I'm looking to convert an Ork Nob for my greenkins Kill Team so he has a Big Choppa and a Kombi-Skorcha.
I don't think this is a legal wargear combo in regular 40K so I wasn't surprised this option wasn't available in the Nobs box I bought (excellent kit by the way).

Not being very experienced with conversions I though I'd ask here first before I start cutting things up
Has anybody already done this type of conversion? Are there practices to be avoided?

Tips, tricks and pictures welcome
