A method of making ceramic bodies includes systematically orienting the bodies during firing relative to a temperature gradient in a kiln. The method includes the steps of displaying a template eye image to assist the user in visualizing selected options for a customized contact lens, and displaying a plurality of contact lens selection options to the user. In one embodiment, the port is selected using a port selection table weighted according to the ports speeds of the ports of the link aggregation group. The tradeoff is a slight increase in computation time for message decryption and message authentication. The modular drive system and handle set of the modular power tool of this invention reduces the need for derivative circular saw designs by introducing common components.
