I studied up what plans I could find about compost bins. The closest to what I wanted was a plan which is listed on my site here under "Browse Projects: Garden items: Compost Bin, click here for a look at that plan.

I made mine with 4 x 4 posts instead of 2 x 4's. Also, my top is corrugated plastic instead of wood. Just liked the idea better, could be wood, I wanted the plastic. I think it will hold up better and it's pretty light to lift up. I did not put the "hold up arms" that their plan had. I could even now but I don't need them. I only lift the top to remove boards or put boards back in for access and it's only for a couple seconds so I'm happy with how mine is. I could certainly put some on yours if that's what you want.

I wanted a 3 bin plan so mine has 3. Just too produce more end soil and not have to turn the stuff as much as I would with a 2 bin. With this three bin I just pile it in and let it stand for quite a while, then I move it to the next bin, let it stand quite a while and then again to the 3rd bin. People can and do get all scientific about the ingredients, how often to turn, etc. I don't. When it's "a long time later" I just till it into the soil. Good enough for me.
