The center portion is a trash can that is attached to two four foot diamter circles of plywood that were cut from a 4 X8 foot piece of plywood.
This above photo shows the moving portion supported by a piece of PVC.
The PVC is held by a wooden structure.
There are 150 feet of hose on the reel. This is composed of 15 spray nozzles that are 10 feet apart.
The hose reel is much too big for the 150 feet of hose. Its diameter can be reduced to 2.5 feet.
