On one of the rare occasion's that I have watched a gardening
programme, I had notice a compost bin made from pieces of
timber with the ends notched so the pieces fitted together, I
thought that seems to be a good idea so I tried to find one in
the garden centres.

I once made myself one like that. Too late I realised the fundamental
design flaw in the concept: The top stuff is always the newly added
stuff, and the good compost has to be taken from the bottom, and the
system has neither door not gate.
