I'm not too sure about chopping up a Kasrkin to make those crusaders. I'd be more inclined to green stuff the armor bits on the fatigues, and that helmet isn't quite right for kasrkin.
I totally agree, I don't want to lose time ripping appart a metal Kasrkin. I'll add some GS to the IG fatigues and make them look like Kasrkin, Karskin, err Kraskinwhatchamacallit...
So, here is the follow up for the molding process :
The pour, part 2 :
The block :
The tadaaam :
I frakked it up. If you take a look at the 1st image, there is a sprue bit that would serve as the main spilling duct. I put it too close the side of the lego, there for now, at the bend, there is a hole ...
Since I am in a test phase, I'll try to fix with rubber bands a piece of plastic card and will try to cast.
An another hand, I pushed too hard on the backpack when molding the first half, therefore there are not much details on the second side of the mold ...
Anyway, more soon, once I've done a few more progress.
