OK, I'll try to explain this without a diagram. First you need to go to
a lumber yard or home improvment stroe and get a roll of concrete
reinforcemet wire and a set of heavy duty bolt cutters. Now cut the
reinforcement wire into 6 foot lenghts leavinging the spikes of the
wire on one end, these will be used to wrap around the other end of the
six foot lengths to bend them into a cylinder. After you have made the
cages into a cylinder, you will use the bolt cutters at the bottem to
remove two rows of the horizontal wires thus providinging the stakes to
anchor into the ground. Supplemental two foot rebar can be used to
anchor the cages by driving into the ground and wiring the rebar to the
cages. HTH
