3.0 Safety warnings

1. Read and understand entire owner's manual
before attempting assembly or operation.

2. Read and understand the warnings posted on
the machine and in this manual. Failure to
comply with all of these warnings may cause
serious injury.

3. Replace warning labels if they become
obscured or removed.

4. This lat he is designed and intended f or use by
properly trained and experienced personnel
only. If you a re no t fa miliar with the pro p er a nd
safe operation of a lathe, do not use until
proper training and knowledge have been
obtained.

5. Do not use this lathe for othe r than its intended
use. If used for other purposes, Powermatic
disclaims any real or implied warranty and
hold s itself harmles s from a ny injury t hat may
result from that use.

6. Always wear approved safety glasses or f ace
shields while using this lathe. Everyday
eyeglasses only have impact resistant lenses;
they are not safety glasses.

7. Before operating this lathe, remove tie, rings,
watches and other jewelry, and roll sleeves up
past the elbows. Remove all loose clothing
and confine long hair. Non-slip footwear or
anti-skid floor strips are recom mended. Do not
wear gloves.

8. Wear ear protectors (plugs or muffs) during
extended periods of operation.

9. Some dust created by power sanding, sawing,
grinding, drilling and other construction
activities contain chemicals known to cause
cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:

• Lead from lead based paint.

•

Crystalline silica from bricks, cement and
other masonry products.

•

Arsenic and chromium from chemically
treated lumber.

Your risk of exposure varies, depending on
how often you do this type of work. To reduce
your exposure to these chemicals, work in a
well-ventilated area and work with approved
safety equipment, such as face or dust masks
that are specifically designed to filter out
microscopic particles.

10. Do not operate this machine while tired or
under the influence of drugs, alcohol or any
medication which may impair your judgment.

11. Make certain switch is in OFF position before
connecting machine to power supply.

12. Make certain machine is properly grounded.

13. Make all machine adjustments or maintenance
with machine unplugged from power source.

14. Remove adjusting keys and wrenches. Form a
habit of checking to see that keys and
adjusting wrenches are removed from the
machine before turning it on.

15. Keep safety guards in place at all times when
machine is in use. If removed for maintenance
purposes, use extreme caution and replace
the guards immediately after completion of
maintenance.

16. Check damaged parts. Before further use of
the machine, a guard or other part that is
damaged should be carefully checked to
determine that it will operate properly and
perform its intended function. Check for
alignment of moving parts, binding of moving
parts, breakage of parts, mounting and any
other conditions that may affect its operation.
A guard or other part that is damaged should
be properly repaired or replaced.

17. Provide for adequate space surrounding work
area and non-glare, overhead lighting.

18. Keep floor around machine clean and free of
scrap material, oil and grease.

19. Keep visitors a safe distance from the work
area. Keep children away.

20. Make your workshop child proof with padlocks,
master switches or by removing starter keys.

21. Give your work undivided attention. Looking
around, carrying on a conversation and “horse­play” are careless acts that can result in
serious injury.

22. Maintain a balanced stance at all times so that
you do not fall against t he spindle, workpiece
or other moving parts. Do not overreach or use
excessive force to perform any machine
operation.

23. Use the right tool at the correct speed and
feed rate. Do not force a tool or attachment to
do a job for which it was not designed. The
right tool will do the job better and more safely.

24. Use recommended accessories; improper
accessories may be hazardous.

25. Keep turning tools sharp and clean for the best
and safest performance, and position tools
properly in relation to the workpiece.

5



26. Turn off the machine before cleaning. Use a
brush or compressed air to remove chips or
debris — do not use your hands.

33. Make sure all locking handles are tight to
prevent creeping of headstock, tailstock or tool
post.

27. Do not stand on the machine. Serious injury
could occur if the machine tips over.

28. Never leave the lathe running unattended.
Turn the power off and do not leave the
machine until spindle stops completely.

29. Remove loose items and unnecessary work
pieces from the area before starting the
machine.

30. Don’t use in dangerous environment. Don’t
use power tools in damp or wet locatio ns, or in
the presence of flammable liquids or gases.

31. Check workpiece carefully for splits, knots or
other obstructions which may cause a safety
risk while turning.

32. Adjust tool support to proper height and
position for the work. Rotate workpiece by
hand to check clearance with tool support.

Familiarize yourself with the following safety notices used in this manual:

This means that if precautions are not heeded, it may result in minor injury and/or possible

machine damage.

34. Turn off lathe before adjusting tool rest.

35. S elect appropriate speed for the turning job at
hand. Start at low speed and allow lathe to
ramp up to operating speed.

36. Never stop a rotating workpiece with your
hand.

37. If reversing spindle rotation, make sure face
plate or vacuum chuck is secured with t he set
screws.

7.10 Optional accessories

The following items are optional and purchased
separately. See your Powermatic dealer for
information. If you did not purchase an optional
accessory, proceed to section 7.11.

The optional 20-inch bed extension is available in
two configurations: Bed Extension only (p/n

6294905) and Bed Extension Kit with elevating and
swing-away function (p/n 6294900). The bed
extension can be installed to upper or lower sets of
holes.

