3.0 Safety warnings  
For your own safety, read this instruction manual before operating the tool.  
Wear Eye Protection  
1. KEEP GUARDS IN PLACE and in working order.  
2. REMOVE ADJUSTING KEYS AND WRENCHES. Form the habit of checking to see that keys and  
adjusting wrenches are removed from the tool before turning it on.  
3. KEEP THE WORK AREA CLEAN. Cluttered areas and benches invite accidents.  
4. DO NOT USE IN A DANGEROUS ENVIRONMENT. Don’t use power tools in damp or wet locations, or  
expose them to rain. Keep work area well lighted.  
5. KEEP CHILDREN AWAY. All visitors should be kept at safe distance from the work area.  
6. MAKE THE WORKSHOP KID PROOF with padlocks, master switches, or by removing starter keys.  
7. DON’T FORCE THE TOOL. It will do the job better and safer at the rate for which it was designed.  
8. USE THE RIGHT TOOL. Don’t force a tool or attachment to do a job for which it was not designed.  
9. USE THE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. When using  
an extension cord, be sure to use one heavy enough to carry the current your product will draw. An  
undersized cord will cause a drop in the line voltage resulting in loss of power and overheating. The table  
below shows the correct size to use depending on the cord length and name plate ampere rating. If in  
doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

10. WEAR PROPER APPAREL. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other  
jewelry which may get caught in moving parts. Nonslip footwear is recommended. Wear protective hair  
covering to contain long hair.  
11. ALWAYS USE SAFETY GLASSES. Also use face or dust masks if the cutting operation is dusty.  
Everyday eyeglasses only have impact resistant lenses, they are NOT safety glasses.  
12. SECURE WORK. Use clamps or a vise to hold the work when its practical. It’s safer than using your hand  
and it frees both hands to operate the tool.  
13. DON’T OVERREACH. Keep proper footing and balance at all times.  
14. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and safest performance. Follow  
instructions for lubricating and changing accessories.  
15. DISCONNECT TOOLS before servicing; when changing accessories, such as blades, bits cutters, and the  
like.  
16. REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure the switch is in the off position before  
plugging in the machine.  
17. USE RECOMMENDED ACCESSORIES. Consult the owner’s manual for recommended accessories. The  
use of improper accessories may cause a risk of injury.

18. NEVER STAND ON A TOOL. Serious injury could occur if the tool is tipped or if the cutting tool is  
unintentionally contacted.  
19. CHECK DAMAGED PARTS. Before further use of the tool, 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.  
20. DIRECTION OF FEED. Feed work into a blade or cutter against the direction of rotation of the blade or  
cutter only.  
21. NEVER LEAVE THE TOOL RUNNING UNATTENDED. TURN THE POWER OFF. Don’t leave the tool  
until it comes to a complete stop.  
22. 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.  
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.

5.0 Electrical connections  
5.1 Grounding instructions  
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. This tool is equipped with an electric cord having an equipment-grounding  
conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and  
grounded in accordance with all local codes and ordinances.  
Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified  
electrician.  
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.  
Check with a qualified electrician or service personnel if the grounding instructions  
are not completely understood, or if in doubt as to whether the tool is properly grounded. Failure to  
comply may cause serious or fatal injury.  
Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the  
tool's plug.  
5.2 115 Volt operation  
As received from the factory, your planer/molder is ready to run at 115 volt operation. This planer/molder, when  
wired for 115 volt, is intended for use on a circuit that has an outlet and a plug that looks like the one illustrated  
in Figure 1a. A temporary adapter, which looks like the adapter as illustrated in Figure 1b, may be used to  
connect this plug to a two-pole receptacle, as shown in Figure 1b if a properly grounded outlet is not available.  
The temporary adapter should only be used until a properly grounded outlet can be installed by a qualified  
electrician. This adapter is not applicable in Canada. The green colored rigid ear, lug, or tab, extending from  
the adapter, must be connected to a permanent ground such as a properly grounded outlet box, as shown in  
Figure 1b.  
Figure 1a  
Figure 1b  
5.3 230 Volt operation  
If 230V, single phase operation is desired, the following instructions must be followed:  
1. Disconnect the machine from the power source.  
2. This planer/molder is supplied with four motor leads that are connected for 115V operation, as shown in  
Figure 2a. Reconnect these four motor leads for 230V operation, as shown in Figure 2b.  
3. The 115V attachment plug, supplied with the planer/molder, must be replaced with a UL/CSA listed plug  
suitable for 230V operation, similar to the one shown in Figure 3. Contact your local Authorized JET  
Service Center or qualified electrician for proper procedures to install the plug. The planer/molder must  
comply with all local and national codes after the 230 volt plug is installed.

