Parts cut out for Quiet Contemplation of a Sandwich, ready for finishing and fitting.




Birch ply used for strength in intricate parts .
Beech used for strength in small parts an weight in counter weight parts.
Premium pine for frame, dovetailed for strength and trueness
Cherry for crank handle because I like the wood.
Yew used for handle for colour and smooth finish .
Lime used for carved parts for detail and ceramic like finish.

Dovetailing of frame.



The frame is joined with dovetail joints. The dovetails take time to cut but are worth the effort as they form a strong joint even without glue and allow the frame to be assembled and dissembled during construction of the automaton.

Pin and toothed cog gearing from automaton in construction.


Gears are made from pins wheels driving geared cogs. They would not work in a food mixer but are beautifully reliable on a wooden automaton.
Pin wheels can also be used as cams to save space.

Cams and followers from automaton in construction.



Cams hold information like the grooves on a gramophone record. Hinged cam followers are used and they act like the stylus on a record player, accurately reading the information on the cam with no tendency to stick. The followers drive either linkages or push-rods.
The cogs are large to make the mechanism robust but when fitted into as small a space as possible makes the mechanism a fascinating part of the piece.
