I got to this point by cutting circles of plasticard that were 1 cm smaller in diameter than the wing section below it. I then cut circles out of one side of the larger circle. As the larger circles got smaller the holes cut into them got larger. Thus the tapered look for the wing.
Here it is from another angle. I know the tip looks messy and the curves are not exactly smooth BUT once I gap fill with green stuff and sand it smooth... It should work the trick. (Knock on wood).
I am beginning to doubt this plan however because the wings are starting to look rather thick as it is.
Will have to see once I have a working wing master.
In other news I found this little gem on the internet. Looks great!
It is called a Trinity Tomb Crawler:
It is advertised as: Large miniature: approximate height of assembled Crawler is ~90mm.
It retails for 33 Euros... Never heard of the company though... bitspudlo.com
Will have to see if this pops up in GW's next wave of Necrons... If not I think I will give one of these bad boys a go...
