Use of wood screw
The screw chuck is helpful when turning larger workpieces.
1.Turn OFF and unplug your lathe.
2.Mount the screw chuck in the chuck with an internal grip. The bottom lip of the screw chuck
should be under the jaws to help hold it in place.
3.The base of the workpiece should be flat and square to its sides. Using an 8.3mm (21/64") drill
bit , drill a pilot hole straight down into the center of the workpiece,
approximately 31mm (1-7/32") deep.
4.Screw the workpiece onto the screw chuck. The base of the workpiece should be flush against
the top of the jaws
