I made a second Bucher conversion for my Gutbuster/Beastclaw army. I used Blood Bowl ogre. It is a little bit smaller than usual ogors, but not noticeably so, and has really nice dynamic pose. Gives some variety to otherwise quite similar and static ogors.
So I put Ironblaster ogor head on him and hands from regular Ogors. That required some greenstuffing and cutting, but it was easy enough and I hid the flaws with shoulder plates. Cauldron is also from Ironblaster/Scraplauncher kit, filled with bits.
All in all it was fun little conversion and Blood Bowl ogre suits well, I like the forward rushing pose and how he drags forth fresh meat for his cauldron.
