Split frame device for performing operations on cylindrical items

A system, comprising:

• a split frame device having separable sections to enable mounting of the split frame device about a cylindrical item, the split frame device comprising:
• a plurality of non-rotating split frame steady assemblies supported by linear rails;
• a rotating tool carrier assembly movably mounted on the linear rails between non-rotating split frame steady assemblies of the plurality of non-rotating split frame steady assemblies, the rotating tool carrier assembly comprising a rotatable component, the rotating tool carrier assembly having separable sections to enable positioning about the cylindrical item such that the rotatable component may be rotated about the cylindrical item;
• and
• a power source mounted to impart rotational movement to the rotatable component.

A method, comprising:

• providing a split frame device with a rotating tool carrier assembly having a tool assembly configured to receive a tool;
• separating sections of the split frame device to enable positioning of the split frame device around a cylindrical item;
• positioning and closing the split frame device about the cylindrical item;
• operating the rotating tool carrier assembly to rotate the tool assembly about the cylindrical item;
• and
• subsequently releasing the split frame device from the cylindrical item.
