My attempt to test one of Mr. Hall Gravity Wheels, video

Nicely built!
I am sure it will never work, but one could argue in the following way (just for fun, thinking like a OU freak):
- The three moving rods (dark wood) have to be heavier in oder to overcome the rolling friction of the wheels (pale wood). One could add steel nuts or washers over the rods, or one could use steel rods.
- The two wheels could be made from thinner wood to loose weight.
- The diameter of the two wheels (and with that the lenght of the three moving rods) could be greater to reduce rolling friction (and to allow for heavier moving rods).
Again, I would not bet my money on these ideas. But OU machines always have to be bult a little bit bigger and a little bit differently in order to work.
