This was the first scratchbuilt vehicle I've ever made for my new Ork Kult of Speed Army. I'm very proud of it - it took me three weeks to build with a lot of plasticard, glue, paint, and love.
Some of the smaller details I like to point out -
1) Spattered Tyranid Spore Mine - I went out and bought the Battle for Macragge boxed set for the terrain and ended up with some spore mines that I thought would be a neat embellishment for the front of the battlewagon. I added the grot with a stick and bucket who was sent out to clean it up, although I find it highly likely that a git like him'd be pokin at it hard enough to get it to blow up at any minute. I liked the idea of the spore mines
2) Impaled Ultramarine (?) - Orks consider the color blue to be lucky, and my orks were just thrilled when they found they picked up a hood ornament. They chained him in place and he's now become both a good luck charm for the wagon and an ominous sight for the enemy. He's made from a Macragge marine, which was a real pain because the Macragge marines all come with pin-and-socket joints in static poses. A lot of people comment on this part when they see the wagon on the table.
3) 'Looted' Twin-Linked Rokkit Launchas - courtesy of a Whirlwind I bought for cheap off e-bay. They helped bulk out the front and add that extra orky touch.
4) Magnetized Weapon Slots - all of the weaponry (The top Zzap Gun turret and the Bolt-on Big Shootas) are able to stick anywhere to the bed of the vehicle, as it is magnetic. This allows me to swap out weapons and change equipment based on the game - the 'bed' of the battlewagon can fit up to 5 Bolt-on Big Shootas (two on each wooden 'turret' and one facing off the back), and the Zzap gun is able to pivot to face any direction so that it can fire independantly of the wagon's heading. The magnets are strong enough that you can hold the vehicle upside-down safely without any of the weaponry falling off.
5) 'Ded'Ard' License Plate - obligatory.
6) Working lights! This was my first adventure into wiring -anything-, so I was very pleased with how it turned out. There are three lights powered by a 9v battery; two foward-facing headlights and one interior light to show off the driving ork and his steery mekanism. These lights are turned on by holding the push-button switch on the rear right side disguised as a valve.
7) Grots! Extra grot hanging off the left side of the vehicle, and one of dems misbehavin' gits tied to a spear on the top of the left rear.
A WIP page for the battlewagon exists that showcases pictures from initial concept sketches to the final painting stages. It can be viewed at http://www.fusedcreations.com/adam/wagonblog.html - the pictures are arranged in chronological order so that the full construction can be viewed from beginning to end. You can also get a look at some of the finer details of the wagon if you are interested.
