Designs for a Modular Compost System

This modular compost system was designed by MCR Will S. in 2006/2007. He used almost entirely reused materials to build this bin, and has gotten many years of use out of it!

Thanks for sharing the photos and design, Will.

Instructions for Assembly

Plans for Will's compost bin. Build your own and share your pics with us!

• A & B: Hook left side and left front gate together.
• C: Hook left gate to centre.
• D: Hook right gate to centre.
• E: Hook right gate to right side.
• F: Screw back top board #1 with one Robertson screw, to left side post, to right side post, and to centre post.
  Straighten so sides are vertical and add two more Robertson screws to each post.
  This leaves each post with three square screws.
• G: Screw back bottom board #6 with one Robertson screw to left side post, to right side post, and to centre post.
  Add two more Robertson screws to each post.
• H: Unhook gates. Now screw narrow front bottom board with one Robertson screw to bottom of left post, to right post, and to centre post.
• I, J, K, L: Screw #5, #4, #3, and #2 backboards with one Phillips screw to left, to right, and to centre post.
• M: Add two more screws to each post.
• N: Place lid on top, with wood rail down. Screw hinges on with small Phillips screws.
• O: Place one of short wood boards (the pads) under each of the six posts.
  Add or remove soil to stabilize the box under the posts.
• P: Rehook each of the gates.
• Q: Optional: Stain, paint, or preserve inside and outside. It will last longer and the bugs don't mind.
• Start composting.
