Dean's CDC Caddis

January 2014



                               Fly Pattern: Dean's CDC Caddis 

            Tyer's Name: Dean Childs
            Date: January 2014

      Fly Originator and History: This is a Dean Childs original. Dean has taken the 
    elk hair caddis another step by adding Cul de Canard (CDC) to the recipe. 

                                How the Fly is Fished
    Suggested line and leader:  Floating line with a light tippet.
    Suggested retrieve:  Slow retrieve with an occasional twitch.   
    Depth: On the surface or in the film. 
    Comments: If fishing is slow, try adding a sparkling pupa on a 6 inch dropper 
    to the fly. Continue to fish even after the caddis sinks.

                                Fly Material
    Hook:  #12-16 dry fly, Tiemco 100 or equivalent.
    Thread: 6/0 UTC green
    Body:  Bright green CDC feather
    Legs: Bright green CDC feather
    Wing: Elk hair
    Collar: Bright green CDC feather
    Other:  "CDC Bench" or two small plastic "Office DepotĀ® Brand Cubicle Clips"  
    (refer to "Preparing CDC Hackle" below)

                                Tying Steps
    1. Hook. Tie in a thread base from about 1/3 of the way behind the eye to a 
    point above the barb of the hook.
	
    2. Body.  Select a long CDC feather and tie it in by the tip, above the barb. 
    Wrap the feather forward to the hook's mid-point, twisting the feather as you 
    wrap to give the body a segmented appearance. Try stroking the fibers towards 
    the back as you wrap to give the body a fuzzy appearance. 

    3. Tie off the feather and cut off the excess material. 

    4. Rib.  From the mid-point, wrap the thread towards the bend, wrapping in between 
    the body's segments.

    5. Legs. Refer to the section below, "Preparing the CDC Hackle" for details on 
    how to perform the following steps. Once you have completed Steps 1A-9A, move on 
    to the following step:

    6. From the bend, wrap the CDC "rope" forward to the mid-point. As you wrap, 
    stroke the fibers rearward. 

    7. Wing. Clean and stack a small bundle of elk hair. The wing should extend past 
    the bend of the hook as shown in the picture above. 

    8. Mount the elk hair in front of the body as you would for a typical elk hair 
    caddis, leaving room for the hackle and head.

    9. Continue wrapping a thread base from the 1/3 point forward to the eye. Run 
    the thread back to the 1/3 point.

    10. Collar. Select a CDC feather and prepare it as you did in Steps 1A-9A (below).

    11.  Wrap the collar forward just short of the eye, stroking the fibers rearward. 

    12. Clear any fibers away from the eye, and form a small thread head. Whip finish 
    and apply head cement.



                                Preparing the CDC Hackle

       

    Use a CDC Bench (left) , or two small plastic 'cubicle clips'

 

    1A. Set the shaft of the hackle feather not more than 1/8-inch into one of the 
    slits of the CDC Bench, or capture the shaft using one of the plastic clips. 

    2A. Using a tooth brush, lightly brush the CDC barbules upward, 
    so that they are standing up.

 


    3A. Trim off the excess CDC that overlaps the sides of the bench or clip.

    4A. Use a clip to capture the barbules. 
 



    5A. With one hand, open the slit or clip and then pull the other clip up to 
    remove the CDC and expose the shaft.



    6A. Use a sharp pair of scissors to cut shaft off of the CDC, leaving only the 
    barbules in the clip.



    7A.  Use a very sharp bodkin or a sewing machine needle to split the tying thread 
    (which is hanging on the hook after completing the body).



    8A. Place the CDC into the split and then allow the thread to rejoin, trapping the 
    CDC. Release the clip.


 
    9A. Twist the thread to the left until a rope is formed
