If I waited ten years before using a peice of wood, i'd have bought it in high school & still would never have built a single cue as of yet!!!!
There are no major differences between kiln dried wood & air dried wood. Once dry it's dry. The one exception is vacuum drying, which is in itsself an entire science. Some vacuum kilns are microwave assist, so the wood is heated to incredible temps & the wood is dry in days. Not all are microwave assist, and do not heat the wood. Besides the microwave assist kilns, I believe any drying method known is fine so long as it does a thorough job. Dehumidifier kilns with no heat are kinda like hastened air drying. That said, I prefer air dried wood. It is most natural & there is no chance of chemical or structural alteration. A candle kiln, conventional, is next best thing. It's also the most preferred amoung the high end wood working & lumber world. The general rule is that if you have enough time, dry the wood conventionally. If you are in a hurry or need high output, dry it in a vacuum but be sure to do it exactly right. Vacuum drying is a science, complicated & complex. Otherwise, wood drying is pretty elementary stuff. People do it in their homes, or build small sheds, or even use old refrigerators with a dehumidifier. But in the end, once the wood is dry & cured, it's done.
More importantaly than the drying method is the turning method. That's where you either meet success or failure. It's something you learn as you go, and every builder has his/her own methods. Nothing is written in stone, so you can't break any rules. Try this, try that, use what works best.
