I have been working with wood for about 50 years, for most of that time I made tables and cabinets for use in my home. Since I retired, and I don't need anything more in my home, I have started making small wooden boxes, primarily as gifts for family and friends.
About 3 years ago, my son refurbished my Dad's 60 year old wood lathe, and returned it to me as a birthday gift. Since then, I have been learning to turn, first, pens and now bowls. Pruning a large Siberian elm in my backyard provided a large amount of practice wood, which has resulted in production of a number of bowls, again for family and friends.
I now listen for sound of chainsaw in the neighborhood, and track its location as a potential source of more wood for my lathe. Almost all of my bowls are made from locally harvested wood, either from pruning or storm damage. I turn all my bowls from green wood. If I finish a bowl before it dries, then the final shape deviates from round as the wood dries and warps. If i rough turn a bowl blank, let it dry, and then finish turning it, the bowl ends up round.
