1. A method for manufacturing, the method comprising:
fitting together and datuming a beam and a node, wherein at least one of the beam or the node is formed with an aperture, and wherein a cylindrical interface is formed between the beam and node;
advancing a mechanical fastener through the aperture to temporarily hold the beam and the node in an engagement; injecting a structural adhesive into the cylindrical interface between the beam and the node; and
final joining the beam and the node by curing the structural adhesive,
wherein a surface of at least one of the beam or the node is formed with a first flow path and a second flow path, wherein the structural adhesive is injected in the form of a two-part adhesive including a first part and a second part, and wherein the method includes flowing the first part through the first flow path and the second part through the second flow path to mix the first part and the second part, wherein the mechanical fastener is formed with a first port and a second port, and wherein the method includes flowing the first part through the first port and the second part through the second port.
