Bradshaw Cordmaker, countertwisting to ply the yarn into a cord
During controlled countertwist (CCT), the Bradshaw rotates in the opposite direction of the initial overtwist (IOT). During the first phase of CCT, the yarn will lengthen slightly, so it is important to pull back to maintain constant tension. This prevents "jump-overs", areas where the plies are not arranged perfectly. I tilt the drill slightly backward to lift the Bradshaw about 1/4" off the table, and pull back slightly on the block that is attached to the drill. All of the weight remains on the table.
As CCT continues, the cord starts to shorten, and the cord is almost finished. I let the cord shorten a little more, and cut the power to the drill. Once the head stops rotating, I release the tension on the cord completely and place the drill on its side to tape the cord ends. Remember to tape the ends before cutting them.
