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 characteristics as indicated on the machine. All line connections should make good contact. Running on low voltage will damage the machine.

DANGER
Do not expose the machine to rain or operate the machine in damp locations.

MOTOR SPECIFICATIONS
Delta Models 46-756 and 46-755X are wired for 230 volt, 50/60 HZ alternating current and provide a no-load spindle speed of 0-3000 RPM. Before connecting your machine to the power source, place the switch in the “OFF” position.
NOTE: The specifications on the motor will read “230 volt-3 phase”. This is correct and is accomplished with a high frequency inverter.
IMPORTANT: The motor cannot be run without the inverter.
NOTE: The power supply to the inverter is 230 volt, single phase.

CAUTION
Do not change the input voltage. To do so will cause severe damage to the inverter.

GROUNDING INSTRUCTIONS

DANGER
This machine must be grounded while in use to protect the operator from electric shock.
Grounded, cord-connected machines intended for use on a supply circuit having a nominal rating between 150 – 250 volts, inclusive: If the machine is intended for use on a circuit that has an outlet that looks like the one illustrated in Fig. C, the machine will have a grounding plug that looks like the plug illustrated in Fig. C. Make sure that the machine is connected to an outlet having the same configuration as the plug. No adapter is available or should be used with this machine. If the machine must be re-connected for use on a different type of electric circuit, the re-connection should be made by qualified service personnel. After re-connection, the machine should comply with the National Electric Code and all local codes and ordinances.

EXTENSION CORDS
WARNING
Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire extension cord which has a 3-prong grounding type plug and matching receptacle which will accept the machine’s plug. When using an extension cord, be sure to use one heavy enough to carry the current of the machine. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Fig. D-1 shows the correct gauge to use depending on the cord length. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

DANGER

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. Use the twelve 3/8-16 x 3/4” Hex Head bolts and lock-washers to attach the lathe bed to the pedestals.

NOTE: Level the machine by loosening the jam nut (A) Fig. 6C and turning the adjusting nut (B). When leveling is complete, tighten the jam nut (A).
To increase the height of the machine, place a 4″ wide hard-wood board (A) Fig. 6A between the pedestal (A) Fig. 6B and the pedestal base (B) Fig. 6B.

NOTE: Place the 4″ board under the pedestal, mark where the holes are located, and drill the holes to allow longer carriage bolts (not supplied) to come through.
Fold the metal flap (C) Fig. 6D down and out of the way to fill the pedestal with sand or concrete to provide more ballast.

NOTE: If sand is used, pour a small amount of concrete or similar material in the pedestal to prevent sand leakage through the seams.
In addition to showing the location of the bolts (A and B), Fig. 7 also shows that additional ballast can be added in the lathe bed (C). Steel bars or other heavy material can be inserted into the lathe bed to provide more weight.
NOTE: Use a good quality furniture wax on the lathe bed (C) Fig. 7 to allow for smoother movement of the headstock, tool rest, and tailstock, and to prevent rust.

ATTACHING END CAPS
Use the supplied hex wrench (B) Fig. 9 to attach the end caps (A) Fig. 8 to both ends of the lathe with button head screws (A) Fig. 9.

Insert these through the end cap, then the lathe bed. Secure with a flange nut (B) Fig. 8 .

NOTE: The flange nut can easily be dropped while attaching the endcap. A metal flap (C) Fig. 6D will catch any fallen flange nuts. However, if you folded the flap down to insert more ballast, use a piece of cardboard or other material to cover the hole during assembly.

ATTACHING LEG INSERTS
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.

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.
If additional stability is desired, insert a 4 x 4 (A) Fig. 11 into the pedestal base (B) Fig. 11.

NOTE: You may have to cut a groove in the 4×4”s to allow the lumber to pass underneath the head of the carriage bolt.
Fasten the 4 x 4’s to the floor.

HEADSTOCK SPUR CENTER
The spur center (A) Fig.12 is equipped with a No. 2 Morse Taper shank. Insert this shank into the headstock spindle (B).

