Thanks Jerry for the info, The cherry log I turned two days ago was about 12 inches, what a log!!! One problem I have each time (all three bowls I've turned) is the tennon breaks off at the bottom using my G3 chuck. I'm making the tennon as big as the chuck will take but to no avial it breaks off and I have to turn another and clamp it back down. I forgpt to add one thing, it breaks off when I take the tail center of to turn with just the chuck. Not good to have a 12 inch green cherry bowl hitting the ground at your feet!
