Apparatus for translating objects along a path is constructed in a manner which automatically conforms surfaces of a guideway with adjacent surfaces of a rail that extends along the guideway and thereby realizes very precise travel. A housing containing the guideway initially has a channel that is broader than the guideway. Plates are loosely disposed in the channel and strips of resilient material extend from the plates to the channel walls. The rail is emplaced between the plates and a cover plate is secured to the housing over the rail. This wedges the plates apart and compresses the resilient material while causing the top of the rail to be strictly parallel with the cover plate and while causing the plates to be strictly parallel with the rail side surfaces. Hardenable liquid adhesive is injected into the channel to unitize the plates with the housing.
