Making a splice on a single braid rope

Splicing single braid rope is an essential technique for sailors and modern rope enthusiasts. This type of splice is often used with Dyneema ropes or other low-stretch synthetic materials. Simple to learn, it offers excellent strength and preserves the mechanical characteristics of the rope. This article details all the steps necessary to make a clean and durable splice, while explaining the required tools and tips for optimal results.

Why make a single braid splice?

Unlike knots, which can reduce the strength of a rope by up to 50%, a well-made splice retains up to 90-95% of its original strength. A single braid splice is ideal for:

• Applications requiring high strength (running rigging, textile shrouds, mooring lines).
• Make fixed loops for reliable attachments.
• Provide a clean and compact aesthetic.

Necessary material

Before you begin, make sure you have the following tools:

• A splicing needle or long-eye needle suitable for the diameter of the rope.
• A pair of scissors or a sharp knife.
• Duct tape to hold the ends in place.
• A textile marker.
• One meter.
• A lighter to seal the cut fibers.

Anatomy of a single braid rope

A single braid rope is made of a single set of fibers braided in a spiral, without a separate core inside. This makes these ropes lighter and easier to splice. However, their structure requires special attention to maintain the integrity of the braid.

Steps to Make a Splice on a Single Braid

1. Prepare the rope

1. Measure the required length:
   • Allow a working length of approximately 100 times the diameter of the rope. For example, for a 10 mm rope, leave approximately 100 cm of length for the splice.
2. Secure the end with tape:
   • Wrap tape around the end to prevent the rope from fraying during the process.
3. Cut cleanly:
   • If necessary, cut the rope at an angle to make it easier to work with and seal the ends with a lighter.

2. Create the loop

1. Determine the size of the loop:
   • Bend the rope to form the desired loop. For example, a loop for a carabiner should be large enough for the accessory to pass through freely.
2. Mark the key points:
   • Using a marker, mark where the rope will be inserted to form the loop and where the folded end should enter the main body.

3. Insert the end into the main body

1. Open the braid:
   • Using a splicing needle or long-eyed needle, separate the fibers from the main body at the marked point.
2. Insert the end:
   • Pass the end of the rope through this opening. Pull gently until the loop takes the desired shape.

4. Bury the end

1. Prepare the end to be buried:
   • Reduce the diameter of the end slightly by removing a few fibers over 5 to 10 cm. This will make it easier to bury and avoid a visible bump.
2. Insert the end into the rope:
   • Using the splicing needle, insert the end into the main body to a length of 100 times the diameter of the rope.
3. Smooth the rope:
   • Work the rope between your hands to smooth the transition and distribute the fibers evenly.

5. Secure the splice

1. Perform a final smoothing:
   • Pull the loop and main body to adjust tensions. Roll the rope under your hands to even out the splice.
2. Check the solidity:
   • Test the loop by applying moderate tension. If the splice is done correctly, it should not slip.

Tips for a successful splice

• Use the right tool: A splicing needle that is the right size for the rope diameter is essential for accurate work.
• Work in the direction of the twist: Single braid rope has a braided structure that must be respected when burying.
• Take your time: A rushed splice may be less solid and aesthetically pleasing.
• Practice: If you are just starting out, try it on an old string first before working on a new one.

Simple braid splice variations

Besides the classic loop, other splice configurations can be made with single braid rope:

• Straight splice: Used to connect two ropes of the same diameter.
• Splice with ring or swivel: Allows an accessory to be inserted directly into the loop.
• Finished splice with overbinder: Adds an aesthetic finish and protects the splice from wear.

Common applications

Splicing on a single braid rope is useful in many maritime and sporting contexts:

• Running rigging: For halyards, sheets or runners.
• Climbing equipment: To create safety loops.
• Domestic use: For strong and discreet fixings.

Advantages of modern single braid ropes

Modern ropes such as Dyneema have exceptional properties:

• Low elongation: Ideal for applications requiring high precision.
• High resistance: Much higher than other materials for the same diameter.
• Lightness: Floating and easy to handle, even when wet.

Common Problems and Solutions

1. The loop slides under tension:

   • Check that the buried end is long enough (100 times the diameter).
   • Make sure the rope has been smoothed well after burial.

2. The braid is difficult to open:

   • Use a finer tool to spread the fibers, or loosen the rope slightly before beginning.

3. The rope twists during burial:

   • Work slowly and adjust tensions regularly to avoid twisting.

Conclusion

Splicing single braid rope is an essential technique for sailors and water sports enthusiasts. When done well, it offers a durable, strong and aesthetic solution to your fastening needs. With the right tools and a little practice, you will be able to master this technique and adapt it to a variety of applications. Don't be afraid to experiment and perfect your method to achieve professional results every time.
