One of the knobs on my Arca Swiss P0 Hybrid that controls one of the geared movements keeps falling off. I can't tell if there is a screw inside the little hole on the knob that is still there and just needs to tightened, or if the screw is missing altogether. Does anyone know what kind of tool is used to tighten down the knob? If the screw is missing, I assume I will need to contact Arca Swiss in the US for a replacement screw, but I will still need an appropriate tool to tighten the screw. I have a feeling I am not the first one with this issue.
Thanks.
Thanks.
