Heading into year 3 with these bins

Built out of scrap 4x4s from the shed base and box store 2×6 studs, which were under $5 at the time. Ripped a bevel on each 2x to allow for ventilation while keeping material contained. The front and middle slats can all be removed as needed to turn the pile.

Mostly use a compost spreader to screen it while top dressing the lawn. For edible gardens, I'll sift it through the 1/4" hardware screen.
