A while back I posted about a mechanical Thunderwolf mount I was converting from the old, metal juggernaught model I started. This all began way before the plastic models were announced, but with the pace of my work its only just now that I can bring you a semi-completed model.
I've managed to get the mount a basic paint job, and even construct a basic Iron Priest to mount onto it - I need to finish the servo-arm, and seriously embellish the armour, but the basics are there enough to make it identifiable on the battlefield. I've even had a chance to run it out a couple of times, and although it hits like a true sledge-hammer, it dies just as easily without any invulnerable save, and only a few wounds in the unit.
and here's the priest on the wolf:
From a boxset of direwolves, I've created 4 Cyberwolves to run with him, I've filled in the many gaps in the models, and sculpted fur onto a lot of the models, though I've left areas of the "skin" and bone to show, and painting them up in metallic and grey colours gives them a nice cyber-look. Below you can see the whole unit together:
