The composter is finished. Next to it you can see my worm composter, which was my first attempt at composting kitchen waste. Someday i'll blog about it, too.

Build your own rotating composter
I've managed to build my own rotating composter for about $50.
I've always wanted one, but they cost about $300 commercially.
The idea is that a rotating barrel is easier to aerate by simply rotating the drum.
Aerobic microbes are much more efficient at composting,
so you get finished compost much faster this way.
I found the plans for one from the Rodale Institute. Rodale does great work in the area of sustainable agriculture.
The plans can be found here in pdf format.
If you're following the plans, I would recommend replacing the 28 wood screws, #10 x 1.5", with #10 x 2", cuz the shorter ones won't go through two pieces of 2 x 4.

Close up of the latch that I used.
I made the bearings out of square pieces of wood. The larger bearing will be bolted to the barrel, and the smaller bearing is glued to it. The small side goes against the frame, i think to limit friction and so that the bolts don't catch against the frame.
Glue the little bearing to the bigger bearing.
You can see the piece of rebar that will go through the barrel and hold it in place on the frame.
