I have a 10 by 36 Atlas lathe with a MT#3 in the spindle. This lathe was well used. It looks like a collet may have spun in the spindle. The collet has about .005 run out. The bore is not as smooth as it should, but I don't feel any burs that would account for the run out. The outer diameter of the spindle is about 1/2 thousandth out so not likely any other issue. What is the best way to true it up? I need some guidance on this as it needs to be done correctly. Thanks
PS. I checked my 9 by 18 Logan and it was about 1/2 thousandth both on the collet and outer diameter of spindle.
