While the front bearing might have been entirely conventional, the construction of the rear, together with its built-in end-thrust arrangement, was not. The bearing's lower half was madewith a full thread on its outer end that carried a narrow screwed ring (with traditional twin knurls), a screw-on end cap and a tubular distance piece. All parts were made (expensively) in bronze and the end float of the spindle adjusted by screwing on the end cap until the distance piece came up against the end of the spindle with the setting locked by the knurled ring.
