manual before attempting assembly or  
operation.  
12. Make certain the switch is in the OFF position  
before connecting the machine to the power  
supply.  
13. Make certain the machine is properly  
grounded.  
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.  
14. Make all machine adjustments or maintenance  
with the machine unplugged from the power  
source.  
3. Replace the warning labels if they become  
obscured or removed.  
15. 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.  
4. This Lathe is designed and intended for use by  
properly trained and experienced personnel  
only. If you are not familiar with the proper and  
safe operation of a Lathe, do not use until  
proper training and knowledge have been  
obtained.  
16. Keep the safety guard in place at all times  
when the machine is in use. If removed for  
maintenance purposes or for turning  
procedures which do not permit its use,  
exercise extreme caution and replace the  
guard immediately after the operation is  
complete.  
5. Do not use this Lathe for other than its  
intended use. If used for other purposes,  
Powermatic disclaims any real or implied  
warranty and holds itself harmless from any  
injury that may result from that use.  
17. 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.  
6. Always wear approved safety glasses/face  
shields while using this machine. 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 recommended. Do not  
wear gloves.  
18. Provide for adequate space surrounding work  
area and non-glare, overhead lighting.  
8. Wear ear protectors (plugs or muffs) during  
extended periods of operation.  
19. Keep the floor around the machine clean and  
free of scrap material, oil and grease.  
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:  
20. Keep visitors a safe distance from the work  
area. Keep children away.  
21. Make your workshop child proof with padlocks,  
master switches or by removing starter keys.  
22. Give your work undivided attention. Looking  
around, carrying on a conversation and “horse-  
play” are careless acts that can result in  
serious injury.  
•
•
Lead from lead based paint.  
Crystalline silica from bricks, cement and  
other masonry products.  
Arsenic and chromium from chemically  
treated lumber.  
•
23. Maintain a balanced stance at all times so that  
you do not fall or lean against the centers,  
workpiece or other moving parts. Do not  
overreach or use excessive force to perform  
any machine operation.  
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.  
24. 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 safer.

25. Use recommended accessories; improper  
accessories may be hazardous.  
31. Check the workpiece carefully for splits, knots  
or other obstructions which may cause a  
safety risk while turning.  
26. Keep turning tools sharp and clean for the best  
and safest performance, and position the tools  
properly in relation to the workpiece.  
32. Adjust the tool support to the proper height  
and position for the work. Rotate the  
workpiece by hand to check clearance with the  
tool support.  
27. Turn off the machine before cleaning. Use a  
brush or compressed air to remove chips or  
debris — do not use your hands.  
33. Select the appropriate speed for the turning  
job at hand. Start at low speed and allow the  
Lathe to ramp up to operating speed.  
28. Do not stand on the machine. Serious injury  
could occur if the machine tips over.  
34. Never stop a rotating workpiece with your  
hand.  
29. Never leave the Lathe running unattended.  
Turn the power off and do not leave the  
machine until it comes to a complete stop.  
35. If gluing up a workpiece, always use a high-  
quality glue of the type necessary for that  
particular workpiece.  
30. Remove loose items and unnecessary work  
pieces from the area before starting the

8. Exposed metal areas of the Lathe, such as the  
bed and spindles, have been factory coated  
with a protectant. This should be removed with  
a soft cloth and a cleaner-degreaser. Clean  
the bed areas under the headstock, tailstock  
and tool support base. Do not use an abrasive  
pad, and do not allow solvents to contact  
painted or plastic areas.

