Lockdowns presented unique challenges, but also sparked creativity. For parents seeking engaging and educational activities to keep children occupied and learning, the DIY self-assembly windmill project offers a perfect solution. This fun and educational craft combines simple engineering principles with the satisfaction of creating something tangible and beautiful. It’s a fantastic opportunity to introduce children to concepts like wind energy, mechanics, and sustainability, all within the familiar confines of home. Beyond the educational benefits, the process is incredibly rewarding, fostering a sense of accomplishment and encouraging problem-solving skills.
This project utilizes readily available materials, making it both accessible and cost-effective. No prior experience is needed, making it ideal for a range of ages and abilities, with adult supervision, of course! To get started on building your own miniature marvel of engineering, simply follow the step-by-step guide outlined below.
Preparation and Safety Guidelines
- 12mm plywood
- Yogurt pot (or compass)
- Pencil
- Bandsaw
- 45-degree angle tool
- Cardboard pieces
- 8mm Brad point bit
- 9mm drill bit
- 3mm plywood offcuts
- Small mallet (or substitute)
- Curtain pole (or dowel)
- Glue
- Wood for stick
- Adult supervision is required at all times. Sharp objects and potentially hazardous materials will be used.
- Ensure the windmill is assembled securely to prevent parts from detaching and causing injury. Test the stability before allowing children to operate it.
- Never operate the windmill near power lines or in strong winds that could cause it to break or fly away.
Step-by-Step Instructions
Prepare the Base
- Mark out a circle on a piece of 12mm plywood using a yogurt pot or compass. Determine the center.
- Draw a line through the center and use a 45-degree angle tool to mark positions for the blades.
- Mark the blade positions (1 cm each) and cut slots using a bandsaw set at a 45-degree angle. Use cardboard pieces as guides.
Prepare the Base Create the Spindle
- Create the central spindle using dowels by drilling a 9mm hole (pre-drill with an 8mm brad point bit).
Create the Spindle Make the Blades
- Cut the blades from 3mm plywood (250mm wide, 100mm for each vein). Shape and sand the veins to fit the spindle slots.
Make the Blades Prepare the Support Stick
- Cut and prepare a piece of wood for the windmill support stick.
Prepare the Support Stick Make the Assembly Tool
- Make a mallet from a piece of curtain pole and dowel (or use a substitute).
Make the Assembly Tool Assemble the Windmill
- Insert the blades into the slots on the disc using the mallet.
- Insert the spindle into the disc and attach it to the support stick. Add a washer for reinforcement.

Tips
- Using a compass for the initial circle is more accurate than a yogurt pot.
- Sanding the edges of the veins and blades will result in a smoother, safer final product.
- A substitute for the mallet can be made from easily accessible materials, like a clothes hanger.
- Adult supervision is recommended when using tools and hammering.
