DIY Wooden Wind Spinner from Decking Boards

A wooden wind spinner is a striking way to add movement to the garden. This project uses leftover decking boards and simple cuts to create a spiral spinner that turns beautifully in the breeze. The design looks complex but is surprisingly easy to build.

I love projects that use scrap timber, and decking boards are perfect for outdoor decor. They are durable, weather-resistant, and already designed for outdoor conditions. With a few careful cuts and some spacing between the pieces, the wood naturally forms a twisting spiral that spins smoothly in the wind. This tutorial shows you how to turn merbau decking offcuts into a garden spinner that looks impressive hanging from a tree, pergola, or verandah.

How to Make a Wooden Wind Spinner

Materials

• Decking board timber (offcuts)
• 6 mm threaded rod or long bolt (approx. 75 cm)
• 6 mm nuts
• 6 mm washers
• Wire eye strap
• Hook for hanging
• Exterior wood stain or paint (optional)

Tools

• Saw (drop saw, table saw, or hand saw)
• Drill with a 6 mm drill bit
• Measuring tape
• Pencil
• Sandpaper or sander
• Spanner or wrench

Cutting the wood pieces

I started by cutting the decking boards into strips measuring 19 mm × 10 mm × 210 mm. I made them slightly longer than needed so I’d have enough material to work with, and planned to use the offcuts to make a smaller wooden wind spinner.

Cut one centre piece at 21 cm, then cut matching pairs for each size on either side, reducing each pair by 0.5 cm as you work outward. This means you will need two pieces at 20.5 cm, two at 20 cm, two at 19.5 cm, and continue in the same pattern, decreasing by 0.5 cm each time, until you reach the final pair at 8.5 cm. Both pieces on either side of the centre are identical in length, creating a balanced, symmetrical wind spinner.

These pieces will form the layers of the wind spinner, so try to keep the cuts consistent to help the spinner balance evenly when it rotates. I used merbau decking, and the natural grooves in the timber add a nice decorative detail, giving the finished spinner extra texture and visual interest as it spins.

Sanding the wood

I lightly sanded each piece on a benchtop sander to soften the sharp edges and smooth the timber. Removing the hard edges helps the pieces look more finished and also reduces the chance of splinters when handling or assembling the spinner. I found the benchtop sander to be a quick and easy way to sand the pieces evenly, but any sander will work just as well. A handheld sander or even sanding by hand will achieve the same smooth result; it may just take a little longer.

Mark the Centre

Measure the centre point on each timber piece and mark it with a pencil or marker.

Drill the holes

I used a drill press to drill the centre holes so they were perfectly straight and uniform. This also made the process much quicker since there were 31 pieces to dril. A drill press helps keep every hole aligned, which makes assembling the spinner easier and helps it spin smoothly.

However, you can drill the holes with a handheld drill. Just take a little care to mark the centre accurately and keep the drill as straight as possible.

Create the Spacing

Using spacers between the timber pieces allows air to flow through the spinner rather than pushing against a solid block of wood. Without spacers, the pieces sit tightly together and the wind struggles to move them, which makes the spinner heavy and less responsive. I would recommend cutting the rod to size once the wood and spacers have been added.

The washers create small gaps between each piece, reducing friction and allowing each layer to twist slightly. This spacing helps the wind catch the edges more easily, so the spinner turns smoothly and consistently even in a light breeze.

Assemble the Wind Spinner

I bought the threaded rod from my local hardware store because it was the only place I could find it in a longer length. Start by sliding a nut and washer onto the threaded rod to create a sturdy base.

Next, add the first timber piece, then place another washer on top before adding the next piece. Continue stacking the timber pieces in the same way, placing a washer between each one to act as a spacer.

Once all the timber pieces are threaded onto the rod, finish with a washer and a nut at the top. Tighten the nuts just enough to hold everything securely while still allowing the timber pieces to rotate slightly. This small amount of movement helps the wind spinner twist and catch the breeze. Cut away any excess threaded rod with a hacksaw.

Finish the Timber

You can leave the timber natural or apply an exterior wood stain, paint, or clear sealer. Outdoor finishes will help protect the timber and keep the spinner looking great in the garden. Allow the finish to dry completely before hanging. I stained the wood on the wind spinner I made with all the offcuts for a different look.

Twist the Spinner

Gently twist each timber piece slightly to create and enhance the spiral pattern. Because the pieces gradually decrease in length toward each end, the slight twisting helps emphasise the tapered spiral shape. Adjust each piece a little at a time until the spiral looks even.

The washers between the timber pieces create small gaps that allow the wind to pass through, helping the spinner rotate freely rather than resisting the airflow.

Hang the Spinner

Our hardware store had nothing suitable for hanging my windspinner so I improvised and used a wire eye strap that I screwed into the top and used a recycled keychain with a fishing swivel.

Add a Decorative feature

To add a decorative touch to the bottom of my wooden wind spinner, I used a large glass bead that I salvaged from an old chandelier. The weight of the glass bead is perfect because it helps stabilise the spinner, keeping it balanced and encouraging smooth, steady rotation in the wind. At the same time, the bead adds a bit of sparkle and visual interest, giving the spinner a charming, eye-catching finish that complements the natural timber.

Tip: I found the wooden wind spinner performs much better when it’s hung from a loop of fishing line rather than attached directly to a hook on the pergola. In the wind, both will spin, but once the breeze drops, the one fixed to a hook stops almost straight away. The fishing line version keeps spinning for longer because the line twists and slowly untwists, allowing the spinner to continue moving even after the wind has eased.

Beaded garden stakes are a vibrant and charming way to add colour and decorative flair to your garden planters.

Created from recycled pallet wood, this Shou Sugi Ban wall art features a colourful finish that beautifully contrasts with the rich, charred grain of the timber.
