Abstract
A hollow winding bobbin base (18) is constructed of a material having a relatively low thermal coefficient of expansion (e.g., quartz) and has a pair of flanges (32) slidably located on the ends. A metal tube (24) is received within the base (18) and has annular springs (40) on its ends urging the flanges (32) toward each other. An elastomer baselayer (30) is fitted onto the outer surface of the base (18).
