To ensure that that fiber is in the same position every time in the protochimney, we wrap the end of the fiber in electrical tape (even amounts on all sides). Once wrapped the fiber should fit snugly in the chimney thereby reducing the movement of the fiber. Addressing the remaining problem, we are still working on a proper solution. | To ensure that that fiber is in the same position every time in the protochimney, we wrap the end of the fiber in electrical tape (even amounts on all sides).
