Various improvements have been made to render each machine quickly and readily handled by workmen from one position front of table; attention also is given to making table true with spindle, each machine being carefully inspected before and after completion; spindles, studs, shafts, of steel; cones carefully balanced; centre hole in spindle, Morse Standard Taper. All drills except lever have hand and automatic feed; spindles and sliding heads counterbalanced; the different feeds are carefully adjusted to suit the drilling of steel or cast iron without straining or breaking; on end of spindle we make large head having an oil reservoir by which oil is kept constantly between end of sleeve and washer, where greatest pressure occurs when drilling. Especial attention is asked to our method of balancing Radial Drill Spindles, being always constant and out of range of belts.
