COILING GIZMO SET/ECONOIt couldnt be simpler! Crank wire around the rod as shown and youve made a coil spring. Pull the spring off and insert a core wire. Now coil this spring around the larger rod in your kit to form a cylinder bead. Then try shaping it into a bi cone or sphere. Econo includes two different size crank rods and a U bracket; Deluxe has five different size rods and a U bracket with a built in table mount base. Both include instructions.
