top bearing support poles and the vertical supports where they cross.
Fasten them together, maintaining all alignments. Tighten the top bearing to its mount and the
mount to the support poles.
Support the frame horizontally, with the rotor in it, on temporary supports high enough off the
ground so you can spin the rotor. The rotor must rotate freely in the bearings, without resistance.
Check all frame/rotor shaft/bearing mount alignments. You can make angular adjustments in the
bearing mounts by inserting good-sized, sturdy shims. Loosen and retighten bolts and nuts as
