Abstract: A simplified hub and strut system for the construction and assembly of geodesic domes. The system is characterized by the outer faces of the hubs and struts being provided with recessed rabbets which function as shoulders for receiving flat nesting panels of transparent or opaque rigid sheet material comprising the outer skin of an assembled dome. The inner faces of the struts are desirably also provided with recessed rabbets to function as shoulders on which to seat interior panels of rigid sheet material. The system is also characterized by the use of aligning dowels to facilitate initial assembly of hubs and struts preliminary to fastening.

Abstract: A jig for the accurate and precise measurement of rigid sheet material for making panels for geodesic dome structures. The jig is intended for use in the assembly of geodesic domes of the type having a plurality of generally flat polygonal hub plates and interconnecting struts, each hub having a recessed panel-receiving rabbet in at least some of its edges and each strut having a recessed panel-receiving rabbet in its outer edges. The jig comprises three shoes, each adapted to engage the recessed rabbets of adjacent hubs of an assembled dome which, with their associated struts, define a triangular opening into which a panel is seated to enclose the dome. Each shoe has a length which is the same as the longitudinal back wall of the hub rabbet. The shoes are connected by three elongated bars, each extending between two of the shoes and adjustably fastened thereto.
