I don’t really know how to make a 32 tooth gear out of wood. My robotics teacher advised me to try drawing it in auto-CAD, printing it, and then using the band saw to make more precise cuts. I will try this on Monday.

I would follow those links. Mathias Wandel is an innovator in the woodworking field and creates some crazy fixtures and machines using these wooden gears. I know that your gear needs to have a locking mechanism, but that’s something that we can work on.

Another thing to do would be to create a drawing in Inventor, draw the circle with diameter measurement for the gear and extrude it, draw one tooth for the gear and extrude it, then do a circular pattern (array) and space out 32 gears evenly over 360 degrees. if you still have space you can always change the number of teeth to close the gap.
