leadscrews are used within the cross- slide and compound to move those parts by precise amounts.
Morse Taper (MT): A taper of spe- cific dimensions used to mate match- ing male and female parts together tightly. The spindle has a #3 Morse Taper
Saddle: An “H” shaped casting that rides along the ways. A main compo- nents of the carriage.
Spindle: Main rotating shaft on which the chuck is mounted. It pass- es through the headstock.
Spindle
Swing: A dimension representing the largest diameter workpiece that a lathe can rotate. The 9x20 lathe has a 9” swing, meaning that the maximum size workpiece that can rotate without hitting the bed is 9” in diameter.
Tailstock: Assembly that slides along the ways and can be locked in place. Used to hold long workpieces in place or to mount a drill chuck.
Tailstock Handwheel: Moves the tailstock in and out. Has a tapered internal bore to accept a #2 Morse Taper shank.
Tool Post: A device mounted on the compound that holds the cutting tool.
Turning: A lathe operation that re- moves metal from the outside diam- eter of the workpiece.
Ways: Surface along the top of the bed on which the saddle rides. The ways are aligned with the centerline of the lathe.
Installing a Chuck
1.Place a piece of wood on the bed of the Lathe to prevent possible damage to the Ways.
