Hey there, internet! I'm in the process of building a Big Mek's Stompa, using primarily the main Stompa kit and the several shoeboxes full of Bitz that I've acquired overtime. For the arms, though, I used the 'Cannon' arm in a different project of mine (A battle fortress,) leaving me with just the huge Chainsword arm, which I converted into the 'Cannon'. (It resembles something between a railgun and a missile platform.)
All this to say, I still need to build a Lifta-Droppa arm, I don't want to shell out fifty bucks to get the Forgeworld arm, and I don't really know where to start. Does anyone have any tips for what I can use to build this arm? Like I said, I've got a ton of orky Bits lying around (As well as plenty of Space Marine bits,) as well as a little plasticard and styrene rods. If you've done any scratch-build projects, have seen cool ones online, or just have ideas, I'd really appreciate your input!
