      Actually figured out that using the slider hinge worked somewhat for what I needed. However what Physicsguy said. I'm not sure how to make the boxes moveable (I'd like to put an axle in the middle and have all the box frames rotate, with the spheres still being trapped inside, yet able to roll. (I'm experimenting with perpetual motion idea's I've had for nearly 20 years.)

        If you noticed, the frame looks like it is made of four boxes. just turn those boxes you see into components.

          Changing them into components did not do anything different. Attached hinge, nothing, attached motor, nothing. (Yes I linked them up right to the appropriate parts) However, having those set as static mesh. unset static mesh and the cylinders fall straight through the box frames.

            Could you post the model. You can try scaling everything up.

              This is going sound weird, but How do I post a model. Post it here? On google 3d warehouse?

                      All the boxes have to be a separate group.

                        Aha! When the physics are edited, the 4 parts are changed to BOX physics, Then grouped. I was making them static mesh, which was wrong for what I needed them to do.

                        Thanks for trying to help here phy!
