Faceplate
This section outlines basic operation safety related to using the faceplate included with your lathe. Use knowledge of
safety and common sense when applying the steps on how to use this faceplate.
The faceplate is cast-iron and has multiple slots for T-bolts that hold clamping hardware. If you suspect that any of
the chuck or jaw combinations may not hold a workpiece safely, remove the chuck and install the faceplate as
outlined for special clamping options.
However, just as with the 4-Jaw chuck, not all workpieces can be safely held. Holding a workpiece off center or
holding an irregular shaped workpiece will cause the entire assembly to rotate out of balance. If spun at any speed
higher than low, the workpiece can eject hitting the lathe operator or bystanders causing a severe or fatal injury.
Figure 21 shows an example of a workpiece being improperly held with the 4-jaw chuck. One jaw of the chuck
interfered with the workpiece edge, and removing the jaw creates an extreme workpiece ejection hazard. The
workpiece holding solution shown in
figure 21 is to use the faceplate with a minimum of three clamps that are spaced
as equally apart as possible for full support.
Figure 21 Figure 22
To use the faceplate:
1. Disconnect lathe from power!
2. Insert a dead center into the tailstock, slide the tailstock up to the faceplate, and lock the tailstock into position.
3. Place the workpiece against the faceplate and turn the tailstock quill so the point of the dead center touches and
applies enough pressure to hold the workpiece in place.
4. Lock the quill when sufficient pressure is applied to hold the workpiece. Additional support may be needed,
depending on the workpiece.
5. Clamp the workpiece at a minimum of three locations that are as close to being evenly spaced apart as possible as
shown in Figure 23.
WARNING! Use a minimum of three independent clamping
devices when using faceplate. Failure to provide adequate
clamping may cause workpiece to eject during operation.
6. Double check for safety and rotation clearance.
7. Slide the tailstock away from the workpiece and install the
required tailstock tooling for drilling or boring, or position
the tool bit for facing.
