Hello, the only pictures I have are already included at the end of my video. So, if you want to visualise some pictures, just stop the video. For the Lego constructions, I provide a construction plan because the number of pieces is small and the pieces are all standard one's. For the Fischertechnik models it makes no sense to provide a plan. Because you will not have all the pieces. Just try to understand the principle of the mechanism and build it with your available pieces. You can use 2 plastic cups as a chain recipient. I wish you much building pleasure. Engineer Jack
