FUNCTIONAL DESCRIPTION FOREWORD The Delta 46-756 16” adjustable speed wood lathes is a big capacity machine, 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 tool and all loose items from the shipping container(s).
ASSEMBLY ATTACHING LATHE BED TO PEDESTALS 58" 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 (D) 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.
A D TAILSTOCK LIVE CENTER 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), use the knockout bar (C) Fig. 14 (supplied) through the hole (D) in the opposite end of the spindle. C B Fig.
STARTING AND STOPPING THE TOOL The power switch, located under the safety cover (B) Fig. 18 provides electrical power to the adjustable speed drive. Lift the safety cover (B) and move the switch up to the “ON” position. To turn the power off, push the safety cover (B) down. Fig. 18 shows the switch with safety cover down in the “OFF” position. Fig. 19 shows the lathe in the “ON” position (switch cover (A) up and switch (B) up).
C 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. A 6. The REVERSE (REV) button (D) Fig. 22 will reverse the spindle rotation. B D Fig. 22 C NOTE: When using the faceplate, tighten the faceplate locking screw (A) Fig. 23. NOTE: To remove the faceplate, loosen the set screw (A) Fig. 23 two full turns.
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.
B A Fig. 69 Fig. 68 6. Use an outboard tool rest (B) Fig. 68 for all outboard turnings. 7. Fig. 69 illustrates the correct method for outboard turnings. MAINTENANCE C A A B Fig. 71 Fig. 70 REPLACING DRIVE BELT 1. Use the supplied hex wrench (A) Fig. 70 to loosen the set screw in the handwheel (B) Fig. 70. Engage the spindle lock (C) and rotate the handwheel clockwise to remove. 2. Use an 11/16" wrench to remove the bolt (A) Fig. 71 from the motor yoke. C B A Fig. 73 Fig. 72 3.
B B A A Fig. 74 5. 6. Fig. 75 Use a Phillips screwdriver (A) Fig. 74 to remove the five cover screws (B) (three of which are shown). The other two screws are located under the power cords. With a 5/16” hex wrench (A) Fig 75, remove the hex screw (B) Fig. 75. NOTE: When re-assembling, pass the screw completely through the pivoting control bracket and into the headstock, allowing the headstock cover to pivot. A A B Fig. 77 Fig. 76 7.

KEEP MACHINE CLEAN LUBRICATION Periodically blow out all air passages with dry compressed air. All plastic parts should be cleaned with a soft damp cloth. NEVER use solvents to clean plastic parts. They could possibly dissolve or otherwise damage the material. Apply household floor paste wax to the machine table and extension table or other work surface weekly. Wear ANSI Z87.1 safety glasses while using compressed air.