7.10.1 20-inch Bed Extension

Installing Bed Extension only (p/n 6294905)

Tools required:
10mm hex key

1. Slide tailstock away from edge of bed.

2. Have an assistant hold bed extension flush to
end of lathe bed, and insert f our screws with
washers (provided with bed extension). Snug
screws just enough to hold bed extension to
lathe bed.

Figure 12

4. Install support bracket (E, Figure 13) with
knurled screw. This prevents adaptor from
backing out during spindle rotation.

3. Adj ust extension bed to lathe bed, aligning the
surface and the inside ways as closely as
possible.

IMPORTANT: Top surface of bed extension
must be flush with surface of lathe bed, and

inside ways must be aligned, to allow smooth
movement of tailstock across joint.

4. Slide tailstock over joint where beds meet, so
that clamping nut is centered over joint (Figure

14). Lock tailstock clamping handle; this will
align the beds.

5. Tighten screws in extension bed.

6. Unlock tailstock and slide it back and forth to
test smoothness of joint.

10mm hex ke y
Strai ght Edge

1. Slide tailstock away from edge of bed.

2. Place a straight edge against bed and raised
area of leg (Figure 16). These two areas
should be flush. If they are not, support the
lathe (with fork lift, hoist, etc. – USE
CAUTION!) and loosen the screws holding leg
to bed. Nudge leg as needed, then retighten
screws firmly.

3. Install 20-inch bed extension in the same
manner as described in section 7.10.1.

Figure 16

4. Install elevating system (Figure 17) to bed
extension with four 3/8" screws and washers,
and to lathe leg with three 1/2” screws and
washers (A, Figure 17). Note that top screw is
installed from inside the leg and secured with
the nylon nut (B). Refer to exploded view,
section 17.5.1 if clarification is needed.

5. Install handwheel and tighten setscrew.

Figure 17

Remove screws in bed extension to swing away
the bed, or to move bed to lower set of holes. Note:
If heavy loading makes handwheel turning difficult,
a 19mm wrench can be used to turn hexagonal
shaft (Figure 18).

For outboard turning, where headstock is moved to
opposite end of lathe to accommodate large bowl
blanks, you can (1) mount the 20-inch bed
extension to the lower set of holes on the Lathe
frame, and (2) mount an extension post [included
with kit] to the tool rest base. See Figure 19.

For larger outboard work, an outboard turning
stand (# 6294732) is available; see section 13.0,

Dead blow mallet (or hammer with wood block)

The optional 63-inch bed extension with leg
assembly is mounted to the upper set of holes in
similar fashion to the 20-inch bed extension. Install
leg first, level with leveling feet, then attach to
lathe.

7.11 User-made shelf assembly

The double ledges inside the lathe legs provide
support for a shelf (not provided), which is
convenient for storing larger items while keeping
them easily accessible.

Figures 20/21/22 illustrate three methods of
creating a shelf, using common lumber and basic
tools.

IMPORTANT TIP: It is unlikely that a full-size shelf
can be completely built and then inserted between
the Lathe legs. Therefore, construct the shelf in

Figure 20

Figure 21

Shelf Style 3: (Figure 22)
This is a basket-style shelf consisting of two 2x6’s

and dowel rods. The advantage of this design is
that most wood chips will fall through the shelf
instead of accumulating on it. The instructions
below are for building the shelf shown in Figure 22.

15



Figure 22

Materials used:

2 – 2x6’s (cut to length).
10 – wood dowels, 4’ length, 5/8” diameter.

1. Mark your hole centers (2” centers) along the
length of a 2x6. Place the holes so that the
tops of the dowels will be even with the tops of
the ledges on the Lathe. Also, adj ust your hole
centers as necessary so that the first and last
dowel will begin at approximately the same
distance from the ledge at both ends of the
Lathe.

2. Use a 5/8” spade bit chucked in a drill press or
in a portable drill. Bore t he holes through one
2x6; this will be the rear piece.

3. On the other 2x6, do not bore through b ut only
deep enough to securely hold the ends of the
dowel rods. This will be the front piece and will
provide a pleasing appearance at the front of
your Lathe.

4. When all holes have been bored, place the
2x6’s on edge in the outer ledges of the Lathe.

5. Cut the dowel rods to length with a miter saw
or hand saw, so that after insertion the rods
will be flush with the back of the rear 2x6.

6. Insert the dowel rods through the holes in the
rear 2x6, as shown in Figure 22.

7. A strip of wood can be screwed to the rear 2x6
to cover the dowel holes and prevent the
dowels from working out.

8.0 Electrical connections

Electrical connections must be
made by a qualified electrician in compliance with
all relevant codes. This machine must be properly
grounded to help prevent electrical shock and
possible fatal injury.

The 4224B Lathe will operate on single phase or
three phase, 230 volt power supply.

Make sure th e characteristics of your p ower supply
match the power specifications on the lathe
inverter.

Before connecting to power source, be sure switch
is in o ff position.

It is recommended that the lathe be connected to a
dedicated 20 amp circuit with a 20 amp circuit
breaker or time-delay fuse marked “D”. Local
codes take precedence over recommendations.

8.1 Single phase operation

A three wire pigtail for use on 230 volt single phase
power is attached to the inverter and may be “hard­wired” to the power source, or connected to a
UL/CSA listed receptacle plug.

