Inspect the doorknob shaft and locate the set-screw, slot or small hole. If a screw is visible, insert a screwdriver and turn counterclockwise to remove the screw - free the knob by pulling. Faceplates The faceplate is used for holding work that, because of its shape and dimensions, cannot be swung between centers or in a chuck. The T-slots and other openings on its surface provide convenient anchors for bolts and clamps used in securing the work to it.
A lathe faceplate is a basic workholding accessory for a wood or metal turning lathe. It is a circular metal (usually cast iron) plate which fixes to the end of the lathe spindle. The workpiece is then clamped to the faceplate, typically using t-nuts in slots in the faceplate, or less commonly threaded holes in the faceplate itself.
The faceplate may be attached to the lathe in several ways: the two most common are a thread and a precision cone arrangement, and threaded studs and a circular recess fitting a flange on the end of the spindle. Increasingly common is the camlock arrangement, in which shaped studs and cams replace threaded studs for rapid exchanging of the faceplate with other accessories, such as three or four jaw chucks.
The faceplate was the ancestor of lathe chucks, an arrangement of three or more adjustable 'dogs' bolted to the faceplate providing a primitive chuck arrangement. The smaller plate in the upper photo is specifically a 'dog face' with slots intended to hold a bent tail dog while the work itself was supported on centers. The larger plate to the right simply provides a variety of ways by which work can be bolted or clamped to the plate. The slotted plate on the lower photo accepts wedged holders which can be used to fasten the work to the plate. The plates were expendable, so it was not unusual as shown in both photos for a machinist to drill additional holes in the plates for attaching work that could not otherwise be attached. While the dog plates were usually fairly small regardless of the lathe size, the classic face plate is usually matched to the maximum diameter that the lathe will swing.

It may seem that a faceplate is a primitive accessory superseded by precision chucks, but its inherent flexibility (almost any shape can be attached to a faceplate with care and the right fixings) and the possibility of achieving great accuracy by careful setup make it essential for a well equipped lathe.
For certain specialist jobs, temporary or special faceplates can be made, perhaps in wood or light alloy, that can be machined or adapted for difficult workholding jobs. One example might be attaching thin sheet metal to a wooden faceplate using wood screws, allowing the trepanning of holes, with the tool cutting into the sacrificial faceplate material.

T Slot Plate 28
If you receive a new faceplate, use the following procedure to replace it. The faceplate comes on the robot and available separately.
T Slot Plate
Press the bin release button on the back of the robot to remove the bin. The bin release tab has a bin icon on it.
- Position Roomba on its side, with the bumper facing down and on a soft, flat surface.
- Press into the faceplate using the allotted pressure points to release the faceplate from the robot.
- To install the faceplate, line up the tabs on the faceplate with the allotted slots on the robot.
- Press down on the pressure points to snap it into place.
- Slide the bin into the bin slot, securing it into place.
