Live center installed. Figure 24. Faceplate and dead center installed. NOTICE Failure to keep dead center point well lubricated will gall the dead center and workpiece. -26- M1049 Benchtop Lathe (Mfg. Since 8/09) SHOP FOX, Using the Steady Rest The steady rest serves as a support for long shafts. The steady rest can be placed anywhere along the length of the ways. To use the steady rest, do these steps: 1. Carefully place the steady rest on the lathe bedways. 2. Loosen the finger lock nuts so the finger position can be adjusted (see Figure 25). 3. Insert the workpiece, and support it with the chuck and the tailstock. 4. Position the steady rest along the workpiece where desired. Tighten the steady rest lock nut (see Figure 25) to secure the steady rest in place. 5. Turn the adjustment knobs so the fingers are snug against the workpiece and then tighten the finger lock nuts. Figure 25. Steady rest adjustments. Note: You must lubricate the finger tips with oil during operation to avoid tip galling. After prolonged use, the fingers will show wear, so you will have to replace or file the tips for a new contact surface. Using the Follow Rest The follow rest in Figure 26 is mounted on the saddle and follows the movement of the tool. The rest requires only two fingers, as the cutting tool acts as the third. The follow rest is used on long, slender parts to prevent flexing of the workpiece during cutting. Note: You must lubricate the finger tips with oil during operation to avoid tip galling. After prolonged use, the fingers will show wear, so you will have to replace or file the tips for a new contact surface. Figure 26. Follow rest attachment. -27- OPERATIONS OPERATIONS SHOP FOX' M1049 Benchtop Lathe (Mfg. Since 8/09) Setting Compound Slide The compound slide is used to cut tapers on parts or to set the proper infeed angle when threading. It may also be used to cut specific lengths longitudinally, when set parallel to the spindle axis. To set the angular position, do these steps: 1. Loosen the hex nuts, one on each side of the compound slide (see Figure 27). 2. Rotate the compound slide to the desired angular position using the scale. 3. Tighten the two hex nuts. Be sure to not overtighten, as you may strip threads or crack or distort the base casting. Figure 27. Compound slide, scale, and handwheel. Using the Tool Posts The four-way tool post (Figure 28) is mounted on top of the compound slide, and allows a maximum of four tools to be loaded simultaneously. The four-way tool post allows for quick indexing to new tools. This is accomplished by rotating the top handle counterclockwise and then rotating the tool post to the desired position. Rotate the top handle clockwise to lock the tool into position. The universal single tool post holder can hold tool arbors and odd shaped cutting tools (Figure 29). Figure 28. Four-way tool post. Figure 29. Universal tool post. -28- M1049 Benchtop Lathe (Mfg. Since 8/09) SHOP FOX, Using Manual Feed You can manually move the cutting tool around the workpiece with the three handwheels shown in Figure 30. Longitudinal Handwheel The longitudinal handwheel moves the carriage left or right along the bed. This control is helpful when setting up the machine for turning or when manual movement is desired during turning operations. Cross Feed Handwheel The cross slide handwheel moves the top slide toward and away from the work. Turning the dial clockwise moves the slide toward the workpiece. Compound Slide Handwheel The compound slide handwheel controls the position of the cutting tool relative to the workpiece. The graduated dial is adjustable using the same method as the dial on the cross slide. Angle adjustment is held by two hex nuts on the base of the compound slide. Figure 30. Carriage controls. -29- OPERATIONS OPERATIONS SHOP FOX' M1049 Benchtop Lathe (Mfg. Since 8/09) Setting RPM To determine and set the needed cutting RPM, do these steps: 1. Use the table in Figure 31 to determine the cutting speed required for the workpiece material. 2. Determine the average final diameter of the workpiece in inches, for the cut to be made. ▲warning Failure to follow RPM and feed rate guidelines may threaten operator safety from ejected parts or broken tools. 3. Now use the following formula to determine the closest RPM for the cutting operation: (Cutting Speed x 4) = RPM Diameter of Cut 4. With the calculated RPM, refer to the RPM Chart on Page 31 and select the pulley ratio that gives you the closest RPM to what you need. 5. DISCONNECT THE LATHE FROM POWER! 6. Release the belt tension lever (Figure 32). 7. Make sure the spindle is completely stopped and then open the belt access door (Figure 33). 8. Move the belt to the appropriate pulley combination that is closest to your calculated RPM.
