To shape the under body we will use an adhesive lead sheet, known as Zonker Tape. Cut a section as wide as the hook shank and leave space for the hackle, the tail and the head.
Carefully let go the paper of the adhesive tape and turn it over the hook shank, cutting it as seen on the picture.
Once we have made the first cut, round up the lower part to resemble the shape of a minnow. Be careful not to cover the hook gap.
Cut a section of Mylar tube long enough to cover the lead body and also to tie at each end.
With the black thread, tie the front section making sure the Mylar tube is closed evenly. There is a little trick to do this: first, tie the thread on your index finger so it does not slip away. Then, place the thread on the Mylar tube where we will tie it, and make a loose turn so our index finger remains close to our chest and the bobbin on the opposite side. Then, pull in opposite directions with our finger and the bobbin, so that the thread makes an even circle and starts closing, avoiding a View more...
Closing the front section and cutting the thread, change the thread and use the red one to tie the tail section as we did before, but let some tube overhanging to make a tail. Tie and trim. It’s time to cover the body with epoxy and let it dry.
Tie a duck or partridge (or similar) feather by its tip, combing the barbells towards the tail of the fly.
Keeping the barbells towards the back, wrap the feather to make the collar of the fly.
Pick a nicely barred rabbit strap, as fine as possible so it does not lose transparency in the water, and tie it firmly right before the collar, but without touching it so it does not ruin it.
You can add some Jungle Cock or similar feathers at the sides. It makes the Zonker more elegant and also more effective. Finish a neat conic head.
Finished fly. Ready to have the rabbit strap tied at the back.
Carefully lift the rabbit strap and re-connect the red thread. Wet the strap, open it up with a needle and tie the red thread until you make sure that it will stay firm. Tie and then cut the thread. Carefully comb the rabbit strap towards the tail.
