I am trying to make a spindle nut for an old Jet Drill/Mill. The shaft thread OD is 1.153". The nut ID is 1.119". 1.25mm left-hand thread. I made an aluminum prototype. The threads were good but the fit was much too loose. My original bore was 1.115". I know it has to be less but how much less than the nut @ 1.119"?
