Description:

Abstract:

A surfacing machine mountable within a valve body includes a tubular turning bar supported by chucks engaging the valve body and having independently adjustable legs and a bearing arrangement which permits rotational and axial movement of the turning bar relative to the chucks. Hoses and control rods are routed through the tubular turning bar to a removable tool head which may be accessed when deep within the valve body. The arrangement facilitates both visual and physical access to the work site such that an operator may exchange tool heads to switch surfacing operations without changing the mounting alignment of the surfacing machine within the valve body.
