I wish to have a real model photographed to put in my A4 too but as I went to the factory early this morning, there is not much progress done yet in terms of assembling ,at the moment the components are still in heavy parts. Plus accidentally found this interesting way to have free movements in the joints of the metal columns, by recycling the old steering wheel joint and modifying it to fit in each segment of the column. (imagine ball joint) by utilizing it i have more than 2 ways of rotation of the previous design of U-joint. From what i talked to you in the studio class on friday of having a Ping-Pong ball inside the 2 pieces, its the same idea, but the Ping-Pong ball is not strong enough to withstand the force and the ball inside has to be metal. My factory can make the metal ball that can fit into my design as what ever measurement thus it is very-time consuming,so it was kinda lucky that i found the old steeringwheel, otherwise the design might have to change back to the previous one. The u-joint allows users to interact in only 2-Dimension while the ball joint in 3-Dimension, and this is what we want.
