Paper Abstract

The present evaluation of the design philosophy of the Apache Point Observatory's 3.5-m altazimuth-fork mount telescope gives attention to such detail-design problems as the mirror-cover system, the upper azimuth bearing and support system, and the spherical bearing mountings. A four-roller constraint for the upper azimuth bearing and support system proved to be a superior design solution than the originally intended two-roller constraint. A cone-shaped structure on the lower fork defines the azimuth axis; the center of the drive disk defines the top end of the axis while the spherical roller thrust bearing defines the lower end.