10.1 Depth of cut  
Read and understand all  
assembly instructions before attempting  
assembly. Failure to comply may cause serious  
injury.  
Maximum depth of cut is 1/8”  
up to 5-1/2” wide, and 1/16” on stock over 5-  
1/2” wide. Trying to cut more in one pass will  
cause stress on machine and could damage  
cutterhead.  
9.2 Unpacking and cleanup  
Thickness planing refers to the sizing of lumber to  
a desired thickness while creating a level surface  
parallel to the opposite side of the board.  
1. Finish removing all contents from the shipping  
container. Do not discard any shipping  
material until the planer/molder is set up and  
running properly.  
The quality of thickness planing depends on the  
operator’s judgment about the depth of cut. Depth  
of cut depends upon the width, hardness,  
dampness, grain direction, and grain structure of  
the wood.  
2. Inspect contents for shipping damage. Report  
damage, if any, to your distributor.  
3. Compare contents of shipping carton with the  
contents list in this manual. Report shortages,  
if any, to your distributor.  
The maximum thickness of wood that can be  
removed in one pass is 1/8” on wood up to 5-  
1/2” wide and 1/16” on wood wider than 5-1/2”.  
4. Clean all rust protected surfaces with a mild  
solvent or kerosene. Do not use lacquer  
thinner, paint thinner, or gasoline; these will  
damage painted surfaces.  
When planing hard wood, take light cuts or plane  
wood in thin widths.  
Make a test cut when working with a new type of  
board or different kind of operation. Check the  
accuracy of the test cut before working on the  
finished product.  
5. To prevent rust, apply a light coating of paste  
wax to the table surface.  
9.3 Assembly  
10.2 Adjusting depth of cut scale  
1. Remove dust hood. Check gib screws on  
cutterhead for tightness. Reinstall dust hood.  
Note: Recheck after five minutes of operation.  
Recheck again after every 2 hours of use.  
Use caution when placing  
hands near cutterhead. Knives are extremely  
sharp. Failure to comply may cause serious  
injury.  
2. Attach the handle to the post with a hex socket  
cap screw.  
1. Take a test cut.

2. Measure the cut piece.  
10.5 Knife adjustment  
3. Adjust pointer accordingly.  
Any  
adjustment  
or  
replacement of knives must be done to all three  
knives at the same time. Failure to comply may  
result in an out-of-balance cutterhead which  
will lead to bearing failure.  
10.3 Feed rate adjustment  
The planer/molder has two speeds that feed the  
work piece, at 10 feet per minute (FPM) for  
improved surface finish when molding and 20 FPM  
for faster planing.  
Use caution when placing  
hands near the cutterhead. Knives are  
extremely sharp. Failure to comply may cause  
serious injury.  
To change the feed rate gears:  
1. Disconnect machine from power source  
(Unplug).  
1. Disconnect machine from power source  
(Unplug).  
2. Remove acorn nut holding the gear cover.  
3. Remove two hex socket cap screws and two  
washers.  
2. Remove screws securing dust hood and dust  
chute.  
4. Remove gears and position according to  
operation. See gear chart (Figure 7).  
3. Remove dust hood and dust chute.  
4. With a marking pen, label each knife on the

holding motor plate to stand.  
9. Raise or lower knife to correct height.  
10. Tighten knife bar locking screws. Note: Tighten  
each large lock bar independently. Take half  
turns alternating on each end until lock bar is  
tight against the knife. Tighten small lock bar  
after two large lock bars are tight. The small  
lock bar requires two spacers to firmly hold the  
knife. Tighten in the same manner as the large  
lock bars.  
4. Push down on motor to tension belt. Belt is  
tensioned properly when moderate finger  
pressure on belt midway between the two  
pulleys causes approximately 1/4” deflection.

