I am going to be using a Trygon torso and 2 Trygon head plates (not pictured), plus a set of Carnifex legs and tail, standard Carnifex head and standard Carnifex armored plate (not pictured either).
I removed the 2nd and 3rd ridges from the armored plate, I would later go on to remove the first two back vents as well.
Torso modifications step 2:
Here you can see the Carnifex armored plated and additional green stuff vent that has been added to the torso. The Carnifex tail section has been lengthened so that the torso and tail/waist will fit correctly. The tops of the Carnifex legs have been widened and Trygon head crests have been cut into armor plating for the thighs.
Leg conversion process
|Thighs removed from legs|
|Thighs cut in half|
The Carnifex thighs were removed with a jewelers saw, the cut in half with a standard hobby razor saw. The thighs were then widened by gluing the halves to a 1/8 inch thick piece of plastic card and sculpting/sanding it down to match the original contour. Your can see the white plastic card in a photo above this.
|Trygon torso vs Hive Tyrant torso|
Beginning to blend the Carnifex armor plate into the torso and have added the first 2 green stuff vents.
