With the temporary machining adapters Loctited in place, set up the spindle between centres. Take light cuts, use a very sharp tool and you will have no difficulty. The ball races want to be a snug sliding fit on the spindle shaft. The end of the spindle is turned down to 18mm dia. and threaded with a 1mm pitch (or any convenient thread) for a length of 40mm and should end just inside the rear ball race. Photograph 3 {M.E. 4324, 25 April 2008) shows the 50 tooth by 2.5mm pitch timing pulley and two threaded locking rings. The pulley has also been threaded with a lmm x 18mm thread.
