Here is the fly pattern sheet for the Copper John Nymph.
Create pattern variations using different colored Ultra wire. I use Copper, Red, and Blue, but Ultra wire comes in many colors. A good resource is John Barr’s book entitled Barr Flies.
Materials | |
Hook: | TMC 5262 or Dai Riki 730 #8 – 20 |
Thread: | Uni 8/0 black |
Bead: | Gold bead to match hook size |
Weight: | 10 – 15 wraps |
Tail: | Brown goose biot |
Body: | Ultra wire |
Thorax: | Peacock herl |
Wing case 1: | Thin skin – black |
Wing case 2: | Pearl flashabou or Mirage opal tinsel |
Hackle: | Hungarian Partridge or brown hen hackle |
Wing case coating: | UV resin |
Directions:
- Slide bead on hook and place hook in vise.
- Place 10 – 15 wraps of lead on hook and slide forward and snug to bead.
- Begin thread on hook, covering lead and position thread at barb.
- Tie in goose biots with curve extending away from hook. Continue thread wraps over biots and onto lead to create tapered body.
- Begin tying in copper wire directly behind hook eye and on top of hook. Wind thread to barb and back to eye. Wind wire forward to 75% mark. This method will create a nice taper and add weight.
- Move thread back over copper body to 50% mark.
- Tie in one strand of pearl flashabou or Mirage opal tinsel.
- Tie in thin skin with dull side up
- Tie in 3 – 5 pieces of peacock herl by the tips and wind forward to bead.
- Select a hackle feather and clip off the tip, creating a “V”. Place feather over top of fly and position so hackle tips touch hook point. Hackle should lie along the side of body.
- Pull thin skin forward over thorax and tie down.
- Pull flashabou forward over thin skin, being careful to center on thin skin and tie down.
- Whip finish.
- Place a drop of UV Resin on wing case and use bodkin to cover all of wing case. Allow to cure.
Note:
The key to tying any fly is proportions. That also applies to utilizing the right size wire for a Copper John body. Here is the recommended Ultra and lead wire sizes for a variety of hooks.
Hook size | Lead wire | Ultra wire |
12 | .020 | Medium |
14 – 16 | .015 | Brassie |
18 | .010 | Small |
20 | none | Small |
