This is another 1913 gun lathe from Armstrong Whitworth’s Openshaw works.100″ swing, 80 ft between centres. 60 HP main motor.The ‘tool post’ nearest the tailstock is for supporting a 12″ diameter boring bar.For quick movement of the tailstock barrel the large handwheel/flywheel is used. For ‘forcing the centre into the work’ the small handwheel is engaged. The enlarged diameter at the front of the tailstock casting is actually a shrunk-on steel ring, to reduce the possibility of the tailstock casting bursting under the load
