Always wear safety goggles or safety glasses and a full-face shield when needed. Use a dust mask in dusty workingconditions. Wear hearing protection during extended periods of operation.2. Tie back long hair, do not wear gloves, loose clothing, jewelry or any dangling objects that may catch in rotating partsor accessories.3. Check the owner/operator’s manual for proper speed recommendations. Use slower speeds for larger diameter or roughpieces, and increased speed for smaller diameters and pieces that are “true” or cylindrical. If the lathe is shaking orvibrating, lower the speed. If the work piece vibrates, always stop the machine to check the reason.4. Check that all clamping devises, such as on the tailstock and cutter holder are tight.5. Rotate your work piece by hand to make sure it clears the template holder and bed before turning the lathe “on”. Besure that the work piece turns freely and is firmly mounted. Make adjustments with the lathe turned “off “.6. Use only defect-free stock, without cracks, splits, checks or knots which could chip and fly out, causing serious injury.7. Hold the cutter holder firmly on the tool rest.8. Always move the cutter to the side before sanding or polishing.9. Perform periodic maintenance on your lathe and duplicator. Keep cutter sharp. Check for damaged parts, alignment,binding of moving parts, and other conditions that may affect its operation.10. Don’t use your lathe in damp or wet locations. Do not use in presence of flammable liquids or gases. Keep your workarea well lit.11. Remove chuck keys and adjusting wrenches prior to turning. Form a habit of checking for these before switching onthe lathe. Never leave the lathe running unattended. Turn power off. Don’t leave the lathe until it comes to a completestop.Specifications:Max Spindle LengthCML-DUP, CML-DUPJ , CMLDUPU 9”CML-DUPMAX12”

Mount duplicating attachment on your lathe as indicated in diagram 2.2. Move tail stock assembly to the right.3. The duplicator must be parallel to the lathe. To accomplish this: With the cutter point and the spur drive point just touching, tighten the template guide pin in placeresting against the front of the template holder.4. Slide the cutting assembly to the right, and with the template guide pin still resting against the front of the template holder,move the duplicator board forward or backto bring the point of the cutter into position so it is just touching the live center point of the tailstock. Tighten duplicator mounting bolts.5.The height of the cutter tool tip needs to be on the exact center line of the lathe spindle. This is accomplished by adjusting the plastic tool rest of the template holder upor down. Loosen the screws on the back side and adjust the level of the cutter tip even with the spur drive on the headstock andDiagram 2- SetupTailstockDiagram 2 - Setup (ML-DUP,CMLDUPJ,CML-DUPMAX)NOTE: Board configurationmay varyLathe Mounting and Setup Instructions: CML-DUPUThis setup mounts the universal duplicator to any lathe. For alignment, you must supply spacer blocks, a suitable lower mounting base and appropriatehardware. Locate the point of the cutter to rest at a height exactly even with the center line of your lathe’s spindle by mounting the lathe on a largeenough base to support both the lathe and the duplicator. Fabricate a set of riser blocks or a single platform to raise the cutter to a height equal to theHeight of the spindle center line.Use 1/4” lag bolts with a wood screw end or a 1/4” x 20 machine screw with a “T” handle, knob, or hex bolt head on the end. In the riser block below,glue in a threaded insert to secure the bolt.Diagram 2A - Setup for CUL-DUPU

For layer pieces, cut the piece in half lengthwise and MAXmp (or glue) to the follower forsupport.Diagram 3- Copying an Original Work pieceClamp original to follower supportFollower SupportOriginal Work pieceUsing PSI Template Sets for Projects that Mount on a Mandrel (pen kits etc)Preliminary Preparation1. Select the kit you intend to make and remove the brass tubes. Mount the kit’s bushings and tubes onto the mandrel without wood (see Diagram 4 below)2. Loosen the screws on the top of the template holder. Insert the steel template under the holder bar, press the template forward into the holder as far as possible. Handtighten down the bar to hold the template so that it slides left to right and front to back (under enough pressure not to fall out).Diagram 4- Setup Using a Pen Mandrel ProjectThe PSI template profiles are designed to use the kit bushings as the primary setup indicator. The following steps discuss how to align the cutter to a bushing and thenposition and secure the follower pin and template to ensure a precise setup. Note that this setup has to be done only one time (for a particular project).
