I have a Southbend heavy 10 lathe. The adaptor in the spindle that holds the dead center is missing.
Does any one know the taper of the spindle. It has a D1-4 spindle. The closest I can measure it appears to be .056/in..The large end measures about 1.652.
A #5 morse seems to fit but is too large, a#4 is too small. A #5 should be .052626/in. and a #4 .051938/in.
