After owning the lathe almost 20 years discovered the 8 inch 4 jaw chuck is only bolted on (no recess machined)
In my defense I seldom use it took it apart to clean it for the first time (I think getting old)
I set it up to machine it, the run out is about 0.0005 thou but I noticed the countersunk cap screws are set deep
there is only about 3/8 inch of meat left so if I machine 3/16 off its getting a little thin
I have come up with some options
Leave as is
Bolt and pin a spacer and machine it to fit the recess in the chuck
Hope I explained this okay
what are your thoughts
