Sure - a bit of wood cut to fit and tied around will be completely fine. Should last a decade or so.
I might be tempted by a few more 2" diameter holes in the sides, if you live somewhere moist, or I think you'll get slime rather than compost.

This is what the 'compost' looks like. Where did it all go wrong?

Also I haven't put anything in for 3 months.

Too dry, maybe? I occasionally pour a bucket of water or piss into mine.

Yep, definitely needs more piss, and probably to be tamped down somewhat. It would probably tolerate some grass cuttings mixed in if you've started that yet.

I'd been building a lovely muck heap out in the field behind me (with permission). Had about 20 tonnes of sweet-smelling horse shit, piss and hay. Steaming nicely in the cold air, rotting hard.
Then some cunt dumped about 50 tonnes of stinky wood shavings and horse crap on it, ruining its pleasing shape and giving it a pungency I dislike intensely and it's no longer steaming.
I can't complain, really, but it saddens me. I was proud of that heap.

Have you not been putting kitchen (vegetable) waste in there? If you don't want to piss in a bucket it's a good way to keep the moisture levels up.

Needs more piss.

Open the flaps, stick your shovel in there and jiggle it around for a bit.

Then as is .gs traditional, open the rear flap and piss in there.
