It might help to know how big it is supposed to be, and what the requirements for it are...for example, does it need to be a specific width, or could be anywhere from 2" to 6" wide? does it need to have a specific diameter inside for the shaft, and outside for the cable/wire/whatever to roll onto? Is there some weight limit you have in mind? Do you have welding capability, or a shop in town that could weld steel or aluminum, if you could cut a tube and make the "washers" for the ends? and is there some other way to attach it to a shaft?
