Figure 31 Make sure your clamping application will not fail! Figure 31. Use a minimum of three independent clamp- ing devices when using faceplate. Failure to provide adequate clamping will cause workpiece to eject during operation. Centers NOTICE Failure to keep a dead center tip well lubricat- ed will damage dead center and workpiece.
Page 30
Mounting Center in Spindle Note: When using the dead center in the spindle, use a lathe dog so that your part will rotate with the spindle and not spin on the dead center tip.
Offsetting Tailstock Aligning Tailstock To set up the tailstock to cut a shallow taper: Figure 35 Figure 35. Figure 36. Aligning Tailstock To align the tailstock: Note: Keep in mind that the point will have to be refinished whenever it is removed and returned to the chuck.

Running the coolant pump without ade- quate coolant in the coolant reservoir may permanently damage the coolant system on your lathe. This action is considered abuse and is not covered by the warranty. Maintenance To use the coolant system on your lathe: Figure Page 46...
Tool Post To load the tool post: Figure 48 Figure 48. Steps 1–3 Spindle Speed To calculate the correct spindle speed: Figure 49 Recommended Cutting Speeds Rough Cuts Note: These values are based on HSS cutting tools. For carbide cutting tools, double the aver- age speed.
Page 36
Cutting Speed (SFM) x 4 Spindle Speed = Diameter of Cut Example 1 Step 1: Step 2: Result: Example 2: Step 1: Step 2: Step 3: Result: Note: In most cases the calculated spindle speed will be between the available speeds. Use your best judgement when choosing either a higher or lower spindle speed.
Power Feed NOTICE Feed rate is based on spindle RPM. High feed rates combined with high spindle speeds result in a rapidly moving carriage or cross slide. Pay close attention to the feed rate you have chosen and keep your hand poised over the feed switch.
Figure 54. To set the feed rate: NOTICE NEVER move levers while the lathe is run- ning, and NEVER force any lever when shift- ing. If the lever will not engage, rotate the chuck by hand while keeping light pressure on the lever.
Thread Settings & Change Gears Always disconnect machine from power before changing gears. Accidentally starting machine during gear changes can cause serious personal injury. To set up for 1.75 pitch metric threads: Figure 57. Side View Figure 58. Figure 57 Figure 59.
Threading Controls Feed Direction Lever Neutral Figure 60. Feed Change Lever Figure 61. Half Nut Lever Figure 62. DO NOT engage the half nut when the spin- dle is operating over 200 RPM. Disregarding this warning may cause damage to the leadscrew and bearings.