Never stand directly in front of  
or behind machine while planing or molding.  
Always stand to one side. Failure to comply  
may cause serious injury from kickback.  
•
Turn the threaded bushing counter-  
clockwise to raise roller and clockwise to  
lower roller.  
Never attempt to plane a  
workpiece shorter than 14” or thinner than 1/2”.  
Failure to comply may cause serious injury.  
•
•
•
Raise or lower roller until it contacts the top  
of the block on both ends of the roller.  
Block should slide in and out with a  
minimum of force.  
Never plane more than 1/8” on  
stock narrower than 5-1/2” and 1/16” on stock  
5-1/2” and wider in one pass. This will cause  
stress on machine, lead to premature wear, and  
may damage knives and/or cutterhead.  
Tighten jam nuts and re-check.  
9. Repeat this process with outfeed roller. Retain  
the wooden blocks for future use.  
The use of a dust collection  
system is highly recommended. If a dust  
collection system is not used, remove hose  
adaptor from dust hood to prevent wood chips  
collecting in dust hood and backing up into  
machine.  
The JPM-13CS is supplied with planing blades  
mounted in the cutterhead. Planing can be done at  
10 FPM for an improved surface finish or 20 FPM  
for faster planing. Work pieces longer than 24”  
should be supported with infeed and outfeed  
rollers.  
Figure 12  
10.8 Adjusting chip deflectors for  
planing  
1. Adjust table height to produce desired depth of  
cut.  
Adjust the outfeed chip deflector (as shown in  
Figure 13) to within 1/4” to 1/8” of planing knives to  
prevent chips from being pressed into the planed  
surface of the work piece by the outfeed roller.  
Note: Adjusting the chip deflector too close to the  
cutterhead while planing will cause a higher than  
normal noise level especially when using a dust  
collector. The use of a dust collection system with  
the capacity to handle a large volume of material is  
highly recommended.  
2. Start machine.  
3. Stand to one side and grasp work piece in the  
center.  
4. Gently slide work piece into infeed side of  
planer/molder until infeed roller begins to  
advance the work piece.  
5. Let go of the work piece and allow the feed  
rollers to advance the work piece.  
6. Catch the work piece as it comes out the  
outfeed side of the planer/molder.  
11.1 Dealing with warped wood  
Warp is caused by different grain directions in a  
piece of wood drying at different rates during the  
drying process.  
Wood warped across the width - Cupped wood  
is planed flat on one side first, then planed flat on  
the other. Ripping the board down the middle will  
avoid huge amounts of waste in planing to  
thickness.  
Figure 13  
The infeed chip deflector (curved piece attached to  
the top cover with three screws and wing nuts)  
must be adjusted as close to the cutterhead as the  
13

