I have an idea for a project that is like a segmented bowl. What I need to figure out are the angles that are needed. Example: If I want to have a eight picture sided frame my angle is 20 Degrees. If I want to have an 8 sided bowl you need the taper and side angles that will be determined by the length of the side. I have figured out a jig for this and could keep changing the angle of the table saw blade until I get one that fits but it would be nice to have a formula to calculate the side angles based on the number of wedges and the length of the wedge. That would save a lot of wood and I would be able to change the size of the bowl.
