Tutorial for spinning gears animation

[-=Drifter=-]

simsmj: My sincere apologies if I inferred that your tutorial did not work. Your tutorial is EXCELLENT! The problem was ME! I went back and did every single step extremely carefully. You explained the procedure very precisely and accurately. The first time I just tried to rush through it and in the end failed.
I have learned a lot from you. Thank you.
This is just my first result - no textures added.
I am really curious HOW in the world you figured out how to do all of this!!!!!
