Warren and Brown self-centering chuck
Before the war many essential tools and equipment were imported from overseas. As they became unavailable, Australian companies were requested to undertake this manufacturing. One of the very special items developed at W & B was the self-centring lathe chucks in a range from 3″ to 12″. The standard of lathe chucks met the highest world regulations. Unfortunately, when hostilities ceased the specialised equipment was put in cold storage, due to the economics of volume.
