ABSTRACT:
An adjustable mandrel for securing a portable lathe adjacent the end of a pipe to be prepared for welding includes a lathe support plate that is adjustable about a single miter axis relative to the body of the mandrel which is arranged to engage the I.D. of a pipe. The portable lathe is connectable to the support plate by means of a mandrel engaging fixture that enables the cutting plane of the lathe to be located adjacent the pipe end. The miter axis of the mandrel is always located so that it lies in a direction that is parallel to the cutting plane of the portable lathe. The miter angle can be set within a range of positions so that the pipe end can be cut at a precise miter angle in preparation for welding to another pipe section.
