Scratch built Battlewagon deff rolla

Here's a couple pics of a deff rolla I scratch built. Its for my 4th battle wagon, so I didn't want to have another upgrade sprue one since I already have 2 of those. Anyway, nothing too difficult here. The arms are grabba klaw arms and the roller is a cardboard tube with plastic card ends and patches. Its basically the same size as the official one, so it shouldn't create any problems in game.

I've just started painting up the battle wagon as well, so I'll spray this black and give it the same treatment before moving ahead with the rest.
