Hi Adam,
I managed to figure it out, there is 2 steel tapes one is connected to one side of the radius and the other connected to the other side on the wood. The other steel tape is connected in the reverse. It is quite ingenious actually as it would reduce noise transferred from the motor more than direct gears.
The piano wire method is only similar in concept, still may work though but I like the steel tape idea. You adjust the thickness of the steel tape depending on the weight you wish to load on the system.
