I saw this automaton on a YouTube video done by Ben Brandt, and I had to make one for myself.
I put the design into Google Sketchup.
The entire assembly is built of common pine.
There is a total of 4 cams….....
1. lift arm and hammer
2. lift nail
3. rotate head right
4. rotate head left
It takes the carpenter 3 blows to drive the nail. After the 3rd blow, the hammer rises quickly back to the up position, while the nail takes a while to slowly raise back up into the original position. It took me a few trials to get the cam designs right to do this.
The neat part is seeing this carpenter in action, which you can by viewing the YouTube video I made of my model.
To see my trials and tribulations of building this automaton, see my woodworking web site.
Have a Merry Christmas
