An orbital lathe for in situ resurfacing a fifth wheel kingpin, having a pin axis, where the orbital lathe includes a support column generally axially aligned with the pin axis of the kingpin, a cutting tool mounted to the support column for rotation about the pin axis and having a first positioning mechanism for moving the cutting tool at least radially relative to the pin axis, a second positioning mechanism for rotating the cutting tool about a centerline axis generally orthogonal to the pin axis, and a third positioning mechanism for moving the cutting tool parallel to the centerline axis, and a drive mechanism for rotating the cutting tool about the pin axis to cause the cutting tool to remove material from the kingpin. The position of the cutting tool in relation to the centerline axis determines a surface roughness of the kingpin. Another embodiment of the orbital lathe and a method are also disclosed.

In one aspect, a pipe machining system is provided and includes a positioning apparatus, a pipe machining apparatus, and an adjustment member coupled to the positioning apparatus and a pipe machining apparatus. The adjustment member is configured to move the pipe machining apparatus relative to the positioning apparatus. In one aspect, the pipe machining system also includes a position tracking apparatus configured to identify a position of the pipe machining apparatus relative to a pipe on which the system is mounted.

A tool for shaping an abradable liner of a turbofan engine is disclosed. The turbofan engine includes a shaft to support a fan rotatable about a rotation axis. The abradable liner is configured to surround the fan and has an axial length in the direction of the rotation axis. The tool includes a support configured to be mounted to the shaft and rotatable about the rotation axis. The shaping head is mounted to the support for rotation about the rotation axis and configured to shape the abradable liner by removing material from the abradable liner. A radial position of the shaping head is adjustable relative to the rotation axis. The shaping head may sized to extend substantially across the axial length of the abradable liner.

A method of fabricating a refrigerator cabinet or door includes forming a wrapper and an inner liner. The method further includes forming a vacuum insulated core comprising a permeable core material that is disposed inside an impermeable envelope. A sheet of prefabricated compressible foam material is positioned between the vacuum insulated core between the inner door liner and/or the door wrapper. The prefabricated compressible foam material may be cut from a sheet of foam having substantially uniform thickness prior to fabrication of the refrigerator door. The foam compresses to accommodate differences in spacing between the vacuum insulated core and the door wrapper and/or the door liner.

Lathe guard systems, remote lathe control systems, and portable lathe assembly kits including the same. A lathe guard system includes a ramp guard and/or a ring guard, each configured to be operatively coupled to a portable lathe to prevent the formation of a pinch point between a tripper pin tower and a tool slide assembly of a portable lathe. The ramp guard includes a ramped surface, and the ring guard at least partially overlaps the tool slide assembly to prevent the formation of a pinch point between the tripper pin tower and the tool slide assembly. Remote lathe control systems include an operator pendant configured to enable remote operation of a portable lathe and a control tether extending from the operator pendant. In some examples, a portable lathe assembly kit includes a portable lathe in combination with a lathe guard system and/or a remote lathe control system.