disconnected from power during assembly.  
1. Remove any screws or straps that hold the  
Lathe parts to the pallet, and remove  
protective wrapping. Set all the boxes  
containing legs and accessories to the side.  
7.1 Tool caddy  
The tool caddy, shown in Figure 3, can be mounted  
to the left end or right end of the Lathe. The left  
end, near the headstock area, is generally  
preferred for convenience. Use two socket head  
cap screws and two lock washers with an 8mm hex  
wrench to secure the tool caddy to the threaded  
holes in the Lathe.  
2. Before assembling the legs, decrease the  
weight on the Lathe bed: Remove the stop bolt  
at each end of the bed, and slide off the  
headstock, tailstock and tool support base  
(Refer to sect. 9.1, Headstock and Tailstock  
Movement, for any clarification on removing  
these).  
The headstock is heavy; use  
caution when removing it from the lathe bed.  
3. Turn the lathe bed upside down on the  
shipping pallet (make sure there is nothing  
beneath that would scratch the bed ways).  
4. Install the legs to the bed using eight socket  
head cap screws with eight lock washers and  
eight flat washers (Figure 1). Tighten the  
screws firmly with an 8mm hex wrench.  
Figure 3  
The tool caddy has holes for placing the knockout  
rod, spur center, live center, live center pin,  
comparator centers, and faceplate wrench.  
Accessories can also be stored in the tailstock, as  
shown in Figure 4.  
Figure 1  
5. Screw the levelers into the threaded holes of  
the legs (Figure 1). Tighten the hex nuts  
against the bottom of the legs with a 14mm  
wrench. The levelers can be adjusted at any  
time to ensure the Lathe is stable and level.  
Figure 4  
6. Use an assistant to help stand the Lathe right  
side up on its legs.  
7.2 Guard  
7. The Lathe should be located in a dry area, on  
a sturdy floor, and with sufficient lighting.  
Leave plenty of space around the machine for  
operations and routine maintenance work.  
The guard must always be  
used in operations that will allow its use.

1. On the guard, loosen the set screw on the  
outer collar (shown in Figure 5) with a 4mm  
hex wrench. Slide the outer collar off the guard  
support rod.  
2. Have an assistant hold the bed extension flush  
to the end of the Lathe bed, and insert three  
3/8 x 1-3/4 socket head cap screws, three 3/8  
lock washers and three 3/8 flat washers,  
through the holes in the bed extension into the  
threaded holes on the Lathe. See Figure 7.  
Figure 5  
2. Insert the guard support rod into the mounting  
bracket at the rear of the headstock, as shown  
in Figure 5. You will have to lift up on the  
spring pin, as shown, to slide the guard  
support rod into the mounting bracket. Release  
the spring pin and it will snap into position as  
you slide the support rod farther in.  
Figure 7 (optional 18” bed extension shown)  
1. Adjust 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.  
3. Install the outer collar and tighten the set  
screw.  
2. Slide tailstock over joint where beds meet, so  
that clamping nut is centered over joint (Figure  
8). Lock tailstock clamping handle; this will  
align the beds.  
4. The guard can be pivoted to one of two  
positions: Operating mode (shown on front  
cover) or tilted back for stock loading (shown  
in Figure 6).  
5. Pull up on the spring pin, and begin tilting the  
guard, then release the spring pin. When the  
guard reaches either of the two positions, the  
spring pin will engage.

test smoothness of joint.  
7.3 Bed extension (optional accessory)  
5. Unscrew the stop bolt from the Lathe bed  
(Figure 7), and screw it into the hole at the end  
of the bed extension.  
An optional 18” bed extension assembly, stock  
number 6294727B, is available for the Lathe (see  
your Powermatic dealer). To mount the bed  
extension to the Lathe:  
1. Slide the tailstock away from the edge of the  
bed.

For outboard turning, where the headstock is  
moved to the opposite end of the Lathe to  
accommodate large bowl blanks, you can (1)  
mount the 18” bed extension to the three lower  
holes on the Lathe frame, and (2) mount a vertical  
extension post [included with the optional bed  
extension] to the tool rest base. See Figure 9.  
For large outboard work, an optional outboard  
turning stand (# 6294732) is available – see sect.  
16.4.1.  
Figure 10  
Figure 9  
(shown with optional accessories)  
7.4 Shelf assemblies (optional)  
Figure 11  
Shelf Style 3: (Figure 12)  
The double ledges on the inside of the Lathe legs  
will provide support for a shelf (not provided),  
which is convenient for storing larger items while  
keeping them easily accessible.  
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 12.  
Figures 10-11-12 illustrate three methods of  
creating a shelf, using common lumber and basic  
tools.  
Materials used:  
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  
pieces and insert screws only after the shelf has  
been established beneath the Lathe.  
2 – 2x6’s (33” suitable, 33-1/2” optimal).  
8 – 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, adjust 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.  
Shelf Style 1 (Figure 10)  
Lay two 2x6 boards flat upon the inner ledges.  
Boards of 33” length are suitable, although 33-1/2”  
is optimal.  
Shelf Style 2 (Figure 11)  
Lay two 2x4’s (or 2x6’s) on edge into the outer  
ledges. Boards of 33” length are suitable, 33-1/2”  
optimal.  
2. Use a 5/8” spade bit chucked in a drill press or  
in a portable drill. Bore the holes through one  
2x6; this will be the rear piece.  
Cut two pieces from a plywood board, and screw  
them to the top edges of the 2x4’s. (One 33”  
plywood piece will not fit through the legs of the  
Lathe; use at least two pieces.) Make the plywood  
pieces flush with the outside edge of the 2x4’s.  
3. On the other 2x6, do not bore through but 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.  
10

