This column base is used in conjunction with the Horizontal Milling Conversion and allows the spindle center to go below the top of the table, meaning you can machine the edge of material overhanging the table. The cutoff piece from the column is machined flat and re-tapped to be used as a spacer block to return the mill to its normal height.
It includes a shortened column top, 2″ column bottom and two 3″ x 1/4-20 screws.
Always wear safety glasses when operating machine tools.
