To start the process, silhouette type figures were cut out of hard wood using a scroll saw.
The blocks were then shaped with a Dremel rotary tool. Not exact, but close enough for whimsy. The figures are about 5" tall, and the faces about the size of a fingernail. Some parts were carved separately and either glued or pined in place. Dressmaker pins were were used for a lot of joints and mechanical connections. If some things look out of proportion it is because and artiest is licensed to exaggerate to attract attention to the work. There was a lot of preliminary fitting and testing as the work progressed, as can be seen in the above picture.
I prefer to not copy other people's work, but the Hula Hoop girl that I seen on You Tube was so unique that I had to bend my rules. All the rest of the figures of my own design. That was the most complicated figure, and it took 9 days to build.
The Hula girl is driven by gears, and I elected to make peg gears, because I think they are classic.
Motion is transmitted from the crank to the figures by cams, gears and pulleys. Here is a view into the mechanical compartment.
Finally after working at it doing something every day, 7 days a week for a month and a half it became a working machine yesterday afternoon.
