To keep your garden rolling in fresh compost all-year round, try knocking together a basic dual-compartment compost bin out of salvaged wooden pallets or planking (avoid treated wood). Fill one section with fresh vegetable waste, while you let your compost ripen in the other. By the time you've tapped out your stash of matured compost, the pile in the adjacent bin should have cooked through, at least in part. Now, the nearly empty section holds the new vegetable cuttings. Keep up this game of switcheroo make separating your compost from the decomposing material a cinch.
If you have enough room in your yard, you can easily extend this concept into a three-bin setup. Start off by building your pile in your first bin. When this bin overfloweth, "turn the pile" by transferring it to the next bin with a garden fork (or similar tool), aerating the pile and spurring on decomposition at the same time. You should have fully matured compost hitting the bottom of your third compartment the next time you turn the piles, with the rest of your compost in early and middle levels of decomposition in the first two.
Instructables has a step-by-step guide to building a rudimentary two-bin setup. For an enclosed system, refer to Lowes' free how-to.