NOTE: Before inserting the spur center (A), clean both the shank of the spur center and the inside of the head-stock spindle to remove any grease or debris. To remove the tapered shank spur center (A) Fig. 13 from the head- stock spindle (B) Fig. 13, insert the knockout bar (C) Fig. 13 (supplied) through the hole (D) in the opposite end of the spindle and push it out.

IMPORTANT: Never drive the workpiece into the spur center when it is mounted on the headstock.
See the instructions on setting the spur center into the workpiece in the “OPERATION“ section of this manual under “CENTERING THE WORK.”

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), insert the knockout bar (C) Fig. 14 (supplied) through the hole (D) in the opposite end of the spindle and push the center out. Or, fully retract the spindle with the handwheel to eject the center.

ADJUSTING CLAMPS ON THE HEADSTOCK AND TAILSTOCK
The headstock and tailstock can be moved along the lathe bed. A downward push on the handle (A) Fig. 15 (tailstock shown) locks the mechanism, while an upward movement of the handle releases the securing action. The clamps are pre-set at the factory. However, should either need adjusting, use an 11/16” wrench (B) Fig. 15 to slightly loosen or tighten the two nuts (C) Fig. 15 shown here on the tailstock.

NOTE: Tighten or loosen both nuts equally.

• Clamp the headstock and tailstock firmly while operating the lathe.

TOOL REST
The tool rest (A) and tool rest base (B) are shown in Fig. 16. To position the tool rest on the lathe bed, lift the clamp handle (C), move the tool rest base and lock it in place by pushing down on the handle (C). To adjust the tool rest (A) for the correct height, loosen the locking lever (D), move the tool rest (A) up or down and tighten the locking lever (D). NOTE: The locking lever (D) Fig. 16 can be positioned on the left or right side of the tool rest base (B). To reposition the tool rest locking lever (D), unscrew the lever counterclockwise. A threaded hole is provided in the left side of tool rest base (B) to accept the locking lever (D) if desired.

NOTE: Clamp the tool rest firmly while operating the lathe.

ADJUSTING THE CLAMP ON THE TOOL REST
To adjust the tool rest clamping action, use a 11/16” wrench to loosen or tighten the single nut (A) Fig. 17.

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” posi-tion. To turn the power off, push the switch cover (B) down.
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).

WARNING
When the machine is turned off using the stop button (A) Fig 18A, the spindle will decelerate under power. When the machine is turned off using the switch cover (A) Fig 19, the spindle will free spin until it stops. Always use switch cover to PREVENT entanglement in rotating parts.
DELTA DOES NOT RECOMMEND the use of any optional brake systems on the lathe. Further, DO NOT CHANGE OR ADJUST the controller settings that have been pre- set at the factory.

LOCKING THE SWITCH IN THE “OFF” POSITION
IMPORTANT: When the machine is not in use, the switch should be locked in the “OFF” position to prevent unauthor-ized use, using a padlock (A) Fig. 20 with a 3/16” diameter shackle inserted through the holes in the switch plate (C) Fig. 19.

ACTIVATING THE SPINDLE
Even though power may be going to the adjustable speed drive, the spindle will not turn until you activate it.

1. Before activating the spindle, tighten and clear all clamps, bolts, etc. Turn the workpiece by hand to see that it clears the tool rest and to make sure that the spindle lock is in the UNLOCKED position (A) Fig. 21.

2. Prior to activating the spindle, set the speed control knob (A) Fig. 22 to the “zero” position.
   CAUTION
   Input voltage must be 200 to 240 single phase.
   Other voltages will severely damage the inverter.

3. After turning the power switch on, push the “run” button (B) Fig. 22. Then slowly turn the knob (A) clockwise to the desired speed. NOTE: The numbers in the display multiplied by 10 will indi-cate the spindle speed.

4. To stop the spindle without turning the power off, press the stop button (C) Fig. 22 on the control panel.

5. To restart, press the FWD button (B). The spindle will gradually return to the speed at which it was stopped.

6. The REVERSE (REV) button (D) Fig. 22 will reverse the spindle rotation.

7. To return back to forward direction, press FWD but-ton (E) Fig. 22.

WARNING
When using the faceplate, tighten the faceplate locking screw (A) Fig. 23 to avoid personal injury or damage to the machine.
NOTE: To remove the faceplate, loosen the set screw (A) Fig. 23 two full turns. Engage the spindle lock (C) and use the supplied wrench (B)

Fig. 24 to loosen the face-plate. Remove the face plate from the spindle.

