As we all know I have been talking up a storm about thunderfire cannons, but I have been proxying them in my games. Well because of the tournament in a week I am looking at actually building a pair or even three of them. So I scoured online (google) and came across a few images which I think serve as a good basis for a conversion.
Imagine this more "orkified" and mixed with a bike.
In addition to this, I am looking at building a techmarine without a servo harness as I think they look really silly. So I am contemplating using standard space marine as a basis with a powerfist with a ungerslung flamer built in (think huron or vulkan) and in the other hand a decked out plasma weapon to count as a twin linked plasma pistol. To represent this better armor, I would attach ork plates and probably some plastic card to make them look bulkier. So would this be a suitable conversion for a techmarine?
