Vaughn pretty much covered the gamet. If you turn a bowl green to finish it is going to warp especially fruit woods. I found for me anyway that apple moves the most. I soak my fruit wood in DNA for up to 5 days, wrap like on Dave's site and in about 3 to 4 weeks it is ready to return to the lathe to be finished. I have also started to use anchorseal after seeing Mike Mahoney at a demo and talking with him. He fully paints each bowl with anchorseal and says they are ready for returning to the lathe in 90 to 120 days. I just did one that had that treatment and sat for 181 days. It turned just fine. Since I am getting ready to retire I won't be in such a hurry to finish bowls so thought I would give the anchorseal method a go. So far with walnut, elm, cherry, ash and apple no cracks. Mike said in all his years of turning he has lost very, very few bowls. Some like Vaughn said are going to crack no matter what method you use. So you will have some artistic firewood. I don't mess with bowls that are cracked bad because life is to short to mess with bad wood.
