Step 1: Cover the hook shank with lead wire. Begin a little way round the hook bend, make tight windings, and remove the excess wire. For deep running nymphs use two layers of wire. For the first layer use thicker wire and finer wire for the second layer and form the smooth shape of lead underbody. For very heavy nymphs use tungsten wire (but it is not easy to work with). To avoid displacement of the lead body while you are tying in the other materials, you can add a layer of super glue on the shank before you wind on the lead wire.
Step 7b: Use a pair of scissors on the back abdomen and carefully trim all extending fibers, to make a nice tapered back to the fly.
Step 13b: Pull the back shield tight and secure it with several winding of tying thread.
