When I did mine http://foc-u.co.uk/index.php/topic,6858....l#msg64647
I borrowed a pro-motion style tool
http://www.ebay.co.uk/itm/Motorcycle-Cha...3ccbb70f68
this was fine for splitting the chains
BUT
and as it says in the pro-motion instructions this is intended for riveting either hollow pins or at least hollowed ends as it drives into this with a blunt mandrel and splays the end. Where as pins like on the DID link I got have square solid ends and should be mushroomed over rather than splayed
So how I did it - I assembled the inner parts of the link and then pressed on the outer plate, checked the link moved freely and measured the same width as the other links with a digital calliper. Then my son held the back of the chain against a block hammer, with a flat ended punch held at an angle i peened over the sides of the pins in two places on each using my smallest hammer. Using the punch means an extra hand is needed, but it gives you a lot more control. I checked the spread with the calliper. Happy with that, checked it still moved freely, happy days !! Could barely distinguish between the one I did and all the others