Connect the 230 volt supply to the black and white
leads and ground the green lead.

If you are hard-wiring the Lathe to a panel, make
sure a disconnect is available for the operator.
During hard-wiring of the Lathe, make sure the
fuses have been removed or the breakers have
been tripped in the circuit to which the Lathe will be
connected. Place a warning placard on the fuse
holder or circuit breaker to prevent it being turned
on while the machine is being wired.

8.2 Three phase operation

If three phase power is used, it will be n ecessary to
replace the pigtail wire attached to the inverter with
a 12/4 wire and connect the three hot leads to the
inverter at R, S, T as sho wn in the wiring diagram
in section 18.0. Always connect the ground lead.

8.3 Variable frequency drive

The lathe uses a Variable Frequency Drive – also
called an A.C. Inverter – to provide infinitely
variable spindle speeds within the specified
ranges. The inverter controls the speed of the
motor by varying the frequency of the voltage
supplied to the motor. The inverter provides an
accelerati on ramp that eliminates the sho ck of
normal starting. Also, a braking feature eliminates
long coasting periods after the lathe is turned off.

The 3-horsepower motor is specially designed for
use with inverter drives, and is balanced to reduce
noise and minimize vibration.

16



The inverter does not require any programming; it
has been pre-programmed from the factory. The

buttons on the face of the inverter should never
be pushed at any time. Use only the controls on

the front of the headstock.
If you suspect a problem with the inverter or its

settings, contact Powermatic technical service at 1­800-274-6846.

A lightning strike or power surge
may cause the inverter to fail. When lathe is not in
use, disconnect power plug, or have a 3- or 4-pole
disconnect installed on the power side.

8.4 Extension cords

An extension cord is not recommended; try to
position equipment within reach of the power
source. If an extension cord becomes necessary,
be sure it is heavy enough to c arry the current your
product will draw. An undersized cord will ca use a
drop in line voltage resulting in loss of power and
overheating.

Table 1 shows recommended size to use
depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the cord.

To remove headstock, tailstock or toolre st base
from bed, unscrew and remove either of the stop
bolts (see B, Figure 3). After remounting these
items on the Lathe, reinstall stop bolt(s).

For most turning operations, except outboard
turning, the headstock should be positioned at left
end of bed, and only the tailstock moved to
accommodate the workpiece.

9.2 Cam tightness

If headstock, tailstock or tool rest base does not
tighten properly against bed when locking handle is
tightened, it may need adjusting. Figure 24 uses
tailstock as example:

1. Remove stop bolt on end of lathe bed, and
slide tailstock off.

2. Turn tailstock on its side, and slightly tighten
lock nut with a wrench. (Headstock has two
nuts.)

3. Mount tailstock on bed and verify adjustment.
Repeat as needed.

4. Reinstall stop bolt.

9.0 Adjustments

9.1 Headstock/tailstock movement

To slide headstock, loosen locking cams at rear
(see A, Figure 3) with provided wrench. Always
retighten cams before operating lathe.

To slide tailstock, swing locking h andle (B, Figure

23) to upright position. Push lockin g h andle forward
or back to tighten tailstock in place.

9.3 Tool support

9.6 Indexer

A 14” tool support is provided with your lathe. It is
designed to allow adjustment for height, position on
the bed, and angle to the work.

Loosen locking handle on tool support base (C,
Figure 25) to slide support base forward or back,
and to angle it to the bed. Tighten locking handle
firmly before operating lathe.

Loosen handle (D, Figure 25) to raise or lower tool
support and angle it to the work. Tighten handle
before operating lathe. If tool rest post begins to
slip, tighten screw (E, Figure 25).

Figure 25

9.4 Locking handles

Locking handles, such as D, Figure 25, are
adjustable. Simply lift out on handle, rotate it on the
pin, then release it, making sure it seats itself on
the pin.

9.5 Live center and cone

The live center cone, shown in Figure 26, screws
clockwise onto the threads of the live center body.

The indexer is used to create evenly spaced
features in a workpiece, while keeping the lathe
spindle locked; for example, when cutting flutes on
a spindle blank with a router, while the spindle
blank is secured between lathe centers.

Index positions are inscribed on the spindle,
ma t c hing hol e locations o n t he handw he el.

To use indexer (Figure 27):

1. Loosen handle (A) and position arm until
indexer pin aligns with the desired array of
holes.

Figure 27

2. Rotate spindle to position b y observing sca le
on spindle.

3. P ush i ndex er k nob unti l pi n ent ers handw hee l
hole. Rotate indexer knob to engage threads
and secure handwheel.

NOTE: Tighten indexer knob only enough until
pin fully engages hole and spindle will not turn.
Do not overtighten, as this could cause slight
def le c t ion i n t he spind le .

4. Perform the operation upon the workpiece.

Figure 26

To remove cone from live center, first insert live
center pin through hole in live center body as
shown in Figure 26. If pin will not insert at first,
rotate cone until pin can be inserted. The cone can
now be removed by holding body stationary while
unscrewing cone.

5. Unscrew knurled knob until indexing pin
releases; turn handwheel to next indexing
position, and re-engage indexing pin.

IMPORTANT: Release index pin before turning on
lathe.

