Turning Bowls

I was taught how to turn a bowl.  The wood was green.  I wanted to know if I enjoyed doing it, so I went to a two day class.  I did manage to turn two bowls, one is cracked around the edges, due to the wood drying faster than I could turn the wood.  We will see if turn another bowl, I may.  To get the equipment and tools I need to spend another $300, and am not sure I will turn enough to warrant that money.  I do have a lathe and did clean up these bowls on that lathe.  I had trouble in the class because the distance of the tools on the bowl did not match my focal length.  The teacher at one point, when I asked him again to get my tools started at the right angle, asked if I needed a time out... I told him no, I just need to get started with the tool and then  I can feel my way through the rest... he took the time out and left the room.  The other student came over and we got the tool at the right angle and all went well!  Oh well, I have never been a good student.
