A tooling assembly for a lathe machine includes a tool platform configured to be mounted on the lathe machine, a milling tool holder fixedly secured to the tool platform and workable to releasably secure a thread milling tool therein, and a milling tool drive. The milling tool drive is operatively connected to the milling tool holder and operable to rotate the milling tool holder independently of a work holder to mill threads on the workpiece when a pipe thread milling tool is secured in the milling tool holder. Computer numerical control threading lathes and methods of milling threads in tubular workpieces are also described.

An example tool-support apparatus includes a frame having a first support member, a second support member, a third support member, and a fourth support member; a first host-mating plate affixed to the first support member; a second host-mating plate affixed to the second support member; a first stabilizer affixed to the third support member; a second stabilizer affixed to the fourth support member; a first rail extending between the first support member and the third support member; a second rail extending between the second support member and the fourth support member; and a tool support member having a first end slidably coupled to the first rail and having a second end slidably coupled to the second rail.

A spar structure for connecting a moveable component to an aircraft includes a continuous body of material defining a plurality of attachment and actuation brackets. The spar structure includes a pair of continuous hinge lines extending through the body. The spar structure is formed by drilling a pair of elongate bores into a block or billet of material to define the pair of continuous hinge lines and by machining the block or billet of material according to a predetermined machining profile to form the spar structure around the pair of continuous hinge lines.
