Hand Powered Newspaper Briquet Maker[edit]

Project developed by ABStilwell & Molson
This OSAT has been designed but not yet tested - use at own risk.
This OSAT has been prototyped.

You can help Appropedia by contributing to the next step in this OSAT's status.


The need was expressed for a device in which could turn waste newspaper and other light paper products into small burnable briquettes. This helps to turn waste in to a usable fuel source, and also allows the paper to burn much longer and more efficiently than just burning the unprocessed paper.

  4. Tape measure

Skills and Knowledge Necessary to Make the OSAT[edit]

  • Basic Woodworking Skills

Technical Specifications and Assembly Instructions[edit]

The handles were made of 1x4 I had laying around and ripped it to the following dimensions. You need to cut 4 pieces at 1x.75x12 inches long. On one end drill a 3/8 inch hole centered 1 inch away from the end. For the ends of the handle one is 4.25 inches long and the second is 5.75 inches long, both are 1x1.5 inches. Using 8-1.25 inch flat top screws anchor the tops to the handle.

The handles can be made out of any type of wood or alternate material that is approximately 12 inches long and can have a hole drilled into it to fit over the rod. Same goes for the Steel rod, you can replace it with anything that will fit inside a 3/8 inch hole and handle the forces from the handles being pushed down.

The assembly pictures show much longer rods than you need for the setup, you only 6 inches in length per rod.

Print Time Estimate - 14 to 16 hours dependent on printer speed and infill settings. Assembly time is approximately 30 minutes.
