Abstract: This invention relates to an indexer for providing rotation of a part from a first index position to a second index position. The indexer comprises an indexer frame and a part for rotation. The indexer frame has at least one index feature, and the part has at least one index feature, wherein the at least one index feature on the indexer frame is co-operable with the at least one index feature on the part so as to provide two or more index positions of the part with respect to the indexer frame. In use the part locates with the indexer frame so as to form an axis about which the part is able to rotate relative to the indexer frame, the axis being kinematically located.

Abstract: A billet holder comprising a base and a frame is described. The base and frame are connectable, and when connected are relatively moveable between an open configuration when a billet may be inserted or removed from the billet holder and, a closed configuration when a billet is retained within the billet holder. A billet for being retained within a billet holder, said billet having one or more orientation feature, is also described. The billet may have essentially a D-shape. Further described is a method of manufacture of an article from a billet.
