This is one that I've been keeping to myself for a while now. I didn't want to show him until I was confident in the design I had the germ of this idea way back when I fist picked up my Classics Inferno at original retail, which as you know, is some time ago. I finally managed to scrounge up a junker to get going on this project. The crotch and thighs are from a Beast Machines Tankor. The head is an Armada Prime head. The brass hinges you see are all from the HOME DEPOT (a "big box" hardware store, for those not here in the States). They're called "middle hinges". They're typically a bit loose out of the package, but a few drops of Krazy glue worked into them and they can have an excellent firmness for transformations. The ball joints are from a wonderful little building set that I found in a Dollar Store. Glues used are, so far, Brush-On Krazy Glue and Zap-A-Gap for the tough spots. I used a bit of Quikplastic putty to get the ball joints in the ankles secured. It takes a while to dry, but it sticks to plastic really well. I've put a lot of work into this boy, but he still has a LONG way to go. I got the idea for how to do the trailer hitch/ shins from the Deluxe TF PRIME Optimus toy. Other random design elements have been pulled from various other Prime toys that are out there as well as my own ideas of how he should be. In the earlier pictures, you can see the evolution of how I planned to do the cab shell roughed out in paper. You can also see a size comparison with Inferno. He's taller now. I admit, his proportions have gone a bit "Tallgeese", but I think I can live with it. Please feel free to ask any questions about the design and building methods.
