We just learned about the Lathe - Headstock.
Another part of the metalworking lathe is the Tailstock.
Just like the headstock holds one end, the tailstock holds the other end of the metal being worked on.
When the piece of metal is put onto the lathe, first the metal is placed up against the headstock, and then the tailstock is moved closer and closer until it is holding the metal tight between both spindles.
The tailstock is moved by spinning a small wheel called the "handwheel" or "feed screw".
After the metal piece is in the right place and held tightly by both the headstock and tailstock, a locking lever is pulled down that works like a clamp to keep the tailstock from moving.