4. When all holes have been bored, place the  
2x6’s on edge in the outer ledges of the Lathe.  
Local codes take precedence over recommend-  
dations.  
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.  
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 “hard-  
wired” to the power source, or connected to a  
UL/CSA listed receptacle plug.  
6. Insert the dowel rods through the holes in the  
rear 2x6, as shown in Figure 12.  
7. A strip of wood can be screwed to the rear 2x6  
to cover the dowel holes and prevent the  
dowels from working out.  
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 necessary 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 shown in the wiring diagram  
in sect. 17.0. Always connect the ground lead.  
Figure 12  
8.3 Extension cords  
8.0 Electrical connections  
The use of extension cords is discouraged. Try to  
position machines within reach of the power  
source. If an extension cord becomes necessary,  
make sure the cord rating is suitable for the  
amperage listed on the machine’s motor plate. An  
undersized cord will cause a drop in line voltage  
resulting in loss of power and overheating.  
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.  
Use the chart in Table 1 as a general guide in  
choosing the correct size cord. If in doubt, use the  
next heavier gauge. The smaller the gauge  
number, the heavier the cord.  
This machine must be grounded. In the event of a  
malfunction or breakdown, grounding provides a  
path of least resistance for electric current to  
reduce the risk of electric shock.  
Recommended Gauges (AWG) of Extension Cords  
Extension Cord Length *  
Improper connection of the equipment-grounding  
conductor can result in a risk of electric shock. The  
conductor, with insulation having an outer surface  
that is green with or without yellow stripes, is the  
equipment-grounding conductor. If repair or  
replacement of the electric cord or plug is  
necessary, do not connect the equipment-  
grounding conductor to a live terminal.

9.0 Adjustments  
9.1 Headstock and tailstock  
movement  
To slide the headstock or tailstock, swing the  
locking handle (A, Figure 13) backward or forward  
until the headstock/tailstock can slide freely.  
When the headstock/tailstock is positioned, rotate  
the locking handle to tighten it securely.  
To remove headstock, tailstock or toolrest base  
from the bed, unscrew and remove either of the  
stop bolts (B, Figure 13). After re-mounting these  
items on the Lathe, re-insert the stop bolt.  
Figure 14  
For most turning operations, except outboard  
turning, the headstock should be positioned at the  
left end of the bed, and only the tailstock moved to  
accommodate the workpiece.  
9.3 Tool support  
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 the locking handle on the tool support base  
(C, Figure 15) to slide the support base forward or  
back, and to angle it to the bed. Tighten the locking  
handle firmly before operating the Lathe.  
Loosen the small handle (D, Figure 15) to raise or  
lower the tool support and angle it to the work.  
Tighten the handle before operating the Lathe.  
The small handle (D, Figure 15) can be inserted  
into one of three holes on the tool support base.  
The position shown in Figure 15 is preferred so  
that the locking handle contacts the groove in the  
tool rest shaft.  
Figure 13  
9.4 Locking handles  
(shown with optional spindle comparator bracket)  
Each small locking handle such as D, Figure 15  
can be rotated to a more convenient position.  
Simply lift up on the handle, rotate it on the pin,  
then release it, making sure it seats itself on the  
pin.  
9.2 Cam tightness  
If the headstock, tailstock or tool rest base does  
not tighten properly down against the Lathe bed  
when the locking handle is tightened, it may need  
adjusting. Figure 14 uses the tailstock as the  
example:  
1. Unscrew and remove the stop bolt on the end  
of the lathe bed (B, Figure 13) and slide the  
tailstock off the end of the bed.  
2. Turn the tailstock on its side, and tighten the  
lock nut with a wrench. See Figure 14.  
3. Mount tailstock on bed and insert the stop bolt  
at the end of the bed.

