maybe for weathering him you ought to have a look at how model railway modellers weather their models. it's more sort of limescale dripping and dirt rather than scraped edges. if you want to see really dirty locos I'd suggest looking for british rail steamers from the 1960s, they really didn't bother cleaning them at all. If i'm right about the engine's origin (a train is consists of more than the locomotive) then either fleischmann or Marklin should do models of a similar if not the same loco type
make it a thomas the train cross-over or make it your own made up character, and just make up a random name for example if its an decepticon: darkstack autobot: railrider. idk
ditto! Needs a few Space Shuttle parts! At first I thought this was going to be an Astrotrain Masterpiece! Now that would be, astro-nomical!
that would rock, but my skillz are just level2 need more XP... few months "grinding" perhaps Level3 required
TODO: -balljointed head (currently now head-motion whatsoever!) -probably turn him into another Optimus Prime -try to articulate the legs somehow (this is gonna give me headaces)
update ... point of no return.... I'm scared... and might even trashed this project, but will see until other leg is completed!! (but in to much pain @ the moment )
MAYBE: -use armada jetfire for Astrotrain??? (if it's partsforming Level2or3 will be enough... If I intergrate... Level6 )
