Large wheelie bin wormery (Shirley CR0)

I repurposed a spare wheelie bin a few years ago for us as a wormery. It has worked well for making compost and has a huge capacity, but some design flaws - the tap is very easily blocked (so I added extra holes for drainage out the sides) and it's difficult to extract the compost through that small porthole.

Still, as photos show, it works well! And is very fox and rat-proof.

The porthole window screws in and out.

I'll be emptying it this week. Does anyone want to try my DIY solution?

Collect from near Millers Pond in Shirley. It's heavy (about as heavy as a wheelie bin with some extra pieces inside)
