Drive Plate

Refer to the prior Chuck Installation and Chuck Removal sections for instructions on installing or removing the drive plate.

The drive plate included with your lathe is used for straight turning between centers. The Figure below shows a straight lathe dog (not included) attached to the workpiece. The end of the dog rests against a drive plate pin.

Failure to properly secure a workpiece to the faceplate could cause the workpiece to be thrown from the lathe with deadly force. To reduce this risk, use a minimum of THREE independent clamping devices to hold the workpiece onto the faceplate.

To mount a non-concentric workpiece to the faceplate:

protect the bedway with a piece of plywood.

With help from another person or a holding device to support the workpiece, position it onto the faceplate and clamp it in place with a minimum of three independent clamping devices (see figure below for an example).

Be sure to take into account the rotational and cutting forces that will be applied to the workpiece when clamping it to the faceplate. if necessary, use counter-weights to balance the assembly and use a dial indicator to make sure that the workpiece is properly positioned for your operation.

refer to the prior chuck installation and chuck Removal sections for instructions on installing or removing the faceplate.

the faceplate included with your lathe can be used for a wide range of operations, including machining non-concentric workpieces, straight turning between centers, off-center turning, and boring.

the tools needed for mounting a workpiece will vary depending on the type of setup you have.

Machining non-concentric workpieces at high speeds could cause the workpiece to be thrown from the lathe with deadly force. To reduce this risk, do not exceed 395 RPM, and use counter-weights to balance the faceplate or workpiece.
