What Exactly is a Wood Lathe Duplicator?
A wood lathe duplicator is a mechanical attachment that mounts to your lathe. Its primary function is to guide your cutting tool along a pre-made template, allowing you to duplicate the shape of that template onto a new piece of wood. Think of it like a pantograph for your lathe. The template can be a physical object or a drawing, and the duplicator system ensures that the tool follows the exact profile, creating matching parts with remarkable accuracy. This is a game-changer for anyone needing to produce multiple identical turned items.
Modern duplicator systems often use a tracer arm that follows the template. This arm is linked to a mechanism that controls the movement of your tool rest or the cutting tool itself. As the tracer arm moves along the contours of your template, the linked mechanism moves the cutting tool in parallel, mirroring the template’s shape on your workpiece. This means less guesswork and more consistency, especially for beginners.

Step-by-Step: Building Your DIY Wood Lathe Duplicator (General Guide)
Since specific plans vary, this guide provides a generalized approach. Always defer to the specific instructions in your chosen PDF plan.
Step 1: Prepare Your Workspace and Tools
Ensure your workshop is clean and well-organized. Lay out all your materials and tools. Read through your chosen PDF plans thoroughly to understand the entire process before you begin cutting.
Step 2: Cut Out the Main Components
Using your saws, carefully cut all the wooden and metal parts according to the dimensions provided in your plans. Precision is important here, especially for the parts that slide or pivot.
Step 3: Drill Pilot Holes and Assemble the Base/Mounting System
Mark and drill all necessary pilot holes for fasteners. Assemble the parts that will attach to your lathe bed or tool rest. Ensure this section is robust and won’t flex during operation.
Step 4: Construct the Tracer Arm and Follower
Assemble the tracer arm. If it uses a sliding mechanism, ensure the parts move smoothly. Attach the follower (stylus or roller) to the end of the arm that will engage the template.
Step 5: Build the Tool Post Slide mechanism
This is often the most intricate part. Assemble the slides, pivots, or linkages that connect the tracer arm’s movement to the cutting tool holder. Test the movement for smoothness and accuracy. It should move freely but without excessive play.
Step 6: Mount the Cutting Tool Holder
Attach the holder for your woodturning gouge or chisel. Ensure it’s aligned correctly so that as the duplicator moves, your tool cuts accurately along the path dictated by the tracer arm.
Step 7: Assemble and Test Fit
Bring all the sub-assemblies together. Mount the entire duplicator onto your lathe. Check how it fits. Make any minor adjustments needed for clearance or alignment.
Step 8: Create Your First Template
Using scrap wood or a stiff material like MDF, create a physical template of the shape you want to duplicate. You can trace a desired object, draw it freehand, or use design software. Ensure the template is smooth with no sharp edges that could snag the tracer.
Step 9: Initial Setup and Test Cuts
Mount your template onto the template holder and a piece of scrap wood onto the lathe’s headstock. Position the tracer arm on the starting point of your template. Carefully align your cutting tool with the starting point of your workpiece. Make a very light test cut. Follow the tracer arm with the template. Observe how the cutting tool mirrors the template’s movement. Make adjustments as needed to ensure smooth, accurate tracking.
Safety First! Operating Your DIY Wood Lathe Duplicator
Safety is paramount when working with any woodworking tool, especially when adding new attachments. Always prioritize safety:
- Read Your Lathe Manual: Understand your lathe’s limitations and safety features.

Troubleshooting Common Duplicator Issues
Even with well-made plans, you might encounter a few hiccups. Here’s how to address some common problems:
Issue: Jerky or Unsmooth Movement
- Causes: Binding slides, debris in the mechanism, misaligned components, too much force applied to the tracer arm.
- Solutions: Clean and de-gunk all moving parts. Ensure all components are parallel and aligned correctly. Lubricate slides if recommended by your plan. Practice a lighter touch when guiding the tracer.
Issue: Inconsistent Duplication (Parts not matching perfectly)
- Causes: Play or looseness in the tracer mechanism, lack of rigidity in the tool holder, flexing of the duplicator structure, template not perfectly flat or smooth.
- Solutions: Tighten any loose connections. Reinforce any parts that seem weak or flexible. Ensure your template is perfectly accurate and has no nicks or bumps. Check for any “slop” in the linkage between the tracer and the tool.
Issue: Template or Workpiece Coming Loose
Causes: Insufficient clamping, vibration loosening fasteners.
Solutions: Double-check that all clamps are secure. Use thread-locking compound on critical bolts if appropriate. Ensure your template is a rigid material, not too thin or flimsy.
Issue: Cutting Tool Not Following Accurate Path
Causes: Misalignment between tracer arm pivot points and tool holder pivot points (if applicable), incorrect geometry in the linkage.
Solutions: This often requires careful re-calibration. Refer back to your specific plans and diagrams, ensuring all pivot points are correctly aligned and parallel to the lathe’s axis of rotation.
