POWER CONNECTIONS A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should be protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 3-prong grounding type plugs and matching receptacle which will accept the machine’s plug. Before connecting the machine to the power line, make sure the switch (s) is in the “OFF” position and be sure that the electric current is of the same

UNPACKING AND CLEANING Carefully unpack the machine and all loose items from the shipping container(s). Remove the rust-preventative oil from unpainted surfaces using a soft cloth moistened with mineral spirits, paint thinner or denatured alcohol. Do not use highly volatile solvents such as gasoline, naphtha, acetone or lacquer thinner for cleaning your machine. After cleaning, cover the unpainted surfaces with a good quality household floor paste wax. ASSEMBLY For your own safety, do not

ATTACHING THE BED EXTENSION Disconnect the machine from the power source! The total bed length of the lathe (center to center) can be increased to 37" by purchasing and installing an accessory bed extension. To attach the bed extension to the lathe: 1. Align the two holes in the end of the lathe bed (A) Fig. 30 with the two holes (B) in the end of bed extension. Fasten the extension to the lathe bed with two M10 x 40 x 1-1/2" hex head screws, lockwashers, and flat washers (C) using the suppli

HOW TO TURN SPINDLES Spindle turning is turning a workpiece attached to the lathe centers, and is used for chair and table legs, lamp stems, etc. You can use either a scraping or cutting technique for spindles. The cutting technique, by virtue of faster wood removal and a cleaner surface, is the preferred method. CENTERING THE WORKPIECE Wood stock for any spindle turning should be approximately square, and the ends should be square with the sides. Two common methods of determining the center

TOOL REST POSITION Mount the tool rest in place about 1/8" away from the work and 1/8" above the workpiece centerline (Fig. A7.) This position may be varied to suit the workpiece and the operator. Place a guide mark on the tool rest shank as an aid to quick and accurate resetting. Fig. A7 Fig. A8 Fig. A9 ROUGHING A CYLINDER Use the large gouge in the first turning operation to smooth the sharp corners of the workpiece. Run the lathe at low speed and hold the gouge in the manner shown in Fi

The alternate position is a palm-down grip (Fig. A12). In this position, the heel of the hand or the little finger serves as a guide. The palm-down position is solid and positive – excellent for roughing or heavy cutting. Most beginners start with the palm- down grip, switching later to the palm-up position for better manipulation of the chisel. SMOOTHING A CYLINDER To smooth a cylinder, use a large skew chisel. This requires practice, but experience with this tool is very important. Place

CUTTING A SHOULDER Use the parting tool first to reduce the wood to within 1/16” of the required shoulder diameter (Fig. A18). Clean the waste stock out with the gouge (Fig. A19), then use the skew (Fig. A20) for the actual cutting of the shoulder (a duplication of squaring an end). Use the skew to make the horizontal cut, but in a different manner from plain cylinder work. If the shoulder is long, use the ordinary skew position for the outer portion of the cut. At the angle between the

VEE GROOVES Cutting the vee groove demands much the same technique as the bead, except the skew is hinged straight into the workpiece without rotation (Fig. A27). Only one-half of the vee is made at a time, and one, two, or more cuts may be needed on each side to obtain the desired shape. As in all cutting with the skew, the bevel next to the cut must be used as a fulcrum. Be careful not to allow full edge of the chisel to catch and cause a run. You can also make Vee grooves with the toe

Place the gouge on the edge of the tool rest so that the grind of the chisel forms an approximate right angle with the workpiece (Fig. A33). Allow the chisel to contact the workpiece at the center of the cutting edge. Hold the tool so that the centerline of the gouge is pointing directly toward the center of the revolving stock. This starting position is important to prevent the gouge from running along the surface of the workpiece. Fig. A33 From the starting position, push the gouge into

FACEPLATE TURNING Mount most turnings that cannot be worked between centers on a faceplate. Some jobs require special chucks. All cutting in faceplate work is done by scraping. Any attempt to use a cutting technique on the edge grain of large workpiece will result in a hogging, gouging cut which may jerk the chisel out of your hands. Use a band saw on all workpiece to roughly cut the turning area to eliminate heavy roughing cuts in turning. MOUNTING THE WORKPIECE TO THE FACEPLATE Fig. A39 sho
