Archive image from page 76 of Development of a spherical acrylic. Development of a spherical acrylic plastic pressure hull for hydrospace application . developmentofsph00stac Year: 1970 Figure 43. Jig for assembly of individual spherical pentagons into a 15-inch-diameter capsule. Large-scale capsules were also fabricated from undersize spherical pentagons, that when assembled allowed an joint space to exist between individual pentagons. Since the fabrication of an assembly jig for the large-scale capsule according to the same design that was used for the model scale capsule would have been expensive, a simpler jig was designed and built. The basic difference between the large-scale capsule jig and the model jig was that the large assembly jig permitted access for the shop per- sonnel to the interior of the hemisphere to make the taping of joints on the interior easier. The large-scale capsule was assembled and bonded like the models in three phases—the first two phases resulted in the assembly and bonding of pentagons into two hemispheres, while the third one culminated in the assembly of two hemispheres into a single sphere (Figures 46 through 50). 73