The indexer assembly can be removed from the
lathe by lo osening and removing locking handle (A,
Figure 27).

center should first be mounted to your
workpiece; see section 11.4), clean tapered
end of center and inside of headstock taper
spindle, then push center into headstock
spindle.

3. To remove a spur center or live center, first
remove workpiece from lathe. Insert knockout
rod (F ig ure 28 ) t hr o ug h ho le i n ha nd whe e l a nd
firmly tap the tapered end of spur center. The
sliding collar on the knockout rod helps give
the necessary impact without having to use a
mallet against the end of the rod.

IMPORTANT: Hold the center by either
placing your thumb and forefinger on outside
diameter of spur center, or wrapping center
with a rag. The center can be damaged if
allowed to fall.

screws. Engage spindle lock, and turn face

plate counterclockwise with face plate wrench.

9.10 Vacuum chuck:

Installing/removing

1. Disconnect lathe from power source.

2. Lock spindle.

3. Install vacuum chuck onto threads of
headstock spindle and rotate clockwise hand­tight. When lathe is turned on (forward
rotation), the rotational force will snug the
vacuum chuck even further onto the thre ads.

4. Make sure vacuum adaptor is inserted into
handwheel, and air supply is connected. Turn
on air system and place workpiece against
vacuum chuck.

If at any time you will be

reversing spindle rotation, make sure the set
screws in the vacuum chuck are tight! Failure
to do this may cause vacuum chuck to loosen
from headstock spindle.

5. To remove vacuum chuck, turn off air supply,
and loosen the two set screws. Engage
spindle lock, and turn vacuum chuck counter­clockwise with face plate wrench.

9.8 Spindle lock

1. Push spindle lock button (see G, Figure 33),
and rotate spindle slightly until button goes
entirely into recess. Slide plate down over
button.

2. Rot at e spi nd le b y ha nd until it loc k s.

3. Slide plate upward to release spindle.

IMPORTANT: Always release spindle lock before
turning on lathe.

9.9 Face plate: Installing/removing

1. Disconnect lathe from power source.

2. Mount face plate to your bowl blank.

3. Lock spindle.

4. Install face plate onto threads of headstock
spindle and rotate clockwise hand-tig ht. When
lathe is turned on (forward rotation), the
rotational force will snug the face plate even
farther onto the threads.

5. Face plate is now ready for turning.

9.11 Comparator

The spindle comparator consists of two comparator
centers inserted into the brackets at rear of lathe.
The comparator is used to mount a finished, or
“reference” spindle, from which measurements can
be taken, the measurements being transferred to
the new piece being turned.

Guard must be removed to

use spindle comparator. Use caution and wear
a face mask when turning without guard
installed.

1. Remove guard from bracket and swing lamp
holder away.

2. Install comparator spur center into guard
bracket, by lifting up on plunger a nd inserting
comparator spur center until its point is about
even with the point of the spur center in the
headstock spindle. See Figure 29. The plunger
in the bracket should engage one of the holes
in the comparator center at this position.

3. Install comparator dead center in the
comparator bracket and tighten lock handle.
See Figure 30.

4. Mount spur center with the spindle blank that
you will be turning. Loosen tailstock locking
handle, and slide tailstock until live center is
about 1-inch from spindle blank, then tighten
locking handle. Advance live center using
tailstock handwheel, until live center is secured
in spindle blank.

5. Mount reference spindle between comparator
centers, as shown in Figure 30.

NOTE: Reference spindle should be mounted
last after all adjustment of tailstock and quill
has been accomplished with spindle blank.
Likewise, when turning operation is complete,
remove reference spindle first.

5. Loosen lock handle (A) and lower motor to
tension belt. Be sure that the Poly-V grooves
of the belt seat properly in corresponding
groove of sheave. Do not overtension; a very
light pressure on the tension handle (B) is
adequate to prevent belt slippage.

6. Tighten lock handle (A).

9.13 Checking spindle play

The spindle bearing has been set at the factory for
general turning applications. There should be no
"end play" or looseness along the spindle’s axis. If
any looseness should ever occur, it may be
rectified by carefully tightening the bearing lock nut
on the spindle, as follows. (See Figure 32).

1. Loosen set screws and remove handwheel
from headstock.

2. Use a screwdriver to carefully bend back any
tabs on the tabbed lock washer (C, Figure 32)
that interfere with the insets on the bearing
lock nut (D).

3. Place the end of a flat head screwdriver down
against one of the insets of the bearing lock
nut (D).

Figure 30

9.12 Speed change

1. Disconnect lathe from power source.

2. Open belt access door.

3. Loosen lock handle (A, Figure 31) and lift up
hand le ( B) to ra ise mo tor . T ight e n loc k hand le
(A) to hold motor in raised position.

4. There should be sufficient slack in the belt to
reposition it to the other steps on the sheaves.
The label on the access door shows the
required belt position.

4. Tap the handle of the screwdriver with a mallet
so that it turns the bearing lock nut (D) tighter
in a clockwise direction. Rotate the bearing
lock nut only about 1/16” at a time.

Do not over-tighten the

bearing lock nut or the spindle bearings may
overheat during operation.

20



Figure 32

5. The bearing lock nut should be tightened just
enough to remove end play, and spindle
should still rotate freely. Run the lathe for a
time, and check for heat from the spindle
bearings. If the bearings are running hot, the
bearing lock nut is too tight and should be
loosen ed slightly.

