A guide (82) includes a first section (84a, 84b) connected to base (18) and a second section (94) connected to table (60). First section (84a, 84b) cooperates with second section (94) to laterally maintain base (18) on table (60) while allowing thermal expansion of base (18) in the direction of a longitudinal axis (22).

[ We claim:] [1.] A method for setting up calibrators having passageways that define profiles, said calibrators being used in a thermoplastic extrusion system, said method comprising the steps of:aligning the calibrators on one side of a base such that selected points on the profiles of the respective calibrators define a longitudinal axis, where the side of the base that is oppositely disposed from said one side has one member of a guide secured thereto;positioning the base on a work table that has a second member of the guide secured thereto, said second member of said guide cooperating with said one member such that the one member of said guide that is secured to the base engages the cooperating member of said guide that is secured to the work table; andsecuring said base to said work tablesuch that one member of said guide is slidable with respect to the other member of said guide in response to temperature variations of said base and in response to temperature variations of said work table.
