'''Whipping''' is the tying of several turns of [[twine]] around the end of a [[rope]] to prevent it from unravelling. It is not to be confused with [[Rope splicing|splicing]], which is a method of joining two ropes together, or joining one rope to itself, usually to form an eye or loop. | '''Whipping''' is the tying of several turns of [[twine]] around the end of a [[rope]] to prevent it from unravelling.

Whipping usually starts inside and works towards the end of the rope. The twine is first laid along the rope end in the form of an elongated double '''S''' that lies along the valley between one strand and the next. As the binding progesses a length of twine is left protruding at the inner end of the whipping. A [[loop]] is left protruding at the outer end of the rope. | Whipping usually starts inside and works towards the end of the rope.

When the turns are complete, the end of the twine is passed through the loop and the free end of twine at the start of the whipping is used to tug the free end of the twine securely below the turns. The inner tail is cut off by inserting a sharp [[knife]] through the whipping at about the third turn. The severed end of twine is then pulled out. The result is neatly whipped rope with no visible twine ends. | When the turns are complete, the end of the twine is passed through the loop and the free end of twine at the start of the whipping is used to tug the free end of the twine securely below the turns.

The ends of some man-made fibers such as [[Dacron]], [[Nylon]], [[polyethelene]], [[polyester]], or [[polypropylene]] may be melted by heat to prevent their ends from fraying. | The ends of some man-made fibers such as [[Dacron]], [[Nylon]], [[polyethelene]], [[polyester]], or [[polypropylene]] may be melted by heat to prevent their ends from fraying. Bind two or three turns of [[plastic]] [[tape]] tightly around the point where the end is to be cut. Slice through the rope in the center of the tape with an electrically heated knife, or cut with a normal knife and melt the ends in a [[flame]] so that all the fibers are fused together. However, melting the fibers is a relatively poor method of finishing a rope's end and the end of any rope, subject to heavy use, should be whipped as well. | ||

[[Aramid]] fiber such as | [[Aramid]] fiber such as Kevlar cannot be melted - the fibers merely char. Such rope must be finished with an appropriate whipping - ideally one completed with a needle such as a [[Sailmaker's Whipping]] although a [[West Country whipping]] also serves well. | ||

Another modern alternative is "liquid whipping". | Another modern alternative is "liquid whipping". This is a commercial, glue-like product that is used by dipping the end of the rope into the liquid. When it sets, the product is flexible but solid enough to keep the rope together. Liquid whipping can be used on both natural and synthetic fibers. | ||
