I have wanted to wood turn a bowl from a finger jointed box. I picked out a piece of walnut and a piece of cherry. I milled each piece to the same dimension. I then made segments for a ring from these two pieces. I milled the end of each segment on the CNC router, to form a finger joint between each segment in the ring. I attached a bottom to the bowl by cutting a circle into the end of the ring to receive a round segmented bottom. I turned all of this on the lathe to the form finished bowl.
