I’ve been working on the mechanical parts of the toy this week. I built a 10” x 10” box with mitered corners out of oak. The back drop and other pieces are out of poplar and the stage is 1/4” birch. I used 3/4” birch plywood for the gears and collars and cams with dowels for the different rods and pistons.
The back drop will be doweled and glued in place, and I am trying to decide if I want to put the title up there or down on the oak. All the other pieces will have screws or pins, so that it can be disassembled for adjustments or repairs. It is necessary to shim and adjust things a bit, in order to get him to dance properly. The boots have to hit the pkatform just right to get him to kick his feet out.
The piston is just a dowel rounded on the bottom and running through a hole drilled in the cross bar. The tooths/cogs on the wheel push it up and down, transferring that motion to the lever supporting the figure. I’ll sand and pretty things up a bit when i have it tweaked a bit more. I am working on a second figure, a dog, that will be sitting by the first and will be moved by some arrangement or another. It’ll have feet of some type to raise it up for the crank to clear. Thanks for looking!
