This is a full-on in depth tutorial on how I build customs from the ground up. I call this technique "Re-structuring". This does not mean this is a tutorial on how to build a Masterpiece Slag, it is only intended to show the process of a re-structured build. ^^First we lay out our base components. I like to use pre-existing figures as it allows you to utilize there ratcheting joints, ball joints, or other articulation points. ^^Get a rough idea of how you want him to transform. This mode it your most important because you'll be working towards making something out of this mode. ^^This layout could be used for several different transformers as it's a fairly basic configuration. (Arms fold away, legs roll over waist) This was originally going to be a 1/25 scale Scrapper........ but we'll make Slag instead. ^^The legs are donated from a Cybertron Primus figure. They do not roll over the waist as is but offer a knee joint that would allow it to do so. We begin by mapping out an area to be removed. ^^I only notch out as much as I need for clearance. You never know how somethings going to shape up closer to completion so make minimal cuts. The waist not fits within the lower legs. ^^Scale is an issue in this case. The upper body is too wide in relation to other figures within it's size class. We'll need to narrow the body. ^^The arm hinges are a primary point so don't alter those. By cutting away the excess body fat we...... ^^.....narrow it down like so. ^^Once happy with the scale of the body, you can create structural supports and install mechanisms that will come into play later in the build. In this cause, there's a square tube that runs vertical down the center of the body. This will allow the neck of the Triceratops to extend. (Some pre-planning is required.) ^^I now begin building other components that will help determine scale along the way. The Triceratops head is important the help insure the rest of the dinosaurs body is in proportion. It'll also determine how much space the robot head gets to move around in. ^^With the dino head basic structure complete. I build my robot head and base plate. Check to be sure he can look up and down and side to side. The neck extension is in place and a forward flap installed which will become the alt modes lower jaw. ^^You'll need to find a suitably sized face for your build. The helmet size can be altered so focus on getting a face that within the realm of other figures in the same line. (The construction of this particular head will be featured in an up and coming tutorial titled "head construction and alterations."