Wood warped lengthwise - Feed rollers will  
flatten a lengthwise warped board as if it were flat,  
but the board will spring back to its original shape  
once out of the planer. A lengthwise warped board  
must be jointed flat on one side on a jointer before  
being thickness planed.  
3. Remove dust hood (B, Figure 14) and dust  
chute.  
4. Loosen three wing nuts (C, Figure 14) and  
slide the curved infeed chip deflector (D,  
Figure 14) out of the way.  
5. Tighten screws to hold chip deflector in place.  
It is not used in the molding operation.  
Twisted wood - Twisted lumber or lumber twisted  
lengthwise is difficult to thickness plane. The wood  
may be so twisted that it cannot be thickness  
planed. One possible solution may be to saw the  
board into smaller sections and see if the sections  
can be thickness planed.  
6. Remove plastic outfeed chip deflector  
completely.  
7. With a marking pen, label each knife slot on  
the cutterhead one, two, and three for easy  
identification.  
11.2 Wood Grain  
For 2” and under cutters:  
For an improved surface finish with minimal  
tearout, always plane the work piece with the grain.  
•
Loosen set screws on 2” lock bar at cutter  
number one.  
The work piece should be fed into the  
planer/molder so that blades are traveling with the  
grain as they finish the cut. The grain should be  
angled up toward the rear of the work piece as it is  
fed into the planer/molder.  
•
With the brass bar and a mallet carefully tap  
on lock bar outside of set screws to loosen  
taper fit of the lock bar.  
•
•
Remove spacers.  
Remove lock bar. Note: With 2” wide and  
under molding cutters, the planing knives  
remain in place (Figure 15).  
12.0 Molding setup and  
adjustments  
Set feed gear box to 10 FPM. (See illustration and  
•
Install lock bar but do not tighten at this time.  
Note: Depending on cutter width, 1” and under  
cutters will require a spacer next to the cutter.  
instruction in section 10.3).  
12.1 Installing molding cutters  
Cutterhead knives are sharp.  
Use extreme caution when working in close  
proximity. Never attempt to mold without a dust  
chute and dust collection system. Failure to  
comply may cause serious injury.  
1. Disconnect machine from power source  
(Unplug).  
2. Remove screws (A, Figure 14) securing the  
dust hood.  
Figure 15  
•
Install cutter in place of spacers. Cutters must  
face proper direction and be seated fully in the  
cutterhead.  
For cutters over 2”:  
•
Loosen set screws on all lock bars at cutter  
number one.  
•
With the brass bar and a mallet, carefully tap  
on lock bar outside of set screws to loosen  
lock bar taper fit.  
•
Carefully remove spacers, planing knives and  
lock bars.

When using cutters larger than 2” wide, the feed  
rollers will have to be set 5/16” below the cutter  
head. To set the feed rollers for molding:  
•
•
Install special lock bar that is included with the  
knife set. Make sure set screws are loose to  
allow locking adjustment. Do not tighten at this  
time.  
1. Following the method for setting the feed  
rollers when planing (previously explained in  
this manual), make another wooden block  
5/16” lower than the cutterhead block. See  
Figure 17.  
Install cutter. Make sure it is facing proper  
direction and is fully seated in the cutterhead.  
8. Install molding cutter gauge with hex socket  
cap screw and tighten to hold in place. The  
guide may be attached to either side. See  
Figure 16.  
Figure 17  
Figure 16  
2. Adjust the infeed and outfeed rollers in the  
same manner as setting the rollers for planing  
using this new block.  
9. Adjust the guide end to meet the cutter edge.  
10. Tighten the hex socket cap screw holding the  
guide bar and be careful not to move it during  
the alignment process.  
3. Label this block “feed roller molding”.  
4. Save the block for future use.  
11. Tighten lock bar set screws to hold cutter in  
place. Tighten set screws half turn each side  
to uniformly raise the lock bar until tight.  
Never lower infeed and  
outfeed rollers beyond 5/16” lower than  
cutterhead. This will cause severe stress on  
gear box and roller system.  
12. Rotate cutterhead to the second cutter insert.  
13. Repeat steps for cutter inserts two and three  
making sure the cutters are properly  
positioned according to the alignment guide.  
When using molding knives wider than 2”, the first  
pass or cut will remove approximately two thirds of  
the stock. Test cuts on scrap material will  
determine the number of passes required to  
complete the cut. Never attempt to complete a  
cut with less than two passes on smaller knives  
(under 2”) and three passes on larger knives  
(over 2”). Generally, the more passes, the better  
the finish.  
14. Remove guide.  
15. Check that all set screws in the cutterhead are  
tight.  
16. Replace dust hood and dust chute.  
17. Run machine for five minutes. Re-tighten gib  
screws in cutterhead. Recheck after every 2  
hours of use.  
Due to the variety of cutters available, it is  
impossible to cover every possible set-up. It is very  
important to use test cuts on scrap material before  
attempting cuts on project material.  
Never run the machine with  
the dust hood loose or removed. All cutter lock  
bar screws must be firmly seated before  
turning on the machine. Failure to comply may  
cause blade and/or cutter ejection resulting in  
damage to machine, cutter, and may pose  
hazard to operator.  
This machine is designed and intended for use with  
three matched knives in sets. Many companies  
offer knife sets that included only one knife and two  
counter-weights. These cause severe vibration and  
can damage the machine.  
12.2 Setting feed rollers for molding  
The infeed and outfeed rollers will have to be  
lowered for most molding operations. The amount  
of adjustment required will vary depending on the  
size and style of the cutter.

