elbows

The elbow is the region between the upper and lower parts of the arm that surrounds the elbow joint. The elbow includes prominent landmarks such as the olecranon, the elbow pit, and the lateral and the medial epicondyles of the humerus. The elbow joint is a hinge joint between the upper arm and the forearm; more specifically between the humerus in the upper arm and the radius and ulna in the forearm which allows the forearm and hand to be moved towards and away from the body.The term elbow is specifically used for humans and other primates, and in other vertebrates forelimb plus joint is used.The name for the elbow in Latin is cubitus, and so the word cubital is used in some elbow-related terms, as in cubital nodes for example.

    Bsp brass elbows going into brass mixer. Seating of the elbows?

    See photos attached. The issue is that when the elbows are aligned up in the direction they need to go, they are loose, not seated. How is this resolved? Is there some kind of brass washer I can put in to take up the turns? Any guidance appreciated. Thanks.
