Today I made the base for my automata for The Royal Cornwall  museum. I kept it large as there are a lot of cams and levers to fit inside it and I don’t want to sacrifice movement due to lack of space. The cams are driven by a 24v synchronised 6 rmp motor geared down via pulleys to about 2 rpm. The automata will perform the following actions (I hope).
The Cornish giant will raise the Cornish flag above a large packing crate. When he lowers the flag a small faun will be revealed standing on the crate. The mummy will react with pleasure and raise and lower his tea cup three times. The Cornish giant may look up to the havens as if in thanks. The Cornish Giant will then raise the flag again, to conceal the faun, and when he lowers the flag the faun will have disappeared.
The packing case will have an arrangement of mirrors which will make it appear empty (a standard magic illusion) and the faun will disappear, via a concealed hole in the top of the packing case, and be hidden behind these mirrors.  PICT04111 (6)

This is the base for my automata. because it is made from wood it will expand and contract depending on humidity so I have to allow for this when I fit my cams and levers.

The drive pully. It has been turned on the lath and has a brass hub with a grub screw glued into its center.

The motor and drive pulley fitted to the ply mounting plate.
This pulley will be driven by the motor via a drive belt and will rotate the camshaft, turning the cams.

Here you can see the drive belt. It is industrial quality and is joined by simply melting the ends and holding them together.The resulting join is surprisingly strong

This lever will have a spring fitted and will push the brass rod up. The Faun will be attached to the top of this rod and so will be lifted out of the crate. I have fitted a piece of low friction plastic where the rod rests on the lever .

I have fixed the cam in place and the lever is being held against it by the long spring. The thin brass wire on the brass rod will stop it (and the faun) from rotating .The cam in the background will operate the mummy