9.5 Live center and cone  
The live center cone, shown in Figure 16, screws  
clockwise onto the threads of the live center body.  
To remove the cone from the live center, first insert  
the live center pin through the hole in the live  
center body as shown in Figure 16. If the pin will  
not insert at first, rotate the cone until the pin can  
be inserted. The cone can now be removed by  
holding the body stationary while unscrewing the  
cone.  
Figure 18  
2. Unscrew and remove the index pin, and look  
down the hole, carefully counting the number  
of holes as you rotate the spindle using the  
handwheel. Continue to rotate the spindle until  
you reach the hole needed for your second  
flute cutting, then re-insert the index pin.  
3. Refer to the more detailed instructions and  
chart in sect. 13.0 to determine in which holes  
to place the index pin relative to the number of  
features desired in your workpiece.  
IMPORTANT: Remove index pin before turning  
on the Lathe!  
Figure 16  
9.6 Indexer  
9.7 Centers: installing/removing  
The indexer allows you to cut evenly spaced  
features in a workpiece while keeping the Lathe  
headstock spindle locked; for example, when  
cutting flutes on a spindle blank with a router, while  
the spindle blank is secured within the Lathe  
centers.  
1. Disconnect Lathe from power source.  
2. To install a spur center or live center (the spur  
center should first be mounted to your  
workpiece; see under “Operation” for more  
details), clean the tapered end of the center  
and the inside of the headstock taper spindle,  
then push the center into the headstock  
spindle.  
There are 12 holes in the spindle collar spaced 30°  
apart, and 4 holes in the headstock casting which  
accept the index pin (see Figures 17 and 18). The  
combination of holes will allow you to mark your  
workpiece for evenly spaced features.  
3. To remove a spur center or live center, first  
remove the workpiece from the Lathe. Insert  
the knockout rod (Figure 19) through the hole  
in the handwheel and firmly tap the tapered  
end of the 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.  
1. To use the indexer, thread the index pin  
(Figure 17) into one of the four holes until the  
index pin engages the spindle and prevents it  
from turning. This will be your first indexing  
position.  
IMPORTANT: Hold the center by either placing  
your thumb and forefinger on the outside diameter  
of the spur center, or wrapping the center with a  
rag. The center can be damaged if allowed to fall.

9.8 Face plate: installing/removing  
1. Disconnect Lathe from power source.  
2. Mount the face plate to your bowl blank.  
9.9 Speed change  
1. Disconnect Lathe from power source.  
2. To change speed ranges, pull open the access  
door on the headstock.  
3. Push in the spindle lock button (Figure 20) and  
rotate the handwheel slightly until the spindle  
locks. Keep the spindle lock button pushed in.  
3. Loosen the pivot lock handle (A, Figure 22)  
and lift up the tension handle (B, Figure 22) to  
raise the motor. Tighten the pivot lock handle  
(A, Figure 22) to hold the motor in the raised  
position.  
4. Install the face plate onto the threads of the  
headstock spindle and rotate clockwise hand-  
tight. When the Lathe is turned on (forward  
rotation), the rotational force will snug the face  
plate even farther onto the threads.  
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.  
If at any time you will be  
reversing spindle rotation, make sure the two  
set screws in the face plate are tight! One of  
these is shown in Figure 21. Failure to do this  
may cause the face plate to loosen from the  
headstock spindle.  
5. Loosen the pivot lock handle (A, Figure 22)  
and lower the motor to tension the belt. Be  
sure that the Poly-V grooves of the belt seat  
properly in the corresponding groove of the  
sheave. Do not overtension; a very light  
pressure on the tension handle (B, Figure 22)  
is adequate to prevent belt slippage.  
5. To remove the face plate, loosen the two  
socket set screws (Figure 21). Engage the  
spindle lock button and turn the face plate  
counterclockwise with the face plate wrench,  
as shown in Figure 21.  
6. Tighten the pivot lock handle (A, Figure 22).  
9.10 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  
(C, Figure 22) with a hex wrench, and slide the  
spindle sheave into the 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.  
Figure 20

