Making a wooden zoetrope with right angle gears - Animation toy
















Special thanks for the inspiration and info to Mathias Wandel: Right angle gears video
I also wan to thank Peter Brown for his inspirational video.
Tools and materials I propose: Lathe

This is a classic vintage animation toy. I just made my version of it, out of bass wood and plywood. 

After making a rough but working prototype, it was time to make the final version of the project.

I set the fence of my table saw at the correct width and cut my plywood pieces to size. For the cross cuts I used my cross cut sled.

The gear box would be joined with half lap joints. I created them on my table saw. I set a stop block on my cross cut sled and did a series of passes to create the grooves. I sanded a little bit with a sanding block.

To make the gears I created templates based on Mathias Wandel’s gear generator. Mathias has also made many tutorials on making wooden gears so I followed his instructions quite a bit.

I added tape on the plywood and then glued the templates on the tape with spray adhesive. This would help me remove the templates easily, once I was done. At this point I marked the centers of the gears and removed most of the material on the bandsaw.

To cut the bevels of the gears I made a new base for my bandsaw that has 14 degrees angle. I cut half of the bevels. The blue lines of my templates. Then I flipped the base over and cut the mirrored bevels ( the red ones). I sanded with a popsicle stick which had sandpaper glued on it with double sided tape.

At this point I glued and nailed the gear box  sides together. Using a wet rag I wiped off the excess glue. 

I made a few holes with the drill. 

The gears are glued on 6mm dowels. 

Using a hole saw, I made some spacers. On the bandsaw I made relief cuts, so I can remove the spacers easily if I have to. The spacers are fixed in place with a screw. 

I added a spacer and two washers to each gear. At this point the gears worked nicely.

I made a handle which I shaped on my belt sander.

I filled the nail holes and sanded everything smooth with my random orbit sander.

Following Mathias advice I varnished everything so the gears wood work a bit smoother. I used clear water based varnish.

The top piece was made out of basswood. I had to glue two pieces together, so I first flattened them on the jointer - planer machine.

I then glued the pieces together. Once the glue was dry, I squared my stock on the jointer and table saw.

At this point I drew my guide lines and cut my grooves on the table saw. For the diagonal grooves I made a simple 45 degree jig so I could hold the piece on my cross cut sled.

This worked out and I mounted the piece on my lathe using a face plate. 

I shaped the top with the bowl gouge. I only used a flat chisel as a scraper to clear it’s bottom corners. 

During the assembly I added my wax and oil paste to all the meeting surfaces. Then I assembled all the parts together. 

The grooves were too large for the animation effect to happen so I made a paper insert for the top with smaller slots. Perhaps in future I will remake the top.

Then I added my animation inside the top and started playing.

This project was more difficult than I originally thought. But it worked out in the end. 

I hope you liked this one, because that was it. See you soon with a new project video.
