Hello!
The biggest model I've ever built is without a doubt the most fun to build also.
So how do you start on the Brass Scorpion?
first things first: you need two Defilers. duh!
other essentials: modeling knife, clippers, plastic glue, green stuff, you know the drill.
The Tail
of course, the most noticable and unique thing of the scorpion is the tail. the tail is built using two defiler claws and your scorpion cannon.
you only need to use one of the back halves of the claw that attaches to the defiler itself (on the left here) and two of the other ones.
you'll notice that the front half of the claw has on one side a slot were the claws themselves go in and on the back a single gear-like device. what you will need to do is cut the back gear-like thing on one claw so that the holes will line up directly.
The Gun
now if youre going to do it as i did, with the hellblaster volley gun, heres how to do that.
if you are going to use the two-twin linked reaper auto cannons, as it is in the picture, I'll explain that later.
for the volley gun, glue it together as normal but dont put on the wooden back on it (duh)
cut a slot in the claw were the gun will go. the gun is going to be lined up with three barrels along the top. cut it so that the back of the barrels will line up flush.
glue the gun on now. as for the cover, i used two of the leg covers side by side. one side is bigger then the other, so make sure you did it evenly. the bigger sides should go over the gun so it'll fit
to put the cover on, you'll need to cut the blades off of the top. i put them back on in the slits of the cover.
now glue the two halves together
i stuck the back of a thin back of a file through the center hole so it wouldnt move around.
The Body
take the two defiler bodies. cut the reactor portion off of the front one right behind the last leg socket. file it down so they line up straight and flush, but dont glue together yet. you need to put on the demolisher cannon and hellfire cannons first
youre going to have a big divot in the middle. i used a claw covering to cover it up.
