Abstract
The Canada-France-Hawaii-Telescope has placed in operation a servo controlled roller-screw support system for its primary mirror. This paper will address the goals of CFHT in upgrading from a fixed `bendix' style mirror supporting defining pads. The main design criteria was to have a system that would define the mirror like the original pads, but have adjustability to remove coma dependent on telescope position.