Do not over tighten the bearing  
lock nut or the spindle bearings will overheat.  
4. The bearing lock nut should be tightened just  
enough to remove the end play and the  
spindle should still rotate very 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 loosened slightly.  
5. After the bearing lock nut (B, Figure 23) has  
been properly adjusted, carefully bend back  
into place any tabs on the tabbed lock washer  
(C, Figure 23).  
9.12 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.  
1. Disconnect Lathe from power source.  
2. Loosen the pivot lock handle (A, Figure 22)  
and lift up the tension handle (B, Figure 22) to  
raise the motor.  
Figure 22  
Belt shown in LOW speed range position  
3. Tighten the pivot lock handle (A, Figure 22) to  
hold the motor in the raised position. Slip the  
belt off the pulleys.  
9.11 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 23).  
4. Loosen the two set screws on the handwheel  
(A, Figure 23) with a hex wrench, and pull the  
handwheel off the headstock spindle.  
5. Loosen and remove the bearing lock nut (B,  
Figure 23) and tabbed lock washer (C, Figure  
23).  
1. Use a screwdriver to carefully bend back any  
tabs on the tabbed lock washer (C, Figure 23)  
that interfere with the insets on the bearing  
lock nut (B, Figure 23).  
6. Slide the spindle a little way out of the  
headstock, just enough to remove sheave or  
belt.  
NOTE: You may have to tap the end of the  
spindle with a wood block to move it. (Do NOT  
use a steel face hammer directly against the  
spindle.)  
7. If replacing the spindle sheave, loosen the two  
set screws (C, Figure 22), and slide the  
sheave off the spindle.  
8. Install the new spindle sheave, loosely  
securing the two set screws. Make sure the  
sheave is oriented properly.  
9. Slide the spindle back into place, install tabbed  
lock washer (C, Figure 23), and bearing lock  
nut (B, Figure 23). Check for any spindle play  
at this point (See “Checking Spindle Play”).  
Figure 23  
2. Place the end of a flat head screwdriver down  
against one of the insets of the bearing lock  
nut (B, Figure 23).  
10. Re-install the handwheel and tighten the set  
screws (A, Figure 23).  
11. Align the new sheave (see sect. 9.10, Sheave  
and Belt Alignment) then tighten the two set  
screws (C, Figure 23) securely on the sheave.  
3. Tap the handle of the screwdriver with a mallet  
so that it turns the bearing lock nut (B, Figure  
23) tighter in a clockwise direction. Rotate the  
bearing lock nut only about 1/16” at a time.  
15

12. Loosen the pivot lock handle and lower the  
motor using the tension handle. Re-tighten the  
pivot lock handle.  
If you suspect there is a problem with the inverter  
or the inverter settings, contact Powermatic  
technical service at 1-800-274-6848.  
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.  
10.0 Operating controls  
See Figure 24.  
(A) On/Off Button: Push in to stop the Lathe; pull  
out to start.  
NOTE: If there is a power outage while operating  
the Lathe, the Lathe will not automatically restart  
once power is restored. Cycle the on/off switch in  
order to restart the machine.  
11.0 Operation  
The information which follows is general in nature  
and is not intended to be a complete course in  
wood turning. Nothing can replace the knowledge  
gained by talking with experienced woodturners or  
consulting books, trade articles, and such like.  
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 adjustable  
levelers to help reduce vibration.  
2. Check bearings; adjust only if endplay exists.  
3. Check belt; it should be snug but not overly  
tight.  
Figure 24  
(B) Forward/Reverse  
4. Bed ways; keep clean, use steel wool to  
remove any rust spots, and apply paste wax to  
prevent buildup of rust and finishes.  
When turning with a face plate,  
make sure both set screws on the face plate are  
tight (see Figure 21) before reversing the  
spindle. Failure to comply may cause the face  
plate to spin loose from the spindle.  
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.  
(C) Speed Control Dial: Always start the Lathe at  
the lowest speed, with the dial rotated all the way  
counterclockwise.  
7. Tailstock; clean and lubricate ram and locking  
device.  
8. Lighting; proper lighting is essential to  
eliminate shadows and reduce eye strain.  
A.C. Inverter (mounted to rear of headstock)  
The PM2020 Lathe uses the latest technology in  
A.C. inverter drives to provide infinitely variable  
spindle speeds within the specified ranges (shown  
under sect. 5.0, Specifications). The inverter  
controls the speed of the motor by varying the  
frequency of the voltage supplied to the motor. The  
inverter provides an acceleration ramp that  
eliminates the shock of normal starting. Also, a  
braking feature eliminates long coasting periods  
after the Lathe is turned off.  
11.2 Turning tools  
If possible, select only fine 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 may be acquired. The  
following tools provide the basics for most  
woodturning projects (see Figure 25):  
The 2 horsepower motor is specially designed for  
use with inverter drives, and is balanced to reduce  
noise and minimize vibration.  
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  
The A.C. Inverter does not require any  
programming – it is 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.  
eliminate waste wood.  
Spindle Gouges – 1/4", 3/8", 1/2", used to turn  
beads, coves and other details.  
16  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Deep Fluted Bowl Gouge – 1/4", 3/8" and 1/2",  
used for turning bowls & plates.  
Never allow the tool to rest in one place on the  
wheel, keep it moving and use a light touch.  
Square Scraper (Bedan) – 3/8” or 1/2", used to  
create square shoulders.  
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.  
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.  
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 splitting the  
stock.  
Figure 26 shows the basic profile shapes in spindle  
turning.  
Figure 26  
11.3.1 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 remain.  
Put a dimple in the stock with an awl or nail, or  
use a spring-loaded automatic center punch.  
Figure 25: 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.  
2. Extremely hard woods may require kerfs cut  
into the ends of the stock (Figure 27) using a  
band saw, so the wood will accept the spur  
center and the live center.  
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.  
17

