Old school technique uses "Whipping" or "Whip tie" knots on leather bar wrap installations, finished with a waterproof gloss
How to Finish Leather-Wrapped Bar Ends
After leather bar wraps have been sewn, coiled, or braided on, we want to cover up the cut ends with the perfect finishing touch, both to hide and protect the leather ends from the elements.
The simplest finish is a simple strip of electrical tape - it's no muss, no fuss, and it stays on pretty well. You can even dress up the electrical tape by cutting thin strips of colored electrical tape to create a pinstripe effect.
But for a classy, vintage finish, many turn to old-fashioned twine to cover their bar ends. Some have concerns that electrical tape won't stay down with time and use, that it might lose its gumminess or start to fray. While others like the look of a more natural material to end cap their beautiful natural leather wraps, in a complimentary material palette. This technique is often called "whip tying".
What is a Whip Tie
A whipping knot or whipping is a binding of marline twine or whipcord around the end of a rope to prevent its natural tendency to fray. The whipping can be made neat and permanent by tying it off or sewing the ends of the twine through the rope.Wikipedia, Whipping Knot
Borrowing a trick from sailmaker's knots, we can cover the electrical tape wrapping on a type of thread in the whipping knot. This will protect it from fraying and also waterproof it.
Which Type of Thread To Use
The traditional, retro-grouch choice for whip-tying was a rough jute twine, like the kind used for gardening. This method was popularized by Rivendell Bike, who now sells hemp twine.
But you can use just about any thread you like. Popular choices include carefully wrapped coils of hemp twine, artificial sinew or waxed thread.
The more waxy it is, the less need to waterproof it. With traditional jute twine, bicycle mechanics would cover it in a coating of shellac to prevent fraying. A low-tech alternative to shellac is simply watered-down Elmer's Glue.
On our bikes, we use the same waxed sailmaker's thread used for stitching on sew-on wraps, with a thin coat of watered-down Elmer's Glue.
On our website, we sell a separate listing of an extra length of waxed thread in our 3 standard colors (Black, Dark Brown, White).