PSI Woodworking ProductsLathe Duplicator User’s ManualSetting the Cutter Depth Alignment3. Secure the bushings and tube(s) on the pen mandrel. Secure the tailstock to the mandrel and tighten the locking nut.4. Position the point of the cutter exactly to the inside edges of the left hand bushing (if the bushings are step bushings, position the cutter exactly to the inside edges ofthe left-most part of the wood blank will rest.) Refer to Diagram 4.5. Loosen the follower pin wing bolt. The follower will slide freely front to back in its holder. Slide the template along the holder until the bushing area of the template isin front of the follower’s point. (Do not tighten the template in its holder yet.) Slide the follower forward until it barely touches the template (somewhere in the bushingarea of the template.) You can now lock the follower pin in place. Note: you can use a plier to tighten the follower’s wing screw (but don’t over tighten it to avoid strippingthe bolt.)Determining the Template Left to Right Alignment6. With the cutter still positioned at the right outside edge of the left bushing, slide the template to the left until the left side of the cutting profile touches the point tip ofthe follower pin. Refer to Diagram 4. (Note: some template profiles have straight edges and will not allow the point to match the left-hand template edges when the cutteris positioned up against the bushing. In this case back off the follower before sliding the template into position.)7. With the follower and template now in position, you can now lock the template in place by tightening down the locking screws. Slide the cutter to the right hand bushing and check the depth of the follower point. You may have to adjust the template in the holder front to back to match the proper depth on both right and left bushings(this may be necessary if the duplicator was not setup to be perfectly aligned to the lathe.)Finishing the Setup8. When preparing your kit’s wood blanks for turning a) Make sure that the blanks are exactly the same length as the brass tubes since all templates are designed to exactly match these tube lengths. b) Cut your wood blanks thick enough to make sure the template profile does not extend beyond the outer surface of the blank. (You cantest your wood blank by following the procedure listed under 10b.) Note:PSI kits, bushings and templates have been designed to match every time. If the tubes or bushingdo not match then it is possible that another vendor supplied your kit or bushings. Contact PSI for bushings and kits that are guaranteed to match the template profile.9. With the left hand bushing fixed in its setup position, assemble your blanks and bushings onto the mandrel (matching the template directions). To ensure proper setupcheck these items:a) With the cutter pressed against any bushing, the follower point should barely touch the template. If not, adjust the duplicator or template mounting asnecessary.b) Check that your wood is thick enough to match the widest diameter of the template’s profile (see the Diagram 5 below). To do this, press the cutter point tothe flat of your wood blank and slide the cutter left to right across the surface. Do this for each of the four surfaces. The follower must clear the template across all of theflats. If the follower hits the template, your wood is too narrow but all is not lost. You may be able to turn a thinner profile to match the minimum diameter of the blank.
PSI Woodworking ProductsLathe Duplicator User’s ManualTo match the minimum diameter, push the cutter towards the point on the flat that results in largest gap between the flat and the cutter point (because the follower pinwill be hitting the template). Loosen the follower pin, press the cutter forward until it hits the wood flat, back off the follower pin so that it hits the template while the cutter is still touching the wood. Tighten the follower. Follow step 10 b below to check whether or not your profile is too narrow.Adjusting the Thickness of the Turned Profile10.You can easily turn a thinner or thicker profile by adjusting the follower pin depth.a) For a thinner profile (or this if your blank is not quite thick enough) you can back off the follower pin from the template. Note that the difference in yourworkpiece’s finished diameter will be double the distance that you’ve backed off. You can check to make sure your profile is not too narrow as followsb) With the profile diameter thinner there is now a chance that your cut may be too deep and hit the brass tube. Check this by mounting up a set of brass tubesonto the bushings (without wood mounted on). Run the follower pin across the template profile and watch the cutter tip. If the tip hits the tube at any point then theprofile diameter is too thin and you will have to change to a set of thicker blanks or adjust the depth accordingly.Cutting with the Duplicator (Diagram 6)1. Pull tool holder back before turning the machine on. Never allow cutter to contact spur drive or chucks.2. Place hands comfortably on each side of cutter assembly, with fingers guiding the