The tailstock ram is capable of  
exerting excessive pressure against the  
workpiece and the headstock. Apply only  
sufficient force with the tailstock to hold the  
workpiece securely in place. Excessive  
pressure can overheat center bearings and  
damage both workpiece and Lathe.  
10. Move tool support into position. It should be  
parallel to the workpiece, just below the  
centerline and approximately 1/8" to 1/4" from  
the corners of the workpiece to be turned, as  
in Figure 29. Tighten support base to Lathe  
bed.  
11. Rotate workpiece by hand to check for proper  
clearance.  
Figure 27  
12. Start lathe at lowest speed and bring it up to  
the appropriate RPM for the size of workpiece  
used. Consult digital readout on the  
headstock.  
3. Drive the spur center about 1/4” into the  
workpiece, using a wood mallet or dead blow  
hammer as shown in Figure 28. 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 the headstock is locked to the  
Lathe bed.  
5. Clean the tapered end of the spur center and  
the inside of the headstock spindle.  
6. Insert the tapered end of the spur center (with  
the attached workpiece) into the headstock  
spindle.  
7. Support the workpiece while bringing the  
tailstock into position about 1” away from the  
end of the workpiece. Lock the tailstock to the  
bed.  
Figure 29  
11.3.2 Cutting techniques  
Roughing out  
1. Begin with a large roughing gouge. Place the  
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 30. Make long sweeping cuts in a  
continuous motion to rough the piece down to  
a cylinder.  
Figure 28  
8. Advance the tailstock spindle 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 fly off, but do not use excessive  
pressure.  
9. Tighten the spindle locking handle.

Figure 30  
Figure 31  
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.  
"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 being  
rolled up at both sides.)  
5. Once the workpiece is roughed down to a  
cylinder, smooth it with a large skew. Keep the  
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).  
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 32.  
6. Add details to the workpiece with skew, parting  
tool, scraper or spindle gouge.  
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 and cut down  
each side to form the bead. Roll the tool in  
direction of cut.  
Figure 32  
Coves  
5. Repeat from the left side. The two cuts should  
meet at the bottom and leave a clean "V" cut.  
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 towards  
the bottom of the cove. See Figure 31. Stop at  
the bottom; attempting to go up the  
opposite side may cause the tool to catch.  
6. Additional cuts may be taken to add to either  
the depth or width of the cut.  
Parting Off  
1. Use parting tool.  
2. Move the tool over the desired width of the  
cove.  
2. Adjust lathe speed to lower RPM for parting  
through a workpiece.  
3. With the flute facing the opposite direction,  
repeat step 1 for other side of cove. Stop at  
bottom of cut.  
3. Place tool on tool support and raise the handle  
until it starts to cut and continue to cut toward  
the center of the workpiece.  
4. Loosely hold on to the piece in one hand as it  
separates from the waste wood.

