The Cylinder The cylinder is the main element of a mechanical door lock. It houses a collection of spring-loaded pins that lock the door even when no key is inserted into the hole. When keys are inserted into the doorknob, the uneven edge pushes up on the pins within the cylinder, fitting them into their proper place. Once the pins are seated into the cylinder, they allow the bolt, also referred to as the latch to move forward and connect the door's interior. The bolt extends from the cylinder into a hole in your door frame, which is known as the box. The box is designed to fit the bolt tightly, so that it can't be easily opened. A clip spring ensures that the bolt is retracted when the door is closed. When you turn the handle to close the door, the spindle within the cylinder turns. The slanted end retracts into the frame of the door once the spindle has finished rotating. The bolt rests on the carved out part of the doorframe and keeps the door closed until you have to open it. A faceplate is a metallic plate that attaches to the inside of your door, either side of the deadbolt hole. Its job is to protect the mechanism of locking from damage caused by the knob's repeated removal and insertion. Are you installing a new lock?

Faceplates can accommodate various shapes, but in general they must be positioned, fixed and balanced, which are not easy tasks if compared to the ease of using a chuck. A typical faceplate is equipped with a number of mounting holes, in this instance three placed at 120Adeg spacing to receive the workpiece mounting screws 18 of FIG. 2. These screw holes are machined by an insert that can be interchanged or directly into the body of the faceplate. The faceplate has an incline in the middle, which serves as an index mark to locate the exact location of the blank workpiece. The stepping area has been designed to resist abrasion so that the fastener won't cause damage to the chisel used to cut it. The surface of the faceplate body has different properties from the surrounding area. Machining into this area alerts the turner to possible imminent contact with fasteners and allows them time to react. Screws used to hold a faceplate in place should be of a size that can fit inside the screw hole, leaving only a tiny amount of play. When the screw is fastened onto the glue block there should be no space behind it. This could permit the block during rotation to shift.
