Firstly I drilled a hole. 8mm wide to accommodate an 8mm wide magnet. Now at this point you want to ensure the polarisation you use now goes accross the entire model. I did the head and glued a magnet in place. Then made sure I had a main body polarisation which would be used for all body magnets and a limb / plate polarisation too.
Then drilled 8mm hole for magnet in the elbow before it was glued to the torso. After the magnet was glued inside.
I also washed more armour then. . .
Painted the Hydraulic housing Runelord Brass then washed with a mix of Warplock, Klear and water (so it shades the recesses).
