The Legs

We will combine the legs of the High Elf Archer (A) with the feet of an Eldar Guardian (B ).

Detach these three parts using clippers. You will need to remove the High Elf's feet where they meet bottom of the robe. The Eldar Guardian's legs must be cut just above the ankles.

Notice that the archer's robe has a sort of satchel on the back that will also have to be removed. When you put everything together, you'll notice that the legs will be longer than on the original model.

The Waist and Torso

Get the archer's torso (C). Cut just above the belt. This belt is all that you will be using. (D). You'll also have to remove the strap by filing it down, and narrow the width of the belt a lttle bit.

We are going to place the female Eldar Guardian's torso piece (E) on top of the belt. For this, you will need to trim the base of this torso to about the middle of the third abdominal armour plate. Try to make sure that the torso piece is properly aligned with the top surface of the belt piece. In our example, the belt is at a slight angle, and so the bottom of the torso had to be filed to match this angle.

The Back

This is part of the conversion that needs the most precision, because you will need to trim the Guardian's back so that it matches the shape of the head, the dorsal crests and the hair.

The entries have been removed as well as the whole bit above the shoulders and around the neck.

Carefully examine the differences between the photos of the original back(F) and the converted piece (G).

The Dorsal Crests

You will have to saw off the two crests from the classic Seer (H) and position them on the Guardian's dorsal "winglets." (I) These "winglets" will need to be trimmed down so as to create a flat base (J) on which to place the Seer's dorsal crests.

Try to make sure that they are as symmetrical as possible.

The Wraithbone Loincloth :

To make the bits that hang from the belt, we are going to use some runes from a Guardian Sprue as a base (K) as well as the runes and gems present on the Catapults of the Guardians (L), and the heart, emblem of the Biel Tan Craftworld, which can be taken from a High Elf quiver (M).

The Left Arm :

We'll use a glove taken from an archer's arm (N) and placed on a guardian's arm (O).

The classic Seer's Lance (P) has been separated from its original hand and attatched to the newly-created arm..

The Right Arm

Once again we'll use an arm that comes from the archers (Q) and another that originated from a shuriken catapult (R). We will attatch to these the pistol from the metal Dire Avenger's arm (S).

The Head

The crest and goatee will have to be removed from the Seer's head before attatching it.

The Cape :

The cape will be placed squarely on the shoulders.
Note how the lance is in contact with both the cape and the robe, for more stability.

The Hair

Finally, the hair falls naturally in place between the dorsal crests and right at neck-level. All you'll need to do is slightly trim the tip of Archaron's horse's tail.
