Round column milling machine modifications

I made a modication to afford a more repeatable location of the milling head on a round column Warco economy mill. I also fitted a stop to the cross slide (Y axis) as the machine does not have one. I also made a shorter chucking arrangement so that changing to drills of different lengths is both quicker and less problematic than using the supplied 2MT taper shank chuck that came with the mill.