NOTE: You may have to tap the end of the
spindle with a wood block to move it. (Never
use a steel face hammer directly against the
spindle.)

6. After the bearing lock nut (D) has been
properly adjusted, carefully bend back into
place any tabs on the tabbed lock washer (C).

7. Rein st all ha ndw he el and tighte n set sc r e w s.

9.14 Sheave and belt alignment

The motor and spindle sheaves are aligned with
each other at the factory, but if any service is
performed that affects their alignment it is very
important that they be realigned. To realign them,
loosen the two set screws on the spindle sheave
(E, Figure 33) with a hex key, and slide spindle
sheave into proper position. Re-tighten set screws.

When sheaves and belt are properly aligned, there
should be no unusual pulsing sounds or noise
coming from the belt.

9.15 Sheave/drive belt replacement

Replacing the spindle sheave can be a difficult
procedure; it is recommended that the headstock
be taken to an authorized service center for this.

See Figure 33.

1. Disconnect lathe from power source.

2. Loosen lock handle (A) and lift up handle (B)
to raise motor.

7. If replacing spindle sheave, loosen two set
screws (E, Figure 33), and slide sheave off
spindle.

8. Install new spindle sheave, loosely securing
the two set screws. Make sure the sheave is
oriented properly.

9. Slide spindle back into place, install tabbed
lock washer, and bearing lock nut (C/D, Figure

32). Check for any spindle play at this point
(See section 9.13, “Checking Spindle Play”).

10. Reinstall handwheel and tighten set screws (F,
Figure 33).

11. Align new sheave (see section 9.14, “Sheav e
and Belt Alignment”) then tighten two set
screws (E, Figure 33) securely on sheave.

12. Loosen lock handle and allow motor to lower.
Do not overtension; a very light pressure on
the tension handle is adequate to pre vent belt
slippage.

Figure 34

11.0 Operation

The information which follows is general in nature
and not intended to be a complete course in
woodturning. Nothing can replace the knowledge
gained by talking with experienced woodturners or
consulting books or trade magazines. Above all,
simple trial and error will aid in developing
proficiency in the craft.

11.1 Inspection

Before operating the lathe, check that everything is
in proper working order:

1. Level your machine; use the leveling feet to
help reduce vibration.

2. Check bearings; adjust only if endplay exists.

3. Check belt; it should be snug but not overly
tight.

4. Bed ways; keep clean, use steel wool to
remove any rust spots, and apply paste wax to
prevent buildup of rust and finishes.

5. Tool support; use a mill file to remove nicks
and dings.

6. Spindle tapers; should be clean and free of
dust and chips for proper seating of tapers.

7. Tailstock; clean and lubricate quill and locking
device.

8. Lighting; proper lighting is essential to
eliminate shadows and reduce eye strain.

11.2 Turning Tools

If p ossible, select only quality, high-speed steel
turning tools. High-speed steel tools hold an edge
and last longer than ordinary carbon steel. As one
becomes proficient in turning, a variety of specialty
tools for specific applications can be acquired. The
following tools provide the basics for most
woodturning projects (see Figure 35):

Skews – 1-1/2" and 1" or 1-1/4", used to make
finishing cuts and details.

Large Roughing Gouge – 1" to 1-1/4", used to
eliminate waste wood.

Spindle Gouges – 1/4", 3/8", 1/2", used to turn
beads, coves and other details.

Deep Fluted Bowl Gouge – 1/4", 3/8" an d 1/2",
used for turning bowls & plates.

Square Scraper (Bedan) – 3/8” or 1/2", used to
create square shoulders.

Large Round Nose (Domed) Scraper – 1-1/2",
used to reduce ridges on interior of bowls, round
edges of bowls, etc.

Parting Tool - 1/8", used for scraping, making a
cut-off, or to set diameters for sizing.

22



Figure 35

Basic Turning Tools

For safety and best performance, keep tools sharp.
If a tool stops cutting or requires excessive
pressure to make a cut, it needs to be sharpened.
A number of brand name sharpening jigs and
fixtures are available; however, a woodturner
should learn to sharpen tools freehand.

For best results, use a slow speed grinder (1800
rpm) fitted with a 60-grit aluminum oxide wheel (for
shaping) and a 100-grit alum. oxide wheel (for final
sharpening and touchup). The grinder should be
located near your lathe and at a comfortable
height. A diamond dresser will keep the wheels
true and eliminate glazing.

Never allow the tool to rest in one place on the
wheel, keep it moving and use a light touch.

Carbon steel tools can overheat easily and should
be cooled frequently. If the edge turns blue, it has
lost its temper and should be ground past the blue
area. High-speed steel tools are not as likely to
overheat, but can be damaged if allowed to get red
hot. High-speed steel tools should not be
quenched for cooling. Honing with a diamond lap
or slipstone will save trips to the grinder and keep
the edge fresh.

11.3 Spindle Turning

Spindle turning takes place between the centers of
the lathe. It requires a spur or drive center in the
headstock and a live or dead center in the tailstock.
A cup center rather than a cone center in the
tailstock will often reduce the risk of spli tting the
stock.

