Staget 5:: Buildingil i thet Fuselages l
Initially, the fuselage will be assembled upside down on a special jig and then turned right way around and supported by two stands for completion. Refer to Figure 5/1 for the location of the fuselage construction jig parts (J008-J018). Check that all attachment edges are square and that all parts are aligned and square to the base as you glue the jig together. Taking the time to carefully prepare this jig will result in more successful assembly of the fuselage. The central, longitudinal section of the assembled jig extends below the crosspieces, against which the fuselage formers will be aligned. This slips into a slot formed by cutting part J019(WP———-) in half and gluing the resulting 300mm lengths to a baseboard that you supply. This same base will be used later for the fuse- lage support stands.

Fuselage formers; longerons; stringers:
Referring to full-size Plan D03, cut the four longerons to length from 5/64 x 5/64 wood strips(WP3673-24). Slip on the nine Fuselage formers(Ni28-037, 039, 040-046) in order, then turn this upside down and nestle it onto the fuse- lage construction jig. Clip the bulkheads against the forms and, without gluing anything yet, carefully check the align- ment. The rearmost former is simply a length of 1/8 x 1/8 wood(WP3631-24). Begin gluing from the rear by joining the rear end of two top and the two bottom longerons and then these to the tail frame, as in Figures 5/7 and 5/3. Where former #3 would go, glue in two lengths of WP3673-24 between the upper and lower longerons.
After the formers are firmly glued to the longerons, get out the bent pin again and bore holes through the formers #4 through #10 between the longerons. (See Figure 5/5.) Criss-cross the bracing wires (WP1205) through the holes in the formers alongside the longerons. Using the previously described weight tech- nique, secure the thread with glue at each former.
Glue the stringers, made from 1x1mm wood strips (WP3680-24), in place along the fuselage sides and bottom, connect-
ing formers #4 through #9.
Remove this sub- assembly from the construction jig and turn it right side up. Remove the construc- tion jig from the base and replace it with the support stand made from parts J020-023. With the fuselage sup- ported on the stand, attach false frames Ni28-053 and Ni28- 054, then glue on the rest of the stringers. Complete this step by attaching the braces, from WP3631-24 and WP3673-24, as indi- cated in Figures 5/6 and 5/7.
