Rotating Gear and Pinion

grabcad

I've built a rotating gear and pinion for my experiment. To ensure they turn in sync with each other, I wrote a custom script in AutoCAD. Now that's taken care of, both parts spin perfectly in line with their setting values. The basic layout is straightforward enough, but finding the right fit for the gears was where things got tricky.The video isn't mine; it served as my reference guide when designing this model.