Figure 36 shows the basic profile shapes in spindle
turning.

Figure 36

11.4 Stock Selection

Stock for spindles should be straight grained and
free of checks, cracks, knots and other defects . It
should be cut 1/8" to 1/4" larger than the finished
diameter and may require additional length so the
ends can be removed later. Larger stock should
have the corners removed to produce an octagon
making the piece easier to rough down to a
cylinder.

1. With a combination square, or plastic center
finder for round stock, locate and mark center
on each end of the workpiece. Accuracy is not
critical on full rounds but extremely important
on stock where square sections are to remai n.
Put a dimple in the stock with an awl or nail, or
use a spring-loaded automatic center punch.

2. Extremely hard woods may require kerfs cut
into the ends of the stock (Figure 37) using a
band saw, so the wood will accept the spur
center and the live center.

Figure 37

3. Drive the spur center about 1/4” into the
workpiece, using a wood mallet or dead b low
hammer as shown in Figure 38. Be careful that
you do not split the workpiece. Never use a

steel face hammer and never drive the
workpiece onto the spur center while it is
mounted in the Lathe spindle.

4. Make sure headstock is locked to lathe bed.

5. Clean tapered end of spur center and inside of
headstock spindle.

6. Insert tapered end of spur center (with the
attached workpiece) into headstock spindle.

7. Support the workpiece while bringing the
tailstock into position about 1-inch away from
end of workpiece. Lock tailstock to bed.

8. Advance tailstock quill with the handwheel in
order to seat the live center into the workpiece.
Use enough pressure to secure the workpiece
between the centers so that it won’t f ly off, but
do not use excessive pressure.

9. Tight en quill lo c king ha ndle .

The tailstock quill is capable

of exerting excessive pressure against the
workpiece and the headstock. Apply only
sufficient force with tailstock to hold workpiece
securely in place. Excessive pressure can
overheat center bearings and damage both
workpiece and lathe.

11.5 Cutting Techniques

11.5.1 Roughing Out

1. Begin with a large roughing gouge. Place t he
tool on the tool support with the heel of the tool
on the surface to be cut.

2. Slowly and gently raise tool handle until cutting
edge comes into contact with the workpiece.

3. Beginning about 2” from the tailstock end of
the workpiece, roll the flute (hollowed-out
portion) of the tool in the direction of the cut.
See Figure 40. Make lo ng sweeping cuts in a
cont in uous m otio n to r oug h the p iece down t o
a cylinder.

4. Keep as much of the bevel of the tool as
possible in contact with the workpiece to
ensure control and avoid catches. NOTE:
Always cut down-hill, or from large diameter to
small diameter. Always work toward the end of
a work-piece, never start cutting at the end.

10. Move tool support into position. It should be
parallel to workpiece, just below the centerline
and approximately 1/8" to 1/4" from the
corners of the workpiece to be turned, as in
Figure 39. Tighten support base to Lathe bed.

11. Rotate workpiece by hand to check for proper
clearance.

12. Start lathe at lowest speed and bring it up to
the appropriate RPM for the size of work piece
used. Consult digital readout on the
headstock.

Figure 40

5. Once the workpiece is roughed down to a
cylinder, smooth it with a large skew. Keep t he
skew handle perpendicular to the spindle and
use only the center third of the cutting edge for
a long smoothing cut (touching one of the
points of the skew to the spinning workpiece
may cause a catch and ruin the workpiece).

6. Add details to the workpiece with skew, parting
tool, scraper or spindle gouge.

24



11.5.2 Beads

1. Make a parting cut for what is to be a bead to
the desired depth. Place the parting tool on the
tool support and move tool forward to make
the full bevel of the tool come into contact with
the workpiece. Gently raise handle to make cut
to the appropriate depth.

2. Repeat for other side of the bead.

3. Using a small skew or spindle gouge, start in
the center between the two cuts a nd cut down
each side to form the bead. Roll the tool in
direction of cut.

11.5.3 Coves

1. Use a spindle gouge. With the flute of the tool
at 90 degrees to the workpiece, touch the point
of the tool to the workpiece and roll in toward s
the bottom of the cove. See Figure 41. Stop at

the bottom; attempting to go up the
opposite side may cause the tool to catch.

Figure 42

5. Repeat f rom the left side. T he two cuts should
meet at the bottom and leave a clean "V" cut.

6. Additional cuts may be taken to add to eit her
the depth or width of the cut.

11.5.5 Parting Off

1. Use parting tool.

2. Adjust lathe speed to lower RPM for parting
through a workpiece.

3. Place tool on tool support and raise the handle
until it starts to cut and continue to cut toward
center of workpiece.

4. Loosely hold on to the piece in one hand as it
separates from the waste wood.

Figure 41

2. Move the tool over the desired width of the
cove.

3. With the flute facing the opposite direction,
repeat step 1 for other side of cove. Stop at
bottom of cut.

11.5.4 "V" Cuts

1. Use the long point of the skew. (NOTE: Do not
press the long point of the skew directly into
the workpiece to create the "V"; this will result
in a burned or burnished "V" with fibers bei ng
rolled up at both sides.)

