So this was my first attempt at a real cosplay, I failed to take many pictures of the build as it was rather rushed but the result is pretty good.
There is an aluminum frame running up my back, attached the that is 3 lengths of 13mm hose running in 4 directions. ( 3 lengths per direction ).
The segments of the arm are made out of 15mm pipe lagging, duct taped together, with a line of yellow electrical tape running though the middle to give effect.
The claws are crafted out of EVA foam, and glued together
Then add welding goggles and a (ladies ) trench coat
