The provided reference demonstrates one technique: insert an old cable through the housing before cutting to help maintain its shape and prevent crushing.
Here's a more detailed look at how to cut cable tubing effectively:
Steps:
-
Preparation: Insert an old cable into the cable housing you wish to cut. This provides internal support. Ensure the old cable extends past the point where you intend to make the cut.
-
Cutting:
- Use cable cutters designed for this purpose. These cutters have sharp blades that create a clean, perpendicular cut without crushing or deforming the housing. A dull blade or improper tool can flatten the cable, making it difficult to thread the inner cable.
- Position the cable housing properly in the cutter. Make sure the blade will cut straight across.
- Apply firm, even pressure. Avoid twisting or bending the cable housing during the cut.
-
Finishing:
- Inspect the cut end. Look for any burrs or sharp edges.
- Use a small awl or pointed tool to open up the cut end. This ensures that the inner cable can pass through freely. Gently ream out the inside of the cut end to remove any plastic shavings or debris.
- Install a cable end cap. This protects the cable from dirt and moisture and provides a clean, finished look.
Tips for a Clean Cut:
- Sharp Tools are Essential: Invest in a good quality cable cutter. A dull cutter will crush the housing and make it difficult to thread the cable.
- Support the Housing: As demonstrated, supporting the inside of the housing (with an old cable or similar) helps prevent crushing.
- Smooth Edges: Remove any burrs or sharp edges after the cut to ensure smooth cable operation.
- Use Cable End Caps: Always install cable end caps to prevent fraying and contamination.
Why is Proper Cutting Important?
- Smooth Cable Action: A clean, perpendicular cut ensures that the inner cable moves smoothly within the housing.
- Prevents Fraying: Proper cutting and the use of end caps prevent the cable housing from fraying or unraveling, which can impair performance and lead to premature wear.
- Professional Finish: A clean cut and finished end provide a professional and aesthetically pleasing result.