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.  
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 the lathe and use a brush or paper towel to  
apply the finish. Remove excess finish before  
restarting lathe. Allow to dry and sand again with  
320 or 400 grit sandpaper. Apply second coat of  
finish and buff.  
11.4 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 move  
headstock to opposite end of bed - see Figure 9).  
Figure 33  
11.4.2 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 should 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.  
11.4.1 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.  
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.  
2. Always select the largest diameter face plate  
that can be used for the workpiece to be  
turned.  
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.  
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.)  
11.4.3 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.  
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 33. Both waste block and  
workpiece should have flat surfaces for gluing.  
11.4.4 Checks and cracks  
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.  
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.  
control, use your whole body to move the  
gouge through the workpiece.  
As you turn bowls from green wood, make sure  
7. As the bowl takes shape, work on the bottom  
(tailstock end) to accomodate attaching a face  
plate.  
you maintain  
a
consistent 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.  
8. Turn a short tenon (about 1/8" long) the size of  
the hole in the faceplate. See Figure 34. This  
will allow centering the workpiece when the  
faceplate is attached.  
11.4.5 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.  
11.4.6 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. 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.  
Figure 34  
9. (NOTE: If you plan to use a chuck, turn a  
tenon of the appropriate length and diameter  
to fit your chuck.)  
Large domed scrapers can also be used to help  
clean up the interior surfaces of bowls. A light  
touch with the scraper slightly tilted will eliminate  
some of the ridges occasionally left by an  
inexperienced bowl gouge.  
10. Stop the lathe, remove workpiece and attach  
face plate or chuck (see sect. 11.4.1, Mounting  
Stock).  
The surfaces of faceplate and  
workpiece should mount flush to each other.  
11.4.7 Bowl Turning Techniques  
To Shape Outside of Bowl:  
11. 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 later.  
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.  
To Shape Interior of Bowl:  
1. Stop the lathe and move tailstock away. (You  
may want to remove the center from the  
tailstock to avoid bumping it with your elbow.)  
2. Drive spur center into the top of the workpiece  
with a mallet or dead blow hammer.  
2. Adjust tool support in front of the bowl just  
below centerline, at a right angle to the lathe  
ways.  
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.  
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.  
4. Turn workpiece by hand to ensure proper  
clearance.  
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 35.  
5. Start lathe at lowest speed and bring it up to  
the maximum safe speed for the size of work  
to be turned (see sect. 15.0). 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  
21  
Download from Www.Somanuals.com. All Manuals Search And Download.  
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  
Figure 35  
Before doing maintenance on  
the Lathe, disconnect it from the electrical  
supply by pulling out the plug or switching off  
the main switch. Failure to comply may cause  
serious injury.  
6. Use the left hand to control cutting edge of  
gouge, while right hand swings tool handle  
around toward your body (Figure 35). 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.  
Maintenance on the PM2020 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.  
(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.)  
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 on the inverter.  
Do not disassemble inverter to clean!  
7. Develop wall thickness at the rim and maintain  
it as you work deeper into 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).  
Frequently clean out the morse tapers on both  
headstock and tailstock. Commercially available  
taper cleaners may be acquired from tool stores.  
8. Work the tight area around faceplate or chuck  
with 1/4" bowl gouge.  
9. Begin the separation with a parting tool, but do  
not cut all the way through yet.  
11.4.8 Sanding and finishing  
1. Remove the tool support and adjust lathe  
speed to approximately 500 RPM. High speed  
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 stand for several

13.0 Indexer positions  
How to use the chart  
The indexer is shown as viewed from the tailstock  
end of the Lathe. Points A, B, C and D are the  
holes in the head casting. The holes in the spindle  
collar may be considered as numbered 1 through  
12.  
Example: You wish to rout 9 flutes on your spindle  
blank. Locate the “9” in the “No. of Flutes” column;  
each flute angle will be 40°. The index pin should  
first be inserted into hole combination “A-1”. Make  
your first flute at this position. Back off the index  
pin and rotate the spindle until the index pin can be  
inserted into hole combination “A-5”; this will be  
followed by “A-9”. Succeeding flutes will be made  
with the index pin in the B position: “B-2”, “B-6” and  
so on.

18.0 Electrical: Remote On/Off Switch (optional accessory)  
NOTE: The Lathe can only operate when both the headstock and remote switches are in the “ON” position.  
To mount the remote switch to your Lathe, proceed as follows.  
1. Disconnect all electrical power to the Lathe.  
2. Remove the two screws from the control panel. Do NOT disconnect control panel from wiring harness.  
3. Run the remote switch’s wiring harness through the opening in the back of the headstock and out through  
the front of the headstock.  
4. Connect the remote switch’s wiring harness to the back of the Push/Pull switch (refer to the electrical  
schematic, sect. 17.0).  
5. Reinstall the control panel to the headstock. From the back of the headstock, lightly pull out any excess  
wire that may be inside the headstock.  
6. The magnetic back on the remote switch will allow the switch to be placed anywhere on the Lathe.  
7. Connect electrical power to the Lathe and resume operations.
