Bicycle Shredder V2
In this how-to we’re giving you an overview about the construction of our bicycle shredder. One and a half years ago we made the first video about how to build a bicycle shredder. Since then, we made further adjustments and are now proud to present you the second version of the machine (with a much better documentation). —
Step 1 - Get ready!
In addition to the download-kit, the following steps will give you further information, why the shredder is built the way it is. Furthermore a short introduction video and an assembling video is in the making to get a better understanding about the construction. Stay tuned!
Step 2 - Cutting Mill
There are different ways to build the axle. We decided to spend a bit more money on standard parts to reduce costs as machining and post machining on the lathe. That’s why we use those span sockets. However, we are aware that these components are not available in every country in the world. Take a look on the possibilities and competencies around you, it is also possible to manufacture the axle in a different way.
Step 3 - Material Lock
Step 4 - Sieve and Collection Box
Step 5 - Friction Wheel
Step 6 - Steel Frame
Before welding everything make sure everything is drilled and milled into the steel tubes. Afterwards it's a bit tricky to get them to the right places!
Another advice: welding the m16 nuts; make sure the two nuts are in one alignment. That's important to clamp the rear-wheel right in place. We take a long steel bar (14mm in diameter).
Step 7 - Height Adjustment
For the turning knob we welded a small steel strip on a clamping ring. The rest of it are just ready-to-use standard parts.
Step 8 - Wheel Mount
For the turning knob we lasered a part out of a thick metal sheet and welded it on a nut. Instead of a lasered part you can realise the turning knob as well by some steel strips and an angle grinder.
Step 9 - Safety Add-ons
To ensure an easy and understandable handling, a good way is to use our color system.
- Green: Everybody can touch/use it.
- Orange: The team can touch/use it.
- Red: Keep your body away from it, it's f***ing dangerous!
In addition to the color system we use common warning signs and tips and tricks written on the machine.
Furthermore we build safety add-ons, such as the belt protection and the shaft protection.
If you have ideas how to make the machine safer and better, feel free to share it with us and the community!