12.3 Making & installing a bedboard  
You must use a board over the  
planer/molder table when molding. This  
prevents the knives from hitting the table and  
allows the knives to cut into the guide boards  
to clean up the sides of the molding.  
1. Disconnect machine from power source  
(unplug).  
Figure 19  
2. Cut a piece of 3/4” particle board 12-7/8” wide  
and 31-1/4” long. Note: Board is 12” longer  
than the table to allow overhang (6” front and  
rear). This increases the work surfaces for  
longer pieces of wood stock.  
12.5 Guide rail placement and  
attachment  
1. Disconnect machine from power source  
(unplug).  
3. Mark and drill four 1/4” holes on the bedboard  
that match the pre-drilled holes in the  
planer/molder table.  
2. To assist in proper placement of guide rails, it  
is suggested to remove the dust hood and dust  
chute to clearly see the cutter knife and rail  
placement. It is also helpful to draw parallel  
lines on the bedboard to assure proper  
alignment of the guide rails from the infeed  
side to the outfeed side.  
4. Countersink the four drilled holes on the top  
side to allow installation of countersunk  
screws.  
5. Secure the bedboard to the table with four  
3/16” x 1-1/2” flat head machine screws, four  
3/16” x 3/4” washers and four 3/16” hex nuts.  
3. Molding cutter must be installed properly in the  
cutterhead. See “Installing Molding Cutters”.  
12.4 Making guide rails  
4. Lower table.  
Guide rails are used during the molding process to  
align the workpiece with the molding cutters. Using  
properly adjusted guide rails assures the workpiece  
passes the molding cutters in the same position  
using multiple passes.  
5. Carefully turn cutterhead so that one cutter is  
at the lowest point of the cutting arc.  
6. Slide in first guide rail and position inside edge  
of guide rail to outside edge of the finished  
work piece. Note: On many patterns this will  
be the outside edge of the knife.  
Guide rails should be the same length as the table  
(31-1/4”) and 2” wide and be made from smooth,  
straight hardwood, such as oak, maple, alder, etc.  
so they will not damage the cutters when they  
contact them. Some molding profiles require the  
knives to cut into the guide rails to clean up the  
outer edge to complete the cut. (Fig. 18)  
7. Clamp the guide rail to the bedboard using “C”  
clamps on both ends. (This can also be done  
by nailing with small gauge finish nails. Keep  
in mind the guide rails must be positioned  
properly before nailing. Be careful with nail  
length; do not nail through the bedboard and  
into the table). (Fig. 20)  
Figure 18  
Guides should be cut 1/4” lower than the maximum  
thickness of the final workpiece profile. Regardless  
of how thick your guide rails are, they must be  
notched to clear the infeed/outfeed rollers and anti-  
kickback fingers. See Figure 19 for pattern.  
Figure 20  
16  
Download from Www.Somanuals.com. All Manuals Search And Download.  
8. Position second guide rail on the table.  
Placement of this rail depends on the width of  
the board and if the board requires outer edge  
clean-up. Review molding procedure section  
for pre-sizing stock guidelines. When using  
knives that require outer edge clean-up, the  
workpiece will contact the guide rails only  
while wood is feeding into the cutterhead. After  
the workpiece passes the cutterhead, the  
outfeed roller will hold the workpiece in  
position.  
9. Clamp or nail second guide rail.  
10. Replace dust hood, dust chute and fasten in  
place.  
Figure 22  
Other considerations before molding to consider  
are wood hardness, moisture content, degree of  
warp, and direction of grain.  
11. Connect to the dust collection system.  
12. Make sure all adjusting tools and wood stock  
are removed from the machine.  
Never attempt to mold a  
workpiece shorter than 14” or thinner than 1/2".  
Failure to comply may cause damage to  
machine and/or serious injury to operator.  
TIP: Save money, time, and frustration by  
experimenting first with scrap work pieces before  
attempting to mold with expensive stock.  
13.0 Molding procedure  
13.1 Setting table height for first  
pass  
1. Do not connect machine to power source until  
instructed to do so.  
Never mold without using a  
dust collector. Molding without a dust collector  
may cause clogging of and damage to machine.  
2. Lower table to allow insertion of workpiece.  
Molding with professional results takes planning  
prior to starting. Always take a light cut for the  
smoother finish. Pre-sizing wood before molding is  
a necessity. Always pre-size the workpiece to 1/16”  
of the final thickness before running the workpiece  
through the molder.  
3. While looking into the front opening of the  
machine, raise the table until the workpiece  
just contacts the infeed roller.  
4. Record the height of the table as indicated on  
the scale to either side of the table.  
With profiles that require outer edge clean-up, the  
workpiece should be 1/8” larger than the final width  
allowing 1/16” on either side of the cutter. (Fig. 21)  
5. Lower the table and remove the workpiece.  
6. Raise the table back up to the recorded  
measurement.  
7. Raise the table one full turn above the  
recorded measurement to allow adequate feed  
roller pressure. This measurement is now the  
starting point for this particular job.  
8. Connect the machine to the power source,  
start the dust collector, and start the machine.  
9. Insert the work piece until the infeed roller  
begins to advance the workpiece.  
Figure 21  
10. Let go of the work piece and move to one side  
of the machine.  
With profiles that only cut the edge of the  
workpiece, the workpiece should be the same size  
as the final width. (Fig. 22)  
11. Retrieve the work piece from the outfeed side  
of the machine. Note: It is our experience that  
on the first pass using some cutters, the  
material may feed in a jerky motion. If this  
occurs, raise the table during the cut until the  
workpiece begins to advance smoothly. This  
point now becomes your first pass  
measurement.  
17

