Hope you have success with your wormcity wormery.

I tried one of the original wormeries and had a few problems -the worms either escaped or died. Not being one to be deterred I decided to make my own.

It's made of wood supported on engineering bricks over a sand base, has wire mesh to keep out non-invited guests and is long enough that I can move feeding from one end to the other to allow for removal of compost - takes a few months to ween them across. This has been successfully in use for some 18 months now with none of the earlier issues.