NOTE: Use the chart (B) Fig. 25A on the front of the door for safe operation.

IMPORTANT: For emergencies, use ONLY the red switch cover (A) Fig. 19 to stop the machine. Also, when leaving the machine, lower the switch cover to cut the power to the whole machine. Pressing the stop button on the control panel only cuts power to the adjustable speed drive. This control is still energized as long as the power switch is on.
NOTE: To lock the spindle or to utilize the indexing fea-ture, pull the spindle lock pin (A) Fig. 25 out and rotate the pin clockwise. Engage it in the pulley holes (B) Fig. 25, some of which are shown. The spindle pulley has 24 holes accurately spaced around the rim of the pulley. This feature makes it possible to make evenly spaced divisions on turnings which could be fluted, grooved, or to mark places to be drilled.

• Delta does not suggest the use of any optional brake systems on the lathe. Further, DO NOT CHANGE OR ADJUST the controller settings that have been pre-set at the factory.

CHANGING ACCELERATION/DECELERATION

WARNING
When using the faceplate, tighten the faceplate locking screw (A) Fig. 23 to avoid personal injury or damage to the machine.
To change the acceleration/deceleration rate, loosen the screw (A) Fig. 25A and open the door. This machine has two different acceleration/deceleration speeds. For larger workpieces, move the switch (A) Fig. 25 B up to the “SLOW” position. For smaller work-pieces, move the switch down to the “FAST” position. Refer to the chart on the front of the variable speed drive.

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. This tool is used for smoothing cylinders, for cutting shoulders, beads, vee- grooves, etc. The parting tool (C) is a double-ground chisel, used for cutting-off, or for making straight incisions or sizing cuts to any required diameter. The round nose scraper (D) is used for mostly hollowing work, while the square-end scraper is mainly used for the outside of bowls.

HOW TO TURN SPINDLES
Working with any material that is attached to the lathe centers is called a spindle turning. This is the principal type of wood turning (chair and table legs, lamp stems, etc.) The turning of spindles can be done with either a scraping or cutting technique. The cutting technique, by virtue of faster wood removal and a cleaner surface, is the preferred method.

CENTERING THE WORK
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 are shown in Figs. 27 and 28. In Fig. 27, a distance a little more or a little less than one-half the width of the stock is set off from each of the four sides. The small square set off in the center can then be used in marking the true center. The diagonal method, Fig. 28, consists of drawing lines from corner to corner, with the intersec-tion marking the center of the work.

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 and the work together and fit both immediately to head-stock spindle. If you are not using a ball bearing center, the end of work at tailstock center should be oiled. Place the lubricant on the wood either before or after it is put on the lathe. Many turners use beeswax, tallow, or a wax-and-oil mixture as a lubricant. A ball bearing center is ideal because it eliminates lubricating. If the work is to be removed from the lathe before completion, an index mark should be made as a guide for re- centering (Fig. 31).

A permanent indexer can be made by grinding off one corner of one of the spurs.

MOUNTING THE WORK
Mount the work by moving the tailstock to a position about 1” or 1-1/2” from the end of the workpiece, and locking it in this position. Advance the tailstock center by turning the feed handle until the center cup makes contact with the work. Do not support the work on the center pin alone. Always have the rim of the center cup imbedded at least 1/8” into the work. Continue to advance the center while slowly rotating the work by hand. After it becomes difficult to turn the work, slack off on the feed about one-quarter turn and lock the tail-stock spindle.

TOOL REST POSITION
Mount the tool rest in place about 1/8” away from the work and 1/8” above the work centerline (Fig. 32.)

This position may be varied to suit the work and the operator. Place a guide mark on the tool rest shank as an aid to quick and accurate resetting.

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. Toward the end of the live center, roll the gouge in the opposite direc-tion (Fig. 34) to carry the final cut off the live center end of the work.

