put a 55 gallon drum on the wheels of an upsidedown wheelchair. It rolls so easy. Then I cut a 12" x 12" hole in the middle of the drum. I put hinges and a hasp on the piece I cut out to make a door for loading the leaves, kitchen scraps, etc. Next I drilled about 20 1/2" holes in the bottom and in the removable lid about 6" from the edge so the liquid won't leak out. I rotate it every day, sometimes twice a day. When it's ready to empty I just roll a wheelbarrow under the edge of the barrel, remove the lid and rake the compost in the wheelbarrow, put the lid back on, put the ring back on the lid, tighten it up and start all over again.
You may have inspired me. I have a 55 gallon barrel that I was going to use for a rain barrel, but then we found 275-gallon cubes that used to hold soda pop syrup. Bigger is much better. Did you pop-rivet the hinges onto barrel? What sort of latch to you use to keep it from flopping open?
Pop rivets would be fine. I used nuts and bolts. You might get a free old wheelchair from your Senior Citizens Center. Check out my Large Basket Gardens under Fruit and Vegetable Gardens for Only Grass and Leaves in Compost. I'll post pictures when the plants get some size. I used a standard hasp made for a padlock to hold the door closed.
