I was playing with some red oak I had recently acquired and turned a greenwood bowl down nice and thin. I wanted to see how it would look on drying so I chucked it into the oven and set it on the warm cycle for several hours. That one worked pretty good with no splitting so I tried another shaped a bit different. Of course this time there were cracks and rifts showing that I had to fix with sawdust and glue. Then I got the bright idea to put the bowl in a bag I would normally use for rough turned work to dry in. The next one was thicker but even thickness and I left it on the lowest bake temp I could get my oven to display which was 170F. After leaving it overnight and the bag quit steaming up my glasses every time I checked it the bowl came out looking quite nice. Apparently the bag keeps the bowl in a steambath as the water escapes so the wood remains pliable all over as the moisture content drops, in spite of the heat and rapid drying. I'm going to try this on a rough turned poplar bowl and see if it looks any worse off than a room temp dried bowl. I'm sure this is no cure-all for drying problems and will have problems all its own but at least its another option for getting work onto the lathe in less time.
