Figure 6B. Spur center set into wood stock.

4.Once the spur center is firmly attached to the workpiece, insert the spur center (with the attached workpiece) into the headstock spin- dle. Be certain the hex nut is threaded onto the spindle before tapping the spur center in.

5.While supporting the workpiece, slide the tail- stock close to the end of the workpiece and lock it into place.

6.Line up the live center with the workpiece center. Turn the handwheel to press the point of the live center into the workpiece.

7.Lock the tailstock in place.

Do not press too firmly or the bearings will bind and overheat. Likewise, do not adjust too loosely or the workpiece will spin off the lathe. Use good judgement. Serious personal injury could result if care is not taken.

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). See

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. Always start at the slowest speed.
