straight to it, excuse this it will be crappy crude but bare with me and you'll have an awesome little bad ass. Now what you'll need Hailstorm Screwdriver Something sharp (in my case a box cutter) Now remove his arms completely from his torso, in order to do that you need to remove Only that screw on both arms Then we open the shoulder wich are these And with that picture you see what were going to do Pop off the brown treads and cut out the sunken part following the hole you see in the previous picture.( maybe someone can take a pic of the arm without the cut so I can post it for future reference?) Make sure you level the area around the screw hole where the shoulder joint will pass. here's what I mean Now were almost done we simply need to make alittle room for the shoulder piece to slide smoothly now forgive me for this picture because its butt ugly but at this point you need to slice that small block between the two wheels and the corner under it next to the point where the shoulders fold. And that's it! Piece him back together we went from this To this And yes he still transforms!
