DIY cracked log lamp: preparation
This rustic design is great in the garden and makes an eye-catching home accessory. The cracked wood log lamp DIY project takes approximately one day.
DIY cracked log lamp: What wood should I use?
- Coniferous wood is ideal for this DIY log lamp because it’s soft and easy to carve.
- Choose an older log that already has some cracks.
- The log you choose should be straight, without any branches or forks.
- Remove the bark before you begin your project.
Wood cracks naturally as it dries. These unique natural features create interesting patterns in your DIY wooden lamp, which you can exaggerate with your chainsaw. If your log doesn’t have any dry cracks, cut some light slits with your chainsaw after removing the log's core.
Protective equipment: designed to keep you safe
Always wear personal protective equipment when working with your chainsaw. This includes cut protection trousers, safety boots, safety glasses, a face shield, work gloves and a helmet if there is a risk of falling objects. You don't need to wear ear defenders with most cordless chainsaws, but you should check the operating manual for your product to find out if ear protection is recommended. Fully familiarise yourself with the tool before you use your chainsaw for the first time, and check it's in flawless condition before each use. On request, your STIHL dealer will be happy to prepare your tool for its first use, and will also advise you on models and sizes of protective clothing that you can try at your leisure. Please remember that personal protective equipment is no substitute for safe working techniques.

STIHL cordless chainsaws feature narrow chains and guide bars, making them ideal for this project. Cordless power tools are particularly quiet and emission-free during use. Use low-kickback saw chains, included as standard with the chainsaws that we recommend here.
DIY cracked log lamp: step-by-step instructions
With the preparation complete, it’s time to start making your DIY wooden log lamp.
- Fix the log to a sturdy sawhorse using a chain or tensioning belt.
- Draw a square on the end face of the log. The wood inside the square will be removed, so leave enough wood around the edges to make sure that your DIY wooden lampshade will be stable.
- Mark a point on the chainsaw guide bar with your pencil, at approximately 25 cm, so you can plunge cut to the same depth every time.
- As you cut each side of the square, angle the tip of the guide bar into the log at approximately 45° to remove a pyramid-shaped piece of wood.
- Take care not to damage the outer edges of the wood as you work.
- Remove your DIY cracked wooden lamp from the sawhorse.
- Measure the deepest point of the hollow space inside the log using your ruler.
- Add 3 to 5 cm to this length and mark it on the outside of the log.
- Cut your cracked log lamp to size using the chainsaw.
- Hold the saw straight and cut straight across the wood.
- Fix the lamp to the sawhorse with a chain or tensioning belt.
- Use the chainsaw to carefully deepen and widen the dry cracks, cutting through to the middle of the wooden lamp.
- Saw the cracks down to the tensioning belt. You can also add new cuts: a total of four to six cuts for the light to shine through are ideal, depending on the thickness of the tree trunk and your personal taste.
- You could add mitre cuts around the top of the lamp to round off the edges.
- Use an angle grinder to smooth the edges of the wood and the light slits. Using high-quality sandpaper is an alternative.
- Your lamp does not need treating if it is for outdoor use.
- Treat your lamp with hard wax oil if it is for indoor use.
- Place fairy lights inside the lamp to light it up. Use weather-resistant and water-resistant fairy lights for outdoors.
- Use a plug safety box to protect the plug socket for the power supply against the elements.
Making the lamp stable: To make your DIY wooden log lamp more stable, saw a small channel into the base for the cable to run through. This makes it safer and lets your lamp can stand up straight.
