Abstract: A levelling machine includes a pair of spaced apart rail assemblies, a gantry assembly and a face mill assembly. The spaced apart rail assemblies define an x axis. The gantry assembly is moveably attached to the pair of spaced apart rail assemblies whereby the gantry assembly defines a y axis. The gantry assembly is moveable in the x axis along the pair of spaced apart rail assemblies. The face mill assembly is moveably attached to the gantry assembly and is moveable in the y axis along the gantry assembly. The face mill assembly has a plurality of saw blades, the saw blades being generally in an x-y plane defined by the x axis and y axis. The saw blades have a plurality of teeth that extend downwardly generally in a z axis. The face mill assembly is moveable in the z axis.

Abstract: The present subject matter relates to systems, assemblies, and methods for connecting structural members together. A connector assembly includes an elongated track having a web, opposed edge portions that extend from a first surface of the web and that form a pair of slide channels, and one or more protrusions protruding from a second surface of the web opposing the first surface, the one or more protrusions being configured to connect to the first building member. A connecting member is adapted to connect to the second building member and includes a base that retains the connecting member to the channels but is movable within the channels along the track. In this configuration, when the connector assembly is connected between the first and second building members, the connecting member is movable in the track in response to relative movement between the first and second building members.
