A method and an apparatus provide for accurate positioning of a refiner head 10, having a tapered bore 14, on a tapered section 16 of a mating shaft 12. A circumferentially -mounted strain gauge 20 is provided on the internal surface of a recess 18 of the bore 14 and the amount of interference, in terms of hoop strain, between the shaft 12 and the refiner head 10 is measured to determine a precise interference between the refiner head 10 and the shaft 12. |
