Dh built me a make-shift "bin" out of three pallets (the front being open). As for turning it, watering it, putting things on in layers....
I turn it when I happen to think of it.
I water it when I happen to remember.
Layers? Nope. I just toss stuff on and hope for the best.
The very bottom of my pile is awesome - the other day, I dug out what looked like rich, brown earth, only it's compost. My pile could be better, and I could have two or three going, but what I do have, primitive as it is, works.
