A Tiny Paper Machine

Here's a picture of the test gears from yesterday.


This morning I built paper versions of the gears that seem to work well. Folded tabs on the teeth of the gears help them to make better contact with each other.


I continued drawing out and cutting parts for the drawing machine. The parts ended up being really tiny. I would not want to go any smaller than this. The pin joints work well. I still need to revise the 90 degree sliding joint and the "T" joint to make them operate smoother.


The mechanism works as is, but it's a bit "fiddly." It draws only one portion of the curve. I think I would need to build more of the same mechanism in different configurations to complete the curve.
