    I just bought a Clausing 8540 horizontal milling machine and I need to see if anyone has prints for
    or can draw up some good sketches for the draw bar, overhead support, and brace to the overhead support to the knee. Or even some real good pictures with a ruler
    would be of some good help

    Most steel suppliers can also supply cast iron of various sizes and alloys.

    http://www.indiastudychannel.com/re...ypes-of-Iron-and-its-material-properties.aspx
    Grey cast iron and its properties:


    Grey cast iron can also be produced from pig iron.
    • Grey Cast Iron is an alloy of Carbon & silicon with iron.

    • Carbon percentage of Grey Cast Iron: 2.5 to 3.8 %

    • Grey cast iron is having Self damping, good antifriction properties and also having lowest melting point. This is the reason why grey cast iron is mostly used in machining bed to reduce and absorb the vibration due to self damping properties.

    • Applications of Grey Cast Iron : Machine tool structure, manhole covers , piston rings, rolling mill. Water pipes.
