Peter, it was 1hr 45 minutes. I carved it attached to the end of a piece, held in a vice, then once done, cut the teeth off and finished the back. Thanks for your interest !
I was about to fix the bit where the top and the bottom meet, but it looks like a cavity, so it was left as is.

Grandma - WIP
Grandma will be sitting behind grandpa, slightly to one side, just reading. It will be covered by a blanket, only the feet, hands and head will be visible. Hair, glasses and perhaps a glowing/smoking fag will be added later. The two bellows are also made, their purpose will be explained later.
Thanks for looking,
Gus

Grandpa Bending - WIP
Now that the majority of the character carving is more or less complete, started on the movement mechanics. Wanted to see if I could manage the bending without using external attachments, rods, links etc.
Cut a groove in the back of the right leg to accept a small diameter brass tube which would act as a conduit for a minute size stainless steel cable, bent the tube to follow the contour of the leg, glued it into place.

The front of the tube protrudes just under the belly, and is inserted into the torso, a small spring between the legs and the torso returns the stance to its upright position.

The wire is loaded into the tube, nicely moves around all the twists and turns. Here is a short video of the movement. Next will be the cam and follower to refine the movement.
Thanks for looking,
Gus

Grandpa WIP - movement mechanics
The movement control for this character seems to be working ok. The first part of the video shows the mechanics under the "stage". At the rear are two cams which contain the information for the movements. One controls the bend, the other the head turns. From the actuating arms, cable goes through the brass tubes embedded in the back of each leg, and is connected to the upper torso for the bend, and for the head, via a number of guiding eyelets to the bearing loaded dowel on which the head is installed. The white plastic arm under is attached to each end of the head cable which is twirled around the dowel, that is how the turns happen. All the mechanics is prototype, ( experimental )). When the whole thing is complete and working as wanted, it will all be remade (except the characters) to the wanted finishes/ standard.
Thanks for looking,
Regards,
Gus

WIP - Movements
Attached video is the progress of the scene so far. Cams which operate the movements, grandpa bending, turning the head, grandma reacting to his movements, and the gear train which rotates the camshaft. The speed reduction of this is 8:1. The "stage" shows the resulting movements. Further carvings to follow, and possible additional movements (provided I can figure out how) and the stage set following that.
Thank you for looking,
Gus
