Woodturning jigs are shop-made accessories that hold a tool, a workpiece, or a template in a repeatable position. They make cuts more accurate, reduce fatigue, and help you reproduce the same angle or shape again and again. For many turners, the most useful jigs are also the easiest to build from scrap plywood and a handful of bolts.
This guide explains what woodturning jigs do, the most popular types you can build yourself, where to find plans, what materials and tools you need, and how to build and adjust a simple jig safely.
What Is a Woodturning Jig?
A jig is any fixture that controls position or movement. In woodturning, that usually means one of three things:
- A tool guide that holds a gouge, scraper, or chisel at a fixed angle.
- A workpiece support that steadies a long, thin, or hollow piece while it spins.
- A layout or template device that transfers a shape, depth, or spacing pattern onto the work.
Jigs do not replace turning skill. They remove variables so that your skill starts from a consistent point every time.
Why Build Your Own Jigs Instead of Buying Them
Commercial jigs exist and work well for many tasks. Building your own still has clear advantages:
- Lower cost. Most simple jigs use offcuts, common hardware, and a few fasteners.
- Better fit. A jig built for your specific lathe bed, tool post, and swing will sit more solidly than a universal design.
- Easy repairs. If a part wears out, you can remake it in minutes.
- Custom features. You can add stops, scales, or handles that match how you actually work.
- Learning value. Building a jig teaches you how your tools and lathe interact.
Common Types of DIY Woodturning Jig Plans
Sharpening Jigs
Sharpening is where jigs pay for themselves fastest. A typical setup has two parts: a flat platform that sets a consistent bevel angle, and a pivoting arm that swings the tool across the wheel or belt at a fixed distance. Because the angle depends on the distance from the pivot to the grinding surface, the jig must be sturdy and repeatable. Building one usually involves a plywood base, a metal or hardwood arm, and an adjustable tool holder.
Duplicating and Copying Jigs
These jigs let you copy a master profile onto new blanks. A template is mounted behind or above the work, and a follower pin rides along its edge while a cutter removes material. They are popular for turning matched sets such as table legs, tool handles, and repeated small parts. A simple version uses a plywood carriage that slides along the lathe bed, a fixed template, and an adjustable follower.
Steadies and Hollowing Supports
A steady supports a spinning piece from two or more sides to reduce vibration and flex. Most shop-built versions use a ring or frame with adjustable arms fitted with small rollers or bearings. They are especially helpful for thin-walled bowls, long spindles, and hollow forms where the wall thickness gets very small.
Gripping and Holding Jigs
Shop-made holding devices let you reverse a piece and work the base without marring finished surfaces. Common designs use sliding wooden or plastic jaws that expand inside a recess, or a padded ring that presses against a rim. These are built around the size of the work, so measure carefully before cutting.
Specialized Jigs
Other plans you will find include sphere-turning guides, threading fixtures, sanding arms, indexing plates, angle-setting gauges, tool-rest extensions, and segmenting sleds. Some are simple brackets; others are precise mechanisms with bearings and fine adjustment screws.
Where to Find Free Woodturning Jig Plans
Plans are widely available if you know where to look:
- Woodturning clubs. Local and online clubs often publish member-designed plans and dimensioned drawings.
- Public libraries. Woodturning and shop-fixture books usually include measured drawings you can copy.
- Magazine archives. Back issues of woodworking magazines regularly feature shop-built fixtures.
- Hobby forums. Members post photos, sketches, and material lists for jigs they have built.
- Video tutorials. Many include on-screen dimensions you can pause and record.
- Open plan libraries. Some woodworking communities share free drawing files and printable templates.
Before using any plan, note your own lathe specifications: the distance between centers, swing over the bed, spindle thread, bed gap, and tool post size. Plans made for a different lathe often need small adjustments.
Materials and Hardware You Will Need
- Sheet goods: plywood or medium-density fiberboard for flat, stable bases and carriages.
- Hardwood: for wear parts such as guides, handles, and jaws.
- Metal angle or channel: for arms that must stay rigid.
- Low-friction plastic: for slides and bearing surfaces.
- Bearings and rollers: for steadies and pivoting arms.
- Fasteners: bolts, threaded inserts, star knobs, and washers, including nylon washers for smooth adjustment.
- T-slot hardware: for adjustable stops and sliding fences.
- Adhesives: wood glue for joints and epoxy for metal-to-wood connections.
Tools for Building Jigs
- A table saw or track saw for accurate straight cuts.
- A bandsaw for curved brackets and arms.
- A drill press for square, repeatable holes.
- A router for slots and recesses.
- Sanders for flattening and easing edges.
- Calipers and a marking gauge for checking thickness and alignment.
- Clamps, plus a tap and die set if you plan to thread metal.
Step-by-Step: Building a Simple Sharpening Jig
- Measure your setup. Note the height of your grinding surface and the space available beside it.
- Cut a stable base. Use plywood wide enough that the jig cannot tip during use.
- Mount the pivot. Install a bolt, bushing, or bearing so the arm swings smoothly with no side play.
- Build the arm. Make it rigid. A metal bar or laminated hardwood works better than a single thin board.
- Add the tool holder. Create a cradle or clamp that holds the tool without letting it rotate.
- Install an adjustable stop. A slot with a knob lets you set the distance from the pivot to the wheel.
- Add an angle reference. Mark a scale or add a small adjustable platform to set the bevel angle.
- Test with a spare tool. Check that the bevel sits flat against the surface before sharpening anything valuable.
Tips for Accuracy and Safe Use
- Build jigs from stable materials that will not warp with humidity.
- Use lock nuts or knobs so settings cannot drift while the lathe is running.
- Round over edges and remove splinters before use.
- Keep jigs clear of rotating parts and never bypass a guard to make one fit.
- Clamp or bolt jigs down. A jig that shifts mid-cut is more dangerous than no jig at all.
- Wear eye protection and control dust when cutting and sanding jig parts.
- Recheck alignment after every change of tool or setup.
Testing and Adjusting Your Jig
Start with scrap material. Make a test cut or a test sharpening pass and inspect the result. If the angle or shape is off, adjust one variable at a time, then repeat. Once the jig produces the result you want three times in a row, mark the settings so you can return to them quickly. Keep a short note of the dimensions, angles, and hardware you used, so rebuilding or repairing the jig later is straightforward.
Common Mistakes to Avoid
- Using material that is too thin, causing the jig to flex under load.
- Leaving too much play in pivots and slides.
- Building a jig before measuring the lathe and confirming clearances.
- Adding so many adjustments that the jig becomes hard to set repeatably.
- Skipping test runs on scrap wood.
Conclusion
DIY woodturning jig plans give you a practical way to improve accuracy, repeatability, and safety without spending much. The most valuable jigs are usually simple: a sharpening guide, a steady, a copying carriage, or a holding fixture built from plywood and common hardware. Start with one jig that solves a problem you face often, measure your lathe carefully, build it from stable materials, and test it on scrap before using it on finished work.
Once your first jig works well, you will likely see other places where a small fixture can save time and improve results. Exploring guides on lathe setup, tool sharpening, and shop-made fixtures will help you keep building on that progress.
