It's not DIY, it's the standard screwed master link. That one is a DID, but other NJS chains are similar.
@Pifko: The chainline is 46.5mm, which matches the Mavic Ellipse hub with an EAI sprocket and a 0.4mm shim under the sprocket. More pix on my blog http://jorj.co.uk/pivot/entry.php?id=28
The back of the crank wouldn't need machining if you used a chainring the same thickness as the stock one (or rebated the Goldtec one at the other 4 bolts), and that would move the chainline down to 46.0
