Tiny little ball and it must be the worst to drive that thing as the driver sits almost on top of the engine, that will be a hot ride
Somewhat easy build so far, 3 18mm disks, 1 as main disk the other 2 cut into ribs and filled the space left with putty. As for but why did you not buy a balling or marble, well I did think of that but as gluing detail on steel or glass is a lot harder then putty I did not want to mess with that, wood was out as do to he wood grain, sure if I looked harder I would find a plastic ball but that would take be longer then making the ball like this.
