I've always been a sucker for painted interiors, so for the current batch of chimeras I'm building, I'm adding interior details.
So that the interior will be visible, I hinged the rear ramp.
I did this using a #66 drill bit to make a hole through the hinge and then add an axle using a staple.
The old chimera model doesn't have any flooring so I added some using some tread-plate I had purchased for building the Fortress of Arrogance.
I next added a bulkhead using plasticard to separate the forward crew compartment from the troop compartment. I added some details like a hatch from the Leman Russ sprue (I always take sponsons) , a fuel tank for the hull-mounted heavy flamer and a voxcaster.
