This 5 man Grey Knight squad are to based on Grey Knights immediately after the Heresy. As such they have Nemesis Force Weapons in the style of those on 1st edition Grey Knights, ie: Halberds with storm bolters built in.
I opted to use the older metal Terminators as a base for the legs as I find them to be much better posed than the plastic ones which seem to me to be a bit too widely spread. Adding GS to metal is more difficult than adding to plastic, I'm not entirely certain why that is but I would advise beginners to use plastic models as a base.
The Grey Knight plastic torsos are unusually deep compared to regular Space Marines so I used no spacer in between the front and back. The NFW has had its blade removed and attached lower down so that a cut down bolter would fit atop of the blade. The bolter barrel had to be replaced so that it was in a better position. The added =I= symbol also fit perfectly and the cable was my first try out of my new TubeTool from Masq-Mini and I'm very pleased with it.
The backpacks are nearly done and just require some detailing. The final piece of the puzzle is adding the arms. I've lengthened the arms (using plasticard spacers) and greenstuffed over them to add the necessary size. When I'm working on individual bits like this and I need to put them somewhere for the GS to cure without getting damaged I use a large blob of poster BluTac (sometimes I also add temporary pins to hold small pieces by).
Should have another update of the squad very soon, with a size comparison.
