I thought I'd just add all my stuff in this one thread, to keep things simple. I've almost done all the conversions for my chaos dwarf team consisting of Rackham models. Best part, I won't be painting this team myself, so I thought I'd post the before pictures before I send them off.
Bull centaurs
Nothing major with these two, exhanged arms. Made the other one slightly taller by adding a few sections to his body to make them the same height.
Minotaur
Hands converted.
Some chaos dwarves
Added horns so they'd look more like chaos dwarves. One of these was posing bareheaded with this other foot on top of his helmet, which was on the ground. I carefully removed it, then removed half of his head and attached the helmet. These still need some green stuff work. Symbols, and other fixes.
Some hobgoblins
Nothing much done with these, some arms/hands converted, the ball. Carved the horns off their heads (the ones later added on the dwarves).
I'll probably get the team back in two or three weeks (I hope!). Will post more pictures then.
Some stuff I did with my nurgle team, namely rotters.
Hands and heads changed. One still needs a new head. Still missing some greenstuffery on the heads, swollen tongues and torn skin.
Here's a pic with all of them, (two from the previous thread)
Plus I made some counters for the UW team. I'm not sure if I totally copied the small goblin with the foamfinger from someone else, or was I just inspired by Inkpwn's dwarf fan. If I did, let me know and I'll give credit.

Coming soon - Underworld Blaggards, Black Monolith Carrions, New Gorgoth Crimson Gears & Naggaroth Nightwings
