Took apart bench back and the tube wrapped in aluminum foil stuck hard to the glass. It took me a while to get one of the backs (smaller one) free of the hinge tube. Will try to free the other back from the tube. Don't know if I can. I turned the plane around and removed the landing gear. Placed the fuselage on slides and leveled the plane (pitch and roll). Sanded the inside of the engine bulkhead and put the spar in and leveled the spar with the plumb laser level. Will glue the spar in tomorrow after I measure the tips of the spar from the nose.
