WARNING Do NOT flux wire rope terminals. CAUTION Immerse wires carefully so the flux solution does not enter the core of hemp-center-type wire rope. Immerse the grit-blasted wires in the solution to within 1 inch of the top of the seizing for 5 minutes. 5. Remove the wire rope from the solution, shake, and turn the broomed end upright at once. Then allow it to dry for 5 minutes. Any evidence of rust on the wires after the flux-dry period will necessitate refluxing. Preparing the Terminals Using a degreased length of seizing wire, suspend the terminal from the top of the ultrasonic degreaser so it is submerged in the solution. Allow 10 minutes for the decreasing operation. Inspect the terminal and repeat the procedure if necessary. Rinse the terminal in a bucket of clean GRISOLVE MT-N for 30 seconds, then let air-dry for 5 minutes. NOTE Replace the solution in the ultrasonic degreaser after 10 terminals have been cleaned/degreased. Replace the rinsing solution after 10 terminals have been rinsed or as soon as the solution becomes cloudy. Lay the terminal in the grit blast cabinet. Plug the cable entry hole with the rubber plug hanging from the cabinet. Secure the doors on the side. Grit blast the internal surfaces of the terminal from both ends. Rotate the terminal so that the entire internal surface is blasted. Remove the terminal, invert it, and shake it thoroughly to remove residual grit. WARNING To keep arresting gear crews constantly aware of the health hazards associated with the present terminal pouring procedures, safety warning placards, fabricated by ship’s forces, will be posted in clearly visible locations in the arresting gear terminal pouring rooms/area. (See fig. 3-53.) Preparing and Pouring Zinc NOTE Use only special high-grade zinc NAEC PN323822-2. No other is acceptable. WARNING Personnel engaged in preparing and/or pouring molten zinc must wear protective clothing, such as goggles and gloves. A protective screen must be provided around the pouring station. A melting pot and furnace are used to melt the zinc. Use a ladle that is thoroughly dry and free from rust, scale, slag, or any other foreign matter. The quantity of zinc prepared should be sufficient for pouring several terminals and should be ready prior to placing the terminals on the wire rope.
