Joanna,
I like to build stuff. After a lot of reading, the CFT idea seemed like the practical thing to do. This is new to me so I don't have any results yet, but the idea is that the castings end up on the bottom and the worms stay above, where the food source is. While a few end up being harvested with the casting, the majority do no, so no need to pick through the piles to separate them. I posted pictures (on the previous page) of my set-up. The lower bin is the collection point when the castings are removed from the bottom of the upper bin. I'm guessing it will be a while before I get any results.
