For repinning my euro-cylinders (and also us-cylinders) I got this nice kit from multipick-service (it's the last picture on the page) it works REALLY well and they also have a pro-repinning guide with some great pictures on the site (pdf-file is in the same link).

On the picture - product 8117 - the tool for removing the clips/rings is also used on us locks and most of you know it.
On the other hand, to put the clips/rings back on (without bending them and making sure they are applied with the same pressure all the way around) you can buy product 8118, the mounting pliers. But that thing is nearly 220$ - for a pliers.
I thought that was just plain crazy and the mounting pliers was the only thing i did not buy from the set. The site though, is fair enough to add this comment to the pliers:
"The price of the special mounting pliers (Article No. 8118) is relatively high. Alternatively, fine common pliers can be used to compress truarc rings during mounting."
Today I went to a hardwarestore (Denmark) and found that Ruko (big danish lock company) actually sells the exact same pliers - also for 200$!

The very helpful person in the store agreed with me that the price is way to high, but as we went to look at the normal pliers we found out that none of them would be able to fit the rings perfetly and mount them without bending or damaging.
Is this pliers available in the US? All US lockpickshops only seems to sell an inverted version of product 8117 for mounting rings but I don't think that would work on the EU rings, since they don't have the two small holes for the pliers to fit into.
A long post - any ideas?
