To do this you'll need a bolter & a plasma pistol like those in the picture below.
On the plasma pistol you need to cut along the length of it just below the coil until you get to the little groove that runs a round the pistol, you then need to cut along this groove from the bottom until your to cuts join up.
Now the second part of the post, I was playing Greg in the shop the other night when he told me he thinks I mad & judging from what I've been doing to some rhino's since then I think I've got to agree with him.
So what is this madness you ask, well I've decided to paint the detail on the inside of the rhinos
I went one step or two beyond that with one of them.
