Composting is easy and fun. Kitchen scraps, leaves and lawn clippings are allowed to decompose naturally and they become a healthy, nutrient-rich and beneficial soil for the garden.
In this instructable, I will show how I made a spinning double drum composter to make soil for my garden.
Step 1: Making the Frame
I decided against documenting every step with building the frame, mainly because it's a simple enough design.
The frame consists of 3 pressure treated 4x4's and 1 pressure treated 1x4, all eight feet long. One 4x4 was cut exactly in half and the 1x4 was cut into quarters - they were to become the 2 beams and 4 stakes.
I drilled pilot holes through the posts and into the beam and held them together with galvanized lag bolts. Each of the corners where the beam meets the post got corner braces and the top got flat braces. The braces are meant for extra support, since the barrels may become heavy. The space between the top beam and bottom beam was 3 feet.
I used a 2 inch hole saw to cut holes into sides of the posts so they can hold the poles later on.
Then, I used some exterior screws to fasten the stakes to the bottom of the posts. The entire frame gets cemented into the ground later and the 4 stakes offer additional support to the frame.
At the bottom of the posts and stakes, I drilled some screws partially into the wood to hold them into the cement better.
