I've been asked how I made the two-handed weapons for my Iron Warrior Auxiliaries and I thought I'd make a tutorial, cuz I've always wanted to make one. It's simple enough and not too hard to get right, and you get to have Claymore-wielding Space Marines

Now, we begin quite simply, with gathering all the stuff we need:
1) A pair of bolter-holding arms (sans bolter). I’ve used the ones from the Chaos Tac Marines with that big spike sticking out from the hands.
2) A left-handed fist and a right-handed fist
3) A Space Marine torso
4) Plasticard (1mm thick) for the weapon, or if you want to take a premade one from somewhere else do dat.
5) Paper Clip
6) Hobby knife, clippers, a pin vice and a good paper-clip-clipping-device (clippers aren’t made for clipping metal and get damaged doing it)

Step One
Start with fitting your arms to the torso with blue-tac and make sure you can get the hands to overlap without the arms being too far off their place on the torso. This is Paul, he’s my volunteer for this tutorial:


Yay it works! Now OFF WITH HIS HANDS:

Screaming will get you nowhere, Paul.
Step Two
Okay now we turn our attention to our two fists. Drill a hole through both of them and see can match them up to hold a sword handle, and remember, blue-tac is your friend; don’t glue anything yet! Just thread the paperclip bit through both fists so they’re holding it, and then try and match it up to your Space Marine’s severed wrists:


"LOOK AT MY LOLLIPOP!"
Wonderful! Now all you’ve basically got to do is glue it all together, BUT! First let’s take a look at the weapon shall we? This next bit of the tutorial is for people who want to make their own weapons out of plasticard, so if you’ve got a premade weapon you can skip this bit. This is for swords and sword-like weapons only btw.
Step Three
Get a bit of plasticard and cut the basic shape of the sword, a bit wider and longer than you want. I left a tab at the bottom so I could hold it easier while I’m shaping the blade:

Step Four
Now you basically just shave down the piece of plasticard to look like a sword blade, or whatever you want it to look like. You can do this with a file but I normally use my hobby knife. I place it at an angle to the plasticard and just scrape it down to the end of the blade (away from your face!), shaving off plasticard until I get a nice edge on the sword. Give it an edge and a tip, on one side or both, maybe some spiky bits along the blade, whatever you want. I’m just gonna go with a basic European-style Claymore sword:

Yeah, the pic doesn't really show all the hard work I put into getting an edge -sniff- but you get the idea.
Step Five
Attaching the blade to the hands…
Now, I don’t know if this is the same for everyone, but my paper-clip-clipping-device leaves an edge on the end of the bit it clipped:

This is normally a bit annoying, but it actually works perfectly for this. If your paper-clip-clipping-device doesn’t do this, then you can just file it down to make an edge. You need to essentially pin the blade to the hands as a mm-wide strip of plasticard is not a large enough surface to get a good bond between the weapon and hand. But you attach like so:

If that doesn’t quite explain it I have a crappy Paint diagram:

So then you should end up with this:

"I AM NOT OVER-COMPENSATING!"
Hope this was useful, and that people actually need this!
