With energy prices constantly rising, many homeowners are looking for ways to cut their electricity bills. One great option is to build your own small scale wind turbine from recycled and scrap parts. Constructing a DIY turbine is an affordable and fulfilling project that allows you to generate clean, renewable energy and reduce your reliance on the grid.

In this comprehensive guide, I will walk you through the entire process of building a scrap parts wind turbine from start to finish. I’ll cover selecting optimal materials, critical design considerations, turbine assembly, installation, and maintenance. Follow along to learn how I built my own functional turbine on a budget using mostly salvaged components.

Selecting Materials from Scrap Parts

The first step is sourcing secondhand or salvaged materials to build the turbine. With some creativity and hunting around at scrapyards and garage sales, you can find most of what you’ll need either very cheaply or for free. Here are the key components I used for my scrap parts turbine:

Rotor Blades






Design Considerations

Carefully planning out your wind turbine design is crucial to maximizing power generation. Keep these key factors in mind:

Blade Number & Length

Generator Output

Tower Height

Turbine Direction

Assembling the Turbine

Once you’ve collected materials and planned the design, it’s time to start building. Follow these steps to assemble your scrap parts turbine:

1. Cut rotor blades to equal size

2. Attach blades to hub

3. Add generator mount

4. Build tail structure

5. Test spin

Your scrap parts wind turbine is ready for installation!

Installing the Turbine

Proper installation is key to maximizing power generation once your turbine is built:

1. Erect tower

2. Mount turbine near top

3. Wire to battery bank

4. Ground the system

Proper grounding is extremely important for safety and preventing damage to electronics.

Performing Regular Maintenance

Like any mechanical system, your DIY turbine will require periodic maintenance to keep it running efficiently:

Performing preventative maintenance will extend the turbine lifetime and productivity.


Building a small wind turbine from scrap parts is a great DIY project that allows you to generate your own renewable energy. Follow the steps I outlined for selecting used materials, designing efficiently, constructing the components, installing professionally, and maintaining regularly. With some persistence and ingenuity, you can build an effective scrap parts turbine that will slash your electricity bills for years to come. The ability to harness clean wind power is incredibly rewarding.
