Unable to duplicate Spur gear example in Video Part 2.

I've been carefully studying your four intro youtube videos about the Ticker program. And decided I should be able to duplicate some of the examples that you demonstrate.
The very first example in Part 2, illustrates two spur gears . I have been unable to duplicate the examples demonstrated in the first 7 minutes of the video. I created two spur gears with module 2.0: a wheel with 20 teeth, and pinion with 10 teeth. I added a motor to the wheel and then tried to simulate the motion. Only the wheel turns and not the pinion. The teeth of the wheel pass through the teeth of the pinion. This is true whether or not the simulation option of Collisions active is selected or not.
What's interesting is that the video shows Wall gravity on and gravity on, collisions not enabled and yet the Wheel drives the pinion. As I followed the video up to minute 7, I did notice that the gears in the video had position locks turned on. I tried the case where I unlocked the position of the pinion and started the simulation. Rather than swinging down as in the video, my pinion simply dropped off the screen.
Somewhere in your Ticker program playlist you did mention that if objects had Position Lock turned on they would not collide even if global Collisions Active selection and Ignore Collisions is not selected in the objects. I've tried creating a link between the two gears and various combination of options on the gears and link. Nothing I've tried gets the gears to behave like the gears in the video.
I do plan other tests. Is there anything I can do or print out that would help with this problem?
