Dave - I actually read your article several times and started my worm bins pretty much per your instructions. Plus per more research online. I have an idea of what the worm castings and eggs look like and my husband is going to build some wooden screens to sift the bin materials using 1/4" and 1/8" screen to save the worms and eggs, but how long will it take to compost all that cardboard and paper? I use a juicer to liquify the food scraps, so the worms can process it faster. Does it take a few months? Or sooner or longer for them to produce about 8 gallons of castings? I think that is what I will have once they process about 1/3 a bin full.
