Wasn't sure where to put this post, so I'm putting it here. Basically I'm starting a Howling Griffons army and I want my Captain to stand out. I really want to have him in Terminator Armour, and give him not one but two Thunder Hammers.

Then I realised I have no idea how I would achieve that, seeing as how I have never converted a single model before.

So, little help? I'm just wanting ideas on where to start.