The roughing cut should not be carried out with one continuous movement, because this would tear long slivers from the corners of the work. Neither should the cut be started directly at the end of the stock for the same reason. The cut can be safely carried from the center of the stock toward and off either end once the first roughing cuts have been made. The position of the gouge involves two or three important angles. (1) The tool may be advanced along the work either from right to left or from left to right. Left to right (from headstock to tailstock) is preferred since this action throws chips clear of the operator. (2) The gouge is rolled over slightly in the same direction it is advancing. (3) The tool is held well up on the work, with the bevel or grind tangent to the revolving surface (Fig. 35).

This position will give a clean shearing cut. When pushed straight into the work (Fig. 35), the gouge has a scraping action, (normally a poor practice in spindle turning). The roughing cut is continued until the work approaches 1/8” of the required diameter. Once a cylindrical form has been obtained, the turning speed can be moved to the second or third speed setting. NOTE: Continue to move the tool rest inward toward the work piece to keep the safe distance between the two.

POSITION OF HANDS

While turning, the hand that holds the tool handle should be in a natural position. This hand provides the leverage for the tool by either moving in toward the chisel or moving out. The position of the tool rest hand is more a matter of individual preference, rather than a “set” or “proper” position. However, a palm-up grip (Fig. 36) is generally considered best. In this position, the first finger acts as a guide, sliding along the tool rest as the cut is made. The alternate position is a palm-down grip (Fig. 37).

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 the cutting point near the center of chis-el and high on the work (Fig. 38).

Sometimes, in striving for a certain position in relation to the work, the begin-ner 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 advanced in either direction. The center of the skew toward the heel does the actual cutting. The back portion of the grind or bevel supports the tool, while the handle-hand controls the depth of cut by rocking the chisel on this pivot point. Because of this, keep the skew bevel perfectly flat.

USING THE PARTING TOOL
The parting tool is perhaps the easiest turning chisel to handle. Simply push this scraping tool into the work Fig. 39.

A somewhat better cutting action is obtained if the handle is held low. This tool is, in many cases, held with one hand while the other hand holds the calipers in the cutting groove. When parting tool cuts are deep, a clearance cut should be made alongside the first cut (Fig. 40) to prevent burning the tool point.

SQUARING AN END
The parting tool can be used to quickly square an end. Since the parting tool is a rough cutter, the cut can then be smoothed by the use the skew. However, the whole operation can be done with the skew. In using the skew, make your first cut a nicking cut with the toe of the skew (Fig. 41).

A deep cut here could burn the chisel, so a clearance cut is made by inclining the skew away from the first cut and pushing the tool into the work. This procedure of side cut and clearance cut is contin-ued as often as needed. NOTE: While the skew can be pushed into the wood in any direction, the cutting edge itself must be inclined a little away from this plane .If the full cutting edge of skew bears against the cut surface, the tool will have a tendency to run. See Fig. 42 for the proper way to make the cut. Push the chisel straight into the work, and incline the cutting edge away from the cut surface. Use only the extreme end of the toe for this cut. This important principle in skew handling will be used repeatedly in making shoulders, beads and vee cuts.

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 shoul-der is long, use the ordinary skew position for the outer portion of the cut. At the angle between the horizontal and vertical cuts, the heel of the chisel moves into a position tangent between the skew and the cylinder (Fig. 46).

In this position, raise the handle of the chisel slightly to allow it to cut while the tool moves along the rest. Use a very light cut to produce smooth work. The heel of the skew can be used for making the entire cut, if desired, but the cut, whether in this position or any other position, should not be picked up directly at the end of the stock. Horizontal cuts started directly from the end of the work will have a tendency to bite into the wood, often ruining the entire piece. Always run off the end and not into it. Where a very short shoulder makes this impossible, use the skew in a flat scraping position. If the cutting technique is used, engage only with the heel of skew in a very light cut.

CUTTING SMALL BEADS
Beads can be scraped or cut. Using the spear chisel is the easiest method of scraping, and works to best advantage on beads separated by parting tool cuts (Fig. 46).

