Build a bicycle powered shredder!
COLLECTION
SHREDDER
HDPE
In this How-to, you will learn how we constructed our bicycle powered plastic shredder, and how you can built your own! Not only does it give you a relatively cheap way to shred plastic at zero operating costs, but it also gives you freedom from the electrical grid, all while keeping you fit and healthy!
In step 1 you will find a detailed construction plan and all the files necessary.

Via this link: drive.google.com: drive.google.com/drive/folders/1m8Bq35N_N-nw5llw7T16WAWR9GLb5i_L?usp=sharing , you can find a very detailed construction plan and bill of materials, along with technical drawings, laser cutting files and more. This should be more than enough for you to build your own bicycle powered shredder :)
We could not use the supporting files tab, since our files exceeded the maximum file size amount.

Precious Plastics has very detailed plans on how to built a shredder box. On the Precious Plastics Bazar you can also buy one.

With this custom flywheel and axle, you can create forward momentum to shred the plastic. The flywheel will also provide a perfect base to connect the gears talked about in step 5. All the cutting files and the technical drawings can be found in the files in step 1.

Built the shredder stand, which will provide a raised platform for the shredded pieces to fall out, and for safety reasons. In the construction plan we explained how you could optimise this stand, since we encountered some problems with ours.
-
We tried to maxime the power output, through two ratio transmissions, which come to a total of 1:4.6. This will deliver 4.6 more power at the expense of lower rotational speed. A large gear is attached to shredder box and a large crankset is attached to the custom flywheel.

Now with the finished result, let's start shredding some plastic! and lose a few pounds along the way :)
