Yes, there are plenty of compost bins on Instructables, but I wasn't satisfied with the looks of them and had specific lumber to use up from building a deck. These compost bins measure 3' by 3' by 2' tall. The front stiles are removable by sliding them up, making it easy to fork or shovel the compost out of the bins. The back stiles are screwed in place for stability. Other openings are screened with fiber glass mesh. Tops are hinged, each swings away from the center.
I built two bins so I can keep finished compost in one while the other is still working.
