Making some progress on my 5439 restore and fell backward a bit.
The headstock, crossfeed and under drive are restored. New found problem is my motor and motor pulley. It seems that in the past someone didn't install the key and the pulley was spinning on the motor shaft. The area where the pulley set screw was spinning on the shaft mushroomed making pulley removal without destroying the pulley bore impossible. I actually not only destroyed the bore but also broke the small pulley while attempting removal. I thought I might be able to save the motor so I pulled it apart for a bearing change. Not so good inside. the wires to the windings are shot, the insulation just cracked off. Now looking into VFD drive.
 
if the shaft of the motor is ok, you can solder new "tails" to the windings.
