Was Brian Duff, refering to, ss "Oxygen Starvation", that can happen when ss is prevented from exposure to air ?
Could not, water, by , capillary action work it's way down the 1 X 19 strands inside under the taping on the backstay wire , like it can and does on a swaged terminal barrel ?
The field design and fabricating advice , that I have read, says , never "pot" a ss structural fitting , or design a ss structural fitting that , can not be visually inspected, all around ?
Often times I see a "drip loop" , incorporated, when installing wiring on or around masts and ss rigging, especially at the mast head and at the partners,,,,, would not a drip loop be good to use where the GTO-15 attaches to the backstay, just above the insulator ?
