Yeah, it's an ingenious but PITA system that requires new techniques. You have to compress both of the spring loaded pins on a given link simultaneously. I used a feeler gauge to hold one side in while I pushed on the other side. Another idea I toyed with was using a piece of a playing card to do that. The feeler gauge technique worked fairly well, however.Does anyone have any tips or suggestions for the spring bar pin and collar system? With the tools I have I am unable to get the spring bars to release. I don't see a guide as to which side (arrows etc) and my pin and collar tools are just not engaging. So any information is appreciated.