2. Lightly mark the center of the "V" with the tip of
the skew.

3. Move the point of the skew to the right half of
the desired width of your cut.

4. With the bevel parallel to the right side of the
cut, raise the handle and push the tool in to the
desired depth, as shown in Figure 42.

11.5.6 Sanding and Finishing

Leaving clean cuts will reduce the amount of
sanding required. Move the tool support out of the
way, adjust the lathe to a low speed, and begin
with fine sandpaper (120 grit or finer). Coarser
sandpaper will leave deep scratches that are
difficult to remove, and dull crisp details on the
spindle. Progress through each grit without
skipping grits (for example, do not jump from 120
grit to 220 grit). Fold the sandpaper into a pad; do
not wrap sandpaper around your fingers or the
workpiece.To apply a finish, the workpiece can be
left on the lathe.

Turn off lathe and use a brush or paper towel to
apply the finish. Remove excess finish before
restarting lathe. A llow to dry and sand again with
320 or 400 grit sandpaper. Apply second coat of
fin ish and buff.

11.6 Face Plate and Bowl Turning

Face plate turning is normally done on the inboard
side of the headstock over the bed. Larger
workpieces must be turned on the outboard side
(remove tailstock and tool support base, and slide
headstock to opposite end of bed).

25



11.6.1 Mounting Stock

Use of a face plate is the most common method for
holding a block of wood for turning bowls and
plates:

1. Select stock at least 1/8" to 1/4" larger than
each dimension on the finished workpiece.

2. Always select the largest diameter face plate
that can be used for the workpiece to be
turned.

3. True one surface of the workpiece for
mounting against the face plate.

4. Using the face plate as a template, mark the
location of the mounting holes on the
workpiece, and drill pilot holes of the
appropriate size. Face plates are drilled for No.
12 screws. (Phillips and square drive screws
will hold up better than slotted screws. Sheel
metal screws are case hardened with deeper
and sharper threads than wood screws.)

If the mounting screws on the face plate interfere
with the workpiece, a glue or waste block can be
used:

5. Make a block the same diameter as the face
plate, Figure 43. Both waste block and
workpiece should have flat surfaces for gluing.

6. Glue the block to the workpiece. Avoid using
brown paper or newspaper between the waste
block and workpiece. It may work fine if you
are using scrapers, but a slight catch with a
bowl gouge can separate the two.

NOTE: When using a waste block, be careful with
the adhesive you select. Dry workpieces can be
bonded with ordinary white or yellow glue but must
be clamped to ensure a good bond. Green
workpieces require cyanoacrylate type glue.

Figure 43

11.6.2 Faceplate or Chuck?

While faceplates are the simplest, most reliable
method of holding a block of wood for turning,
chucks can also be used. As there are dozens of
chucks to choose from, the woodturner sh ould first
consider all the different types of turning that will be
done, and read reports or discuss with other
turners who own chucks before making a decision.

A chuck is not a requirement, but is handy when
working on more than one piece at a time. Rather
than removing screws, you simply open the chuck
and change workpieces.

The most popular ones are four jaw scroll chucks
with a variety of jaws to accommodate different
size tenons. Most also come with a screw chuck as
well.

11.6.3 Wood Selection

Firewood is the cheapest, most widely available
stock to use while learning to turn bowls. Simply
waste wood for a while practicing turning
techniques. Develop skill with each tool before
attempting to make a finished piece. It is best to
start with dry wood, without worrying about drying
or distortion. Once turning becomes comfortable,
try green wood which cuts very easily. As the
turner gains experience, he or she will find
extraordinary grain and figure in the form of burls,
crotches and bark inclusions.

11.6.4 Checks and Cracks

Green wood will check and crack. For best results,
leave logs in as long a length as you can handle.
As the material starts to dry, surface cracks will
develop on the ends of the log. Cut off two to three
inches and you should find good, sound wood.
Also cut the log in half along the pith to avoid
having it in the finished piece. Most checks radiate
from the pith.

As you turn bowls from green wood, make sure
you maintain a consisten t wall thickness
throughout the piece. Leaving a piece thick in
some areas and thin in others will cause the wood
to dry unevenly and promote checks and cracks.

11.6.5 Distortion

Distortion is a problem associated with turning
green wood. It will vary from one type of wood to
the next. Typically, fruitwoods tend to distort more
than others. It also varies with the time of year the
tree was cut and how the logs are stored.

11.6.6 Tools for Bowl Turning

The deep fluted bowl gouge is the most essential
and versatile tool for most bowl and plate turning.
The bowl gouge is heavier and easier to control
than other types of gouges. It also allows removal
of wood much faster and with less vibration than
other gouges. Most average sized bowl work can
be accomplished with a 3/8" or 1/2" bowl gouge.

26



A 1/4" bowl gouge is best suited for smaller bowls
and light finishing cuts. Larger 3/4" and 1" bowl
gouges are only used for extremely large pieces.

Large domed scrapers can also be used to help
clean up the interior surfaces of bowls. A light
touch with the scraper sligh t ly tilted will eliminate
some of the ridges occasionally left by an
inexperienced bowl gouge.

11.7 Bowl Turning Techniques

11.7.1 To Shap e Out s ide of Bowl

1. Odd shaped burls, crotches and other irregular
shaped blanks require special preparation
before mounting in a chuck or onto a
faceplate. Remove the bark, if there is any,
from what appears to be the center of the top
of the workpiece.

