I have a nine inch cedar log which I want use to cover a four inch jack post supporting a beam in our basement. I had the log split in half, and now I need to hollow it out. A friend says he uses multiple passes with a circular saw, adjusting the depth as he proceeds. The sounds to me like a recipe for a lot of toothpicks if I were to do it. Anybody have a an idea of a semi-foolproof way of doing those? Anyone used a router? Other methods? I would appreciate any ideas or help.
Thanks, Jim
