Flow Through Worm Bin 2

In production since last week this TexasRedWorm Flow Through 2 has been a work in progress for several years.  I have been looking at examples of flow through bins homemade and commercially available for some time.  This latest design is the latest version predated by several prototypes.   This latest evolution has been a success thus far.   I ended up purchasing the metal racks from Costco for about $137.  Easy to assemble and very sturdy, these were a great buy at a good price.  I spent about $70 on hardware (nuts, bolts, screws, washers, 20′ of .25″ cable, and cable clamps).  Key to a long lasting box built around the metal rack, were cypress 2×6’s from TexasDozer.com cut from my dad’s saw mill.  Cypress will not rot and in it’s natural state (no chemicals used to preserve the wood)  and will not leach out anything harmful to the worms or castings.

photo 1Two mason tubs purchased at Lowe’s for around $13 each rest on the bottom rack just below the flow through bin to catch castings.  The bottom of the bin was lined with newspaper and worms and compost were added.  We will let the worms go to work for several weeks feeding compost as needed.  Over the next few weeks the newspaper will break down and the bin will be ready to harvest.  For the initial harvest, remove by hand the newspaper from under the screen.  Use the winch from one side to move the cutting bar across the bottom of the bin one time.

I have tried several models of flow through systems and continue to tinker to get the results I’m looking for.  The idea is for the finished castings to fall through the grate at the bottom of the bin and the worms to work towards the top of the bin.

Materials: square metal tubing, plywood, braided cable, 1.5″ self tapping metal screws, small I beam we found for the base bar to mount winches, and 2 winches (one we salvaged and another from Tractor Supply @$20) for pulling each direction.

We welded a bar to slide along the bottom of the bin to agitate the castings through the grate.  I have tried other versions without the cutting bar, and castings tend to get clumpy and stuck.  Stay tuned for the big reveal when we add worms and a few finishing touches.

DIY Worm Trough

28 Apr

I had been thinking of building a feed trough style worm bed for some time.  I found some plastic 55 gallon drums on Craigslist.  My dad had some pine 2X4s cut from his saw mill, and we were in business.  We began by cutting the 55 gallon plastic drums in half w/ a skill saw.

Materials: (2X4s, plastic 55 gallon drums, 3 inch wood screws, roofing screws, Thompson’s water seal)

Next we cut the 2X4s to border the open 1/2 end of the drum.  We used 3″ screws to piece the wood together, and galvanized roofing screws to secure the barrel to frame.  The height off the ground, we sized to about waist high for ease of use and for clearance underneath.
We had enough time and materials to build 3 bins.  When finished, I sprayed some wood preservative on the untreated pine, then I added compost and worms.  These bins are kept in a shaded area, and covered with plastic lids.  I set up a bin for each species we raise (Alabama Jumpers, Red Worms, European Nightcrawlers)
Thanks to my dad (pictured) for the pine, and skilled labor.
