Take the bucket and cut it in half long ways from the top to the bottom. Over lap the edges about half an inch or so and then screw it together and set it on the ground. We cut the bottoms out also. Pour in your concrete and put in your stakes. After it sets up just take out the screws and pull the bucket off and around the concrete. This works very well. Me and a buddy have made tons of them like this and we made some tonite that way. Now we just got to wait until it sets up to remove the buckets.
This does work.
