The accompanying photograph is almost a story without words, showing a 16-24 foot extension boring and turning mill of the Niles Tool Works, Hamiltin, O., in operation on a 130,000 pound fly-wheel 23 foot 6 inches in diameter, the housing being moved back on the bed as shown, illustrating the extension feature admirably. It also shows the method employed to hold this large wheel on the comparatively small table, the radial arms, the jacks and the inclined struts or braces to take the thrust of the tool.
The rim of this wheel is 18 X 18 inches, and it was turned on the face and both sides in forty-eight hours, which speaks well for the stiffness of the tool as well as the efficiency of the operator. |
