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 ch

ASSEMBLY ATTACHING LATHE BED 58" 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. Use the twelve 3/8-16 x 3/4” Hex Head bolts and lo

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. Th

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. After driving the center, hold the center Fig. 29 and the work together and fit both

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 tail- stock. Make the second pass beginning about 2” or 3” to Fig. 33 the left of the first cut. Advance again toward the tailstock, and merge with the previous cut. Toward the end of the live center, ro

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 striv- ing 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. As with the gouge, the skew can be adv

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 differ- ent manner from plain cylinder work. If the shoulder is long, use the ordinary skew position for the outer portion Fig. 43 Fig. 44 of the cu

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. Vee grooves can also be made with the toe of the skew, F

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. 57 Fig. 58 From the starting position, push the gouge into the revolving stock, a

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. Use a band saw on all work to roughly cut the tur
