Build Your Own Spinnable Compost Bin
I have heard that compost bins which can be turned are said to produce compost faster.
I create layered compost piles behind bushes. I add layers of new material, then once a year harvest my compost for the beds. Recently I saw one of these plastic compost bins that is a round tube which can be spun around. The turning action is said to produce compost faster. I was thinking of buying it, but it was nearly $200, and I wondered if I really needed it. I would like to have some compost faster though.
During the half-time of the World Cup match between Germany and Spain, an idea for how I could build such a compost bin. I was able to put it together in about fifteen minutes. I have these old metal mattress frames sitting in my shed. I pulled off the wheels. I grabbed a metal tube that would fit over the foot which held the wheel. I took a round trash can that I had been using for storing a tarp to be my bin. I cut a hole in the base of the can and one in the lid. I siliconed the lid onto the can. I slipped the metal tube through the holes. The tube was slipped onto the two footers on the two metal frame side. I dug two holes for the frame sections to bury them. The last step was to buttress the frames with some bracing. In the middle of the can I cut a lid. This was cut on three sides, so I can lift it up to put in my compostable matter. The trash can spins on the axis of the tube.

You may have the parts lying around your own home. I could have used an old broom handle for the axis. The trash can did not need to be round. I coud have used boards instead of the old bed frames. I wanted to clear the bed frames out of my shed, so maybe that is why the idea popped into my head. I also have a number of tubes, metal and pvc. To make everything look like the parts belong together, I am going to paint it. I think that may be the only issue. It does look slapped together, and it was. It works, so why go for something fancier? This was done yesterday, so I cannot say how fast I will be getting compost. I tossed in newspaper, vegetable skins, coffee grounds, pruned leaves, and some compost. I plan to do this every day. I can give it a spin each time I walk by the bin, so we will see what happens.
