I make bushels and bushels of compost every year. Literally, about 12-15 bushels. But I don't waste much time or money, doing it. I'm not in a contest to see how fast I can make it. I usually need it in the spring, so waiting until spring is no problem. I give away a lot of plants, and they're always planted in pure compost. I also save a lot of money not buying soil.
I have 6 big 18 or 20 gallon tubs hidden in my shrubs. I steal people's bags of grass clippings from the curbside in the spring, hide them in my shrubs for the summer. Sometimes in the spring, I can find bags that have leaves left over from the fall. Toward fall, I steal bags of leaves, and fill my tubs with alternating layers.
I never turn compost. I use fairly narrow layers of both green and brown, and it makes itself perfectly over winter. The work of turning is very hard and unnecessary, unless you're trying to win some contest for speed.
Sand in the finished soil is perfectly fine. You usually want some sand in your soil. You actually should be adding small hand fulls of sand to your compost in order to help earthworms. They need to be able to eat some grit to keep their bodies functioning right. To increase earthworm's, it's also a great idea to tear up corrugated cardboard and throw some scraps in. The earthworms will increase dramatically if they get to eat corrugated cardboard.
No dog or cat poop can be added. Animals who eat meat have some pathogens that can be passed on to people in vegetables that are grown in the compost. Manure from fowl, sheep, and rabbits, is wonderful, but remember manure works as a green, even though it's colored brown. If I'm lucky enough to get horse manure, I store it an extra a year because it's really sharp.
I put no weed seeds in compost. I also avoid putting in plants that tend to carry a fungus or virus, like tomato plants at the end of the year.
Some people try to make composting into a scientific project. It certainly doesn't need to be, and it doesn't need to be hard work either.
