FUNCTIONAL DESCRIPTION FOREWORD These Delta 16” adjustable speed wood lathes are large capacity machines, designed for industry, commercial shops, and schools, or wherever a demand exists for continued accuracy and long life through safe, heavy-duty operation. UNPACKING AND CLEANING Carefully unpack the machine and all loose items from the shipping container(s).
ASSEMBLY ATTACHING LATHE BED TO PEDESTALS 1. Remove the tailstock, headstock, and tool rest from the lathe bed. NOTE: See “ADJUSTING HEADSTOCK AND TAILSTOCK” and “TOOL REST” for removal/installation instructions. 2. Set the pedestals exactly 58” apart (Fig. 5). 3. Because of the weight, use an assistant to place the lathe bed on top of the pedestals. Align the holes in the lathe bed with the holes in the tops of the pedestals (A) Fig. 6C. 4.
ATTACHING LEG INSERTS B The lathe is supplied with four leg inserts, one of which is shown (A) Fig. 10. To attach the leg inserts to the pedestals, place one side in the hole provided and gently tap the other side, top, and bottom with a rubber mallet (B) Fig. 10. A Fig. 10 Attach the Headstock (A) Fig. 11, Tool Rest (E), and Tailstock (F) to the lathe bed (G). Notice the tool and centers storage areas located at (H), and brackets on the pedestals to accept a 2 x 12” shelf (not supplied) (J) Fig. 11.
TAILSTOCK LIVE CENTER A D The tailstock live center (A) Fig. 14, supplied with your lathe, is equipped with a No. 2 Morse Taper shank. NOTE: Before inserting the live center, clean both the shank and the inside of the tailstock to remove any grease or debris. To remove the live center (A) from the tailstock spindle (B), insert the knockout bar (C) Fig. 14 (supplied) through the hole (D) in the opposite end of the spindle and push the center out.
STARTING AND STOPPING THE LATHE The power switch, located under the red switch cover (B) Fig. 18 controls the electrical power to the machine. Lift the switch cover (B) and move the switch up to the “ON” position. To turn the power off, push the switch cover (B) down. B Fig. 18 shows the switch with switch cover down in the “OFF” position. Fig. 19 shows the lathe in the “ON” position (switch cover(A) up and power switch (B) up).
4. 5. To stop the spindle without turning the power off, press the stop button (C) Fig. 22 on the control panel. To restart, press the FWD button (B). The spindle will gradually return to the speed at which it was stopped. B 6. The REVERSE (REV) button (D) Fig. 22 will reverse the spindle rotation. 7. To return back to forward direction, press FWD button (E) Fig. 22. When using the faceplate, tighten the faceplate locking screw (A) Fig. 23 to avoid personal injury or damage to the machine.
OPERATION The following directions will give the inexperienced operator a beginning point for common lathe operations. Practice on scrap material before attempting serious work. LATHE TOOLS Standard wood turning tools come in several different configurations (Fig. 26). The majority of turnings will require the gouge tool (A) Fig. 26. This round nosed hollow chisel is used for roughing cuts, cove cuts and other operations. The skew chisel (B) is a double-ground flat chisel, with an angled end.
After marking each end, mark the true center with a punch awl or dividers (Fig. 29). If the stock is hardwood, the centers should be drilled to a depth of about 1/8”. The spur or live center is then placed against one end of the work and seated by striking with a mallet (Fig. 30). In hardwood, make a starting seat for the spur center by sawing on the diagonal lines, and drilling a small hole at the intersection.
ROUGHING A CYLINDER The large gouge is used in the first turning operation by smoothing the sharp corners of the work. Run the lathe at low speed and hold the gouge in the manner shown in Fig. 33 The cut starts about 2 inches from the tailstock end and continues from this point to the end of the tailstock. Make the second pass beginning about 2” or 3” to the left of the first cut. Advance again toward the tailstock, and merge with the previous cut.
SMOOTHING A CYLINDER To smooth a cylinder, use a large skew chisel. This requires practice, but experience with this tool is very important. Place the cutting point near the center of chisel and high on the work (Fig. 38). Sometimes, in striving for a certain position in relation to the work, the beginner will often overlook this all-important point. Raising the handle will increase the depth of cut while lowering the handle, of course, does the opposite.
CUTTING A SHOULDER Use the parting tool first to reduce the wood to within 1/16” of the required shoulder and diameter (Fig. 43). Clean the waste stock out with the gouge (Fig. 44), then use the skew for the actual cutting of the shoulder (Figs. 45A and 45B), which is a duplication of squaring an end. The skew then makes 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.
VEE GROOVES Cutting the vee groove demands much the same technique as the bead, except the skew is hinged straight into the work without rotation (Fig. 51). 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.
The gouge is placed on edge on the tool rest so that the grind of the chisel forms an approximate right angle with the work (Figs. 57). The chisel contacts the work 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 work. Fig.
FACEPLATE TURNING Mount turnings that cannot be worked between centers on a faceplate. The greater part of this type of turning is done with the faceplate mounting, although there are a number of jobs which 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 work will result in a hogging, gouging cut which may jerk the chisel out of the hands of the operator.
OUTBOARD TURNING For workpieces that require additional space for turning, or for the turning of bowls, etc., outboard turning is the answer. To make outboard turnings: 1. Remove the tool rest base and the tailstock from the lathe bed. 2. On the headstock, raise the handle (A) Fig. 65 to loosen the tension of the headstock on the lathe bed. 3. Lift the motor slightly and slide the headstock to the end of the lathe bed. (See also Fig. 69) 4. Lower the handle (A) Fig. 65 to lock the headstock in place. 5.
MAINTENANCE C A A B Fig. 71 Fig. 70 REPLACING THE DRIVE BELT 1. Use the supplied hex wrench (A) Fig. 70 to loosen the set screw in the handwheel (B) Fig. 70.
