OPEN HOLE DOUBLE BALL JOINT What is an Open Hole Ball Joint? With the more highly machined joints, one would mill-machine Sockets into the metal plates and that is why they are called Ball & Socket Joints. With this simpler ball joint, the edges of the hole, grip & apply tension to the balls. Just study the photos and I think that you will be able to grasp the concept. In the beginning, I used this "open hole" socket method, but now, I mill-machine the sockets.There are some disadvantages to open hole, but for beginners or hobbyists, this jointing method should work okay in most cases. |
