Voyaging Tip #21 :Shaft Packing

Measure propeller shaft packing by looping around the shaft then finish off the ring by cutting the ends to meet at a 45° angle vertical to the shaft. At least two rings will be needed with the cuts of each ring placed on opposite sides of the shaft. Remember to remove all the old packing from the stuffing box using needle nose pliers before inserting the new packing. Caution-do not spiral wind a single piece of packing around the shaft which will bind in the stuffing box and ultimately score the shaft.
