Beleive it or not i can not find anywhere on the internet how to do the following.  
I have a pool ball that is 2 1/4" in diameter. (This is an actual ball, not a picture or drawing), with this ball i would like to mark exactly a north and south pole, then scribe a line around the ball connecting the two points. Then would like to do this for the east and west poles. So when i am finished i have a ball with a cross if looking at from any angle. I thought i was really close when using a compass, in which i think this would be the correct route to take.

Please any suggestions would be great.
