Compare against the list below. Do not discard the carton or any packaging until the lathe is completely assembled.
  • Page 7 ASSEMBLY MOUNTING THE LATHE ON THE BENCHTOP Measure and mark three hole centers as shown in Figure A. Drill clearance holes through the bench top and position the lathe in place. Attach it securely with bolts (minimum of one inch) and washers (not included) from the underside of the bench top into the tapped holes in the bottom of the lathe’s frame.
  • Page 8 ASSEMBLY INSTALLING THE DRIVE SPUR AND REVOLVING CENTER (FIG. F & G) Note: It is not necessary to remove the face plate in order to install the spur center. 1. Make sure the surfaces of both the spur center and the spindle are clean.

  • Page 9: Adjustments

    ADJUSTMENTS ON/OFF SWITCH The ON/OFF switch (Fig. I - 1) controls the power to the unit. To start the lathe, move the switch into the ON position (flipped up). NOTE: This lathe features a gradual start up, meaning that the chuck will not start spinning until couple of mo- ments after the switch is turned ON, and will start spinning at a lower speed before gradually ramping up to its full RPM.
  • Page 10 ADJUSTMENTS TAILSTOCK 1. Move the tailstock (Fig. J - 5) by loosening the lock lever (Fig. J - 1) and pushing the tailstock to the desired position on the bed. Lock it back in place by tightening the lock lever again. 2.

  • Page 11: Operation

    OPERATION TURNING TOOLS If possible, select only quality high-speed steel turning tools. High-speed steel tools hold an edge and last longer than ordinary carbon steel. As one becomes proficient in turning, a variety of specialty tools for specific applica- tions can be acquired. The following tools provide the basics for most woodturning projects. 2.
  • Page 12 OPERATION SPINDLE TURNING Spindle turning takes place between the centers of the lathe. It requires a spur center in the headstock and a live center in the tailstock. A cup center rather than a cone center in the tailstock will often reduce the risk of splitting the stock.
  • Page 13 OPERATION CUTTING TECHNIQUES Begin with a large roughing gouge. Place the tool on the tool rest with the heel of the tool on the surface to be cut. Slowly and gently raise the tool handle until the cutting edge comes into contact with the workpiece. Beginning about 2 inches from the tailstock end of the workpiece, roll the flute of the tool (the hollowed-out portion) in the direction of the cut.
  • Page 14 OPERATION Fig. U Fig. T Fig. W Fig. V MOUNTING ON THE FACE PLATE Use of the face plate is the most common for holding a block of wood for turning bowls and plates. This is an alternative option for workpieces with diameters that are greater than the 12-inch throat of the lathe. To mount the stock to the face plate, select a stock that is at least .2 inches (5 mm) larger than each dimension of the finished workpiece.
  • Page 15 OPERATION TO SHAPE THE OUTSIDE OF THE BOWL (FIG. X) Odd shaped burls, crotches and other irregular shaped blanks require special preparation before mounting in a chuck or onto a face plate. Remove the bark, if there is any from what appears to be the center of the top of the workpiece.

  • Page 16: Maintenance

    MAINTENANCE Keep your machine clean. At the end of each day, clean the machine. Wood contains moisture, meaning that sawdust and wood chips can cause rust if not removed. Regular oil attracts dust and dirt. Teflon lubricant tends to dry and has less of a tendency to accumulate dirt and saw dust. Periodically check that all nuts and bolts are tight. The drive belt should last for many years depending on usage, but it needs to be inspected regularly for cracks, cuts and general wear.
