There is nothing wrong with rope being worn out through use, but unfortunately most rope is lost, destroyed or damaged so much it has to be discarded long before it has reached the end of its expected life span. Following are some rules for caring for ropes: Do not walk on rope. This grinds grit and dirt into the rope, cutting the fibres. Do not drag rope along the ground. This is often more severe than walking on it, damaging the fibres with dirt and grit more rapidly. Do not coil or store wet rope. Rope requires complete drying before putting away. Natural fibre ropes will rot if left wet. Do not leave knots in rope. All knots weaken it, some more than others. Leaving knots in rope creates kinks, which permanently weakens the rope. Do not allow rope to chafe over rock. It should be obvious that allowing a rope to chafe on a rock will wear the rope, but some fools do it. Place sacking, canvas or similar protection between the rope and the rock. Parts of a Rope The end of a rope in use is called the RUNNING END. The other end not in use, or made fast to something, is the STANDING END. The part in between the RUNNING END and the STANDING END is the STANDING PART. In the STANDING PART can be formed a BIGHT or LOOP. Coiling a Rope As you begin to coil the rope, feel which way it wants to go and shake out any twists or kinks. Use your foot to hold the rope down while you coil it. On a dusty or dirty surface, you should form the coil in your hand. Continue coiling until only the length of one coil remains. Coil ropes clockwise with the lay of the rope. Coils should be at least 0.5 metre in diameter and wider for larger ropes. Secure with a strop for hanging. Hang the coils; do not leave them on the ground. Hanging will enable air to circulate round the rope. Hank coil rope over left-hand small coils, depending on size of rope. When near the end of coiling, take a turn around the hank, then half a hitch, pulling it tight. The hank should be compact, not floppy. Hank a Rope To secure the rope, make a loop by turning back the end of the first coil. Wrap the remaining end around the coil. Go over the loop, but leave its end free. Finish off after lashing 10 centimetres, leaving 2.5 centimetres of loop showing. Pass the remaining end of the rope through the loop and pull it tight. Pull the end of the rope that forms the loop. This will pull the loop under the lashing and secure it. Tying Knots With one end in each hand take left over right, and turn, then right over left and turn. Used to join two lengths of medium size dry rope of equal size. The reef knot is ideal for tying parcels, holding rolled braillings of a tent and for Reef Knot bandages because the knot is flat when tied. The sheet bend is used in place of a reef knot where greater safety from slipping is required or the ropes differ in size. The knot is not easily undone. It is often used to attach a rope to an eye splice or Sheetbend to the eye of a pulley rope. A clove hitch is used to connect a small line to a larger rope or spar at right angles or for a two way guy during erection of poles and to fasten a rope to a spar while under strain. Also starts a square lashing. The clove hitch can also be made by forming two loops and slipping over the spar. Clove Hitch The rabbit comes out of the hole around the tree and then back down his hole. The bowline is used to provide a loop in the end of a rope for a sling etc. Its main advantages are that it will not slip and can be easily loosened. Bowline Square Lashing A square lashing is used where the spars will try to slide over each other, regardless of the angle at which the spars cross Begin with a clove hitch underneath the spar to be supported. (a) Wrap the rope first over one spar, then under the other, pulling tight all the time. (b) On the second time round, go inside the previous turn of rope on top, but outside underneath the spars. (c) After three turns, apply two frapping turns, which pull on the rope turns already made, making them even tighter. (d) Finish off with a clove hitch. (e) One way of remembering it is: 'wrap thrice and frap twice'. Diagonal Lashing A diagonal lashing is used where the spars have to be pulled together or when they tend to spring apart from each other – for example the cross- brace of a framework Begin with a timber hitch to draw the spars together. Pull the knot at right angles and wrap the rope three times around the spars, keeping the rope tight all the time. Wrap three more turns, this time over the timber hitch. Apply two frapping turns to pull tight the rope turns. Finish off with a clove hitch. Sheer Lashings A sheer lashing is used for joining two spars together to make a longer length It is important to have a good overlap of spars which should be at least a quarter of the length, but better still is an overlap of one third. Start with a clove or timber hitch around both spars near the end of the overlap. Continue with eight to ten turns round both spars (or for about 10- 15cm). Finish with a clove hitch around the second spar. To tighten, insert small wedges inside the turns Adding a second lashing will strengthen the overlap, as then no movement is possible in any direction. .
