16-Speed Gearhead Lathe

To mount a non-concentric workpiece to the faceplate:

1.DISCONNECT LATHE FROM POWER!

2.Protect the bedway with a piece of plywood.

3.With the 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 45 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.

Positioning Tailstock

1.Pull the tailstock lock lever backward (away from the spindle) to unlock the tailstock from the bedway.

2.Slide the tailstock to the desired position.

3.Push the tailstock lock lever forward (toward the spindle) to lock the tailstock against the bedway.

Tailstock

The tailstock (see Figure 46) is typically used to support long workpieces by means of a live or dead center (refer to Centers on Page 43). It can also be used to hold a drill or chuck to bore holes in the center of a part. Custom arbors and tapers can also be cut on your lathe by using the offset tailstock adjustment.

Using Quill

1.Release the quill lock lever.

2.Turn the tailstock handwheel clockwise to move the quill toward the spindle or counterclockwise to move it away from it.

3.Push the quill lock forward to lock the quill in place.
