I created an Album for the pictures of the hose holders I made: Click link below.
Each hose holder requires (2) 3-3/4" round pieces and (2) 2-1/4" round pieces. (1) 3/4" PVC Cap, (1) 3/16" x 1-1/2" Lock Ring Pin (4) 1/2" long wood screws and a cut to length piece of 3/4 PVC Pipe.
I attached the 2-1/4" piece to the 3-3/4" piece and used a holesaw to drill a 1-1/8" Hole through the center of both. I cut off the edges of one of the 3-3/4" pieces to fit into the slot where the outter locking rings are. I glued the cap on the piece of pipe and slid the end piece on. I compressed the hose on to the pipe and added the other end piece. Marked the hole for the pin and drilled it through. I cut off the pipe at 1/2" passed the hole. The pin is 1-1/2" long.
I used the plastic cutting boards from Walmart but any type of plywood would do the same thing. That's 45 ft of hose in that storage bay. I place my slinky holders on top of these when stored. These holders can be made using any type PVC Pipe. This was made mostly from scrap I had around the house.
If I was making them again I would make the smaller circle 2-1/2" for a snugger fit.
