Tutorial: Constructing a Bicycle-Powered Plastic Shredder

This guide outlines the construction of a bicycle-powered plastic shredder and provides instructions for building your own. The device offers a cost-effective method of shredding plastic without relying on electricity.

Step 1: Find detailed construction plans and necessary files.

    Open the construction manual

    Via this link: drive.google.com, you can access a detailed construction plan, bill of materials, technical drawings, and laser cutting files required to build a bicycle-powered shredder.

    Note: The files exceed the maximum allowed size for the supporting files tab.

    Built the custom axle

    This custom flywheel and axle generate momentum for shredding. It also serves as a base for connecting the gears discussed in step 5. Cutting files and technical drawings are available in the files in step 1.

    Shredder stand and container

    Construct the shredder stand to provide an elevated platform for the shredded pieces to exit and to ensure safety. Our construction plan outlines potential optimizations based on issues we encountered.

    Attaching everything together

    The power output is amplified through two ratio transmissions totaling 1:4.6, resulting in 4.6 times more power at a reduced rotational speed. A large gear connects to the shredder box, and a substantial crankset is attached to the custom flywheel.
