Once a log is milled, the wood needs to be dried. Airdrying can work, but that takes a very long time, sometimes several years. My kiln can take that extremely long process, and shorten it into several weeks instead. If you're looking to invest time and effort into building a high quality piece of furniture, you want to do everything you can to make sure the wood will be as stable as possible, and that there are no bugs living in the wood; my kiln will do that.
Of course I dry all my own wood, but I also enjoy drying for other local woodworkers. Kiln space is tight, so let me know what you need dried and I'll schedule you in.
