WARNING: Machine tools present a safety hazard. Improper operation can result in severe injury. These topics are for non-laboratory study only and are not to be used in conjunction with the operation of any tool or machine described herein. Never use a machine tool without the supervision of a qualified instructor.
The carriage is a combination of five main parts; the saddle, the cross-slide, the apron, the compound rest and the tool rest (left top). The purpose of this combination is to hold a cutting tool securely while at the same time moving it (feeding) to whatever position is necessary to machine the work piece.

The Apron is the front vertical face of the carriage. It is a covering plate or a casting that houses gears, clutches and levers. The apron has an autofeed knob, a shift-feed knob (left middle), and a threading nut engagement handle (left bottom).

The autofeed handle will engage or disengage all feed motions. The shift-feed handle will change the feed from the carriage to the cross slide or visa versa. Somewhere on the headstock there will be a feed-reversing handle. This handle changes the direction of rotation of the feed rod, thus reversing the feed direction of the cross slide and the carriage. The thread engagement handle engages the threading nut.
