I added a big putty roll around each receiving part and pressed the chest part on them the way it would be when assembled (I also used saliva to be sure the fresh Duro wouldn't stick to the wrong part). This gavec me the print of the chest part. Once dry I only had to cut off all teh exceding material and do a nice putty blending to reach this state :
Another great interest in using magnets to assemble parts is that you can paint less parts (the chest goes for both mounted and on foot versions) but you can also give the mini different attitudes :
|Dreadaxe, you're my weapon and I will always love you, you know that?|
|Morning everyone, my name is Kaleb and this is Dreadaxe, my daemonic axe aiming right at your skull.|
And at the end of his journey, I can even assemble him as a chaos fiend in a "Pete Taylor way"
