Great idea! I save the spools that the electric wire comes on. When I am done with the fence, I put a long 1/2" carriage bolt through the empty spool center hole, tighten a nut down and then chuck it into my 2 speed cordless drill. I use the low (screw driving) speed and hold the drill so that the spool is pointed downwards. I use one hand to guide the wire on without kinking. It does get pretty heavy to hold by the time the spool gets close to full. I suppose a guy could rest it on the bed of a truck/UTV while he was reeling it in.