2. Drive spur ce nter into the top of t he workpiece
with a mallet or dead blow hammer.

3. Slip the spur center into the headstock taper
and bring the tailstock with a live or ball
bearing center into position. Lock the tailstock
to the bed and advance the tailstock spindle in
order to seat the cup center into the
workpiece. Tighten the ram locking handle.

4. Turn workpiece by hand to ensure proper
clearance.

5. Start lathe at lowest speed and bring it up to
the maximum safe speed for the size of work
to be turned. If the machine starts to vibrate,
lower the speed until vibration stops.

6. Rough out the outside of the bowl with the 1/2"
deep fluted bowl gouge, holding the handle of
the tool firmly against your hip. For best
control, use your whole body to move the
gouge through the workpiece.

7. As the bowl takes shape, work on the bottom
(tailstock end) to accommodate attaching a
face plate.

8. Turn a short tenon (about 1/8" long) the size of
the hole in the faceplate. See Figure 44. This
will allow centering the workpiece when the
faceplate is attached.

(NOTE: If you plan to use a chuck, turn a
tenon of the appropriate length and diameter
to fit your chuck.)

9. Stop the lathe, remove workpiece and attach
face plate or chuck (see section 11.6.1

"Mounting Stock").

Figure 44

11.7.2 To Shape In terior of Bowl

1. Stop lathe and move tailstock away. (You may
want to remove the center from the tailstock to
avoid bumping it with your elbow.)

2. Adjust tool support in front of the bowl just
below centerline, at a right angle to the lathe
ways.

3. Rotate workpiece by hand to check clearance.

4. Face off top of bowl by making a light shearing
cut across the top of workpiece, from rim to
center.

5. Place 1/2" bowl gouge on tool support at
center of the workpiece with the flute facing
top of bowl. The tool handle should be level
and pointed toward the four o'clock position, as
shown in Figure 45.

Figure 45

6. Use the left hand to control cutting edge of
gouge, while right hand swings tool handle
toward your body (Figure 45). The flute should
start out facing top of workpiece, and rotate
upward as it moves deeper into the bowl to
maintain a clean even curve. As the tool goes
deeper into the bowl, progressively work out
toward the rim. It may be necessary to turn the
tool support into the piece as you get deeper
into the bowl.

The surfaces of faceplate

and workpiece should mount flush to each
other.

10. Finish turning the outside of bowl with 1/2" or
3/8" bowl gouge. Leave additional material at
base of bowl for support while turning interior.
This will be removed la ter.

(NOTE: Try to make one, very light continuous
movement from the rim to the bottom of the
bowl to ensure a clean, sweeping curve
through the piece.

Should there be a few small ridges left, a light
cut with a large domed scraper can even out
the surface.)

27



7. Develop wall thickness at the rim and maintain
it as you work deeper i nto the bowl (Once the
piece is thin toward the bottom, you cannot
make it thinner at the rim). When the interior is
finished, move the tool support to exterior to
re-define bottom of bowl. (General rule of
thumb: the base should be approximately 1/3
the overall diameter of the bowl).

8. Work the tight area around f aceplate or chuck
with 1/4" bowl gouge.

9. Begin the separation with a parting tool, but do
not cut all the way through yet.

11.7.3 Sanding and Finishing

1. Remove the tool support and adjust lathe
speed to approximately 500 RPM. Higher
speeds can build friction while sanding and
cause heat check in some woods.

2. Begin with fine sandpaper (120 grit) and
progress through each grit, using only light
pressure. Coarser sandpaper tends to leave
deep scratches that are hard to eliminate. Use
power-sanding techniques to avoid concentric
sanding marks around your finished piece.
Avoid rounding over the rim and foot with
sandpaper; try to keep details crisp. Finish
sanding with 220 grit.

3. Remove sanding dust with tack rags or
compressed air and, with lathe turned off,
apply first coat of finish. Let sta nd for several
minutes, wipe off excess. Allow to dry before
sanding again with 320 or 400 grit sandpaper.

4. Turn lathe back on and continue the
separation cut almost all the way through the
base. Stop at about 3" and use a small fine
tooth saw to separate the bowl from the waste.

5. Apply second finish coat and allow to dry
before buffing.

12.0 Maintenance

Before doing maintenance on
the lathe, disconnect it from electrical supply by
pulling out the plug or switching off main switch.
Failure to comply may cause serious injury.

Maintenance on the 4224B Lathe should be
performed at periodic intervals to ensure that the
machine is in proper working order, that all
fasteners are tight, and all necessary adjustments
have been made. Inspection and maintenance
should be performed at least twice a year, but
more frequently if the lathe receives constant use.

Clean and oil the lathe bed(s) so that headstock,
tailstock and tool support base will slide easily.
Clean any rust spots that may develop on the bed
with a commercial rust remover.

Use compressed air to blow out the interior of the
headstock, in order to keep sawdust and chips
from accumulating on belts and sheaves. Also blow
off debris that accumulates in the motor fan, and
on the inverter. Do not disassemble inverter to
clean!

Frequently clean out the morse tapers on both
headstock and tailstock. Commercially available
taper cleaners may be acquired from tool stores.
