Friction Drive

I now have an amazing book that explains movement so simplistically that even this non-engineer blogger can grasp concepts! To achieve the twirling movement described in an earlier post (see spinning top gif), it will be necessary to use a friction drive. The authors of Cabaret Mechanical Movement explain a friction drive allowing a change in the rotation of an object from vertical to horizontal (or the other way around) by making use of the friction between a vertical and a horizontal disc.

The two discs have to touch on the outer edge of the horizontal disc.

So simple, yet the twirling chicken will be fascinating to watch -- or so I hope!
