I had built this guy and started painting him shortly after his release, but since I didn't have an army to go with him I set him aside for other things. To start my conversion I removed him from his base and removed his choppa (I'll have to find a model to put that on!). I decided to go ahead and not remove his shoota since it would be a huge pain and it looks cool. With everything out of the way, it was time to start adding the mek stuff. I wanted my Big Mek to have a power klaw and kustom force-field. As I looked through my boxes of Ork stuff, the only power klaw that really stood out to me was the one from the Assualt on Black Reach Warboss. With the help of my modeling saw and a few minutes later, I had my power klaw and the warbosses body just may become my base for my converted Mad Doc Grotsnik.
