Right this moment the mandrel is normally known as the "Spindle", but this could cause confusion with the tailstock, where the sliding bar is thought variously as the "ram", "barrel" - and "spindle".<br>The headstock is generally mounted rigidly to the bed (exceptions exist in some production, CNC, automatic and "Swiss-auto" varieties) and holds all of the mechanisms, including varied varieties and combos of pulleys or gears, in order that the spindle will be made to turn at completely different speeds.<br><br>The headstock bearings could also be worn. On Logan lathes, these bearings are cartridge ball bearings. If you're feeling any roughness while you turn the spindle by hand, you need new bearings. If the spindle moves in and out, it may very well be that the bearings are good, however the spindle is insufficiently tightened or incorrectly assembled. You will get new cartridge bearings from Logan or from a bearing dealer.<br>
