Gear Exercise

Process:

  Firstly, I create a pipe polygon with many subdivisions as shown above.

 
Then I switch to face mode. I select alternate faces along the ages and scale them accordingly.

Then I scale them outwards to form the teeth of the gear.

This is my final outcome.

Reflection:

This exercise is relatively simple as the flash video was clear and easy to follow. I've learnt to operate the extrude functions on multiple faces at the same time, which will prove useful when creating objects such as the gear above.
