I made the worm composter from Ana's plan and built a cabinet out of old pallets. The stack of worm composters drawers slide in and out of the cabinet on a heavy duty drawer glide set.
I used cedar fence board. For 3 bucks a board, it was worth the work to rip them down and sand them.
The bottom drawer has a tray built out of old flashing and slopes towards a hose bib in order to collect the worm tea. I designed the drawer insert out of cardboard and cut it out of flashing, using a pop rivet gun to put it together, sealing the seams with flashing caulking. The drawer has a sheet of aluminum window screen under the top square of cedar.
