Magnetized Assault Canon Terminator

After painting my Terminator squad from the Assault on Black Reach box, I decided to add a Terminator with a heavy weapon.
The big dilemma was : "Assault Canon or Heavy Flamer?"
And I though : "Take both of them!"

So I decided to magnetize them on my terminator. I drilled some 2mm holes and glued the magnets inside.
I still have to paint this, but here are the pictures with the weapons :



Notice the little icon of the Iron Hands casted in green stuff.
I'm currently assembling some assault terminators with Thunder Hammers and Storm Shields, so more to come!
