Well, despite some major Migrane attacks I was able to do some work on Friday and Tuesday.
So here is a rather large update:
I started working on the actual launch ramp.
Here you can see the "organists" station.


A typical ork contruction (and a great way to get rid of some of my leftover plasticard).


There are still some details to the organists-station, but you get the idea.

I started to modify a Ork biker to be the organist.


And I started on the Grot-bombs....well actually more planes than pure bombs. And instead of Grots I have real Orks manning.
Bomb 1 in launch position

some details...


And a fingerpost, so the Orks know which way to go *grin*

more details

But still missing all the rivets..
