What you're looking at is made up of exclusively 1 Terminator model from the Black Reach box set. The only thing I added was some black stuff, crazy glue (works extremely well with black stuff because of the porosity), and 2 copper pins I made from wire. No other models were involved in the making of this one, no extra bitz, if anything it actually gave back some bitz.
Basically cut off the left leg, waist, and head. Cutting through the waist took a lot of pressure. For the head, first I cut below the chin, then scribed a bit with the knife, did the same on the inside where I saw stress marks, put more pressure at the neck, went all the way through the hood :s at least it made my job easier.
Tried to paste the hood and chest parts together but it was very delicate and kept coming out of alignment. Finally said screw it and pushed some black stuff into the torso, put the chest in with partially attached hood and aligned it there. I molded some black stuff around the neck area to keep that stylish line, then put some more on the back of the head and pushed it in place, molded the excess and sculpted a ribbed duct on the neck area like what you find on the back of the knees.
So there it is, I think it looks a lot better, and here he is next to an unmodded one for comparison.
