I built my own homemade CNC router a few years ago and I’ve just barely scratched the surface of its capabilities. I knew Rick would have some interesting ideas of things to make with it. He was a little skeptical at first but once he got on board the ideas just started flowing. One of the first things he wanted to make was a homemade spirograph. Spirograph? OK, why not? Whatever gets him hooked. He bought a computer program that generates drawings of gears of any size. We figured we could use it make a set of interlocking gears to make the spirograph.
Step 1: Designing
I've included the g-code if you want to cut your own gears out. It's formatted for Mach 3.
Step 2: Cutting
You can see that I fiddled with the design a little to make it look like a bicycle sprocket.
Step 3: A Purpose
Molly stuck it under a glass.
Ah-ha! Gear coasters!
Step 4: The End
HEE! HEE! HEE!… Rick is completely hooked on CNC routers. Now we are in the process of designing and building him a CNC router of his own.
