I have two sawhorses. On each of these I have a 1" X
4" X12" piece of wood, covered with carpet, attached perpendicular to
the middle of the sawhorse with a large hinge. The hinge is attached with a
large bolt to the sawhorse which permits it to pivot. The sawhorse is
placed under the wing with the wood piece running along and under the spar
outboard of the join. The hinge allows the wood piece to accomodate the wing's
dihedral and the change that takes place when one wing and then the other is
lifted, changing its angle to the sawhorse. The pivot on the hinge-sawhorse
interface allows the wood piece to pivot as the fuselage is pivoted in
pitch to lift the nosewheel. I crawl under the outboard portion of the wing with
the sawhorse near the leading edge. I lift the wing by arching my back and slide
the sawhorse into place. Then I crawl under the opposite wing and do the same.
If the first sawhorse is placed too far inboard, it will put more load to
lift on the opposite wing.
