Glue up 3/4 x 1/8th in strips 10-12 inches long. Shorter may work until you have a 10x5-6 inch block. set your miter gage on your saw to 15 degrees or what ever you like. That will cut the block on an angle. Decide on how many panels you want and divide that number into 360. Set your saw blade angle at that answer. Cut off the end waste, flip it end for end, front to back after each pass. Not left to right. glue up the wedges.
