HEADSTOCK.
The lathe Headstock used, site (4q48.com) at one time, to be known as the "Mounted Headstock" or "Fixed Head", and the rotating shaft inside it the "Mandrel". At present the mandrel is often known as the "Spindle", but this can cause confusion with the tailstock, where the sliding bar is thought variously because the "ram", "barrel" - and "spindle".
The headstock is normally mounted rigidly to the bed (exceptions exist in some production, CNC, automated and "Swiss-auto" varieties) and holds all of the mechanisms, together with varied sorts and combos of pulleys or gears, so that the spindle may be made to show at totally different speeds.

The headstock bearings may be worn. On Logan lathes, these bearings are cartridge ball bearings. If you feel any roughness whenever you turn the spindle by hand, you need new bearings. If the spindle moves in and out, it could be that the bearings are good, however the spindle is insufficiently tightened or incorrectly assembled. You can get new cartridge bearings from Logan or from a bearing dealer.
