Decided to jump into Orks, and build a Walker themed list. Thought I'd join the ranks and post progress here, to keep me going.
Here is the list:

Progress on it so far.
I've since added the Exhaust pipes and 1 shoulder pad to each of the Kan units (to tell which models belong in which units), sanded the bases and sealed them. I've got the Big Shoota units arms together (not glued on until painting) and I'm working on the other 2 units arms next. Need to find 2 more Grotzooka bits, but shouldn't be too hard. The Morkanaut has had most of his conversion work finished, just missing some wires for the Imperial Knight head in his Klaw and that will be ready to go. Hope to be priming and putting the Base colors down soon.