Scraping is slower than cutting and is not as clean, but it has the advantage of protecting the work from long gashes. Cutting beads quickly and accurately with the small skew is one of the most difficult lathe operations. Various working methods can be used . The first cut is a vertical incision at the point where the two curved surfaces will eventually come together. Make this cut with either heel or toe of skew. Fig. 47 shows the use of the toe. Place the skew at right angles to the work .

The chisel is flat on its side at the start, and is evenly rotated through the successive stages of the cut (Figs. 48, 49 and 50).

At the same time, the chisel is pulled slightly backward to maintain the cutting point. The entire cut is made with the heel of chisel. The opposite side of the bead is cut in the same manner, one cut serving to produce the full shape in each instance. This action produces beads that are beautifully smooth and polished, and the technique is well worth mastering.

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, in the same manner as squaring an end.

LONG CUTS
Long cuts are usually either convex or straight-tapered surfaces. With a convex surface, the method used in making the finishing cut is shown in Figs. 52.

The gouge is turned on the tool rest so that it will be inclined in the direction that it will move. The grind is tangent to the work, and the center point of the cutting edge is the contact point with the wood. As the cut progresses toward and around the end of the curve, the handle is gradually raised and swiveled to the right (Fig. 53) in order to maintain the tangency between the grind and the surface being cut .

Figs. 54 and 55 show the cutting of a long taper with a skew.

The operation differs from smoothing a cylinder only at the start of the cut. The starting cut should be made with the heel (Fig. 54) to prevent the tool from digging into the work. As the tool moves down the work, the chisel can be pulled back to allow the center point of the cutting edge to cut. However, the full taper can be made with the heel. Be careful not to cut too deeply at the center of the taper. The direction of cutting is always downhill.

COVE CUTS
Second to forming a perfect bead, the cove or concave cut is the most difficult to master. This cut is made with the gouge, where the size of the tool depends on the size of the cut. Push the gouge directly into the work to remove the surplus stock (Fig.56).

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. From the starting position, push the gouge into the revolving stock, and roll the tool on the rest. A triple action takes place here. (1) The chisel will roll to follow the shape of the cut, (2) the handle will drop slightly so that the portion already cut will force the lip of the chisel sideways and, (3) the chisel will be pushed for- ward so that at the end of the cut, Fig. 58, it will be well up on the work and tangent with the cut surface.

Make only one-half of the cut at a time, then reverse the chisel to cut the other half. The occasional turner should make cove cuts with a scraping technique, using either the small gouge or round nose chisel.

SQUARE SECTIONS
When the turning has a square section, joint the stock before turning. Good centering is essential since any error will show at the shoulder where the round meets the square. Turning of the shoulder from square to round can be done in various ways. If the parting tool is sharp, the nicking cut with skew (Fig. 59) can be omitted.

The final trimming operation (Fig. 62) can be done with either the skew, spear chisel, or gouge, and is a scraping operation. While the shoulder can be cut with the same technique used for cutting a bead, the simpler scraping method pictured does clean work and is easier to do.

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 turning area slightly oversized to eliminate heavy roughing cuts in turning. When using the faceplate, tighten the faceplate locking screw (A) Fig. 23 to avoid personal injury or damage to the machine.

MOUNTING WORK TO FACEPLATE
Fig. 63 shows direct mounting to the 4” faceplate along with attaching to the backing block. Because of the ease of setting up, use this mounting whenever the work permits. Hold larger pieces in the same way by using the 8” face- plate. When normal screw-fastenings interfere, mount the work on a backing block (Fig. 63).

When screws are not permissible at all, glue the work to the backing block by fitting a sheet of paper at the joint to allow later separation without damaging the wood. Some work can be screwed or nailed from the face side into backing block. Mount work less than 4” in diameter on the single screw center (Fig. 64).

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. Loosen the set screw on the faceplate (A) Fig. 66 two full turns. Use the supplied wrench (B) Fig. 67 to loosen the face plate, then remove the faceplate from the spindle.
6. Use an outboard tool rest (B) Fig. 68 for all outboard turnings.
7. Fig. 69 illustrates the correct method for outboard turnings.
