OPERATIONS, CONT.

Speed Selector

The variable speed selector allows the adjust- ment of the spindle R.P.M. Before turning the lathe on, make sure the speed selector knob is set at the lowest R.P.M. (turn counterclockwise).

Figure 7.

Once the lathe is turned on, slowly increase the R.P.M. of the lathe by turning the speed selector knob clockwise. Make sure that your finger is poised on the STOP button, just in case there’s a problem. The lathe should run smoothly, with little or no vibration or rubbing noises. Strange or unnatural noises should be investigated and cor- rected before operating the machine further.

If you cannot easily locate the source of an unusual noise or vibration, contact our service department for help.

Remember to choose the correct speed for your particular turning project. As a gener- al rule, the larger the workpiece diameter, the slower the speed should. Always start at the slowest speed.

Figure 7.

Tool Rest

Adjust the tool rest as close to the workpiece as possible without actually coming into contact with the workpiece. Test by hand-turning the work- piece before starting the lathe. Ensure that the lathe chisel is fully supported by the tool rest. Support the lathe chisel on the tool rest with one hand, while the other hand controls the chisel.

Figure 8.

Make sure the live center in the tailstock lines up with the spur center in the head- stock before turning anything between the centers. Failure to observe this step could result in the workpiece being thrown from the lathe. Serious personal injury could occur if care is not taken.
