I was given some pecan last year. I sawed the trunk into 5 bolts, the longest being about 4 feet so I could manage them by myself. Originally I sawed half into lumber and planned to use the other half for bowl blanks. Before you read on, just remember that NOW I think it’s great for bowls, but if you had asked me 8 months ago…
After green-turning five or six blanks, I decided to mill the rest of it into lumber. The wood was kind of wooly, especially at the bottom of the bowls. I tried spindle-turning some stock (to practice the skew chisel) and got a fair bit of tear-out in spots. A few days after roughing the first bowls I noticed they were warping like crazy. I figured I’d try soaking some fresh-turned rough-outs in Pentacryl stabilizer. That was interesting. I was going to wipe it on. When I poured some into the bowl it was so porous that it leaked all over my bench. I put it in a bucket, but it was still a mess.
The Pentacryl worked, but the wood is pretty plain looking, so unless it is spalted (I hear it spalts well), I didn't think it is worth the extra trouble.
Flash forward to this week. After about 8 months of seasoning, I chucked-up the first bowl. It was not warped all that bad after all. Apparently all the movement was in the first week (or so it seems). Now that it is dry, it turns fantastic with no tear-out at all. It sands easy and polishes very nicely with minimal effort. I finished the bowl with Hut PPP and then a final polish with plain beeswax (no need for a food-safe finish on a bowl that leaks). I now wish I had not sawed up all the bowl stock.
So, although your experience may prove to be different, I would say rough turn the bowls a little thick, don’t worry about the warping or tear-out, coat them with green-wood sealer so they don't crack, and let them season for 6-8 months. They should clean up really good.
