This piece has gone through several revisions. The one above is a custom made version with a carved lime wood head. The bottom one, below was the first version and the version immediately below I made as a piece that can be reliably made without carving to enable me to make a plan.
The plan is available on the plans page.
This was the first piece that I made and the set up forms the base of most of my other designs.
Plans are available for £9.99. They are a good base for making many other automata.
