I tried making a compost bin on the ground with old tin around it but critters were able to get into it (armadillos, etc.). A lady was selling an old compost tumbler for $50 so I bought it.
I think you could do something similar with an old propane tank.
How the hinges are on the door. (I know, needs wd40 on the rust).
Screens on sides & barrel. I think if you cut holes & then put screening over the holes, it would be the same.