12. Run all stock to be molded through the  
machine at this time. Note: If you are  
molding several boards with the same  
profile and have to make several passes to  
complete the profile, you must run all  
boards through at each setting. This  
assures all stock will match the desired  
shape. This is especially important when  
splicing molded boards together such as  
crown molding or baseboards.  
13.2 Back Relief Molding  
Back relief molding is used to create a better fit  
over irregular surfaces. With less wood contact, the  
molding matches irregular surfaces more easily.  
The back relief cut is formed on the work piece  
first; then the workpiece is molded to its finished  
shape. (Fig. 23)  
Figure 24  
14.0 Maintenance  
Disconnect machine from power source  
(unplug).  
•
Keep anti-kickback pawls clean and operating  
smoothly to prevent injury due to kickback.  
•
Lubricate table with furniture wax or  
automotive paste wax for smoother feeding of  
workpiece. Do not use a lubricant that will  
affect the workpiece’s ability to accept stains  
or protective finishes.  
•
Replace feed rollers, blades, and cutter knives  
if they become damaged. Sharpen blades and  
cutters when they become dull.  
14.1 Lubrication  
Disconnect machine from power source  
(unplug).  
•
•
•
Coat the elevating screws with light automotive  
bearing grease once a month.  
Figure 23  
13.3 Tongue and Groove Molding  
Lightly coat the chain drive and gears with light  
automotive grease once a month.  
Tongue and groove molding is accomplished in the  
same manner as other types of molding. Keep in  
mind the edge guide must be taller to adequately  
support the work piece. The edge guides must be  
set 3/4” below the lowest point the cutter will travel.  
Lubricate four columns with 10W machine tool  
oil once a month.  
Cutting the groove first allows adequate support  
when cutting the tongue (Figure 24).
