I finished constructing a sturdy wooden cradle for the forward fuselage (see photo 1). With the help of a friend, I removed the fuselage from the rotisserie and placed into the cradle. The fuselage is now very stable and level, and the tail is still supported by the aft rotisserie fixture. This will make it easy to reattach the forward rotisserie when the time comes to flip everything over again.

I re-marked the centerline on the floor and reattached the gear plumb-bobs, then adjusted the left leg as required to get it parallel to the longitudinal axis. This required some more filing of the aft and inboard edges of the skin opening -- enough that I had to remove a skin rivet. The rivet hole now serves as a corner of the notch (see photo 3).

According the the drawings, the edges of the outboard attach block and the wear block have to be 3/16" inboard of the longeron vertex. I inserted a couple of drill bits through the two blocks (see photo 2) and tapped them inboard until they were the correct distance from the edge (see photos 2 & 3).

Tomorrow I'll tighten the large, 7/16" bolt/nut and drill the rest of the attach holes.
