Note: There are a number of ways to support the fuselage jig. Drawing No. 321 shows two
pipe supports, which will work. Our current thinking is that the best method is to support
the jig with a single post at the forward end and a “split post” at the aft end.
The post for the forward end should be located 350mm aft of the forward end of the jig.
This will place the post in the nose gear bay, aft of fuselage frame No. 2 and forward of
frame No. 3, providing room for the installation of the nose gear screwjack support. The
post should not be wider than a normal two-by-four (3.5”) so you will be able to retract the
nose gear with the wheel removed.
The “split post” at the aft end should be two two-by-fours bolted on each side of the box
beam jig. This will allow the bottom center longer to be installed between the two pieces.
The fuselage jig should be made so that W.L. 0 will be about 1280mm above the shop
floor. Since you will have to make a number of small adjustments to the height of the
fuselage jig to match it to the wing, you will need some method of making thise
adjustments. Two methods are shown in Figure 6. In addition, hardware stores sell floor
levelers which may by used.
