I made a couple of the cam clamps. I feel like I followed the videos pretty well. The clamps work, but if I tighten them around 90 degrees like Paul does in the end of video 3, the pressure just forces the cams to spin back to where they were. If I spin them more, 180 degrees or slightly less, then they stay. But at that point its too much pressure so I need to position them loosely first where the jaws don’t touch, then tighten them to that point. ANy ideas what I did wrong or if I can tweak them somehow?
