I will explain and demonstrate the process I use to create a bowl or vase, which is square on top and tapers to round at the bottom. Starting with a square or rectangular blank that has been prepared on a bandsaw to taper the sides, the remaining exterior corners will be turned leaving the four tapered sides previously cut on the band saw. Then the interior of the bowl or vase will be turned into the square top. The basics of bevel-supported cuts along with two of the most important fundamentals of turning – sharp tools and good tool control will be emphasized.