cutter side to side and forward and back always keeping the tool holder down againstthe plastic tool rest.3. With the lathe on start at one end, slide cutter to the other end, removing a small amount of material with each pass. Cutting may be done in either direction.4. When the guide pin comes into contact with the template or original turning, it will start to follow the contour as you cut.5. Continue cutting, leaving the deepest cuts until last for increased stability. If the deepest cuts are made too soon, the work piece may flex and break.6. Move the cutter from side to side as you progress into deep cuts to provide clearance for the cutter bit and to prevent binding.7. After completing the cutting, make a final pass to clean up the surface.8. If there are flat areas on your completed turning, it means the cutter needs to be adjusted to cut deeper. Do this by moving the guide pin back a tiny but (1/64” or less)and turning the work piece again.9. When your turning is complete, rest the cutter assembly off to one side, out of the way of the work piece and moving lathe parts.10. Sand and finish your work piece on the lathe if desired.Diagram 6- Cutting TechniqueDiagram 7- Depth Stop BoltUsing the depthstop boltUse the depth stop to micro-control your cut depth. The system also guarantees a straight cut. Turn the wing nut (J) towards the knob on the depth bolt(G) to advance the follower in small increments. The end of the bolt will stop the cutting depth independent of the follower and template. As you cut, the depth stopinitially will create straight cuts as the wing nut is backed off. The follower pin will hit the template and cause the cutter to follow the template pattern.

Use a spur center or a Lathe Chuck to grab the project wood at the headstock end. The wood will bepressed into the live center point at the tailstock end.Measure the total length of the finished project (between the shoulders of the template). Cut your wood about 2 1/4” longer than the finished product.Mark the center of each end of the blank. Drill a 1/8” pilot hole into each end. For projects #TPL13 and #TPL15- drill the holes deep enough (about 1”)so that the finished turning will have pilot holes necessary for drilling or mounting hardware.Position the template into the template holder so that the “center extension” (narrow part of the template) is slid towards the live center on the tailstock.For templates TPL14, TPL100, TPL101, and TPL102, make sure the rounded end of the project is positioned towards the tailstock end. Adjust the cutterand follower as indicated in Diagram 8. Mount the wood after positioning the cutter and followers.When cutting, leave the deepest cuts for last since the final cuts may separate the project.Follower alignswith templatecenter extension(narrow part oftemplate)Special Instructions for TPL103- Candle Holder Base (Diagram 9)Instead of drilling 1/8” pilot hole at the headstock end, Drill a hole 3/4” or 7/8” at the tailstock end of your work piece, depending on the size of thecandle you intend to use.You will need to mount the blank with a “jam chuck” to secure and turn the blank using the headstock. Turn a dowel the diameter of the hole. Insertsthe jam chuck and secure the work piece as shown below. Proceed with turning per the instructions above. (Diagram 8)
PSI Woodworking ProductsLathe Duplicator User’s ManualGeneral Information: Hints and Tips about Using Your Duplicator1. The cutter bit is High Speed Steel and has a point on both ends and should extend about 5/16”. Loosenset screw to remove or reverse cutter.2. To maintain sharpness, never allow the cutter to come into contact with the spur drive or chucks whilethe lathe is on.3. Cutters may be re sharpened by hand on a fine, flat stone, such as an Arkansas or India (medium. orhard). All three surfaces should be honed on the stone, bringing the cutter bit to a sharp point.4. With proper care of the cutter, you should be able to produce several hundred small turnings before resharpening is needed.5. It is recommended that you wipe the steel rods of the cutter assembly with some light oil or WD-40 fromtime to time. Moisture from your hands could cause some rust on the rods. Always wipe on some oil beforelong term storage.6. Your work piece should not be any longer than you actually need. Excessive length increases the possibility of spindle whip.7. When turning long, thin spindles, it may be necessary to use your fingers to provide support for thework piece to reduce flexing during cutting.8. In the beginning, start with turnings about 1 4”-3/8” square until you get a feel for the correct amountof pressure to be used for cutting. Usually the harder woods are more rigid and stable and easier to work,producing a nicer finished product.9. With practice, you can free-hand your shapes and then use the original for a template. The originalshould be of hard wood and polished with wax to provide a smooth surface for the guide pin.10. To make dowels, adjust the guide pin in or out to slide along the template holder (without a template)to create a dowel the desired diameter.
