GROUNDING INSTRUCTIONS Qmunding Lug WARNING: Improper conr_dion d equipmed grounding conductor can ras.J in the dsk d electrical shod<. Eq_ment should be grounded while in use to protect operstor from eleddcal shock. • Adspter_ 3-Prong Check with a qualified elestdcian if grounding instructions are not understood or i in doubt as to whether the tool is Ground _A propedy grounded.
The power lines are inserted directly ontothe switch.The 0teen groundline must remain securely fastened to the freme to properlyprotect against electrical shock. • • • Remove the key to prevent unauthorizeduse. 240 VOLT OPERATION • • • • To use the lathe with a 240V, single-phase pov,,er supply, have s qualified electrician attach a 240 volt. 15A 3-prong plug Onto lathe line cord and install the proper connectors and receptacles to power supply.
SPINDLE TURNING • Observe the speed chart (see page 14). For example, a 2" square turning uP to 18" long should run at 1100 RPM for "roughing'. Rotate the wood by hand to make sum that the If you have never done any amount ot wood turning,we suggest that you practiceusing the variouswood turningtools. Start with a small spindle turning. Be sure to studythe follo_vingpages of this manuel.
Rgure 19 figure 16 - Bowl Turning CAUTION: Do not try to push this support when cutting.Do nottry to mountwork so large that the motor must strain to turn it. If youwish to experiment with thistechnique, do so with softwoods. Let the heavier, herder wood come later.
• The only sure method of holdingthe chisel steady is to mat the b_vel against the work (Figure 21A). When the toni mat is at the proper height, the chisel can be held with the bevel pressed against the work, and the tool restwill act as a fulcrum to support the chisel against the downward force of the revolvingwork. • Fig, 22A • ioe c If the rest is placed too low, so that the chisel is held with the bevel out from the work (Figure 21B), the cuttingedge will continueto dig deeper intothe work.
• USING THE SKEW • Any flat sudaca can be scraped with the flat nose chisel. Two skews, the '/z and 1" sizes, am all that are needed for general use. Other sizes are avallsble, This tool is nearly always used to ma_ fbished cuts, to cut vees and beads, and to square shoulders. Properly used, i produces the best finish that can he obtained with a chisel. It is not recommended for scraping because the edge tends to dul more qalddy.
Cutting to Depth Figure Many scraping operations and cUtting to depth with the parting tool can be easily accomplished with the one hand. The chisel is grasped firmly with the index finger on top to press it down against the rest. it is thrust straight into the work. Holding the tool in this manner leaves the other hand free to hold a p_tem or calipers, atc., to check work in progress.
• Roundness can be tested by laying the gouge on top of the work - it will not ride up and down when cylinder is perfectly found. Flrst Cuts Figure 38 Testing Roundness Figure • Use the gouge to remove any waste stock outside of shoulder. Smooth this section, up to within ',_" oOshoulder, in the usual manner. Finishing at the shoulder, unless it is more than 1" high, is best done with the q,_"sl_w.
• At the start of either cut, gouge is held with handle high and the two sides of blade held between the thumb end fore_ingar of tool rest hand, just behind the bevel. Position the fingers so that they are ready to roll the blade into cove.

• Next. prepare the turningstock by squanng it up to the size ot the largest square or round section in your plan. The stock can be cut to the exact length of the proposed turning.However, in mast cases, it is best to leave the stock a littlelong at one or both ends to allowfor trimming. • Mount the stock in the lathe and rough it otf to a maximum-size cylinder.
a Morse taper shank, it can be mounted directly in some tail stock rams. OthenNise, it can be mounted in a chuck fit- Alter completing the turning, remove the bankstick and finish off the original point of contact. Sand off aw slight burns remaining on workpiece, ted with the proper type shank. • CUTTING DOWELS Dowels of any size can be turned quicklywith the simplejig shown.It the stock is prepa,-odas a splitor quartered turning, half round and quarter roundswill be produced.
Rgure 56 FANCY FACEPLATE TURNINGS PREPARING Round Nose Chisel Sposr-Pdnt Chisel A PLUG CHUCK A plug chuck is an at_iliaq/wood chuck mounted onto a faosplste. The chuck can be any size diameter, but it should be about 1%" thick for stability. The wood chuck should be provided with a '_; or _,_" hole in the center for receiving a tenon Measuring Depth turned st the end of the workpieos.
RECHUCKING • Rechucidng is the general term used to descnbe any additional work mounting that is necessary to complete a turning projeot.The method of working ojlinders, and the use of a plug chuck as already described are typical examples. Another good eKample is the rechuddng of a bowl, Alter being shucked, the remaining face of the ring can be turned to the proper contour, thus cutting away the center portion.
• Next, the inside of the body is turned. A care/ul check must be made when turning the lip of the body podiorl so that the lid will be a tight press fit. • The lid is then pressed onto the body and the outer circumference and face of the lid, together with the outer drcumference of the body, are turned all at one tk_e.This insures accurate matching of the two pieces. • After the work is complete, the tight fit nt the lid can be relieved by sanding the lip of the body.
