Lets move from infantry models to something with a little more umf - tanks!
With the 7th Ed codex, many of the Ork vehicles got kick-ass new kits. Sadly, the Looted Wagon wasn't one of them and, in fact, would eventually be removed entirely by the time we got to the 8th Ed book - fortunately, it did reappear in White Dwarf a few months later.
It's roughly the same size as a Leman Russ and is a beautifully detailed resin kit that works just perfectly with the new Ork look (as if it was designed too). Its super easy to build, consisting of a just an handful of parts but still has a fantastic level of detail.
Now, as awesome as this kit is, it did need a little work to allow for all the Looted Wagon wargear (e.g. Big Shootas/Rokkits, with and without a Kill Kannon, Deff Rolla, etc).
I started with the Big Shoota options. Instead of using the assault cannon that came with the kit, I magnetized a Big Shoota in its place.
I also added another magnet on top on the turret. It has my 'Longteef' banner to identify it as part of my Blood Axe clan, but it can be replaced with a cupola mounted Big Shoota (not pictured). That gave me two Big Shoots but I needed a third. So I used the big flat area on the front armour, added a third magnet and built a mounting bracket out of plasticard. I then magnatized that and added the Big Shoot from Kromlech.
Given the mounting point and the guns are all magnetized they can be removed/swapped, so I naturally added the other Kromlech guns (Skortcha, Rokkits, Kannon, plus Big Shoota) - just to have options :)
I now needed three Rokkit options. I used 2 of the existing magnets and added one more magnet in the smoke launcher (on the other size of the Kill Kannon).
But just to keep things interesting, what it the Rokkits were firing!
The Rokkits where made using the old Forgeworld Ork vehicle weapons kit. The Rokkits were cut free of their launchers. I took a wire and bent into a somewhat haphazard flight path and put one end into the Rokkit and puttied a magnet to the other. I then rolled a ton of green stuff balls of varying sizes to represent smoke blooms and built up a smoke trail, starting with the larger ones at the end working up to the smallest. The 'bubble' effect gets mitigated when they are painted and the cracks get filled up.
Next post the conversions deviate from just wargear and go slightly off the rails.
