Classic marble-lifter mechanism in wood

Here is a nice example of a common marble-lifting device sometimes used in marble track machines. It's cool to see how a few cams, sloped surfaces, and continuous rotary motion can be combined to make marbles climb stairs. This one was made and sent in by reader Richard Thorne.

Canoeing Man Wood Automaton



Here is a wood automaton of a man in a canoe by Stuart Chalmers. You can see that the mechanism is made up of just a crank shaft. It's hard to make out, but the crank arms are shaped like fish.

I very much like the use of contrasting woods for the mechanism and the box.

You can see a few other automata by Stuart Chalmers on his web site.
