ABSTRACT:
A wedging member, such as a ball, is frictionally engaged with inclined supporting ends of a pair of contact elements at a calibration temperature. The wedging member retains the positioning of the supporting ends as the temperature is changed from the calibration temperature to a hardening temperature for a hardenable material, such as an inorganic-base chemical-setting cement, for rigidly securing the supporting ends.
