How To Attach A Braided Leader to Silk Fly Line

Brasstown Creek sells quality Phoenix Silk Fly Line.

The information below for attaching Braided Leader to Silk fly Line is the system used by Brasstown Creek, Inc.  While  this works for us, there are many other methods, some of which may be better – but this is what we use.

1 This is the elegant box that Phoenix Silk Fly Line arrives in.
2 Phoenix Silk Fly Line comes with a container of Red Tin Mucilin Line Treatment. Brasstown Creek also sells genuine Red Tin Mucilin which is made by Thames Fishing Tackle, Ltd. in England.
3 Here is the simple Tension Device we made to aid us in securing Braided Leader onto Silk Fly Line for Leader (angle iron, rubber bands, spring clips, bar clamps).
4 Use your best guess with the initial spacing between the angle irons of your Tension Device; the space between angle irons depends on personal preference. Remember you need to leave enough room to easily wrap the Silk Fly Line.
5 Here is an example of how the Tension Device can keep constant tension on fly line (example uses cord rather than Silk Line). As you see, rubber bands are useful for a lot of things.
6 Brasstown Creek also sells Phoenix Braided Leader. We will use this Braided Leader in this example.
7 This is a photo of the Butt end of the Braided Leader. Note that by the nature of its manufacture, Braided Leader has a hollow core.
8 The Silk Fly Line is on the left in this photo, the Butt end of Braided Leader on the right. Our intent is to carefully thread the Silk Fly Line into the Braided Leader.
9 Here we are beginning to thread the Silk Fly Line into the core of the Braided Leader; do this without tension on line (our example shows the Tension Device clamps only to assist in photo; don’t apply tension until Photo 16).
10 Brasstown Creek uses Cyanoacrylate glue as well as the silk thread to secure the the Silk Fly Line and Braided Leader to each other. Here are some items used with the Cyanoacrylate glue (inverted mixing cup, toothpick, tweezers, Cyanoacrylate glue for semi-porous materials)
11 If you use a toothpick to apply the Cyanoacrylate glue, you get better control of the process. Here we place a drop or two of glue on a mixing cup to facilitate application with toothpick.
12 Dip the tip of a toothpick in Cyanoacrylate glue (some glue will initially be absorbed by wood, use your best judgment to insure sufficient but not excessive glue on toothpick)
13 Now apply glue to the Braided Leader at the furthermost point to which the Silk Line is inserted. Cyanoacrylate glue will penetrate the Braided Leader and adhere the leader to the Silk Fly Line. Do not be excessive, this is only to enable tension to be applied to the Silk Line and Braided Leader
14 Here is another photo showing the application of glue to the Leader-Line junction. We then continue to sparingly apply the glue with the toothpick along the lengh of the Braided Leader into which the Silk Fly Line has been inserted.
15 At this point, the initial glue application has not dried; notice that end of Leader is a bit frayed from the insertion process.
16 Once the Cyanoacrylate glue has dried (this doesn't take long), clamp the Silk Fly Line in one Spring Clamp and the Braided Leader in the other clamp. Stretch the rubber bands when applying Clamps so that when released, tension is placed on Line-Leader junction.
17 In this photo we show a spool of YLI #100 Silk Thread. We use Black, but the color is your choice. We use a fly tying bobbin to wrap the thread onto the Leader-Line junction.
18 Attach the YLI Silk Thread at furthermost point where Silk Line is inserted. We use a Constrictor Knot (see the following URL for example of knot:
19 Tighten up the Constrictor Knot before you begin wrapping the YLI Silk Thread over the Silk Fly Line - Braided Leader junction.

20 Here a toothpick points to the tightened Constrictor Knot
21 Cut the tag end of the Silk Thread. Do not cut too closely at this point; you can wrap the tag end under the silk thread wrap for neatness.
22 Begin to wrap the YLI Silk Thread toward the Butt End of the Braided Leader; wrap over the tag end of the silk thread you just cut.
23 Here is another photo of the beginning of the wrap
24 Here is a clClose up photo of the wrap as it approaches the Butt End of the Braided Leader. Gaps in wrap are pretty much inevitable, but make sure they aren’t too wide, both for cosmetic and structural reasons.
25 Before you wrap to the Butt End of the Braided Leader, trim off the frayed portion as close to the Silk Fly Line as reasonably possible. Some frayed ends remaining really isn't a problem.
26 Now continue the wrap
27 Now you are almost to the end of the first wrap.
28 Wrap over the trimmed Butt End of the Braided Leader and continue a bit beyond onto the Silk Fly Line.
29 The first wrap is now done; now you have to wrap back the way you came (wrap over the first layer).
30 Here the second wrap is progressing toward the start point (furthermost point where the Silk Fly Line is inserted)
31 Here is a close up of second wrap. Wrap as carefully as you can in order to cover as many of the minor gaps as feasible. By this time, any gaps are mainly cosmetic rather than structural.
32 Now you are nearing end of second wrap.
33 Finally! The wrapping part is done. Now apply a thin coat of Cyanoacrylate glue over the entire wrapping (again using the toothpick for better control); the glue prevents unraveling of the thread until it can be securely tied off.
34 Now cut the wrapping thread, leave sufficient slack and tie a good Constrictor Knot.
35 Tighten the Constrictor Knot; apply a bit of Cyanoacrylate glue over the knot.
36 After the last bit of glue dries, closely trim off the tag end of the YLI Silk Thread.
37 The wrapping, knots, and glue are now done.

39 This photo shows the Braided Leader-Silk Fly Line junction and the tip end (loop) of the Leader. Now just attach your monofilament loop-to-loop.
