Starting the joining of the fuselage sides. See how the fuselage is up side down and the forward section is flat on the building board. The top longeron
sticks forward and is pinned in place to keep alignment. There is a clothespin clamp holding the tail end together at this point., with pins
holding it over the centerline, and the two triangles in front also keep the sides accurately located over the plan. All the forward crossmembers
and the firewall are added at this point. After that the fuselage will be turned over on the plan so it rests on the flat lower longerons and all the remamining
crossmembers are installed, using the triangles as necessary to keep alignment over the centerline. Don't forget the tail skid mount bulkhead.
