I made this high-tensile wire unwinder from two disk opener blades, some square tubing, flat stock, bolts, and springs. It is lighter, sturdier, and less expensive than commercial units. Adjust the tension by tightening the center bolt locknut. To change spools, simply turn the tabs inward or loosen the four bolts slightly to slide them in or out for different size rolls.
