   It would be enough slow it with a Variac and spot drill the indexed   
   locations with a #3 center drill in the collet for further work on the mill.   
   I bored an index disk to fit on the spindle behind the chuck or collet   
   thread protector.   
      
   The South Bend lathe milling attachment can apply forces in directions the   
   carriage wasn't meant for. That became obvious when I made a milling vise   
   attachment in night school for my smaller lathe. It has no carriage hold   
   downs in front and the rear ones are out of sight. The fix would be bolts   
   with two heads.
