I wan't really sure where to put this so General Discussion seemed best. I have an XCS 2" post and I have a Jerry Hill Balancing Bracket with his 2" docking collars. The docking collar over the course of the day constantly slips under the weight of the camera and eventually ends up resting under my upper electronics box. I know that this pressure on the box can't be good. I've measured both parts with a micrometer. Post 1.999 collar 1.946. So in reality the clamp should bite without a problem but yet it keeps on slipping. I tried a piece of tape around the post but it didn't work either. Has anyone else ever had this problem? I think a thin plastic ring would take care of it but I'm open to all suggestions.
