My first question is where to install the DTI magnetic base in order to indicate radial and axial spindle bearing play. I've seen videos with the mag base on the headstock, and others with it on the lathe bed. Seems to me it should be mounted to the headstock in order to indicate bearing play, not the bed which may include play unrelated to the bearings?
If there is observable bearing play, what would be considered acceptable for this class of machine?
I've not disassembled the headstock to learn what bearings are installed, most likely stock. If I were to consider replacing the bearings with either angular contacts or tapered rollers, what sort of bearing play should I expect, assuming of course, I don't mess up the transplant?
Thank you.
