Cam chain tool - bozboz - 17-07-13
Been trying to find an old post about a good tool for riveting a new cam chain -never needed one in the past I've been fortunate enough to have the guides on the 'outside' of bikes not slap down the middle! Anyway I've now given up with the search so what does everyone recommend?

When I did mine http://foc-u.co.uk/index.php/topic,6858.msg64647.html#msg64647
I borrowed a pro-motion style tool
http://www.ebay.co.uk/itm/Motorcycle-Chain-Splitter-Breaker-Link-Rivet-Riveter-Repair-Tool-Bicycle-Bike-/261115809640?pt=UK_Hand_Tools_Equipment&hash=item3ccbb70f68
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
