Pete, I snapped the old one out with some side cutters but I like the soldering iron idea better. I've had one or two of these split on me over the years and slip around. It probably doesn't help that these get soaked with smoke oil most of the time due to their location in most engines I've seen. It seems like this was probably an expensive way to actuate a microswitch from a manufacturing perspective. Gotta wonder how these were assembled in the factory.
Marty, I'm not too worried about it slipping at this point as this first one is an experiment. I was more concerned about one of the cam halves falling off and binding the drivers at speed. Being that they are CAed to each other I don't think that's a danger. Like I mentioned, the PLA seems to take to CA quite nicely. I ordered some 00-80 screws to assemble the next one. The force it takes to actuate the switch is like ~40grams according to the tech sheet so with the height of the switch set correctly, I don't think the switch actuation will bother it. There's a lot of DCC cams out there in the market that go together like this.
