Just thought I would show off some pictures of my latest project. A looted wagon built from a Space Marine Rhino.
The Boomgun is on a removable turret so that I can easily switch it up to use as a transport or heavy support unit.
Here's a close up of the Grot riding shotgun.
UPDATE:
I wish I had thought to take some WIP pics of it. most of the conversion was made with sheet styrene (plasticard) that I got from a local model shop. I also went over the entire model with my pin drill and hobby knife to make bullet holes, scorch marks and damaged armor.
The Turret is built from a 1/72 scale T34 tank model, it was kinda small but bulking it up with plasticard made it look ok. I also used a couple of items (ammo box and jerry can) from a tank accessory kit I bought.
I made rivets out of .5mm plasticard that I punched out with a leather punch.
