New project continued

I ended up using plastic fishing line, or trimmer line to be the joints. I melted the ends so the line wouldnt fall out. I know there has to be a better way but I dont know what anything is called so I cant look it up. I have to do more research. The hardest part is making everything go together without something getting stuck on some thing or falling out of something. Making gears out of popsicle sticks is not very precise. I'll try to get it going enough so I can post it here.
