How to make your own Vermicomposter

or... build a worm bin

Materials

• One large tote bin with removable lid (I used Rubbermaid's 53L tote)
• One boot tray to fit under the tote
• 1/2" ID CPVC Pipe, length determined by the following: width of tote (where the pipe will be) + 3/4" to 1" (19 to 25mm), times two
• Four CPVC end caps to fit 1/2" ID CPVC pipe -see picture

Tools required:

• Drill
• Bits:
  • 5/8" spade bit
  • 1/4"
  • 1/8"
  • 3/32"
  • 1/16"
• Sandpaper (medium fine, doesn't really matter)
• measuring tape (optional)

How it's done

1. Drill 5/8" holes 2" from bottom on sides, 2 on each side, for the pipe to go through (see picture)
2. Cut pipe to about 3/4" longer than width of bin, from hole to hole
3. Drill 1/4" holes through pipe at regular intervals, alternating at 90° from one to next
4. Sand ends of pipe so it fits through the holes in the bin
5. Drill 1/8" holes in lid (about two dozen) and around 2" from top of bin (I did 5 on each side, 3 on each end) (see picture) for ventilation
6. Drill several 1/16" holes in bottom of bin for drainage (see picture)
7. Drill 3/32" holes in end caps (4 or 5) -easiest to drill from inside, angled outward (see picture)
8. Put pipes through 5/8" holes, put end caps on pipes (see picture), put bucket on tray.

Oh yeah, and get some red wigglers.
